95 Lumina running hot
My grandpa and I have been trying to figure his 3.1 chevy Lumina out.
The problem is, is that it overheats. You can drive it 4-5 miles and
the temp will rise really quick, but will go down just as fast. I
changed the temp gauge sending unit and thermostat It seems to be
circulating coolant at idle with the cap off. I just wander if I have
removed all of the air via the air bleeds in the coolant system,
because when the temp rises The heater will soon quit blowing hot air
like it is air blocked. If anyone has expirienced this prob. and has a
solution please post it this is my granpa's only car.
