My guess is that the Coolant Thermostat is malfunctioning. It should be replaced. It is found, usually, at the engine end of the top radiator hose. Two bolts hold in place. A new one us about 7 or 8 dollars. I rate it as an easy fix.
Good luck.
Where is the coolant temperature sensor located on a 2002 Nissan Sentra? my car s dashboard gauge shows my car is running hot the drops back down to normal any idea?[Improve]
Low Coolant or faulty gauge
The 1995 Lincoln Town Car coolant temperature gauge sensor can be found on the front of the engine. The coolant temperature sensor will be a few inches above the thermostat housing.
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
Bad gauge or defective coolant temperature sensor
engine coolant
These will be the coolant temperature gauge, oil pressure gauge, and battery voltage gauge.
Bad gauge and/or coolant temp sensor The coolant temp sensor doesn't control the gauge. There is a sensor in the head on the driver's side that controls the gauge. It is fairly easy to get to, probably one of the only things on a 4th gen. lol
water temperature. 180-220 degrees
20AWG is the norm.
Temperature.
To check the coolant level of a vehicle first see look for the overflow reservoir. There should be a coolant dipstick with a level gauge on it. Remove it from the reservoir to see the coolant level.
