Water temperature sensor

Possibly cracked/broken temperature sensor unit. Normally located in front of radiator/AC condensor. You can usually see it with the hood open in front of the radiator area bolted to the upper rad support or the center support.

Wow, this is a long answer. Check youtube for video. It is not hard, just messy.

Could be, or the engine temperature sensor may have failed, making the vehicle think it's always cold.

i think it is refering to the engine temp sensor ,not a sensor actually located in the inside of the vehicle,on this model the coolant temp is controlled by the cylinder head sensor ,see attached shematic hope this helps

Hello, I was going to pass on this question but I have several solutions for you to try before buying this car.

The first idea is for you to have someone grab the water heater hoses after the heat has been set and the engine is at normal operating temperature. The idea here is that there is a water flow valve that puts the hot water through the heater unit and when both heater hoses are hot, it indicates the water is flowing and something else is wrong. You check that by handling those 2 water hoses around the heater coil.(It disappears in the Firewall)

Next, the fancy Digital dash that most Lincolns use is capable of self-diagnosis. If you can get a free check of this Digital dash unit at a Dealer, it will tell you what part is broken. All that is needed to do this is a sequence of button pushing on the correct keys in a certain order. It takes less than 5 minutes and can be done in a Parking lot or Writeup bay.

These Codes are in a different group of codes than those on the rest of the car. So the person would need to know what the self-diagnostic report means. It is something that can be done as a courtesy.

check your vacuum lines there is also a part called a throttle position sensor. check that too

You have a separate sensor for the fan. But check for blown fuse or bad relay first. Both should be identified in the owners manual

For 1997 Lincoln Continental 4.6L SFI DOHC 8cyl the Coolant Temperature Sensor is located: Under hood, passenger side, front upper engine area, mounted in intake manifold near water outlet.

Hope this helps (remember to rate and comment this).
