I did a search and found out a lot of info but I still have one question about removing my oil cooler. I know you have to block off the hose going from the waterpump and going to the radiator but is there anything I have to do with the holes that are on the oil filter plate(place where you screw the filter on)???

 

On cars that don't have an oil cooler, there is a hose (called a bypass hose-GM PART # 10197675) that goes directly from the radiator to the water pump.

You should totally remove the oil cooler from between the filter and block. You will need to get a couple bolts (GM PART # 3951644 ) to replace the studs that hold on the oil filter adapter as well as replace the adapter with the normal one (GM PART # 3952301) (I don't know what is different about the adapters, but I know they are different part numbers).

 

Thanks Shoe!!! I will look into that today.

 

Is it possible for me to leave the cooler portion on the block and just re-route the hoses where the coolant doesnt run through the cooler?

 

I guess it is possible to leave it that way, but removing it would be the "cleaner" thing to do, IMO. Maybe someone will reply that has actually done this.

 

Thanks again shoebox. I am actually not going to leave it this way, this is only temporary since I dont have a ride to the parts store.

 

Does anybody know what the difference is between the adaptors?

 

why are you taking off the oil cooler?

 

K another stupid question here......what cooler? Do only certain years have them?

 

Do a search, read, and then come back to this thread.

 

I've been...thanks for the help. Could took you less effort to answer. I just finished throwing my putting my motor together...dropping it and tranny in. Complete rebuild. I know mine doesn't have one.

 

I know this is a really old thread, but I'm planning to get some Kooks headers, which seem to require deletion of the oil cooler, and I have a question, or two.

In addition to the bypass line and bolts to replace the studs in the block, is it necessary to purchase the adapter referenced above? I've read quite a few threads about this, none of which seem to contain all the answers, and the only thing I've really seen in regards to an adapter is that it either isn't necessary, or that you can use the one on the oil cooler. So I'm just looking for some clarification. I'm assuming the oil filter won't just mount directly to the block.

Is anything else necessary when deleting the oil cooler?

I have the '94 style cooler, if that makes any difference.

Thanks and regards.

 

the threaded adapter bolts to block where oil cooler goes with short bolt where the studs were, in regards to different adapters possibly have one with a anti drain back and one with out? take the cooler off and see if the adaptor comes off if so by the bolts and bolt it in if not go to the junk yard and snag on of any # of sbc power plants

for those that dont know oil coolers are heat exchangers to keep oil temp from getting out of control, on the lt1 in this case we are refering to the oil filter mount the has to pipes running off the side of it to allow coolant from the water pump to pass through cooling the oil down to a more constant temp. this in conjuntion with the reverse flow cooling, heads first, and use of aluminum heads is what allows the lt1 to run 10.5 or 11 to 1 compression on pump gas for street use... all im getting at is why get rid of the oil cooler itll only hurt your performance...

 

Because some have had problems with them clogging, starving the engine of pressure and ruining the bearings.

 

The factory cooler is post filter and will allow trapped junk like carbon to reach the bearings. I took mine apart and was shocked at what I found. Once they are clogged they can restrict oil flow.

I am also a believer that the true reason for the "oil cooler" you are referring to is not to cool the oil at all, I think the purpose is to bring the oil up to operating temps quicker using the engine coolant to reduce emissions. The engine coolant will reach operating temp much faster than the oil. The only good way to cool the oil is to use an exchanger similar to a transmission cooler.

None of the LT1 Corvettes had an oil filter so from that standpoint they are not essential.

Here is a good thread to review:
