Oil Cooler Lines

Hello GMCers,
I was wondering if anyone has a source for replacement steel lines
that run from the oil filter adapter to the flex lines (which run to the
radiator). I have new flex lines but the steel 1/2" tubing is corroded
heavily. I was going to have them locally manufactured but the
hydraulic shops I have visited can't do the necessary double flares.
Surely somebody out there stocks these as originally used.

Thanks, Phil Swanson

Phil,
Forget the steel lines. Have them made of flex hose all the way.
Strap them to the frame with large tie-raps. The junction of
the steel lines to flex lines is a potential leak.

Phil,

Check with J.R. Slaten - I think he can do those for you.

I just removed a set of hoses that were installed by the PO this way on my
coach, and what I found scared me to death, and I promptly went back to steel.

The oil cooler hoses run VERY close to the exhause manifolds, and with rubber
in that location, I found that mine were burned through about 3 layers of the
host and very close to catastrophic failure (read: Oil sprayed on the manifold,
which would probably result in a fire). GMC used steel here for good reason,
and I wholly agree with and support that reason. I hence STRONGLY urge others
to stick with steel for safety reasons.

RE the leak, this is no more a potential leak than the fitting to the adapter
or to the cooler. Granted, there is one more connection, but it is not like
flared fitting have a high failure rate . . .

Allow me to put in a second plug for the stainless lines from JR - I have a
set and they fit perfectly. As an alternative, you could buy a flaring tool
and make your own. I had to do this to replace my transmission cooler lines -
I thought that I would just order them from Cinnabar and have a drop-in fit.
No way - they were about four inches too long and I had to cut and reflare,
which I found to be an almost trivial task IF you have the tool! Not sure
about stainless though - the soft steel is a lot easier to flare. All depends
what you want. On, BTW, you may want to check with a brake shop - pretty much
all brake lines are double-flared, and they should be able to knock out a
pair of lines for you (if they fab parts as a practice, that is . . . )
