I had a overheating problem which caused the head gasket to go. i replaced that and now its over heating
again . so i removed rad to check it was ok and i have discovered loads of bent fins. i have sorted those but
i have a area the size of a tennis ball where all the fins have completely crushed in and will need to be removed.
The rad does not leak but how much damage to fins is exceptable ? please help

takes me back to my days of P38 mate, used to fill my car rads with it to stop em leaking, worked for years, i wouldn't advise it tho.Are you sure the rad is not blocked?

thanks for the reply. yeah rad seams ok apart from all the missing fins. looks like someone has blasted them through with a
jet washer. holds pressure fine but just trying to work out over heating problem and this id the first problem i have
found so far. well that and a gunked up rad cap.

I would guess you have a gumbd up system

A few/lot of cooling fins bent over wouldnt make that big a difference imho

Flush the system a few times with the proper cleaner

Just a thought maybe your thermostat is u s

CHEERS RICHR. I was going to do the thermostat next. then check the water pump. any other suggestions ?

Do one thing at a time then you know what the problem was

I would do a couple of flushes first

Think i may have found my problem. rad cap top seal has gone. i will order one later. thanks for replys guys
