I put some radiator flush stuff in about a week ago. Today I removed the overflow tank and cleaned it out. I pulled the thermostat out and upper and lower hoses and I flushed the block and the radiator from the top. It looked pretty good inside. I looked at it from the lower hose and it had a little buildup on the ends. I put everything back together without the thermostat and filled it up with water from the hose. I want to flush it out one more time and then I will put my new hoses on. I was having temps up to 235 and it wasn’t dropping so I thought maybe a flush wouldn’t hurt. Fluid looked clean and green. I have a new thermostat to go back in when I get done with it. I replaced the fan switch sensor on the thermostat housing a few days ago. I also put a piece of 1/2” x 3/4” foam between the transmission cooler and radiator. I took the cooler bolts out and cleaned the leaves out and I lowered it down onto the foam. I have a tree that I hate and it drops leaves and little round seeds and the leaves get into the radiator and they curl up in it. I will be able to vacuum or blow it off the top of the radiator now.
