hi fellas
reading the forums i thought getting only luke warm air through the heaters was the HCV
but now ive been told that my car doesnt have one(94 si)is this right ?
****how do i "back flush" the heater matrix.****
there are two pipes about 25mm on the left hand side of the engine baygoing to the fire wall and going in and out of
a small, finned unit in front of the rad.are these also to and from the heater matrix ?
i tried bleeding the system by running the engine till warm and sqeezing pipes and did notice some bubbles
into the header tank,and a half a degree rise in heater temp.
engine temp normal.
heater controls leavers are working.
changed the thermostat.
