Hi,

Does anyone know the real temp (not gauge temp) at which the thermal fan is meant to first kick in? Also, what the fan behaviour should be when shutting down.

I'll explain a little more the issue I'm having:

- For the first time, the car is showing above 90...

Any of the experts out there able to shed light on my question?...

Is there any merit in insulating the tubing/piping of the air intake, with say thermal exhaust wrap, or any other material?? The idea is to shield it from the upper engine bay heat..

My Stats: Mk4 Golf, GTI...
