RAD look clean but not sure if its blocked
took the cap off when it stiill warm lots of coolant flow out form the RAD
maybe its not flowing but when run on higher rmp its seem to flow
not sure how to check the thermostat and fan cluth
is this a commom problem?
i am lost!!!
no loss of coolant and no bubbles
but its runs cool when coming down the grade or highway speed or normal driving
its only runs hot when engine understress
it runs hot when going up steep grade or in traffic with the a/c on or towing
dont know whats wrong just got the coolant flush and its still runs hot
any suggestion would help
thanks in advance
