[Healeys] Heater query

[BJ8Healeys]

I live in the sunny South (90° F and 90% relative humidity today) and I used to refer to my BJ8’s heater as the “auxiliary engine cooler”; but I no longer have to use  it that way since I had a modern core installed in the radiator and added a 190° sleeved thermostat that I bought from Kees.

Ah, good point Kees. On a road trip coming out of Death Valley on a 115degF day climbing the Panamint Mountains my BJ8's temp started climbing rapidly towards 212. I turned the heater on full blast--not fun, but better than boiling. Temp held steady at 212 until we crested the mountains and it started to come down and we were back to just miserable.

I suppose you could close it if you don't expect hot weather and, if you think of it, turn it on if the weather turns.

Do not turn it off. It might save you from overheating the engine on a very hot day or fan failure. When you see the coolant temperature rise expectantly turn on the heating with the heater fan full blast for some extra cooling of the engine (but over heating the driver and SWMBO). However check first if there is any coolant in the system at all.

I have a MkII BT7 with a normal Smith’s heater. Normal insofar as it never seems to be turned OFF 100% or ON 100%.

We are in our summer(?!) at the moment and I was wondering about turning off the tap in the hose from the block that leads into the cabin for the heater.

Would the heater box and/or its valve semi-dry out and fill with a mess of rusty crud?

Would the engine run hotter as there was a little less water running through the system?

Or would I find myself basking in cool luxury as I tootle off to the local boozer?

Or, most likely, none of the above, especially the last one?!

I did take the car on quite a long trip the other day (Le Mans Classic!!) and, once the heat had soaked through the insulation, we were quite warm….

The more I think about this, the less I like the idea of turning that tap off…..

The tap does work, before you all shout at once!
