Something you don’t want to see in your oil cooler.

Looks like sandy gold!

Sand casting out of my oil cooler. Oil got hot (50 degrees at one point) but lucky I was running the good stuff. I made my own back flush kit to get it cleaned out with the help of a coolant gun and 110psi of air.

Ran a couple of days with CRC Salt terminator and straight water. Flushed it and back flushed the cooler again and got out a little more. But nothing like what the bucket has .

This time I’m trying out Amsoil heavy duty coolant. I had The extended life green with wix cool additive. We will see

Any update to this? How is the cooler holding up after the backflush? I did some pretty extensive backflushes this summer that didn't last, so I ended up doing a cooler replacement this fall.
