Hi,
Just fitted round heater to my 54 splitscreen. New mechanical take off valve, hoses & return to btm of rad. Flushed & refilled system. Run engine up to operating temp but heater hose only gets hot as far as bulkhead. Removed hose from btm of rad, connected garden hose & water flowed thro htr & out block drain tap. Cannot access htr hoses in situ. Heater fitted under centre of dash. Help!!
Bill.

Re: cold heater
probably air locked, squeeze,the hose by hand to try to pump the air out of the system.

Re: cold heater
As above - likely an air lock. I've always found that just taking the car for a run, so the revs increase and decrease over a period of time, gets rid of the air locks. If it's just been sitting idling up to temperature, there isn't enough flow to shift the air.

Re: cold heater
