The fuel filter is located in the pressure line that runs from the fuel tank to the engine, near to the fuel tank.
Keep the engine off for few hours before replacing the filter, to get rid of some pressure in the lines.

SOURCE: monte carlo 01 runs hot, says low coolant but its full

Thermostat is probably stuck closed... Run the car with the cap of the bottle or radiator and see if it starts to circulate when it gets hot... Be careful though because it can over heat and have no coolant flowing.. And also watch for spewing fluid if it get hot at the place you took the cap off.... The low coolant could also mean the radiator is not full but the bottle is... Check for a restriction from the bottle to the radiator.. If you see a sensor on the bottle it could be bad... But That won't cause it to over heat. It'll just say low coolant because the switch is stuck.
Also does the fan come on while it's getting hot?
If not that could be the reason for the overheating.. And the coolant level sensor could be bad telling you it's low
Cap off look for circulation of antifreeze.
At the same time before it over heats make sure fan is coming on. No fan on? Fan fuse or relay could be bad... Also maybe a wire.
No circulation? Thermostate stuck or restriction in coolant hose...Line... Radiator..... And worse case scenario the water pump might be bad.
The low level I wouldn't worry about. Find out why it's over heating first.

Better make sure the fan works. There is a switch on the radiator that turns the fan on when it gets to a certain temperature. It could be the fan or the switch. Your thermostat is not your cap, it's in a different location. (Usually at the engine end of the upper radiator hose) Get the leak check! A good garage can pressure test the system to see what leaks you might have.

SOURCE: how do I change the coolan sensor in a 2002 Monte

the low coolant sensor is on the side of the radiator about 3 04 inches below the radiator cap. Yuo can unclip the wire and then there is a clip I think or it may just push in with an o ring around the nipp;e. So you will have to wiggle it out. I have the same problem. I just unplugged the damn thing. (disconect the wire)

Hi;
If your engine cools down when moving fast, you either have a problem with your water pump or your electric fans that cool off your radiator and a/c condenser. This is controlled by a temperature switch, but these fans should kick on instantly when A/C is selected.

Monte carlo blows cold air and overheats


It really runs hot within a minute of starting ?
An engine that runs hot in a few minutes is often having problems with the water pump or a blockage in the cooling system. The thermostat does not open until 195 degrees which takes 5 or 10 miles of driving.
During that time, the water pump should be circulating coolant in the block and the heater hoses.
A leaking head gasket should be putting extra pressure into the cooling system, and-or dumping coolant into the cylinders which would come out the exhaust pipe. But it should still take a few minutes for the engine to reach the boiling point of 240 degrees.

Had short in fan that killed engine and it want start, 2002 monte carlo


When the fan stopped working did car temp gauge ever max out if so check coolant level to see if still full check oil if there is any white sludge. If coolant and oil are good than you might have a bad coolant sensor which also operates fan and engine a bad sensor can cause car not to start and ever run very poorly

Check the thermostat, if it isn't opening when engine warms up, the coolant in the engine will overheat and make pressure in the cooling system but the fluid in the radiator will still be cold.

Is coolant flowing through the radiator? Possible water pump, radiator blockage, or air flow to/through the radiator blocked or restricted. When the fans come on is there warm air coming from them?
