Did this video help you?

John Shay: Keep in mind that on Impala 3.4L there is a blue connector that doesn't connect to anything! It has enough length to make it seem like it connects to the Alternator but that already has a connector from below plus the red wire. Make note of this as you are taking things apart. Apparently they didn't want to make 2 separate harnesses (one for USA and one for Australia) so they just use a single harness in both markets. After 2hrs of trying to figure this out I found this out by checking online.

Jordan Perkins: could you use this same video when replacing head gaskets?

Sean Stralo: man you got less stuff in the way still very good video and help me out

WM A. Richards: i like your videos very much ,, if oil dripping out of front value gasket, can i only just change the one

B Logan: Just a quick question - when you pulled up the fuel rail with the injectors intact... I notice the plastic sleeves just below the rubber o-rings that seal the injectors were missing. Was that the case? Some have told me the sleeves get caught in the lower intake and fall into the head.

Purplekush: can I change the gasket heads in this procedure or do I need to take apart the engine more

Brian Kelley: no one uses the quick gas disconnect tool. why, if it don't leak don't take it apart.

Roberto Mora: I used your tutorial everything was fine but the lower intake manifold just broke what could have happened it was one of the diagonal bolts below the throttle I torque the bolts as said in the manual 9.5 ft/lbs veritcal bolts and 18 ft/lbs diagonal bolts

Matthew: My valve covers leak which causes my anti-freeze to leak and thermostat to go haywire. Car runs fine as long as I top off the coolant every couple weeks. I'm looking on here to see if it's an easy fix to do myself but I think I'll pass lol. That's very time consuming work. And very risky to do yourself, as you have to remember everything you took apart. No wonder this is give or take $1000-$1500 to have done in a shop. I just changed all my speakers and my air flow sensor and throttle body myself, but anything that involves taking apart my engine or tranny, I'm leaving that to professionals.

RobbPaulz: i got a 2004 chevy venture and the heater is fluctuating, seems to get hot when engine is working hard up hills or keeping at a steady rev in neutral/ park. This fluctuation comes with overheating as you probably guessed when it blows cool it overheats when it blows warm engine stays cool. So i replaced the belt and water pump. I changed oil cause the light came on after a couple incidents and I had just changed it recently. it was hard to tell if it had orange in it. Seemed a bit light brown under in oil pan under flashlight but no foam. I see no coolant on ground but in the coolant tank seems to be some sludge that is brown, jelly like coating the inside of the reservoir and the neck on the radiator along with some chunks probably decaying radiator or radiator fix additives?. I bled the hoses by the water pump and the reservoir. Seems like the one by the reservoir gives more air then coolant. I wonder if these two are related. I didn't replace or flush the thermostat / radiator. I don't have enough money to keep missing this diagnoses i need to know if it's the head, intake or what have you? It's our only car now and we are relying on it. I got to get busy fixing. i bought a haynes for a tear down. thinking of doing thermostat, if that fails go for head gaskets?

trackspike64: what if your not getting the water in the oil but still loosing water ?? how do you replace the upper intake gasgets cause thats what is going on with my car

A_Disciple: I have a 3.4 05 chevy equinox, and i think im having some issues with this. The car is not leaking water, but the reservoir needs to be topped off every week or so. I was thinking these gaskets maybe because i think the water is getting into a cylinder and burning up. There is no oil at all in the the coolant and no coolant in the oil. This morning when we tried to start it it sounded horrible, like a rod knocking. If these gaskets fail can they plug oil passages and cause intermittent knocking?

David PD: Hello, I used your tutorial on my Alero and it worked flawlessly, helped me so much!
Thank you very much !!

Lucas Juan: is sim process on Chevy monte Carlo 2004????

OfficialAlyshaKelly: So if I use this video to replace a 2007 Chevy impala would it be the same?

brandon smith: So far, I have followed this, step-by-step, to get the manifold out and now I am starting to replace the gaskets. This guy does the best videos ever! Make sure to give 1A Auto http://1aauto.com/ some love and order parts from them. They are great auto pros and they know their stuff!

BrotherKnowtheledge: Thank You

S.Ciprian Ciprian: Over 1000 happy miles on my GM3400SFI after I did the LIM right after your instructions and torque specs. All good, coolant level is fine, oil level is solid. All good! :) Thank's again!

COPYMAN: I've watched all 3 parts of this video series for this model Pontiac and I found it extremely helpful. Thank you for posting it.  But I have to say that ROCKAUTO.COM has the exact same Dorman (615-205) gasket kit for about half the price of 1A AUTO. $43.64  (price includes shipping).   Sorry guys.  My grandfather always told me "my money is better off in my pocket than someone else's"

frankburnsjr: I'm looking for the gasket kit for an '04 Alero, but your site shows that nothing is available for that model year.  I thought the '99-'05 Aleros all had the same LA1 V6?  If so, would the gasket kit that your site suggests for the '03 work for an '04?  If not, would the installation be substantially different than what's shown in this video?  Thanks.
