No coolant to heater core
Hello all,
Been chasing a problem on a 2010 Honda accord with a 2.4 4 cyl.
short version is that there is no coolant getting to the heater core.
I removed both hoses from the fire wall and ran the car with the radiator cap on and off from cold to running temp and the fluid barely trickles out
the car does NOT overheat, ever
new thermostat
full of coolant
did not change the water pump as i have no reason to believe that's the problem.
I'm looking for suggestions on what to try to fix or diagnosis the issue
i flushed the heater core both ways
to be clear, there is no fluid getting to the heater core, has anyone seen this before?
thanks
