Well, I thought about this happening before I did the coolant flush. I put in the Restore lst week and drove home about 60 miles then dumped the cooling system and washed it with tap water from a hose.. Then I put in the Restore+ on Christmas Eve and ran it about 45 minutes.. I dumped the cooling system again and started flushing with distilled water. I would put in 3 gallons, drive it until it got over 180 degrees F then dump it and add 3 more gallons on distilled water. I did this about 7 times which would have the acid reduced to about 1/256 concentation. Yesterday I put 3.5 gallons of Rotella ELC in after dumping the cooling system the 7th time. I thought I heard a bearing squeal yesterday when I cranked the truck. Sure enough this morning when I got up to leave for a trip to my Smoky Mountain Cabin, there was red Rotella on the floor of my garage.


On further inspection, it was dripping off of the flywheel. Looks like the weephole sprung a leak. Called Napa and ordered a new not reman pump with a lifetime warranty. I also decided that I would pay the old now not a Chevy Dealership to put it on for me. Their labor was about $187. Pump is $125 or so. Got a new lower hose and drive belt as well.

Now Im at the cabin but my truck is 500 miles away. Thank God that it decided to puke before I got on the road. Its mighty cold out to be working on the side of the road.

I believe the Restore product cleaned it too much. Anyone else ever had this happen?
