the heater on my daughters "new" durango isnt putting out as much heat as it should. i found the coolant was about a gallon low, and the lower radiator hose clamp was the culprit. even after topping off the system, its still not producing enough heat for the upcoming montana winter. on the interstate it does fine but as soon as you come to a stop the air temp drops to just a little above warm. its acting like its still low on coolant but the coolant level is fine now. the coolant housing has a bleed hole with a bolt on it, is air lock a common issue? when/how do you use this weep hole? thanks,
