i own a 95 6.5 litre diesel it had no heat i replaced the thermostat, now the
tempature gage goes full and goes down when it wants , when i turn the a/c on the gage slowly goes down. mechanic says my head gasket could be leaking and its been spraying anti-freeze out of the over flow resovoir , but the mechanic knows nothing honestly nothing if the gaskets where leaking the exhaust would have a blue tinge to it, and the main question is the gages??? why do they jump around like that if i take the thermostat out it stops?
