Oil cooler flushing

[trbojo]

I've read on here not to use the stock oil cooler after engine failure because you can't get all the debris out. Does this apply to aftermarket radiators as well? I have a 4 core that's been on the car for years. I ran about a whole can of brake clean in both directions, intermittently spraying it, then compressed air. Was dirty at first, then clean with clear brake clean and air at the end. My engine guy also knocked out the bypass on the cooler adapter, said it would force oil from the cooler to go through the filter.

A lot of people will say no way, never reuse it. I have reused the cooler after trashing all the bearings on a car before and got away with it. Cleaned it with the same method you used. I am 50/50 on it nowadays...

NO way I would risk a dirty oil cooler flush on a new engine!!!

i appreciate the replies, but they don't answer my original question.....

I'm not telling you yes or no on this but here's what Iv'e done on half a dozen coolers threw the years and NEVER had any debri problem after this flush. I go to Napa and get me two cans of Trans Flush in the areosol can. It has a plastic tube with a screw on fitting on it. I cut the fitting off and then the tube will slide into you oil line (leave both oil lines hooked up to the rad.) I then take my garden hose and run it threw my basement window and hook it to my laundry sink. I put my good spray nozzle on the hose and then spray half the can of cleaner down one oil cooler hose and then with HOT water only (wear some heavy leather gloves as it's going to get HOT) and the nozzle on that heavy thin spray stick it to the end of the oil hose and flush, use the other half of can going the other way and go back and forth from one to the other until youv'e used up both cans of Trans. Flush. Shoot trans flush and then flush with water, shoot trans. flush and then flush with water back and forth on oil lines. Then air blow it out back and forth until dry. Iv'e never had a problem doing this.

Aftermarket or not, I wouldn't risk it.

Install an external cooler and be done with it. Cut that cooler open and you will find debris in it. I worked for Auto Kools systems for ten years and we replaced oil coolers all the time weather it was a trans cooler or a engine oil cooler. Every engine or trans I replaced when working for chevy recieved new coolers as well. One peice of old bearing material getting sent through the turbo is all it takes. Even if a radiator is 500 that is cheap insurance over a second engine rebuild. Aftermarket radiators and stock radiators have coolers that are pretty much the same thing. Im sure the factory gn coolers are long gone .

Any good radiator shop can install a new cooler. Just had one done and cost me less than $100 for the cooler and labor

how about what i said about the blockoff on the adapter?

Just eliminate the cooler. I never use one anymore. If you lived in Arizona then I would worry about it. Knocking out the bypass only forces oil around the cooler. All he did was remove the function of the cooler. Take the oil cooler adaptor off and screw the filter directly to the oil pump. Very little oil actually even makes it through the filter and/or cooler to begine with. The oil filter by-pass opens at about 10 psi anyway. So,......most of the oil never reaches the filter/cooler. Plug THAT by pass and run a dual remote filter set-up with filters that have built in by pass in them. The remote filters act as a cooler, too.
