The 1999 Cadillac normal coolant temperature gauge reading should be 180 degrees. A 195 degrees thermostat could be used, causing the temperature gauge to read 195.
This would indicate that the system is low on coolant when the gauge is hot. Not enough coolant to service the heater core.
Low Coolant or faulty gauge
If the temp gauge reads normal and the engine is not overheating, the thermostat is doing its job. The thermostat maintains the coolant temp by opening and closing allowing the coolant to flow or not to flow. When it is closed the coolant doesn't circulate.
any make after 1997 will be susceptible to electrical issues when engine is normal. i wish they would have left the computer stuff out of vehicles. gauge is most likely electrically impaired.
You may have a faulty coolant level sensor
Low on coolant or a sticky thermostat, replace it.
An inoperative temperature gauge will not alter how an engine runs, but the operator will not know if the water temperature has risen above normal without a properly working guage.
probably the coolant level sensor... Does the temprature gauge go up to hot then down to normal?
Because the temp gauge is not giving you the temperature of the water/steam in the radiator. You may have a bad head gasket or a cracked head causing the coolant to have that boiling effect.
You engine is generating more heat than can be removed by the cooling system. You should pull over, shut your engine and carefully (it will be very hot) remove the radiator cap to check the coolant level in your car. If you know where it is, you can check the coolant reservoir. If you are missing coolant, add enough to bring it to the correct level and monitor it for leaks. Otherwise you may have a problem with the cooling pump.
Probably low on coolant. Have coolant system checked for leaks.
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.
Sounds like it is low on coolant.
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
low coolant and/or radiator leak or maby a bad temp sensor low coolant and/or radiator leak or maby a bad temp sensor
Bad gauge or defective coolant temperature sensor
Either your coolant level is low, or you need a new thermostat because it is stickig, intermittently
Stand the bike upright and examine the coolant 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
If it's a VW, it's the water pump. For the temp gauge to read properly, it must have LIQUID coolant flowing over it. Steam will not provide a proper reading. If there's a coolant leak, it could produce a fluctuating reading. If you're losing coolant but not finding coolant puddling under your car, then the leak is not just a hose or line. It could be a manifold gasket or something. That ain't good. I recently ditched an old car because of that exact problem.
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]
A normal earring is 18 gauge. I'm not sure of the mm..
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.
