Open the reservoir tank and you will see two metal prongs. Clean the ends of the prongs with fine sandpaper so that a good electrical contact can be made between the prongs via the antifreeze fluid. Do this with the engine cold.

Obviously it's temperature gauge light. Check for coolant level first. Then check for coolant leak. If coolant is leaking out of your car, the lower coolant levels in your engine will cause it to overheat. If you have your heater on and it starts blowing hot air instead of cool, your engine is low on coolant. This will cause to flash a warning light on your car's dashboard.

It can be faulty coolant temperature sensor.Its not sensing exact coolant heat temperature so its overheating then required level.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.


Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

Where to add coolant for radiator on a 95 vw jetta?


Add Coolant to spherical reservoir at right rear of engine compartment as viewed from front. If it is low the coolant gauge flashing light will warn you of a low condition.

If this is a red flashing light beneath the temperature guage it means that you do not have enough coolant. Top up the large white ball shaped reservior at the right hand side of the engine compartment just behind the battery.
