The 4.3 liter Chevy Astro head gasket torque specification is 160 pounds. The head gasket bolts should be torqued in 40 pound intervals.
about 2000 if your lucky

most likely the thermostat, but these vans also have a history of blowing head gaskets...... It would help if you described symptoms

I need to know the location of the oxygen sensor 3 in bank 1 on a 2000 Chevy Blazer. Is it the one closest to Cylinder Head or closest to the catalytic converter. email address is wcannon@knology.net
