coolant question

[ksobiech282]

I bought some zerex extended life diesel ready coolant. Is it any good? It says its for cat ec 1. Also I just put in a new engine oil cooler and aftermarket radiator an long with a coolant kit. I didn't flush the engine before removing the old engine cooler. My truck has an egr delete as well. Now since everything is back together do I need to flush it still or just let the filter do its job? Also I drained ALL fluids from my truck before I start it again do I need fill them in a special way? Thanks in advance

I think a lot of people run that coolant. As for the flush, I personally wouldn't want to do the flush with a new oil cooler in there. It would just clog it up.

You can do a tap water flush till clear, then 24 gal of distilled water to get back to ph of 7. Then on the last drain, refill with 3.5 gal of fully formulated elc. I wouldn't do a chemical flush at this point. That coolant is fine.

Would the flush clog my oil cooler

Chemical, yes. Water, maybe, or maybe not.

If I didn't flush would the coolant filter pick up the garbage

Eventually it would, but another main reason for flushing, is so that you are not mixing different coolant types. That would not be good. If you are too nervous to do it, just match what coolant you had in there before, unless of course it wasn't ford. If it was green coolant/or really bad ford gold before, definetly flush and replace. Lack of coolant system maintenace is one of the first problems in a chain reaction of failures we have with these trucks. You are not alone. Deal with it now or later......

I don't mind taking the time I've been working on this thing for months. I'm just scared of possibly clogging the new oil cooler

And any "priming of fluid" tips

Put a couple quarts in the hpop resevoir. Refill the engine oil, at least a couple gallons through the filter housing allowing the oil to flow down the stand pipe.

Air in the coolant, can be purged best with the heater on, run up to temp, carefully realease the pressure, a few times to promote purging bubbles.

Cycle the key three or four times waiting for the fuel pump to shut off each time.

Put a small amount of fresh oil in the turbo feed port and rotate the turbine prior to installing the turbo feed line.
