MPI vs Metro rad, Secondary Rad
Turbo Mini Forums

Hey guys, my friend has a problem with his cooper s overheating now that the weather's warmed up a bit, so was wondering if the Metro radiator is better than the MPI one? And if not, what would be the best replacement.
Also has anyone run a secondary rad? If so what benefits does it give, how simple is it and can it be done in-situ or do you need the head off?
Sorry if I'm asking numpty questions, did use the search function but came up blank.

There is no sense crying over every mistake- you just keep on trying til you run out of cake.

The MPI rad is supposed to be a good bit of kit. If the cars overheating i'd suggest looking for the reason/s why, rather than just sticking a bigger rad on.
I seem to remember somebody running a 2L Vauxhall Mini on a MPI rad with no probs.

Yeah, thought had occurred to me. Gonna be checking the thermo this weekend, wouldn't have thought it's ignition related 'cause it's ecu controlled. Seems to be flowing water ok atm. Of course there's probably something I've missed!

MPi rad should be good for 150+bhp no problem.

Is the fan working? That is a common MPi problem and normally due to the connector / wiring from the brown temp sender on the side of the head.

Has the water pump impellar come loose? Not unheard of on MPi's either.

How fast and how expensive ...... the same question...
