Hummer h1 cooling system air bleeders
hi friends i would like to ask you for suggestions regarding the hummer h1 cooling system.
1) after draining the coolant from the drain valve, I added about 17 liters. How many liters do you need? 2) today I dedicate myself to the level of the engine coolant. I filled the tank to the max and turned on the h1 from standstill by turning the main and auxiliary fan to maximum by moving the heater **** completely hot and waiting for the engine to reach normal operating temperature. the car remained stationary during this operation with the engine running without driving. When the engine reached normal operating temperature I unscrewed the screw of the 2 air vents but not much air came out and no coolant came out. because? I'm asking because I don't want to cause engine damage and burn the cylinder head gasket. thanks friend .
Greetings Gianfranco
