no offence.... but if your asking then it probably isn't something you can do yourself. you have to remove the whole upper half of the engine. valve cover, heads, and anything else that might bolt into the valve cove or heads. which is usually alot of stuff! if you really want to do it though then start by getting a manual at most parts stores. they are about $20 dollars. but the whole head gasket set you need will be between $200-400. if you haven't tried already, then go out and get bottle of radiator stop leak. alot of times it will do the trick. it's not permanent but it will get you by for awhile!
You will need to replace the intake gaskets to fix your problem. The HEAD GASKETS will not be your problem.
The estimated cost for parts and labor to replace the head gaskets on a 2001 Pontiac Grand Am with a 3.4 liter V-6 is $1,685 to $2,230. For this job, the labor alone is estimated to be $1,310 to $1,675.
Between the head and the engine block.
Head gaskets do not go bad on these. You need to replace the plastic upper intake manifold as it is leaking coolant into the combustion chamber. Common problem for this engine.
Purchase a Chilton Auto Repair Manual, and follow the instructions. Remember to take your time and get all of the gaskets you will need to do the work. Head, Valve, Pleneum, and possibly the Exuast Maniflod Gaskets.
Replace the head gaskets.
Any head gasket can blow......but to be honest the 2.8, 3.1 and 3.4 aren't really known for blown head gaskets. Sure it happens, but the biggest problem with some of the late 90s early 2000s was a weak lower intake manifold gasket. Not the head gaskets.
For sure, replace ALL the gaskets involved. When you purchase, ask for a head gasket set and you will get all the gaskets that are used.
the whole set.
Yes you do halft to pull the head, because the gaskets are under the head.
No
In short you have to take the head off, replace the gasket/s and replace the head. You best bring it to a pro.
