cooling system high pressure and losing coolant
I have a 2002 Chevy Silverado with 6.6 Diesel. Have excess pressure in cooling system , losing coolant, does not over heat. I also had a oil test done for coolant in oil, none found. Tested coolant for exhaust neg results. I am leaning towards headgaskets or a cracked head. Any ideas out there?
