My 92 K1500 has a engine oil cooler set up and the hoses are leaking real bad,wondering if I can put plugs in where hoses go and run it that way without hurting anything. I dont use this truck very hard anymore.Any one done this before?

Thanks

Should be able to plug the oil filter adapter. That is how they are when they didn't have a cooler from the factory.

I had to put new hoses on mine. I didn't think they were terribly expensive. As I recall you have to know which radiator you have to get the right hose.

Steve@Advance · Feb 14, 2017

I've never tried plugging them, but would want to do some research first.

It's possible plugging them could stop or restrict the oil flow, not good!

Thinking those lines come off an adapter above the oil filter. Possibly the adapter should be removed, or loop the hose instead of plugging.

If you have 2wd you can eliminate all of that and go with pre 86 filter and filter mount-bypass. if you have 4x4 you will need that newer filter adapter. when I used to remove coolers I would buy adapter for a non cooler aplication. but there is cooler bypass in adapter in case cooler plugs up.It would be possible to plug them but was never comfortable doing so. I would buy new lines .Paul

Sure, you can toss the lines and plug the holes. There's no law against doing such stupid stuff.

Bottom line is, if you do that, oil flow will be through the oil cooler bypass valve that opens at a few PSI when the oil's cold and doesn't want to go through the cooler, which will work, but sure doesn't do anything good, and will add to oil heating in warm weather.

I would replace the lines, they aren't terribly high-priced.

If you are bound and determined not to, do some research... some GM oil filter adapters have an internal plug that can be removed to allow easy oil flow if removing the external cooler, or swap to a filter head without provisions for oil cooler lines.

You can buy both lines for less than $40 with shipping from Rockauto. Dorman part # 625141 and 625142. Plugging the lines is a really stupid idea.

Didn't all K1500 which were 4x4 came with oil coolers. I have yet seen one that didn't have an oil cooler.

Sprint 6 · Feb 15, 2017

Oil cooler was an option. I have a customer with a '94 K1500 that did not come with an oil cooler.

I love it when people targeting stuff is stupid. A 454 yes need an oil cooler. A 350 was made for three decades without one.

mozark · Feb 15, 2017

My '95 K1500 4X4 has no oil cooler.

Mike M · Feb 15, 2017

All the older stuff never had those coolers and were fine.
I'd remove the oil filter base adapter and install the one made for without the cooler to prevent any pressure or by-pass issues that might pop up.

buickanddeere · Feb 15, 2017

Vehicles were equipped with oil coolers for a reason. Some select models did not have sufficient conventional glycol cooling capacity due to airflow of the chassis , rad or fan size. Thus an oil cooler was added .

I have a 97 GMC K 1500 that came from factory with engine and tranny oil coolers and was not an option it was standard equipment.But it also came with 3/4 ton frame and springs.

MN Scott · Feb 15, 2017

96 and newer all models had the coolers. 95 and older only trucks with heavy duty emissions had the engine oil coolers. My 94 K3500 with the 350 has the cooler lines.

4wdtom · Feb 15, 2017

When removing something like that from the oil system you would want to make sure that the extra volume isn't overloading some other part of the system. It may be made to flow so much oil and reducing that flow may overload a a relief valve somewhere. In cool weather you may not need the cooler. In warm weather you may. I would want a oil temp. gauge if I was going to mess with the cooling system. If you can get the replacement hoses reasonable I would just take care of it that way.

ditchwitch · Feb 15, 2017

it had the tow package on it probably because of the external cooler. It might have a 400 turbo trans also instead of the 350 turbo trans

Super-H-Mike · Feb 15, 2017

I have done it, I just used the oil filter adapter from an older 350 with no oil cooler . I think I had to use a shorty oil filter to clear the front drive shaft, but no other problems .

JDEM · Feb 15, 2017

My 1982 Chevy with a 379 has an oil-cooler and lines (that rotted out). As I recall, they cannot be blocked without messing up the lube system.

Agreed, B & D.

The three primary cost considerations of automotive design are: 1.) cost, 2.) cost, and 3.) cost.

Manufacturers only add non needed equipment when dictated by government.

FYI-

I just did this on the 2000 with the six liter engine. Those are a good bit pricier. It cost me $187 at the Chevy dealer to get those two lines (which merge into one mounting block). I learned several new bad words putting them on. A 2500 4x4 doesn't have much room for those. I even had the water pump and steering pump off and it was still nearly impossible.. I'm still kind of bitter about the whole experience.
