[QUOTE="Buellstunter, post: 721062, member: 11549"] Quick question about cooling system pressure. My truck is studded and deleted along with a few more minor mods. All was done around 3000 miles ago. Was towing 3 dirt bikes and two 4 wheelers a week ago. I pulled a big hill and the truck puked about 3/4 of a gallon of coolant. Now I did have coolant level at the top line of the bottle. Was watching the dash gauges all along. And the gauge was holding 1/2 all day and it shot straight to hot with no warning. Long story short refilled and finished the weekend with no more issue. Put a gauge inline from top of rad. To coolant bottle. After 1/2 hr idling I had like 2 psi on the gauge. Took it for a small drive about 4 miles and it hit 6 psi. And was only boosting at 20psi max at any point. Drove it today about 40 miles and it hit 9psi. After the drive. Left it idle about 5 min and it dropped back to 5psi. Does it sound like gaskets are going out again? Thanks in advance. [/QUOTE]
