Hello, my name is Ben and I think I have your solution. With all the work you have done and considering it isn't leaking or overheating, I believe your problem is the LOW COOLANT SENSOR itself or a short in the circuit. The sensor is located on the bottom of the coolant reservoir container which is mounted to the sidewall on the passenger side of the engine bay. Siphon the coolant our of the reservoir with a small pump and unbolt it from the sidewall. Turn it upside down and inspect the wiring going into the sensor. If you see no obvious bare spots, I would replace the sensor and put it all back together. Hope this helps, Ben.

I put a new thermostat in my 07 still running hot


water pump faulty, low on coolent, could be temp sensor faulty too if it reads hot all the time, even when you know its cold (like first thing in the morning) loose belt on waterpump, clogged coolent system, maybe it needs flushed.

Lost heat


Didn't mention that your car is overheating, so I will assume that your coolent is FULL and your waterpump and thermostat are working correctly, and that your car does get to normal operating temp (around 180-220 degrees F).. If the above is true, then disconnect the heater hoses from the engine and see if its clogged up with rust and/or corrosion. This spot is famous to get gummed up, restricting coolent flow through your heatercoil.

I replaced my waterpump and all gaskets in the housing. now the temp gauge on the DIC jumps high and low then dissappears and my service light came on...whats the deal?


once you have changed the water pump you refill the radiator to the neck and and run the car with the fan on and wait till the themostat opens.you will know this because the antifreeze level in the radiator will drop,let run and refill radiator and replace the cap.fill the overflow bottle to the full mark. on some models you have a bleeder on top of the engine to bleed the system. i would also pressure test the radiator cap or replace it as this is not exspensive but a vital part.

My engine light when on in my car yesterday and my friend has one of those things that can scan and tell you whats wrong it said my coolent temp below thermistat regulating temp and where where you pull...


Hi:
Your coolant temp sensor was not reading right, and is a sensor that adjusts your eng timing. I would keep an eye on your coolant level. That would be a bigger concern, figuring out if you have a leak. If the cold comes back, you need to change out the coolant temp sensor.

1996 Jetta appears to overheat but no coolent loss


the temp sensor is the trigger for the fans!!
the thermostat may be in upside down??
check new thermostat in a pot of water & heat it up watch that it opens up when it heats up should be at aroun 96 degrees F
otherwise the radiator may need a good clean out or a recore!
there my be a blocked water gallery so engine may need a flush aswell
