dwallyworld4: I have this engine in a 2003 Olds Alero. trying to replace the waterpump outside in 10degree weather sucks. It appears the waterpump only goes on one way. We are going to get back to it tomorrow, but my son and his friend apparently had something off and the bolt may have crossthreaded. once we get that out we may be screwed, but if they can get a replacement (they broke the head off) and it still is good enough to go, how do we know it is positioned properly to fit the mount on the engine properly? I am accustomed to a car with a matching tab on the motor to line up with the water pump. There is no such thing on this vehicle, and I am pretty sure it only goes on one way. We could try hand threading each bolt, then remove and turn one to the right for each of the 5 possibilities, but if there is a way to know it would be awesome. The water pump we purchased between bolts has tabs or no tabs. clockwise it would be a tab in the middle, no tab, a tab to the left, a tab to the right, and no tab (from the perspective looking at it from the fender). I am guessing one of those tabs is designated to be the top, but I have no clue which. And if all the pumps for this car are the same I'm still out of luck because they took out the old one without paying attention to that. Being it's so cold outside here and we are stuck doing it without a garage, I really hate to have to try all the positions if someone knows which one is correct!
Thanks in advance.

Zayy Cooln: I have a air leak but mines whistles and white smoke comes out the tail pipe.!!!!!! #helpme

The Brave One: Worst piece of crap I ever owned.

Simon Winston: Anyone knows the pipe right before the throttle body, on the air intake main hose? the other end goes to the engine, under the ignition coils, the computer part. That end has some kind rubber thing, mine ruined because of age. 2001 pontiac grand am. I got code p0300, maybe this is the cause.

Julian Tamayo: I am having an issue with the charging system in an Oldsmobile silhouette 2000, replaced battery, 2 new alternators and still not charging the battery, at times the voltage shows 15.+ coming out of the alternator other times is 3 volts or nothing at all, it seems the alternator is not getting the signal from the computer, any one have any ideas in Fixes. Thank you.

Randal Warburton: I have a 2004 grand am gt 3.4 moter wont start .changed starter and battery still no start .starter turns for 2 seconds then lets go .cant figure it out

Rob Savant: Hope you all are still around. I did a head gasket replacement, took the heads to a shop to have them tested and cleaned. Car ran before I replaced gaskets and now there is no compression. If I loosen the rocker arm bolts it will get compression. Did I forget something? Anyone else run into this and was able to rectify?

ЯyantheDolphiИ: at 2:30 you touched a hose that runs into the big metal intake manifold. What is that? mine just broke and I need to know what i9t is so i can replace it. Thanks!

southdub26: I have the most annoying problem.. it's very intermitant. When driving usually happens once every week or so, I'll be driving and all of a sudden it's like my car is on cruise control the Rpms will stick at a certain spot. If I slam on the gas the power is real sluggish. I can literally let off the gas and the car keeps going. Usually maintains speed for the most part. If I stop and park the Rpms will be high. Usually I'll turn the car off for a second and restart and boom it's gone. Took it to 3 shops , one a trans shop and no one can figure it out. I take gaskets done. Tps done. Egr done. Fuel pressure done. 92,000 miles. No check engine lights no codes. I'm lost please help guys.

mitzi tkach: 04 pontiac grand am lower intake manifold gasket leaked antifreeze into the oil. Replaced with felpro gaskets problem solved. It started to leak slowly over the a.c. compressor which blew the a.c. clutch fuse. That caused a no cold start issue.... seems the fuel injector start pulse circuit shares the a.c. compressor fuse. Would cold start with either then restart all day until cold. Check the a.c. compressor clutch fuse.

Sir Flynt_32: What exactly do you mean by hesitation?

john otto: I know this feed is old but i've watched every video you made, i have my whole engine apart in my 99 olds silhouette, got everything cleaned painted and sad to say all my parts got mixed up, bolts and all, this is gonna be fun, i'm most worried about the vaccum lines

Ronald Rutledge: I have a 1999 Oldsmobile Alero with a broken cam found out it came out with a soft cam that's what the garage is saying so I bought a used motor to put in

Darius Horton: Where would my booster vacuum line be then? Just bought an 04 alero and I just cant seem to locate it.

John Doe: Thanks my kid had the issue and bingo . Put some o rings on the stub and all good . Thanks

Dude Stylez: 05 chevy impala had 160 miles and just developed a ticking noise.. don't understand, I do all proper maintenance on it.

Gamesturbator: I have a 2004 Alero. The yellow vacuum hose you grabbed ahold was broken off (car was in poor condition when we got it) and I've had a dozen guys from autozone and mechanical forums who weren't able to tell me where the other end goes (doesn't quite look like yours in the back). This how mine looks: https://i.imgur.com/aIygLGO.jpg Someone on Scotty Kilmer's website said is a vacuum controlled shift modulator (car definitely struggles with shifting gears). REALLY need to find where the other end goes.

Ramin Taheri: This engine has been cutting out on me and stuttering at around 2k RPM especially when cruising and keeping the RPMs at a constant. I have spent a lot of time and $$ at the dealer and every time they say they've fixed it hasn't been fixed. Now, they are saying it's the catalytic converter but I am not sure I can trust them anymore. Can someone please advise? I would be very grateful for any insight.

Josh Wallace: I have a 2001 Chevy Impala 3.4. Sometimes when i am driving it. An i am accelerating quick or when i floor it to pass someone it will rev up like it's going to take off. An then all of a sudden it starts to hesitate or acts like it's getting to much gas or to much air. But as soon as i let my foot off the gas and hit it again it goes. Other times it will do the exact same thing again. I have changed the fuel filter, throttle body, air filter, plugs and wires. An it is still doing the same thing. Any suggestions???

James Dixon: the name of a lion coming off a Buick 04 with 3.4 motor coming off the water pump running to the driver side going into the firewall anybody know the name of that tube is mine is dry rotted and leaks water
