Oil cooler lines.

On my trail truck I have the cooler fittings on the side of the block looped together with a piece of hose, nothing more. I intend to put a cooler on it eventually but I am cheap and lazy and a cheap and easy solution has not presented itself yet. Doesnt seem to hurt anything but then again my truck is a piece of **** so take that as you will.
 
I thought of doing that..

I suggested to that guy who just plugs his coolers off,that looping a hose mght be a better idea than just plugging it off--but he said naaa......:dunno: ..guess it doesn't matter??...(guess if no oil comes out,it dont need to go back eh?):confused:

Wonder if you could use copper tubing,wound like a coil or pigs tail??--that would likely add SOME cooling,yet eliminate the crappy ,expensive OEM lines ..:thinking:
 
Well on a CUCV that I got as a parts truck many years ago it did have just straight up plugs in the fittings, but I am not familiar with the oil circulation path inside the block so I figured ALL of the oil might go through the cooler fittings, you know like there's no bypass. I figured if that was the case and I did just plug it it would totaly destroy the engine and I havent had any trouble from my looped hose yet. I do intend to put a cooler on it some day though.

The oil flows from the oil pump to the cooler, then through the filter and on to the rest of the motor. There is an "oil cooler bypass valve" that opens at 9-11psi to ensure oil will still flow if there is a blockage in the oil cooler.
 
I just found out from a guy I know that is a GM tech that the fittings on the ends of the lines are 'proprietary GM' stuff that doesn't cross over to another application. On the good side he says he may be able to get me a new line for a bunch cheaper than i could. We'll see...I hope so.

I know on my 6.5, the fittings that snap into the block adapters are one off-GM stuff, but the adapters that screw into the block are nothing more than 3/8 NPT threads. I now run a set of stainless steel braided lines, to get rid of the factory GM crap lines with just some 90* adapters out of the block.
 
The 6.5's dont have the oil cooler in the radiator, they only have an external one. Depending on how much the lines for the 6.2 cost, it could be cheaper to go that route and have some quality lines made up. The setup i have cost significantly less than factory replacement lines, and i got a new oil cooler out of the deal to boot.
 
I have an external cooler off a later model 6.5 equiped truck but it uses the same fitting as the built in ones on the radiator, which I believe is what we are having trouble figuring out. Right?
 
I wonder if one of those stacked plate tranny coolers would work?
