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

    Looks like sandy gold! LOL

    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 LOL.

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