Temperature Sensor And Oil Sensor
Posted 20 July 2012 - 01:06 PM
I've done temperature sensors on Capris before and it was quite easy, whip it out and put a new one back in and just 'cope' if a little coolant comes out. But the Mini one is larger, can I still do this?
The oil sender I've never done before. As above, can I just take it out and swap it or will it make an awful mess?

When doing the oil pressure switch, you should only lose a tiny drop, as long as the engine isn't running at the time !!

Thanks for the advice. I was just worried doing it with liquid pouring out might stop it being watertight but I'm sure the thread is long enough.

The standard Mini oil pressure gauge is mechanical, not electric so there is no sending unit. There is an oil pressure switch on some cars. They do fail but not often. What symptoms that make you want to replace it?
The temperature sending unit will loose some coolant but as you said, just top-up afterwards and you will be fine. Is that sending unit known to be bad or do you just suspect it? What symptoms make you want to replace it?
EDIT: The Mini temp sending unit will also be different than what you may be used to in that it seals/seats with a tapered profile towards the bottom of the part. It doesn't seal on the threads as such. However, a wrap of Teflon (PTFE) tape on the threads won't hurt if you are worried about leaks.

For the temperature sensor, replacement may indeed help but if it doesn't, be sure to check the wire from it to the gauge. Also keep your eye on the fuel gauge. If it is also acting up in the same manner, the problem will be with the voltage stabilizer or the supply to the stabilizer.
