Oil cooler lines leaking
They go from the back of the block to the radaitor on my 6.2. They're leaking where the rubber crimps onto the metal. Just wondering if there is a cheap fix for this?

Re: Oil cooler lines leaking
Cut off the crimp, replace the hose, and use hose clamps instead of the factory crimp.
Those connections have always been problematic... Posted via Mobile Device

Re: Oil cooler lines leaking
I've used clamps to repair a hole in the aluminum line, held fine.
I've also used regular clamps on air lines with 100+ psi. You could double clamp it with the clamps on opposite of each other. Heavy duty clamps are also available http://www.idealclamps.com/catalog/index.php?ID=3 The replacement cooler lines will leak again, it's just a matter of when. Seems to be an inherent design flaw or designed to fail for future parts sales... Posted via Mobile Device

Re: Oil cooler lines leaking
The auto parts store I go to was able to order them....they're a locally owned shop that's comparable to NAPA.
I used to work in reaction injection molding and dealt with a lot of hydraulic hoses....they all fail at the crimp over time.
