A co-worker of mine has asked me to give him a hand in changing the head gasket(s) in his 2001 Pontiac Montana. He's going to buy the %26quot;Haynes Repair Manual%26quot; and we have access to a fully equiped garage for a weekend.
My question is... how long should it take to repace? Are there any tips or tricks to replacing them? Anything to watch out for?
I'd rather an answer from someone who's done them before on that type of van, amature or professional.Changing a head gasket on a pontiac montana?It can be done in a day and you should also replace the head bolts when you remove the heads because the bolts are torque to yield bolts and can not be re used correctly because they stretch. Also that motor is noted for breaking the intake bolts when you try to remove them so be sure to have a can of PB Blaster at your side to lube every bolt you can see before you try to loosen them. If the motor was overheated you should also have the heads checked for cracks and warp age before putting them back on. It sucks having to send them out to get checked but it can save tons of time and money if there is a problem with the heads and you don't go through all the work for nothing. Just remember to keep everything clean and follow the torque specs in the manual and you should be alright. Hope I have been helpful.Changing a head gasket on a pontiac montana?well if you need a manaul and you have to ask then its a good bet its going to take all weekend if not longer
since your have to remove top of motor to get to heads im guessing four days amature or a couple if professional
