there is very little heat coming from blowers i have bleed the system until hot water came out of the bleed valve on thermostat housing. there is no bleed valve on radiator so couldnt bleed from there.

but still no heat from blowers i was thinking of back flushing the heater matrix so i would like to know which pipe is the inlet.

any help at alll will be appreciated

did you have the heaters on while you were bleeding?
this is the only way i have done this and it has allways worked, for me anyway

the 2 pipe's on the bulk head are,
top, goes to the back of the cylinder head,
and the bottom goes to the thermostat housing, so the bottom is the inlet

if thats the info you needed : )

Strange, mine are the other way round, bottom to cylinder head, top to thermo/expansion tank.
