Was changing my heater valve and hoses and not sure if they were hooked
up right. Parts supplier says lower hose is the U shaped one and is the
output. Brick boards say the heater valve connects there from the head
under the intake which would make it the input. I can't find a coolant
path on the net for the b230ft. Anyone know how the heater hoses hook
up? I bought the car used and have found some things not properly
serviced on the car. TIA

From the heater tap coolant flows to the bottom connector on the matrix then
out of the top of the matrix to the other line. IIRC the heater pipe from
thermostat housing goes to the tap and re-enters at the head.

All the best, Peter.
 
Thanks Peter. I'm still a little confused though. I have no heater pipe
from the thermostat housing. Seems that the bottom connector is where
the coolant goes in but where does the coolant come from, the pipe
behind the engine that runs along the right side to the water pump
area, or from the left side of the head under the intake. Thanks again

Water pump area, Dave, should go to tap.

All the best, Peter.
