Matt Owen: I'm planning to take on an engine replacement job on a 2003 Buick
Rendezvous and I'm wondering if anyone can tell me if the engine will come
out the top on this thing. Can I just pull the front clip for the room to
do so? Or? I don't have a car lift to drop it out the bottom, so I don't
want to tell the guy I can do it and then find out when it shows up that I
need a lift.
Bud E: Been fighting a recurring problem for the life of the car ('02 Rendevous).
Occasionally, I get a crank, no-start condition. Car will start, run for
a second, then cut out. Attempts to restart then result in just cranking.
A shot of ether will cause it to run for a few seconds. No codes when
scanned. The crankshaft position sensor was replaced (on back of car) by
the shop as well as the fuel pump, and I replaced the PCM and coil packs /
plugs / wires. It seems like every time something gets replaced, it's fine
for awhile, then it will act up again a few weeks later.
Strange thing - I had to replace the front crankshaft seal (under the
harmonic balancer). The other crankshaft position sensor sits there. I
did not replace this. After I put the balancer back on and tried to start
it, it showed the crank, no-start behavior, where it was fine before I
started. I tightened down the crankshaft bolt (I think the balancer was
not fully seated), and low-n-behold it started up. I read this sensor has
nothing to do with starting, but seems to be more than a coincidence.
Car is OK now, but I feel I never fully solved this issue. Thoughts?
Jason Harvey: I have a 2001 Chevy Venture, that Im thinking has a blown head, The night I
bought the vehicle it ran fine had no problems other than a shake when
accelerating, but that's not the issue. I started driving home the next day
after purchase, got about 3 miles from where I started, and overheating
begins, and speeds slows to 20 mph, I shut it down immediately. Waited on
it to cool down and got home 3 miles later again getting hot. I changed the
rad cap and added coolant from napa, just to be sure it wasn't a blown
head, I checked for water in oil and oil in water, and even checked trans
fluid, didn't see anything wrong at the time. Drove it about 7 miles and
loss heat, then overheating and shut it down again, got to a mechanics
shop, they did a block test, not showing blown head however the shade tree
mechanic noticed it had sludge on the valve cover inner wall and said well
its had a blown head gasket and looks like they drained the sludge and
replaced old engine oil. This is evident-ally a scammers way of selling a
blown head gasket vehicle, he said to get some blue devil pour and go head
gasket sealer. Tried that, but bled the cooling system after refilling and
didn't over heat, ran good and had good heat. So thought this fixed the
problem. Next trip on the way home its overheating again, so I checked the
bleeders maybe there was air in the system still sure enough pushed a lot
of air out before getting coolant. After bleeding it no problem but since
then in order to drive this I have to bleed the coolant each time and add
maybe a cup of coolant to top off. Is this a blown head or is it the intake
man. gasket? I don't have a lot of cash to dump into this, and hoping for
an easy fix but figuring its not going to be. Just today the trans started
shifting hard not sure if that helps with all I have said but, it is up to
date info as to what I have seen go on with this vehicle.
andrew morrison: hello, i have a 1998 pontiac grand am se with a 2.4L. i also have a 3.4
with the tranny attached that i pulled out of a 2001 alero. would you by
any chance know if i could put the 3.4 in my pontiac or would there be a
lot of new parts needed? i have all the parts from under the hood off that
alero so that shouldnt be a problem unless its just different cv axles
needed. Any help would be greatly appreciated
Carmel Amour: How do I replace my pcv valve in my 1999 Oldsmobile alero? Where dose it
plug in at??
Luther Humphrey: thanks for your insight... haven't checked to see where that white hose
goes..but when i checked the code it says P0404 ...so it seems to be the
egr is causing it to go into limp mode
Ashlee Holbrook: Anyone know an easy way to get the trans cooler lines hooked back up to the
transaxle? These 3400 don't give you much room to move around in. Thank
you to anyones advice.
