Whilst testing my dashboard on Sunday, I left the engine running whilst I took some photo's.
The rad fan had switched on and was running fine.
Then suddenly, the coolant started to boil and was being ejected out the top of the radiator!
I have what I think is the M10 radiator with the BMW screw on radiator cap. I was able to tighten the cap about a quarter turn, so maybe it just wasn't tight enough? (Do you tighten this type of cap right down??)
But, like the rest of you, i'm starting to wonder if my radiator and fan are not up to the job. I bought a rad fan to fit on the front, so it's only about 9 or 10" daimeter.
I have vents in my side bonnets but none in the top bonnets.
It was only about 8 degrees ambient, so hardly a hot day! I only have the 2.0 litre engine. I'm also wondering if the water pump might be knackered?
I am thinking I might need a much bigger fan on the back of the rad?
Any ideas or suggestions of a bigger fan?
