4.3 issues
1st off, howdy everyone been awhile since posted anything.
ok so I snagged an 89 GMC a few months back and been having a few issues with now. did an O2 sensor, EGR valve. yesterday it seemed like the thermostat wasn't opening at all so I went and replaced it. refilled the radiator and such and let it run and it all seemed good so after the grand daughter left I took for a ride to the store and back and again its like the thermostat isn't opening. kind of wondering if maybe I don't have a head gasket issue. any ideas ?