Chris Connell: I have this same engine in my 2001 Aztek. The engine compartment has a
different configuration but the engine is the same. My fuel pressure
regulator went bad on me so it would leak fuel but only when it was very
cold outside ( like below zero) so I didn't mess with it for a few years
until just recently it started leaking more often so I replaces it which is
a bit of a pain to get off. they cost about $100. About 2 years ago I let
the engine get a little to hot and it damaged the head gasket and costed me
$1400 to fix but that was a little my fault for letting the engine get that
hot. The biggest design flaw in them is that the head is made out of
aluminum and the block out of cast iron so when they heat up the different
metals expand at different rates which warps the gasket and causes the
leaks. Now though I have to replace the alternator which means I have to
LOWER THE ENGINE just to get the alternator out. The engine compartment was
really badly designed. Thank you for the video BTW :)
B Mckinnon: I would like to compliment you on your discussion. Your advice is spot on
and you're helping a lot of people. Some advice to those of you that are
leery of doing your own repairs. Never do the repair yourself if it has to
be done in a hurry. This is where mistakes get made. Always be organized,
take your time and fully research the repair before you do it. Good luck.
Baba Tee: I have a 2004 Oldsmobile Alero 3.4 Litre, bought it off a friend of mine,
had a nightmarish experience with Overheating, messed up the engine that
came with it, replaced it with another engine, and the overheating
persisted, read through some opinions on the web, told my Mechanic to check
the manifold intake, he checked replaced the gaskets but the overheating
persisted, fortunately my Mechanic is as dogged as i am, he insisted that
there must be a reason the overheating won't go away, so he disconnected
the Complete exhaust system and allow the the car to run, noisy though but
that solved the problem. the catalytic converted was bad and was blocking
the free flow of the exhaust, he remove the catalytic converter and
replaced it Voila, overheating stopped, now my Alero is my favorite car.
Overheating seems to be one of Alero's negs. I hope this helps.
Dr. Logan: Does anyone know if you can swap a Pontiac Grand Am 3.4 with a Pontiac
Montana 3.4? I think it would work, it's the same engine, just have to swap
out some connections, some pulley's, and possibly the transmission
dipstick. Let me know... Please.
Proto_The_Brave: i have a 2000 monte carlo with a 3.4 and it dies when i stop at stoplight
or brake i think its the egr value but not sure
Bud E: '02 Rendezvous leaking alot of oil. Seems to run down mainly the back side
of the engine. Oil pan gasket seems OK. I did replace the front
crankshaft seal under the balancer (what a PITA!), and that seemed to help,
but I would like to try to tackle the remainder of the leaks. What's the
next most likely culprit? Valve cover gaskets or Lower Intake Manifol
Luther Humphrey: that line you have your hand on at 2:37 attached to the plenum.. where does
it go and is it needed? All i have left of it is a small piece the rest
broke away and no clue as to what it goes to
DON KAIN: I just bought a 03 Aztek with 160,000 on it, drove it twice engine sounded
pretty good strong yet. So I bought it, within 24 hours I drove it home and
then to work not issue's went to leave work started it up and the engine
noise was bad. The first thing that I thought of was a rod, then valve's
floating, or piston or pistons slapping. I was hoping it would go away when
it warmed up, run it for about 15 minutes no change so I decided to try
putting in some Murphys Mystery Oil in it. But it stayed about the same if
not a bit loader. Went to my second job, and a few hours later when I left
the same thing, hoped it would quiet up but it didn't. So stopped at
Walmart on the way home and bought some STP Oil additive the small blue
bottle very thick oil improves viscosity and helps with engine wear and
stuff. But after putting it in there is no change almost as if it is
gradually is getting louder. It sounds like a diesel pretty much now, don't
know what to think now other than go and ask a mechanic. And I contacted
the guy I bought it from and he said it was fine, I don't know what to tell
you!?! Anyone have any Idea's other than small claims court!?! Thank you!
Darryl Harris: Also the timing chain housing gasket often springs a leak they are hard to
spot also. Check under car with on lift our jack right under power steering
pump right in the oil pan area. Delphi also put junk pressure regulator
valve on here causing it to either be sucked up into the intake through
vacuum lines or leak pass the diaphragm and can be a big fire safety issue.
There is a recall for the3800 not these so look out for that ,both engine
FPRs leak past the diaphragm inside the fuel pressure regulator
Jamal Muhammad: 2000 monte carlo, it makes a very loud screeching noise after I have had it
running for about 15 minutes....whether I am driving or I just have it
running in the driveway, I cannot figure out this noise. You can hear it in
the car and you can hear it outside the car, even in the house you can hear
it, that's how loud it is, any ideas?
my03fx4: Can I swap a 3400 out of a 2002 grand am into a 2003 alero with the 3400?
