just wondering about something that seems odd to me I notice when my car is at running temperature I can squeeze the rubber hose that turns down on to the top of the motor thermostat housing with my fingers seems like there is no pressure in my cooling system when car is at running temperature?
Car runs at a consistent 180 to 190 the fan circulates on off everything seems fine but I just was under the impression that the system have to be under at least 12 pounds of pressure?
When I squeeze that rubber section I can hear the
antifreeze slushing in the upper Stainless Steel Reserve Bank.
