Appreciate some guidance,
I've a 2004 Ford Expedition, latelly I've notice that coolant comes out the coolant pressure bottle and periodically I've to add coolant to the tank. I've noticed that after getting the vehicle warmed up the gauge read 3/4 up, no longer half way. I also notice some small bubles coming from the coolant hose from the engine that goes to the tank. I've performed a head gasket test and did not notice any color difference on the results, also did a coolant flush with the thermostad taken out drove the truck yesterday and no overheat. any suggestions. Do I've an air pocket? do I have a blown head gasket? any recomendation would be greatly appreciated.
