The radiator on my bike is showing it's age, there's no leaks or damage, it's just looking tired, if I paint it will it inhibit the cooling?

If painting doesn't cause problems does anyone have any recommendations for the type of paint to use?

Thanks.

 

Must be ESP cuz I was looking at mine on the 93 this am and was wondering the same
thing......... reckon it would have to be a bristle brush job Hawk with some vht motor
paint ............wot ya think ?

good cleaning required first though

 

I was thinking a black high temp paint, maybe Hammerite or something of that ilk, so long as it wont impede the cooling, though I don't see why it should so long as the vanes aren't blocked.

Yeah I think a brush job might be a good idea, unless you want to take it off the bike

 

I used Matt black engine enamel - never noticed any change in running temps afterwards.

 

Thanks for the replies guy's, more for the 'to do' list

 

Screw it , that's gonna be a next winter jobbie for me , suns shining
time to get riding

 

The garage roof was on my 'to do' list for over two years, I have a cavalier attitude to the list

 

Eastwood makes a high-temp paint called Radiator Black for automotive use. It's a high temp paint that's formulated a little thinner than normal paint to aid heat dissipation. I've used on my cars, but never a bike. Be sure to de-grease the radiator good before using
