Mack dealer returned pump to rebuilder, they fixed it, rack actuator. Truck runs good now. Thanks for your help.

Does anyone know what happens when you mix red and green antifreeze together? Please advise. Thanks

yo you were right about the water, I heard someone else talk about putting ice on it. Thanks

The pump has just been rebuilt by Mack dealer. Checking connections at the computer module. Might need new module?

I have a 1998 ch612. Engine shuts down when at full operating temp. Blink code 5-4. Prior to this Mack dealer installed rebuilt injector pump and injectors. This proplem only occurs at full temp 180 degrees or so. Gray connector seems good and tight. It takes my truck a long time to warm up. I also replaced throttle position sensor.(thottle pedal) Is there another relay, if so where? Thanks
