bbrendal: the temp needs to be at least 44 degrees to cool the truck properly....anything lower than that is a plus.....58 to 60 is not real good....but its better than nothing....your pressure sound ok on the system. take it out and drive down the road and see if it cools lower than 58 to 60 at road speeds....also check the rad. and between the rad and condenser and see if there is any trash between them. if so clean that all out real good and see if that helps....you can use compressed air and water to clean the condenser and rad. lots of it.....fan clutch is also an item to look at.....
