How is the heater plumbed ie Supply and return lines? You should be so lucky that it runs cool. Lol. Is the thermostat operating properly stick a meat thermometer in the radiator and see what kind of reading your getting?

Michael, Do you have any pics of how your heater is plumbed ? I have a 1500 also and my heater gets pretty hot. See if I can find a couple pictures of mine. PJ
Forgot to ad, I have a 180 thermostat in it.

Here's how mine is plumbed,

Paul,
Do you have a source for the shut off valve at the take-off point in your first photo?

Declan, That was an internet purchase and has a different wing knob than the one on the return side, which was put on the engine sometime in the 60s.

"4 Seasons Shut Off Valve", little pricey at $25.00+, but it works very well. I put a shut off on both sides for the purpose of removing any components in the system if need be without having to drain the entire cooling system to do it. PJ

gentlemen,
I found this one which seems to me very close to the original.

Declan, it is possible to mount it on your plate in place of the brass elbow ?

Thierry,
I had the same idea but.....
On my car there is not enough clearance between the plate and the bulkhead to be able to open the valve. I have one of those valves her and have tried it already. The valve is 50mm long when closed and 60mm long when opened and it has a thread 1/2" BSPP. There is a base plate available but this is flush with the bottom of the threads but it would save having to tap a 1/2" BSPP. I use 1/4" BSPP. On cars with the old Hi Gear Engineering 5 speed conversion kit where the engine was moved forward it would probably fit but would still be a tight squeeze unless fitted higher up on the plate.

Regards
Declan

Declan, you have to put a 90 ° elbow vertically

The connections on the radiator are 16 mm
Reduce to 13 mm is not too small?

Thierry,
I started fitting it this afternoon but I haven't removed the cylinder head plate plate yet. That will be done tomorrow. I am still deciding whether to take the elbow out vertically or horizontally as I want to fit the inline valve in that section. I am test fitting the heater return at the moment. I will paint it black before I install it.
Regards
Declan

Thierry,
The connections on my Smiths heater are only 12mm (1/2"winking smiley.
On my Morris Minor I also have a Smiths heater from a Mini with 1/2"" connections and it throws out quite a lot of heat.
The Smiths heater was installed so it can be swung aside for access to the gearbox filler.
Regards
Declan

Here is the diagram I want to make. Version 1 the copper pipe will pass over the intake pipe (in navy blue) for the return.
I want to mount a valve after the plate and one on the radiator elbow of the car.
I do not want to put a bulkhead, the rubber hoses enter the cabin with two grommets.
I will regulate the heating with a valve and the ventilation by a switch.
I put a heater that is intended for motorhomes easy to find here.

Declan, your fan and motor is different than the stock one in my Smith heater. Mine is not so good as it doesn't have the power and doesn't blow enough air. PJ
