[Roadsters] Radiator cap question

[Pat Horne]

Michael,

That cap can be repaired if the metal is in good shape. That cap has no 
pressure rating, just a flat cap with a sheet of rubber in it to seal 
off the tower. Find a sheet of thick rubber gasket material and cut a 
piece to fit. I did this to my cap quite a few years ago and it hasn't 
leaked since. If you can't find sheet gasket material, check around for 
a radiator cap or gas cap that you can get a large enough piece of 
material out of to make the seal. It doesn't have to cover the whole 
cap, just around the edge where it seals to the neck.

Also, look closely at the sealing surface on the neck. They get rough, 
which causes damage to the gasket, as well as allows small spaces for 
leakage. If it is rough, take the neck off and carefully rub it on a 
piece of fine sand paper on a flat surface. Don't go overboard, just 
enough to get a good seal.

Good luck.
Peace,
Pat
