    2019 paccar mx-13 I drained the coolant and put a new lower coolant pipe on and new coolant filter I refilled radiator and stop engine and low coolant lite comes on. I drove it and temp gauge fluctuates from 150 to near 200 and the oil temp is around 210. Any ideas whats going on?

    Like @Ruthless suggested, it sounds as if you have an air pocket.

    Like the others said. When it's coolish. Take off the cap and run the engine. Then add coolant as needed. You may have to burp it a couple of times.

    Like a baby it needs to be burped. Once you get the air out you'll be good
