SOURCE: my car overheats. it doesnt lose cooling fluid.

dont say how long it takes to overheat. try replacing thermostat,often when stuck close one hose will be cooler than the otherand check the timing,if this is out it will cause symptom. do you have the shroud around the fan still.it assists in drawing heat off radiator.other question is of course:is the temp gauge correct,see if your local garage can run their temp gun over rad etc to see what is hot and how much.or you may be able to hire one

Check the antifreeze for oil, pull your dipstick out, see if antifreeze is in oil or smells sweet or over full, sounds like you may of a bad head gasket. You can also check this by having a compression test done on the cylinders.

The Grand Marquis's have a know problem that causing overheating. The intake manifold cracks around the water inlet tubes on the intake manifold causing it to loose anti-freeze which in turn causes overheating. Mercury has a beefed up replacement intake manifold that cures the problem. It was a subject of an unannounced recall but they would replace it unless the problem occurs. The recall was for 7 years which the 1999 model wouldn't qualify for now. It happened to me and cost about $450.00 (parts and labor) to fix it. I used a local repair shop to do the work. If, after the engine is hot, you hear water/steam coming from the top of the manifold, you have the problem

This could be a broken head gasket, cracked head or block.

Pull the thermostat back out and you should be able to see water flow through the radiator. Make sure the water pump is working.

May have a bad thermostat responsible for overheating and smell. Till resolved turn on heater full blast and open window!
Continue to monitor for leaks and lack of pressure in cooling system. Fill expansion tank to the mark and make sure all hoses and clamps are tight at radiator and heater core.

  • White smoke out out the tail pipe means you might have just blown your head gasket. White smoke is water (antifreeze) burning with the oil.

My fog lights won't work but switch shows power, however when hit the switch can hear the relay on passenger side fuse box can hear it click does that need replaced


Hi, if the light on the switch is coming on, the relay is fine. Unless both bulbs are burned out, the problem is in the wiring between the relay and the lights. I recommend you trace the wiring backward from the passenger side fog light to the power box under the hood to see if the wire is cut. There should be two wires coming out of the power box--one going to each fog light. If the wiring looks good, it is also possible that the ground to the lights is bad.

Your heater core is located up behind your glove box. This is like a little radiator like under your hood. Air blows thru this to heat your car thru the heater. The liquid IS antifreeze, you have a leak in the system somewhere. The fog is humidity due to the leak.

You didn't specify what type of vehicle.
If you have very poor air flow out the vents, later model vehicles have a hepa filter or cabin filter in line form the blower motor to the vents. It can be plugged quite easily and drastically cuts down the air blown into the vehicle. Check to see if they are plugged. Secondly, Check your coolant level in the rad and reservoir. If the windows fog up when cold and air flow is good it could indicate a leaking heater core. Check the passenger side floor for signs of coolant again I don't know the type of vehicle, some heater cores are located at the firewall under the hood.

Where is the outside air temperature sensor located?


Passenger side, just in front of the radiator and recessed behind the bumper under neath the metal brace in front of the A/C condensor near the bottom of the front end. It's nearly impossible to see without bending down or laying on the ground. But if you carefully move your hand along the metal brace you will feel it near the passenger side fog lamp. Pretty easy to change.

1998 lincoln town car


If you notice a 'sweet' smell, or windows tend to fog up, it's your cars heater core leaking. The heater core is located under the dash, passenger side, it's like a mini radiator. The cars cooling system directs hot coolant to it so you can have heat. To change it is an involved procedure.
If there is no evidence of the anti-freeze smell or windows fogging up, and u have been using your air conditioner, it would be a blockage in the drain tube from the a/c. The end of the tube is located under the car on the passenger side , behind the front wheel. The blockage needs to be removed, and will solve the problem. Let me know what u find Curt
