Update adter coolant flush with Restore.

LiftedBlackHD · Feb 24, 2015

I flushed my cooling system with restore and restore plus. I used massive amounts of water and also back flushed. I then displaced the tap water with distilled by filling and draining with distilled about 18 gallons worth.

Prior to the flush my ECT was about 173 ( bad thermostat) i can get it up to 190 with cardboard in front of the radiator.

Prior to the flush EOT got as high as 224.

After the flush I'm getting the same readings for ECT however my EOT has dropped significantly. I'm getting 199-204 tops now.

I plan to drive it for a week or so while monitoring temps, to allow all the crud to accumulate in the old oil cooler. Then I will install a new one.

On my second drive the EOT crept up to 210. That is with the A/C on. Previous runs were without A/C.

That is my plan too.., flush... Then drive a few hundred miles... The delete the EGR and change oil cooler. I only have 6* difference.. But truck is out of Warrenty next month, so I want to protect head gaskets as much as possible.
