LOL
i had a feeling that would be you asking that
Mate just buy a new one for the sake of what they cost, definately worth while.
Don't hold it against me anyone please (

) but i bought one from halfords, and its amazing, car warms up well, but youve only got to drive along at 10mph or so and the temperature stays nice and cool, it does get up to temperature in traffic etc, and the fan works, but i can bypass the fan switch, and with the fan on for not very long at all i can bring the temperature right down to where it sits when driving.
LOVE IT

well pleased it doesnt overheat or get overly hot, NOT EVEN IN THE SUMMER
Best £4 something i ever spent