The guy at the junkyard says it won't work.
Brenda Holm: I had (and I am thinking about getting back) an 02 pontiac aztek. Runs like
a scalded dog most of the time. However, after sitting over night the next
day when you start it and try to take off it would chug, lug, spit and
sputter. Shut if off for about 45 minutes or so.. start her back up and run
like a dream all day long. Traded the car... between us and the new owner
we have changed: plugs, wires, fuel pump, fuel filter, a tiny vacuum hose
on the charcoal cannister, another part on the cannister sorry cant
remember what it is called and ran a can of sea foam through it with no
change. Problem is getting worse according to new owner, takes longer to
"warm" up enough to drive and she said when she removed the gas cap
completely the car dies... thoughts?
denis perez: I have an alero 2000, 3.4L , I already change, fuel pump, sparks, spark
plugs, egr valve, idle air control, ignition switch, map sensor, throttle
sensor, and my engine still shake in neutral or stop sign, its feel like
going to shut off, what could be the problem?..... somebody give me any
idea, this touch my pocket really bad.
Clayton Z: 03 Grand Am GT1. Had Motor replaced about a year ago. Now I'm leaking
coolant in a steady stream from head gasket although No water in oil. How
often do the heads go Bad or get warped. Wondering if just replacing the
head and intake gaskets would be the fix or should I also replace cylinder
jamie parfait: Easy way to clean the EGR valve on the 3400 series motor..... off a 2000
kendell fontenot: does anyone kno wat a light tappin sound can mean on a 03 oldsmoible alero,
i did nothing but clean nd shave the cylinder heads?
Timothy Tegmeyer: I have a 2004 Monte Carlo with the 3.4 in it. About to hit 97K. Any advice
on what to do for routine maintenance around 100K? I was planning on doing
some AC Delco Platinum plugs and an AC Delco wireset. I always wonder what
I should expect out of this motor in terms of lifespan. My money would be
that the 4T65E transmission gives out before the motor ever does.
Richard Hamilton: Currently replacing the heads on an 04 aztek 3.4. I'm ready to install the
new heads but i'm not sure how to adjust the valves. I looked at the repair
manual and it says there is no adjustment for them.
ArnoldKnows97: Is it possible to get a new one of these engines ? Or replace it part for
part with a newer engine that fits 2002 rendezvous.
Chris Wilickas: I have an 2001 impala 3.4. Starts great but when you hit the gas pedal the
motor surges. (reeves up and dies back down) very little power when you
hit the pedal. I can Idle and the engine runs perfect. Any ideas
jeremy fahrni: Thank you. I have this same engine in my 02 Montana. This is really
helpful. How long do you think changing the intake manifold gasket would
take your average backyard mechanic?
Coryhughes00: Im assuming intake manifold gasket. Getting air in the cooling system,
losing coolant, over heating issues. Fluids do NOT mix though, so thats
good. I bleed the air from the line every day or two and add some coolant
until I can fix it right. Any recommendations on what types of gaskets to
fix these with? My last 3400 blew THREE head gaskets. I heard there was a
good set that lasts longer now. Any tips woul be great! Thanks
Ryan Haas: Do yourself a favor, get rid of the car. 3.4= garbage. If you wanna stick
with GM, get something with a 3.8. Bullet proof engines.
81kmoua: I have a 2002 Buick Rendezvou 3400 sfi engine, there is noise coming from
the engine. When you turn on the car the noise comes on and when you step
on the gas it gets louder almost like a whistling sound. I checked the
power steering fluid and it was out and I filled it, same nosie . I
replaced the water pump and still nothing changed. My friends told me that
it could be the harmonic balancer is bad. But I don't know where it is
located. I would like to know what the problem is. Please any advice would
be great at this time.
Edson Valdez: I have a 2002 Grand Am GT with the 3400 and it has hard time staring, I
drive it around works fine but if I go to the store for about 30min to an
hour than its hard to star again. I tried turning the ignition to run a few
times before starting seems to help out just a bit, but it still has a hard
time. Im thinking its the fuel pump. I also change the fuel filter and it
was pretty clogged. Any tips?
sterling5989: Mine is being hesitant especially when you put it into gear. It has that
annoying ticking noise when it does it and the whole engine vibrates bad.
