I had to put a radiator in my 18' Equinox with a 1.5 turbo with 1,000 miles and for the life of me can not get the air out of the system. There is times I think I have it out and go and drive it and sometimes can go 5 miles then starts to overheat. I have done a combustion check over the expansion tank with showing nothing, leak down test with maybe a lb or two different and a pressure check of the
Cooling system. When doing a pressure check the antifreeze will lower in the expansion tank. The heater core sometimes has the gurgling sound. If you touch the upper rad hose it would be hot but the lower would be very cold.
