Can a reverse flush save my oil cooler?

I just had my oil cooler and head gaskets replaced a few weeks ago. Unfortunately my system wasn't flushed before the replacement. I have been doing flushes every few days but just radiator flushes. I'm noticing my deltas getting larger. I'm up to about 10* now.

I'm wondering if I can do a reverse flush now and then install a new coolant filter can I save the oil cooler? I don't have another 1000.00 to drop on this truck right now. I just plunked down 4100.00 here recently. Any suggestions? Thanks

A 10* delta is nothing to worry about.
I havent heard of people having much luck with the reverse flush. The coolant filter is a good idea anytime and not too spendy up to a oil cooler. And its a do it yourself type a thing.
Just keep your eye on the temps,Id say for now your ok...but you shouldnt listen to me I voted for Romney!

I have the bypass in already but I'm thinking its probably clogged. When I first got the truck back deltas were around 5-7. Now they are getting higher. I just want to clear all the gunk out without clogging the cooler any worse. Thanks for the reply. I think you made a good decision!

I agree with WarChild. It probably won't make things worse, but don't get your hopes up.

But would you chance it with a BRAND NEW cooler? I think I'd do the sit and wait and see. After all he's only got 10* diffrence. Heck I can get that with the full BPD set up

I had good luck with a reverse flush. A year after doing oil cooler, my temps were back at 16 difference. Flushed with restore and restore plus. Then took the access cover off the oil cooler cover, and the block drain plug, poured some restore in there, let it set a few minutes, then used my pressure washer to spray into oil cooler. Did this 3 or 4 times. Max delta now is 8-9. Been this way since the flush 8 months ago. So it is worth a shot.