Chris hauser: lol i managed to crack my Head over my 5th cylinder on my 02 ga gt... It
caused constant misfires but still ran, also burned gas like a mofo... BUT
i no longer have the car because i upgraded to a Cadi
DJR5280: Do the 3.5 L chevy malibus have head gasket failure issues ? Mine is a 2005
and it seems like i have excess air in the cooling system. I never had a
problem until i cracked the bleeder screw by the water pump and ever since
it seems like i have excess pressure. I have drained the cooling system and
bled it and no luck.
mak69007: My 01 Chevy Venture, is Idling to high, speratickly, but becoming more
constant. I'll shut it off, start it back up, and it will run fine for a
bit. I'll be going, then if feels like someone is touching the gas.
Keith c: you solved my idling problem ive had 4months god bless you.That was my
sethhigby: i have a 200 pontiac grand am i recently had the upper radiator hose blow.
i taped it up and filled it with fluid just to make it home about an hr
away. 2 miles from home i pulled up to a stop light and the thermostat red
lined i shut it down let it cool off then made it the rest of the way home.
i changed the hose filled it up fired it up and fluid started leaking from
the front of the engine. I thought it was the water pump. I replaced that
but still seems to be leaking i can't track it down but it is dipping from
the harmontic balancer. Any suggestions. thanks
Joe Garisto: Hi I have 2004 chevy venture and I am having problems starting it up it
will start and then die, I have to hold down the gas for a while and then
it stays on. In the summer I opened up the Idle Air Control (IAC) Valve and
cleaned it out with carb cleaner and it worked for months. I was thinking
of opening up again and cleaning it out again, what do you think? I have a
feeling the plunger is not sealing the seat because of carbon build up.
Randall Cooper: I have a 1999 Grand Am with a blown engine, 3400 v6. Bought a good engine
from a wrecked 2000 Grand Prix and find out its from California and the
emission controls wont hook up. Can I remove that and make it run?
Maryjane Glass: I need someones help I have a loud noise coming from my engine I'm thinking
its the oil pump cuz the slap noise sounds like a lifter and doesn't stop
when it warms up what do I do I'm afraid to drive it and blow the motor
naptownblues: At 2:40 you point out the repair to a vacuum line, I'm interested in the
line underneath your finger and the container it leads to out front. Any
James Bessette: I have a 01 Chevy Monte carlo. My car always starts rough i gotta hold down
gas for it to start. Also once its warm she likes to stall after i sit at a
stop light or sign then turn a corner or something it stalls. I replaced
fuel lines, idle motor, pcv valve, plugs and wires, and fuel filter. What
could it be on the 3.4 sfi...
david long: I'm completely lost. I have a 2000 grand am gt. I had the engine replaced
and it ran fine. No problems until about a month later. Now it sometimes
will either overheat or I will have heat inside the car and loose it and
then I can shut it off let it sit for a couple mins and it'll be fine or it
will just be fine to start. I put a new coolant bottle, new thermostat, and
a water pump off the old engine that I know was good. Sometimes it will
push coolant back out the bottle through the overflow or just air after I
shut it off. The car runs good. It doesn't smoke. Starts easy. Everything.
When it over heats or when I have heat and loose heat the radiator hoses
are both soft when everything is fine they are both firm. Neither one feels
to soft to where it should collapse. Help
MrHamp32: Hey man what s your thoughts on this? I recently changed blown head gasket
on a 2001 chevy impala 3.4 I got everything put back in proper order per
Haynes Man. Engine will spin but wont start. I have about 55-60 psi in fuel
pressure. compressions good and I have spark at every cylinder. check again
this morning to verify I have everything hooked up and tight and no luck.
Sal Perez: Where is the cranshaft position sensor? Is there one or two
Matt Cogar: 2000 pontiac grand am gt. I've noticed when i get to about 1/4 tank of fuel
the car won't start. If i rock the car back and forth while turning the key
to the on position to engage the fuel pump it will tend to start. Inline
fuel filter has been changed. Fuel pump screen clogged? HELP!!!
phil johnson: My 2002 grand am is idling very high around 1500-2000 I have checked the
IAC, TPS, and any vacuum leaks and still can't find the problem any
Kaneshia Wagner: And how often should you change your Relays?
