Subject: help please !!! heater hose routing IP: Logged
Message: 1987 3.9L, i bypassed my heater core years ago. just changed out the heater core but can't remember how the hoses are routed.
is the htr.control valve in the hose that goes from water pump to htr.core?
which hose goes to the top of core and which to the bottom?
tried to look at the pics in repair book but can't make it out clear enough.
poor truck has 242,000 miles on it :(
