Question about 2002 Chevrolet Tahoe
2002 Chevy Tahoe Z71
After the car has been running a while, when I accelerate from a complete stop, there is a sound coming from under the truck, also notice a sizzling / popping. Cracking sound when I turn the tuck off after it has been running a while. Sound like a hot pan cooling down.
Replaced the water pump, but I am still losing coolant, although it is NOT running hot, the coolant level keeps dropping in the reservoir.
Did not replace thermostat
Since you are not overheating, thermostat is likely not the problem. Chances are you have some seepage at either an intake or head gasket that is dripping onto a hot pipe when you stop. Leak may be so small at this point that coolant loss is barely noticable. but if you look carefully at all head/block parting lines and check all obvious connections that could leak, you will find the problem. Any white smoke from exhaust?
