96 GLX VR6 coolant indicator flashing

I have a 96 Jetta GLX VR6 Coolant indicator is flashing once it reaches about 190C. Plenty of coolant, not overheating that I can tell, radiator fan comes on. Light goes off once you turn off the motor. Any ideas?

Re: 96 GLX VR6 coolant indicator flashing

The light is an indicator warning light to inform you that the engine may be overheating.

Finding a professional mechanic and having him put a scanner on the car can help determine if the engine is overheating or if it is a temperature gauge system fault.

The engine should be checked for a bad head gasket. If the head gasket is faulty then it can pump cylinder compression into the cooling system causing an air pocket which can cause an overheating problem. It could also cause coolant loss in the engine while the coolant tank is full which could also cause an overheating condition.

It could also be as simple as a thermostat.

Overheating can cause the head to warp, burn valves and cause cylinder and piston damage.

Don't wait; get it diagnosed as soon as you can before any severe mechanical problems occur.
