Thread: Heater core - replacement

It was a locally sourced heater on the Australian models.
I don't know if the core is unique or based on something off-the-shelf so you might have to find someone parting out an Australian Series III.
Alternatively a radiator repairer might be able to re-core it.

The ON/OFF valve looks like it's been bypassed.
Is the core leaking ? If not is it blocked or just not correctly connected ?

You also have to realise that the heat output was below average as standard so maybe your heater is OK.

indeed. The heater in my S111 was put there merely to increase the opportunity for leaks, and those Ford engines didn’t run very hot, and the application wouldn’t have been very demanding.

I drove My S3 SWB Daily to a Land Rover coffee morning.
Door tops off and sides rolled up. Passenger said, when picked up, 'Thought you were joking about the door tops coming off'
4 Oc when leaving at 5.30am. Glad the heater actually worked.......Well an Hr down the road when the motor warmed up.
Most of the Land Rovers I had with Holden motors fitted had heater disconnected.

The valve could be the source of your issues as well. They corrode open or closed and then don’t run anymore. I think the easiest replacement for the valve was an off the shelf one here in OZ but I can’t remember the car model (think it was a Ford, maybe XY). Cheers, Matt

UK parts sites don't seem to show this style of heater.
Thanks

The heater valve is disconnected in the photo.

I think from memory you have to re-orientate some parts to replicate the Series III valve.

So it is - you’ve got a sharp eye Colin! Cheers, Matt

The heater taps are serviceable.
I have pulled two apart, cleaned and replaced.

Thanks guys. I had kept the original post short but now the eagles have landed...
The heater valve was disconnected when I started to investigate lack of calories in the heater.
Removal and bypassing it made no difference whatsoever. I did renovate the valve and it now works but didn't bother plumbing it back in.
The Ford motor doesn't run very hot in on-road use as people have noted. I even took off the fan to get the water hotter..
It copes well even when idling for 10 mins but when off-roading/sand driving it would boil after 20 mins or so - so fitted Kenlowe style electric fan to cope set to switch on at 90C.
Even then heater was useless with temp of both inlet and outlet hoses going up to 85C

Tried testing water flow with outlet pipe from heater off - gallons spurted out with engine running, so no obvious full blockage.
My guess the water is simply bypassing all of the cores somehow.
No leaks nowhere.

Oh well, I might just have to pull the thing out and see what's what and find a radiator person.
cheers
