Yea, cap or do without the oil cooler. Do you tow with your Tahoe?
Thank you for the adviceUnless your engine idles for extended lengths of time, or works or plays HARD,
there's no need for any engine cooling provisions ...
Probably just cap it off. Engine oil coolers were more common on the 2500/3500 trucks and 2500 SUVs as towing packages. I guess some 1500s also had them? They also tend to leak from several places (at the engine block and at the crimps) over the years and you wind up with a huge mess if you don't correct the issue early.
In your case, you have to replace the radiator with the one that had that option, and buy the cooler lines (I'm assuming those lines are still available for that vehicle(?) IDK). Capping is cheaper/easier.
