Hello List:
I will buy the recommended 860/187F for my BJ8 and join anyone who wants to
make a Group purchase from Kees. After reading all the comments the past
days, I need to remodel my cooling system with a thermostat and fans etc
before contemplating a new core for the radiator.

Subject: Re: [Healeys] Radiator cap thermostat combinations
This discussion took place during my holiday in San Diego/Las Vegas/ Grand
Canyon/Mohave and other Deserts, Quartzsite etc.
I have tried to respond but I am uncertain if anything at all came through,
the WiFi in most h/motels was atrocious, very slow.
For your information I still have the following sleeved bellow thermostats
available:
4 x AC TF1, 720C / 1620F
3 x AC TF3, 680C / 1540F
4 x AC TF4, 860C / 1870F
2 x Smiths 85025/.., 860C / 1870F
2 x Smiths 85025/.., 800C / 1760F
1 x Smiths 85025/.., 820C / 1800F
Smiths and AC thermostats are interchangeable/equivalent. Smiths was mostly
used as OE on the AH, AC on the TR2/3/4.
Officially these thermostats should be used with a pressure cap of no more
than 7psi to prevent collapse of the bellows, however I know of several
people that use 10psi pressure caps without any trouble.
If you have sufficient,meaning overcapacity of the radiator, or if your
engine does never run hotter than say 50 over the opening temperature of the
thermostat, use the 860C / 1870F thermostat with a 7psi pressure cap plus
proper overflow bottle. The engine will run better and more efficiently.
Fill up the radiator to the top of its neck and the overflow bottle to half
way with the tube reaching the bottom. After topping up a few times all air
will be expelled from the cooling system and the radiator will be fully
filled up with coolant.
If your car runs to hot at any time there is no way you can fix this with an
other thermostat with a lower opening temperature, you just buy a little
extra time only before the engine starts boiling
If you want to buy thermostats ($40 each, except the AC TF3 which will be
$55), get a few mates together (AH, TR2/3, Jaguar etc.) as shipping 1
thermostat to the US costs the same as shipping 13, i.e. $31 registered post
(parcel up to 2kg).
