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
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.
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.
mak69007: My 01 Chevy Venture, is Idling to high, speratickly, but becoming more

Randall Cooper: I have a 1999 Grand Am with a blown engine, 3400 v6. Bought a good engine

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

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?
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...
Matt Cogar: 2000 pontiac grand am gt. I've noticed when i get to about 1/4 tank of fuel

fuel filter has been changed. Fuel pump screen clogged? 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.
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

order to do this, I need to move power steering pump outta the way..
Removed the 3 bolts (through the pulley access holes) but can barely make

David Weesner: I have an 02 rendezvous. I currently have the heads off for gasket
replacement. As you know, parts are everywhere in my garage. It ran fine
before I took it apart, but im wondering if I should replace or have the
valves checked as long as I have it off. I just bought the car and have no
idea of the history. I am no expert on heads and think maybe I should take
them to a shop and have them checked? Is this just asking for a large
bill? I am pretty handy and usually go for DYI and I took it all apart no
problem. I could do the valves with good advice. I am a machinist and have
no problems following instructions. Thanks for your videos! Any thoughts
on doing what is best at this time? Car has 233k so who knows
Albert Eble: 02 Buick Rendezvous. On occasion will start right up, grumble and then die
after about one second. Then won't start, just cranks and cranks. If I
let it sit 15 minutes or so and come back, then usually starts right up.
Runs great once running, no stalls, hesitation or other issues. Problem
only happens once in every 5 starts or so. Fuel pressure is good (58 psi).
No leakage (gas, coolant, vacuum) in engine that I can see. Any advice
what to look for next?
Antwaun Robinson: About how much motor oil do I put into a bone dry 3400 engine?
G. Phillips: I am having a hard time locating parts on my GM 3400 sfi engine. I do not
have diagram or manual. What is the specific name of the hose that is
connected to the PCV? Also, what is the name of the hose that is connected
on top of the air intake duct that is then connected on the back end of the
rocker arm cover? That hose in particular has a plug on the end that needs
to be replace so it can fit tightly in the cover.
MissLLP: Where is the thermostat housed?
Fernando Warren: I have the 3400 in a Chevy venture and when I start it up in the morning it

Joshua Snyder: I have a 99 alero 3.4l. With ~162k miles. The car. died on my wife. I
pulled CEL codes. Only P0300 multiple miss fires. All cylinders receiving
spark. Will barely stay running for 1 minute. Sounds like2 cylinders
missing. I did notice the oil pressure light is on. Any suggestions would
be appreciated. I'm thinking oil pump.

instead of plastic. its worth it.
fatback1980: Hello, thanks again for the great videos. They really helped me change my
intake gaskets and head gasket. I now need to change the egr tube on my
montana. So, do you figure I can reach the nut on the manifold to loosen
the tube from below, or should I tilt the engine forward and get it from
the top? Thanks!
Eric Yoface: I have a 02 grand am and i noticed if i'm in park and i rev the engine a
bit, it goes from 1500 rpm then drops to 400 but it bounces to 1000 then
goes to its normal idle at 700, any thoughts on what can be causing this
issue? also idles in drive really rough like its almost bogging.

Anthony Allender: I have no heat and on occasion my 2003 impala 3.4 will overheat (in the
red) and then drop back down. Recently had intake manifold gaskets
replaced, radiator and heater core flushed. Thermostat replaced also. Does

really appreciate your help.

big bubba: have this engine in my '04 Impala. Have over 175,500 miles on it.
John Paulson: Well I gave up on doing the work myself in fear of creating a bigger mess.
So to the shop it went. A local shop who I very much trust looked at it and
quoted me less than $700 for the intake gasket. Since I budgeted more than
that I will have him check some other items while they are there. New
thermostat and maybe some new coolant lines are in order. He said no labor
on those since we would already be in deep. Fingers crossed the overall
stays under a grand.
