alright, i've been digging for the the last 2.5 hours on this, to no avail. my key words turn up endless posts on here and google in general for the "flush" n' fill method for "power" stroke diesels, haha.

anways ,would having an oil change place do a coolant power flush save me any time servicing the coolant system? i've read through all the testemonials of people flushing up to 12 times before the sytem is clean, so in my head i'm thinking have an oil change place backflush my system, then come home and drain the radiator and both sides of the block and refill with distilled water and CAT approved EC-1 ELC coolant.

thoughts?

 

What are your delta's running at presently?

 

haven't checked them just yet. just bought the truck a few weeks ago, so not knowing it's maintenance history i just want a somewhat-clean slate. an oasis reports that the oil and EGR cooler were replaced at 99k (142k now).. which i would think in 99,000 miles most of the casting sand would have made its way through the system and into the old oil cooler before replacement.

 

Best bet would be to get a ScanGauge II and check everything you can with it. Then you can monitor everything down the road also.

 

Personally saving any time vrs. knowing it's done right doesn't wash with me. How much time and money does it take to fix screw ups?

 

Search for "oil cooler back flush". There is Garden hose n tap water version or Chemical \ water back flush with a transfer pump version. Other cooling system flushing method risks clogging the oil cooler even worse than it is.
