Radiator question

[mballn]

Hello!!!

recently my M50 overheated on me, last night I had the chance to dig into it and found out that the water pump failed. im thinking about doing a full coolant overhaul. now I was running a 318 radiator and not sure if I should get a new 318 radiator (with integrated expansion tank) or get a 325 radiator?
should I keep the mechanical fan or get an electrical fan? Any advices on a practical, reliable route?

Thanks

The late 318 radiator and electric fan have been serving me very well. Stupid simple to bleed and looks cleaner IMO.

when i do my swap i'll be using the new 318 radiator with integrated expansion tank, its a much cleaner look.

or i'll be getting an aftermarket one with metal end caps.

Get a late M20 radiator and expansion tank and be done. So much more efficient.

mishimoto e36 rad from amazon, my fans have come on once when I let it idle for ~20 mins in my garage checking for coolant leaks
