[Healeys] Thermostats

[simon.lachlan at alexarevel.plus.com]

With reference to Steve’s email, below.

I have bought one of the theremostats.

There may still be two remaining. Seems to be a good price.

I will buy the two of them – if still poss – and will send them both to a single address, anywhere. All to be reimbursed, at cost, by PayPal.

Off to Spain for a few days tomorrow, so better get moving?! Back next Tuesday. 

Don’t know if these things sell quickly or not.

Up to you guys.

Simon

Fred, I personally believe a 160-deg. F thermostat used in an effort to "cool down" a Healey is useless.  A thermostat responds only to the temperature of the coolant flowing through it by opening up to increase coolant flow, and once it is open all the way at 160+, it is out of the loop and can't open further to cool more.  I am on the NC coast where winters are mild.  I once tried a 160 (non-sleeved) because I had one that someone gave me.  My BJ8 ran so cold that winter that I actually had to block part of the radiator to raise it to anywhere near normal.  Up there in the NC mountains, that would be even more of a problem for you.

I use a 187 F (86 C) New Old Stock AC sleeved thermostat (AC part number 1572320) that I was able to score from lister Kees Oudesluijs.  I installed it along with an upgraded core in the radiator at the same time, so I can't really say how much improvement the thermostat alone did; but since the modification my car runs consistently at 170 - 180 in the hot summers of the NC coast, except when in stop-and-go traffic when it might make it to 190 or a bit above.  In winter, it runs at 160 - 170.  I can see the sleeve operate as the car warms up because the gauge will cycle between 160 and 190 until coolant temperature stabilizes.  That can take up to 50 miles.

A friend placed an order later with Kees for several of the 190 F sleeved thermostats.  I got one of those as a spare.  Don't know if he has any left, or can get more.  As far as I know, the only sleeved thermostats available from the usual suspects are 160s and I wouldn't waste my money on them.

I just Googled the AC part number and came up with this source:

Unfortunately, it does not post to the USA (but on the bright side, it offers free shipping!).  Maybe you could work out a deal with a UK lister to buy one for you and ship it to you.  £19.99 = $26.04
