Question about 1986 Lincoln Town Car

2 Answers

I just had the sensor replaced, changed to a heavier oil, replaced the thermostat, and flushed the coolant picked up my car and the oil light comes on after the car warms up when I slow down, Could I have gotten a bad sensor or does this sound like an oil pump? I don't want to keep fixing stuff by their guessing.

    Took it back to shop for 4th time. They removed sensor and checked oil pressure-- cold it was 70 psi. Hot is 32 psi. Now they say the oil pump is weak and it costs $1051 to replace. Asked why they didn't check before given issues and got excuses. What do you think?

Whose guessing. Have a repair shop check your oil pressure with a Mechanical Oil Pressure Gauge, and that will tell you what to do. If its OK, the oil switch is bad, if the oil pressure is low, the eng may be sluged up, or oil pump or worse problems. If its below 10PSI at idle, its most likely toast.

It could be a bad sensor, but since your going to have to remove the sensor to replace it. Attach a oil pressure gauge to where the sensor would be and see what the true pressure is. Good luck and hope it's the sensor and note that the oil sensor should have been installed without any Teflon tape. The sensor is a tapered fit and Teflon would give it a faults reading, due to bad ground to the engine.

Have the codes read. I haven't worked on any thing to date that reduce power because of the coolant system or the oil. I have done some that will kill the engine because of both, but not reduced power. This could be from an engine hard part, sensor or wiring. Most times it's caused from a transmission problem.

Warning light


To tell you something like: Engine low on water, low on oil, thermostat stuck partway or closed? Oxygen sensor or catalytic converter clogged, coolant temperature sensor terminals dirty or rusty, or sensor defective? Gas cap not screwed on correctly? Some vehicles may be telling you to change oil, and/ or check filters for scheduled service? Just to pick a few reasons out of the air.

If the coolant and thermostat is over 2 year old then it is time to replace thermostat and coolant flush to get all the deposit out.

Flush and fill the coolant reserve tank slowly. I recommend put the car on an oil change ramp to prevent air pocket.

The coolant light is on in my 95 camaro. History: .July 2006 i flushed out the rad and then took it off the road aug 2006....due to financial constraints, not mechanical issues........Its in great...


Hello: If the light is for low coolant level and the radiator/overflow tank are full it will not hurt to drive it. The thermostat has nothing to do with the coolant level switch. The level switch will be in either the overflow tank or the radiator tank.

The water tank boils a lot when the car is driven for about 15 to 20 minutes and it begins to spill out. this prevents the cars from running smoothly and easily. what should be done to solve this problem?


First check to make sure you have no oil reidue in your cooling system. What you describe is a common symptom of a blown head gasket or other combustion chamber leak. Also check your oil and make sure it doesn't have a milky appearance. If both of those check out, run the car with the radiator cap off and let it get up to normal operating temperature. You should see the coolant flowing through the radiator. If you don't see the flow at normal operating temperature, suspect the thermostat. When the car reaches normal operating temperature, the fan should also cycle on and off. If it doesn't check your fuses and relays to make sure they're OK. If they're good, try applying a seperate 12V source to the fan. If it powers up then suspect the fan's thermostatic control. Good luck.

Low coolant light stays on. Changed sensor. Still comes on. Tech says oil leaking into coolant contaminating sensor. Says this is a common problem with this car. Is this a head gasket problem, and will...


I had a similar problem. Replaced head gasket, but low coolant light stayed on. My problem was air in the system. A flush and fill kit may work, however, I had a local shop do a "flush and fill" and the problem remained. What I did... With vehicle running, and radiator cap off, bring engine to operating temperature. Increase rpms slightly above idle until coolant can be seen moving in radiator (thermostat open). Add small amounts of coolant, keeping the radiator level just below overflow hole in cap area. In my case, after about 15 minutes at slightly above idle rpms, a large pocket of air escaped. I topped off radiator, installed cap, and let engine cool. Problem has not returned in last six months. *Note coolant is VERY HOT, and if rpms fluctuate, coolant will expel quickly from radiator. Also, when the air pocket escaped, coolant also sprays out. Use caution to avoid being burned.

Flushing the radiator, replacing the radiator cap, adding new coolant, replacing the sensors and a new thermostat solved the problem. Probably didn't need to do all of these things - but since we just purchased the truck, and given the fact that is probably hadn't been done in a while, we chose to do all of these things (which really didn't cost a whole lot), it's running like a charm now.
