SOURCE: Overheating Problem

There are a lot of places it could be leaking from,it could be a head gasget, freeze plug, intake gasget, ect. best thing to do is pressureise the cooling system and look for a leak, and watch the pressure guage on tester. Do you have the right radiator cap? or at least the right # cap. That is something thats over looked a lot, and they go bad too.

SOURCE: loss of coolant (leak) in the radiator. causing overheating

They can be a real challenge to find, especially if the leak is buried somewhere that you really can't see. Then after driving around, the fan and wind spread the coolant all over , making it even more difficult to locate the source. 1st try 'stop leak' which can be purchased at parts stores, you might get lucky and it will fix the problem. Sounds like a good idea to replace the radiator if it's rusty. You could have a leak at the head gasket, or even a freeze out plug on the block. A couple of suggestions to help locate it: pick up a small mirror at a parts store, the kind that folds and extends. Get the car up in the air so you have plenty of room underneath to move around, and securely supported so the car won't fall on you. Clean off any drips or visible coolant. Start the car and crawl around with your mirror and a good flashlight, and wait for evidence of coolant to appear. It's a matter of patience and poking around to find it. Good luck.

SOURCE: I cant seem to locate the fuse block for my 1987

Try turning on your hazard/warning flashers. The DOT 3 fuses are usually right next to each other. Follow the clicking sound.

1990 Crown Vic over heating

engine thermostat is not mention the parts you changed, replace it.
consider the head cylinder gasket, it causes overheats.
a/c is another system, not a part of the system of first.

What is causing my car to run hot with a smell? its 199

The smell is most likely the anti-freeze you smell. You may need a new overflow cap, which over time will not hold pressure like it should and can cause you engine to run hot and lose coolant. It could be the water pump leaking, a hose leaking. Can you see where you may be losing coolant at? How often does it run hot? Do you have to re-fill after it runs hot. If you not having to add coolant, then your thermostat may be bad or the water pump. But losing coolant could be the overflow cap or a hose, and let's not forget the radiator could have a small hole or split somewhere. It's a matter of finding out where or what are it is leaking in.

The crown victoria keeps running hot and need to

Before you get into this involved job I have a few suggestions. First is the pump leaking causing the system to lose coolant. Grab the fan and try to move it from side to side to see if there is play. Next when was the last time the thermostat was changed out. The thermostat can be stuck in a way as to restrict water flow. Another cause of over heating is a clogged radiator. Older cars can have a slug build up in the radiator core causing a significant cooling lose.
Water pumps on a Crown Vic is located on the front of the engine behind the fan. You should really get a service manual as there are a lot of steps in this job that must be done correctly to avoid future problems.
You start by draining the entire cooling system by opening up the drain plug on the bottom of the radiator. This antifreeze must be disposed of properly by taking it to a repair shop for pick up. Next remove the fan guard followed by disconnecting all the belts. Some people remove the radiator to gain working room. before removing the radiator disconnect the lower hose and the upper hose to the engine. The transmission oil cooling lines are next. Now remove all the bolts holding the radiator in place. As you can see this is not a job for a novas. If you are not mechanically inclined this could be a nightmare of a job.

Got a 96 crown vic that runs but smoking white smoke from under the hood and it runs hot ....the resevoir is full so there is no leak there and i replaced the thermostat but it didnt work

you ether have a coolant leak or one of these are the problem thermastat,fan clutch,water pump,radiator, try this start car when it reachs normal temp open hood and pinch the top radiator hose if it is hot water is flowing thermastat is good now open radiator with a towel slowly while it is runing see if the water is moving if it is you water pump and radiator are good, now at some point in this time you should have heard the fan get loud if not your fan clutch is not work it mounts to the front of your water pump and is normal to go out because they lose about 250rpm a year which does not give them much of a life, dont forget to check your heater hoses they could be leaking

Stalling problems

Remove the raidator cap while running or watch the overflow tank for bubbles. If you see bubbles either way, most likely your cause of the overheating is a leaking head gasket. If you have a cooling system pressure tester, pump up the cooling system and see if it looses pressure, if it doesn't hold pressure, again bad head gasket.
