I noticed my oil cooler lines are leaking at the fittings, how hard of a fix is this?

You can do it yourself, have the line made or buy them from a vendor.Matt Bachand;1534931; said:

Dorman is making a few different oil cooler lines (Dorman has been in the industry for years with wheel studs, nuts, and other misc. pieces)
I have yet to see a quality issue with the hose assemblies..

Just replaced lower from oil filter adapter to rad. and I believe it was Doorman (sure wasn't from the stealership). Old one wore through, watch when replacing so that when done lines are secured FAR AWAY from anything. If I never say anything more about that line, it means it doesn't leak or God forbid, fails suddenly. That's cause I'll forget about it till then. One more item, put rubber isolators on where the lines are bolted down, my first set failed cause the bolt loosened just enough to cause vibrations to wear through the metal portion of the lines and I lost a lot of oil FAST. Do not try to replace the rad. fitting (part that screws into rad.), it most likely will break.

If Dorman is engineered like GM built them pass on them, build or buy a set that uses threaded mechanical fittings & stainless hose, site sponsors Kennedy & Lubrication Specialist sell replacement kits, OEM design is poor at best and will probably leak again, at worst retaining clips at block will rot and lines blow under load, 40-0 psi oil pressure ain't a favorable situation to be in.
here is what I did if this helps.
I am still getting my info together for everyone to see.

I haven't had to fool with my oil cooler lines yet.
However, I had an '80 camaro that I put dropped a 350 in (out of my old '72 blazer. I bought an oil cooler from JC Whitney. IIRC, it came with the oil filter adapter, if not it was no more than $20. The only thing that it didn't come with was the 5/8" rubber oil lines. I finally found some at a marine parts store. All in, installing the cooler cost me under $100. Granted, braided stainless is a nicer job, but I would expect 10 years of service out of the rubber lines.
Now, since our trucks already have the oil cooler and the oil filter adaptors, the only items needed are the hose barb fittings, clamps and hoses. Finding the right fittings may be the hardest part of this repair.

I just received a pir of Doorman lines for Discount GMC parts and one didn't fit. Their C313110 (Doorman # 635-114) fits. It's titled upper hose. the C313119 (doorman # Unknown) didn't fit. If you look close at the picture you can see that the end that fits the engine is straight and I needed a 90deg end on it for my 2wd 96. These are the 1/2" lines not the later larger ones. I wasn't able to find a hose that would fit. fortunately the one that fit was the one that was leaking.
If you go to return anything to them you are talking to unknown folks it the other world but they get returned to Auto Parts Warehouse in CA. They won't pay the return postage either.

Take your old hoses off, take the fittings out of the block, and take all that plus your oil cooler to your local hydraulic hose maker, and get set up for about $100.oo for braided stainless

This is one reason why I replaced the cooler when I replaced the lines.irelandd;1550288; said:
You either have to use the old fittings somehow, or get a new cooler.
You can't use threaded fittings in the cooler.
I'm about ready to give up and just spend the money for Lubrication specialist lines.
I am almost done with my re-man engine and now this stumbling block.
Napa: "We dont carry oil lines". "Did you say transmission cooler?"
Advance Auto: We carry oil lines but I don't know what fittings are on the end. We can sell you a B&M cooler for $130 but we don't know what fittings or sizes come with it.
Auto Zone: Same as Advance Auto.
Hydraulic line shop: "We could make your SS lines for $130 without the fittings but the fitting in the oil cooler is not something we carry. Did you try Napa?"
My engine is from a 97 so larger ports on the side of the engine. My cooler is original 95 so smaller o-ring lines.
Arhggggg.

Give Central Diesel or Goodall Rubber Co. a call they are in the book under Hose Couplings and fittings. If they can't make them for you they can probably tell you who can make them.
Another place is Sutton-Clarke Supply, I was referred to them for a fuel line that was using an unusual AN fitting.
All in Richmond yellow pages.

That is what they told me. I said make me the lines and I told them it there any fitting you might have that might work. They gave me some ideas and I took oneof there fittings that has a rubber O ring to seal it up and it worked great.
The factory setup uses a brake line tool to make the right flange to seal into it. Hyrodric shops has the fittings that can go into there but do not seal like the original. That is why I used the fitting with the rubber O ring to seal it.

Did not get mine off yet but what's the chance of a welding shop putting something on it for a fitting?
