coolant flush question

[Saltfishr]

Can anyone see a reason why I should not be able to use the EGR deaeration port hose to backflush (reverse flow) through the EGR cooler and the oil cooler and then out the drain? This would obviously be done when the engine is down and the system drained.

That's a awfully small hole for back flushing, I don't think you'll have enough psi and volume of water to make a difference. You might be better off removing the EGR cooler hose that goes to the oil cooler and clamping the flush hose to the oil cooler nipple.

I did this very thing before doing the restore flush, I will be doing a write up soon but here are some pics.

I'm hoping my egr delete will be here by next weekend. but should I flush before a delete. or after? I've had a DYI coolant filter on for about 32,000 miles I'm at 65,000 now and I have cut open ever filter and found nothing. but I still want to do a flush. now I know that this is a heated debate. but I live in the arm pit of the world as far as access to well stocked auto parts stores. I have found the Zerex G05 in a 50/50 mix but have not come a cross any of the concentrate. so In fever of dragging up some bad feelings about coolant could some of you list brand name and maybe were to get a good coolant fluid any mabe a link to a good step by step SOP on doing a flush
