Temp. gauge don't move past half on 1996 VW Jetta


Sounds normal. If the gauge moved further over, it would indicate an overheating problem, wouldn't it? Check that engine is at normal operating temperature after it warms up. If it is running too cold, your thermostat might be stuck open.

If your radiator fans are not running at all than I would check over the wires your disconnected when rpolacing the temp sensor. Make sure they are fully connected. That would be the first thing I would check.

Check your coolant level and condition. If you havent' replaced the coolant in a while then change it. You can drain it from the bottom of the radiator plug. You may also want to change your oil and oil fiter.

I have a 2003 VW jetta tdi


You've lost engine coolant somewhere, and need to fill the engine back up with the VW special G12 coolant.

Then find the leak, which will be in one or more of the following places -
Water hoses to heater core, including any other coolant carrying hoses in the engine compartment
Radiator hoses
Plastic manifold bolted to side of engine which is known to leak (have replaced on an '01 VW Beetle, and an '02 Jetta, both members of our family in the past few years.).
Overflow reservoir cracked
Radiator leak.

Reply back what you find. If the engine got too hot, you may need to have the thermostat replaced.

Transmission fluid check on a vw jetta tdi


Never ever bring a jetta to a volkwagen dealer. They will bend you over and rape you.

All you have to do is remove the top plug with a hex wrench.
