Hey guys I need some help tracking down whats wrong. I put a new water pump on this weekend along with a new 160 degree thermostat. It was reading way hot at first and then I bled the system, now it's only at about a 1/3 maybe Im trying to pinpoint whats wrong. If its my thermostat stuck open, or my gage temperature sensor.. help please? I may or may not have a problem, I just dont think its getting upto full temp, or if it is is not reading.. Any pics of where your impala or caprices run with 160 thermostats? Thanks, Im just beat, I put a new water pump, optispark, plugs and plug wires (the hardest part), coil, O2 sensors on, and all new seals on this weekend. I now I just want this DONE!
