Car: Astra MK3 1.4 mpi 1994
Was driving my car the other day and the temperature started heading towards the red (didnt quite hit it, but still higher than it should).
So I checked under the hood and the damn fan wasn't spinning.
I then rigged up some high tech equipment (a strip of wire) and placed them accross the coolant switch temp sensor cable (so it would trigger the fan) and the fan came on as you would expect.
Therefore I proceeded to buy a new switch and fitted it this morning, but its still not kicking in ?
Coolant levels are level and nothing is leaking, but why is that fan not kicking in?
1)The sensor on the engine is over reading, hence the other sensor that I replaced on the radiator isnt kicking in, because it isnt needed.
2) Coolant air lock somewhere?
Any other ideas or words of wisdom?
