Hello, I have a 1990 VW Cabriolet with Digifant 2 electronic fuel injection. There are two different coolant temperature sensors on these cars. They are color coded. The blue coolant temp sensor is for the fuel injection system. The black coolant temp sensor is for the temperature gauge in the dashboard. They are located on a plastic manifold that is mounted to the cylinder head on the front of the engine about the center of left to right. This manifold is what the radiator hoses connect to. You will see two electrical connectors go to this. There are small C shaped clips that hold the sensor into the plastic manifold. To remove the sensor slide the plastic clip out of the side of the manifold, then pull the sensor straight up out of the manifold. There is a rubber o-ring that seals the sensor. Make sure a new o-ring is installed when put in the new sensor. I recommend you get a service manual for you car, and then you can see photos. I recommend a Bentley service manual (red color), or a Haynes service manual, or a Chiltons service manual. Good luck. Roger H. Best Regards,
how to locate engine coolant temperature sensor on a 1999 Cadillac De Ville Concurs
coolant temperature sensor are located where the coolant runs in the block near the thermostat housing normally the connector are on top of the sensor and the sensor itself screws in with a deep socket. The temperature sensor is usaully located where the coolant runs OUT of the engine close to thermostat housing.
where is the coolant temperature sensor locate
The coolant for a BMW x5 is placed into the coolant overflow tank on the left side of the engine compartment. It should be filled to the full mark when the engine is at operating temperature.
The Fiat Punto has a radiator which receives coolant in order to keep the temperature down. The diagram of this radiator can be found in the owner's manual.
To replace the thermostat on a 2002 Nissan Altima first drain out the coolant. Then proceed the to locate the thermostat housing which is by the engine compartment fuse box. Unbolt the housing and replace the thermostat.
To replace a thermostat on a 1992 Geo Storm first locate the its housing. Once found drain the coolant system and remove the housing from the engine. Replace the thermostat.
It is just below and behind on the area where the upper radiator hose attaches to the engine.
Rewiring a temperature is absolutely necessary when the wire has frayed since the temperature gauge in the car will not work with a burnt wire. Locate the frayed wires and cut them off. Measure the amount of new wiring needed and solder them on.
Heater Core or Hose has been compromised? Remove Cover for heater under dashboard if Coolant leaks out Heater core / hose has corroded through Replace Core or Hose. You may need to start car to operating temperature in order to locate leak Be especially careful under dash Once Coolant lines are pressurized ! you may see stream of coolant shooting out of hose or Core ! Eye Protection should be worn !
pop the hood, locate the coolant reservoir tank (has a cap with psi and temperature warnings) look on the side of the tank, and there will be a max and a min line. should be filled to min when the motor is cold. hope this helps.
To drain the coolant on a Mazda 626, locate the drain plug on the bottom of the radiator. Remove the plug and drain the coolant into a pan.
