I'm having overheating issues with my m20. The cooling system has been refreshed (water pump, hoses, fan clutch, old radiator), but it is still overheating. The fan fails the newspaper test even though the clutch is a brand new Behr unit. Initially I thought I received a defective part, so I got another one and the result is the same. When the temperature gauge is up over half, the fan spins very weakly and I can stop it with a rolled up newspaper.
My thoughts
Not sure what is going on here.... Anyone have any ideas?
Thanks
My thoughts
- I was thinking the temperature gauge might be wrong, but it seems to be working to me. I keep an eye on the temperature if I'm not moving and switch on the heat and the A/C fan if its getting too warm, but that obviously shouldn't be necessary.
- The clutch isn't getting hot enough to engage for some reason? I'm unclear as to whether its conducted heat from the water pump hub that triggers it, the temperature of the air off of the radiator, or a combination of both?
