Was about 20*C difference with identical conditions of M1 driving. I do very little idling, which would then give the same temp reading. But at the end of the day if the budget only allows for the tube and fin cooler then it is going to be better then nothing. All in all this is a rather constructive thread without people saying buy a manual.

Beeza: Does the hose go to a metal loop or does it have a cooler built into the radiator?

I would recommend getting an OEM cooler from the wreckers instead of new as they have smaller inlet/outlets that match the factory hose better so you don't have to deal with hose size changes. I have a 300zx cooler sitting at home doing nothing if you can't find any or want it. Isn't perfect condition but the majority of the fins are straight.

Make sure you mount it correctly with the inlet/outlet facing up or if you mount it on it's side have the outlet at the top. This is to prevent air from getting trapped in the cooler. I have seen them mounted upside down before. I'm not a fan of mounting to the radiator, but does make it a lot easier to install!

If you mount the cooler in front of the radiators then it will have 100% efficency, but will reduce the efficeny of the radiators. Behind the radiators and the efficiency will be reduced. It is up to you where you want it mounted, but I would go in front.
