when looking at firewall from front.......hose entering the firewall to the heatercore (left hose) was apprx 160 degrees

when looking at firewall from front.......hose exiting the firewall from heater core (right hose) was appox 130 degrees

not too bad if you ask me, ofcourse there might be some cooling of the fluid in the heater core as air does pass through it.......just like a radiator.......


ANY OTHER IDEA'S PEOPLE....I hate to bring it to the STEALERSHIP[:@]

AND please remember...it is cold up here at fort drum newyork 30 minutes from canada
