Here's a question should it suck air in or blow out. Mine blows out!!

This thread below might help.

 

Mpi Cooling Fan Direction:-

"The MPi fan is a pusher unit that attaches on the front (grille) side of the radiator."

Thankyou my fan is in front of the rad and blows out, is this right or not please

It should blow through the radiator core.Steve..

I'll reverse the wiring then!!

We are talking radiator behind the front grille & not a Jap import with aircon & a side mounted rad? I'd also check it isn't a generic aftermarket replacement. The blades usually have an aerofoil profile, so won't be very efficient even if reversing polarity turns it from a sucker to a blower.

I was asked to look at an MPi  when a dead fan was replaced with a new one and it still overheated. The new fan came with red and black cable but it needed to be reversed.

Also need to make sure its a push, not a pull fan. The blades are optimised for their direction of travel.
