I've recently been working on improving the cooling on my M20, starting with a coolant flush and putting some good ol' BMW blue in. However, I have some other questions.
My coolant level sensor (on the expansion tank, yes?) keeps giving me problems, the check light comes on only when the engine is warm even when the level is fine. Would this be a reliable replacement? It's not OEM, which is worrisome.
Next is the fan clutch, it has gone bad and needs replaced. OEM is once again a bit spendy, but this is affordable, will it work nearly as well? Also, are any specific tools necessary to change it?
The aux fan is another concern, my mechanic had unplugged it at some point and said it wasn't really necessary, but after removing it and testing it I figure I might as well use it, though I'd like to know why it was unplugged...Only problem, I don't want to put the AC condenser back. how can I mount it to the car? I know euro brackets for this exist, but they're expensive and mostly unavailable. Would something like these work? I don't need an elegant solution, just something sturdy for what is my DD.
My final question, and it's of little concern, is how I can test my oil cooler. Though it's not leaking, it never warms up like I'd think it should.
Thanks for the help, forgive me for asking so many questions.
