I just bought a Harley oil cooler and the instruction say to glue the external cover on with a $60 sealer. What have you all successfully used in place of that recommended sealer. The Harley Dealer recommended JB weld, But JB weld is good stuff but I really don't feel comfortable using it to glue on the cover. I think it needs something more flexible.

 

Glue the cover on? Which HD oil cooler do you have?

If that is the case, you can either use an adhesive or a tape.

I think it was rtv, I have it sitting on a shelf, dumped it for the ultracool 2.0.

 

I used permatex high temperature RTV. Only $8.50 So so good.
