  1. #1

    '69t front pull cooler fitting leak

    Oil leak from this fitting. Is this an easy fix? Any leads on where to find this section of line and fitting?

    The tricky part may be getting the lines off, but once that is done those are just factory lines, or look up Brad Davis on this site, send him the lines and he'll make new ones. And do both.

    Stock S hoses won't work. By my observation that's an '84 Euro cooler and later lines on a long hood. (With no visible means of support from an upper bracket for the cooler. At least that I can see.)
    Buy stock 76-89 front hoses from just about anywhere. Super inexpensive.

    Is that oil cooler connected to anything?

    Thanks for the help guys. Turned out to be a relatively easy (albeit messy) project. Yes, there is a strong bracket on the bottom with two rubber bushings. At some point, I'll fab a second bracket for the mount on the top/front (but it's relatively sturdy as is)

    Quick question: after assembly, I started the car on the lift and tried to bring it up to temp for the oil to run to the cooler... is there a thermostat somewhere that a can jump to test everything out without having to actually get the oil temp high enough to trigger the thermostat?

    Not that I know off Glen....

    I believe the standard thermostats opens at about 190, just a few ticks above running temp, it not too hard to get it there... When both hard lines are hot it's open....

    Hope this helps,

    As per Frank's observation. It looks like the top support tab on the cooler is not secured to the back of the headlight bucket as it should be. the resulting movement and vibration might be the source of your fitting failure/leak. Generic lines, but not so cheap any more.

    Any tips (or photos) for fabbing a bracket for that location behind the headlight bucket? Also, do you recommend high temp thread sealant for the fitting connections?
