Any auto parts store can get you one.
replace the head gasket
it will cost you 200 dollar if do it yourself
No. You need to remove the head(s) and have the head(s) checked for cracks and straightness, then install the head(s) with new head gaskets. Most head gasket manufactured are assembled dry, no sealants.
blown head gasket
You will need a new head gasket if you see engine coolant in the oil. I don't know about the thermostat.
TO SEE IF IT IS YOUR HEAD GASKET DO A PRESSURE CHECK. TAKE TO A RADIATOR SHOP AND THEY CAN CHECK IT FOR YOU NO CHARGE......AND IF IS YOUR HEAD GASKET THE PARTS ARE CHEAP BUT ITS THE LABOR THAT WILL COST YOU......(6HR JOB). I HAD IT DONE......
Cylinder head gasket torque specs on 2003 Pontiac Grand Prix 3.1 L V-6
You are going to need a Chilton's manual for this one.
anywhere from 1200 to 1500 bucks if you havent cracked the head
No compression could mean a blown head gasket, cracked head or cylinder.
Between the head and the block. First, remove intake manifold and exhaust manifold. Take the valve cover off and unbolt the head. Then, pull the head off and you'll see the gasket.
