Hello i have a 2001 monte carlo i was experiencing
a leak with the coolant that caused the car to
overheat and leak out coolant as well. However the
leak was fixed but the gauge is still rising as if the
car is overheating but i dont believe it is because
there is no leak or smoke. The gas gauge does not
work properly sp is it possible that the temperature
gauge isnt as well? If not do u think the issue is a
sensor or something?
If you see smoke it is too late, I am suspicious of a blown head gasket, a block check test will confirm or not, you may also want to consider having the system live data scanned so you can actually see what the computer is reading for actual engine temps and for anything else that might be out of specs.
Sounds like you have air trapped in the cooling system. These cooling systems need to be bled after a cooling system service or major coolant loss. The best way to bleed it is with the front of the car angled upwards. Like if you're partway in the driveway. If you have the 3.8 there's one bleeder screw on the thermostat housing. If you have the 3.4 there's two bleeder screws. One on the thermostat housing and, I believe, one near the metal heater hose connector. With the engine off and cold open the bleeder screw(s). Remove the radiator cap and add coolant directly to the radiator until you get a steady stream of coolant coming out of the bleeder screw(s). You may have to do this a few times. These can be a real bugger to get all the air out of. HTH. -Jim
