Overheating series 3

chubby5492 · Jun 15, 2006

Hi, I seem to have a problem with my 1982 series 3.
I have replaced the waterpump, hoses, thermostat, sender unit and added an electric fan, but the temp guage still hovers close to the red zone, and the fan cuts in even after short (two to three mile) journeys.
Any advice would be appreciated, as I am becoming reluctant to use it for fear of doing some serious damage! Thanks.

sounds like another rad blocked?
also poss HG problem?

maybe a garage could measure the temp more accurately with a meter?
(the water temp maybe ok? a long shot i know).

I'll go with Ormus's radiator theory.

Thanks, I've checked the rad and it is clear is it possible that the water pump is not pumping even though it is spinning/

have you tried to back flush the cooling system? its unlikey the pump will spin and not pump unless it was./is making weird noises.

i have seen a pump impellor shear its shaft before now, but it made a hell of a whinning noise.

does a hell of a whinning noise = weird noises?

Also check your temp guage isn't faulty, mine used to do a similar thing and turned out it was summat to do with the earth wire on the back of the guage.
