    Me again. Overheating 1991 Town Car. Trying to check fan clutch. Does have resistance, moves about 1/2 turn when pushed by hand, but jiggled the fan itself and it does have a small wobble. Anyone think I need the heater core flushed? Car gets hot quickly and boils and steams out the expansion overflow. ALSO, I DON'T UNDERSTAND WHY THE EXPANSION TANK (WHICH HAS A 'RADIATOR PRESSURE CAP' ON IT WHEN IT ALSO HAS AN OUTLET HOSE (FOR OVERLFOW??) THAT IS JUST OPEN TO AIR. What's the point of a pressure cap when there is an opening in the expansion tank anyway? Help!?

    Sounds like a bad radiator.

The year of the vehicle, rusty liquid, and overheating, says your radiator could use a replacement. If it was your water pump, you would have liquid coming out of the water pump itself.

    And, chances are flushing it out won't change anything. It's a old radiator, and has served it's purpose.

    You should be able to just back up the fan shroud and let it rest on the fan. Then you will need to remove the automatic transmission lines, the upper and lower hoses, and the retaining bolts.

So I can just replace ac compressor an bypass heater core an ac should work for 1991 Lincoln Town car


If the compressor is the problem A/C should work. But I work with idiots. I replace the compressor, expansion valve and dryer. And clean the system out. They replaced the compressor. then the expansion valve. then did it again after they clean the lines out, Then again, because the dryer held to much metal from the compressor going bad. And yes, you can bypass the heater core. But if the blend door actuator is bad, it won't be cold.

I have a 1992 Lincoln town car and i would like to know how do you remove the reservoir coolant tank from that car?


definitely something else causing the overheating. If the radiator has not been replaced in the last 5-10 years then the cores are probably blocked . Have a compression test done to check for head gasket and cracked head/s. If you have a viscous fan hub then replace it as it is no 1 problem if the overheating was occurring at lights , slow traffic, or pulling at slow speed up hills

I'm BAFFLED with a heater issue. Heat went off in my 1991 CRX SI with no apparent reason. Car is not overheating. Coolant in tank is full and it's clean. Top radiator hose is hot; bottom hose


Check the PUMP, there is apump that pumps the coolant from the radiator into the engine, if its broken you will have that problem.

The hose that goes from the manifold to the firewall busted and my car is overheating


that is the hose for the heater core you are likely overheating because you are low on coolant or have a air lock somewhere. if you don't need heat just clamp off both hoses to and from the heater core (firewall) until you can get it fixed but make sure you maintain the proper coolant level.

1991 overheating Towncar


If car heats up quickly and overheats , the problem is the thermostat. The thermostat stays closed and traps coolant in the engine untill it reaches about 185 degrees , than the thermostat opens and allows coolant to flow to the radiator where it is cooled by airflow. ( airflow while driving is usually sufficient ) while idling , or in slow trafic , the fan keeps air moving through the rad. The heater core is strictly for heat in the winter inside the car. The thermostat is the most likely cause of the problem , and even if it was good before , the overheat / boil situation likely cooked it anyways. I am assuming the water pump is still getting turned by a belt. No water circulation by pump would cause same symptom as bad thermostat. Overflow and expansion bottles are designed several different ways on different cars , but the theory is that as the engine heats up and the coolant expands , it goes to the tank. Later , as engine cools down after being shut off , coolant contracts. Radiator is replenished by coolant returning from expansion bottle.

1991 town car has no heat. What can be the problem?


He probably changes the heater core or checks to see if the heater core is circulating the coolant through. If the blower is not working he will check the Resistor and plug near the heater blower under the dash. Both are under the dash. have you replaced the thermostat ? If you do, after refilling with coolant, bleed the sysytem using the bleeding screw at the outlet of the thermostat until only coolant comes out.

93 lincoln town car coolant leak from rear of motor


Instead of removing the intake manifold and the the leaky manifold coolant hose, we simple place a 1" dia hose about 3" long with a **** down it so it can fit around the leaky coolant hose with two hose clamps and an agressive amount of "right stuff" silicone sealant and let stand for 24hrs which should fix the problem
