I had my first test days after installing the SD radiator at NJMP with the ambient temps in the mid-high 80s. Water temps exiting the head (at the stock gauge location) were pretty much locked at 180F.
I've got a pressure sensor in the heater core bypass hose, and was often only seeing 2PSI, which was setting off the alarm on my dash...
Is it common to have very little pressure in the system with the water temp running so cool?
Thanks!
