thailand triumph stag

[keithdewart]

I spend quite a lot of my time in Thailand so acquired one of probably a maximum of 3 stags remaining in Thailand, I bought it with a Nissan straight six engine fitted and decided to ship in a stag engine.
First reaction from everyone was if they overheat in the UK it will boil itself to death in 40 degrees of heat.
we played around with the cooling system fitting a better expansion tank, radiator cowling and made improvements where possible to the cooling system. To date its never boiled over (my fingers are still crossed) the gauge usually sits at just over half, it does not like sitting in traffic but neither do I in the Thai heat.
Generally I am happy with the stag's performance so far, does anyone else have an experience with owning a Triumph in a very hot climate?

There was TV programme called For the Love of Cars were they examined the Stag cooling system from a modern car point of view and found no deficiencies in the system design. The hypotheses they came to was poor initial coolant filling by the factory leaving airlocks in place.

Raf, you forgot the mention the casting sand that was left in some heads that caused silting in the radiator. A new radiator with more cores does help along with using the correct strength glycol-based antifreeze. I've never had a major problem with the cooling system on any of my Dolomites and I've always changed the coolant when necessary.

'Tis true, my post was just the headline result from that programme, but as you say, casting sand left in the water galleys is a long known about thing too.

I enjoyed watching the series, but for a Stag owner I recommend watching the episode in the link I posted, and if you're over in Thailand I'm sure there will be a 'dodgy' version on YouTube.

Keith,
An interesting story and very ambitious of you. I am pleased that things have worked out well with the Stag.
I haven't personally owned a Triumph in a hot country, but I did work for a very short while in a British car shop in Texas, where it was plenty hot enough. There didn't seem to be an issue with cooling in any Triumphs over there.
I think that as has been said, if the system is set up properly and kept in good order there should be no problem. I hear stories of TR3s overheating on motorway journeys and the importance of a radiator cowl. My car, which incidentally came from Texas, isn't fitted with a cowl, and has never shown in inclination to over-heat. I rebuilt the engine with new liners and removed a lot of sediment when it first arrived on these shores.

Stags also suffered in hot climates because the absence of anti freeze with corrosion inhibitor soon caused corrosion
and head gasket failures.
