Hi,
Having a problem with the extra oil pump fitted to my 91 T25 turbo diesel water cooled. It comes on intermittently even when the van has not been used for a few days. As it is only designed to cool the oil after the engine has been turned off, does it really need to be there? If it should be replaced, is it a faulty pump or a faulty thermostat somewhere else?
Hope someone can help. Think this is what ruined my battery over the winter!!

I've never heard of this extra pump, but I know little of Diesels. However, it has got to be a thermostat issue as that is what will be supplying power to the pump. If the stat says "stay off" then, as far as I can guess, there is unlikely to be any other source of 12V able to reach the pump.

Could it be the extra water pump? I believe that the temp sender for these can cause issues with going on and off

Thanks for the info. You could be right. The justkampers manual calls it an oil pump but they have a few other mistakes so will check. Hopefully a new thermo will be less than a new pump.
