I’m swapping in a used 350 in my k2500 and my truck didn’t have a oil cooler, the used engine does. Is there any issue that anyone knows of if I add lines to run to the radiator. Other than it will leak eventually...

Reason I’m doing this is because the engine that was in it spun a rod bearing, while pulling. In a k2500 I find it odd there was no engine oil cooler in it already.

My 2500 had and my 1500 has cooling lines. Order a new set of lines and new Dorman fittings. Also, get a new gasket kit from the dealer. Do not buy any aftermarket ones especially not the Dorman. They will leak.

So long you have the full adapter, use it.

Thanks, I’ll put them on, still wonder if some one deleted them. In my experience they all leak, even the OEM lines. I used to work at at gmc dealer and we replaced these lines under warranty when these trucks were new. Along with lower intake gaskets, wiper modules and heater hose connectors. But still my favorite style truck.

I'd skip it. GM trucks didn't have oil coolers that I'm aware of until the GMT-400. It's just asking for black rain on your driveway, if you ask me.

If you do, I'd get the GM lines. They may go bad, but they should last longer than the garbage Dormans unless the replacements aren't as good as the originals.

When I had a Dorman line, it lasted at most 2 years, and that wasn't two years and then it started leaking. That was too years from install until I got sick enough of it leaking that I bypassed the oil cooler.

My 99 K2500 has both a stand alone trans cooler and oil cooler in front of the radiator. It is a 454 with the 8600 GVWR however. Neither of mine leak and from what I can tell they're original. The only oil leak I have is right at the 90* adapter for the sideways oil filter RIGHT ABOVE MY FRONT DIFF! Curse you GM...

Your/Our adapter is nice in that it's only an o-ring. The small blocks have a flat gasket, too. I thought about simply finding the size and buying one from someplace McMaster Car out of a suitable material, but the OEM part wasn't very much. Changing the filter is a pain given we can't help but to dump oil everywhere.

That has to be the most annoying thing on that truck. Dumps oil every time right on the diff. I do need to replace that ring eventually. It leaves a drop every 2 days. Hardly concerning right now.

My oil hits a crossmember and my front universal joint.

Do the o-ring sooner rather than later, because your hydroboost, power-steering lines, and oil cooler lines won't be far behind. I had them all leaking very close to each other, so I'd fix one thing and discover I still had another leak. I pulled my oil cooler lines and plugged the ports, and changed the o-ring all at once... and then discovered the hydroboost was also leaking a few days later, at the most. Now my power steering lines are leaking...although, it's been some time between now.
