Corse the heater output temperature not only depends on the coolant but also the outside air temperature - colder air in colder out. However once your engine is warmed up the thermostat should control the coolant temperature regardless of air temp but as they are pretty crude the range can be quite wide and then because the car temperature gauge is calibrated to a narrow range any slight change can look worse than it really is....

In very hot weather
Hot air not only flows through the rad but also flows over the engine
In very cold weather
Cold air flows through rad and over the engine
so in theory in very cold weather the engine could never get “up to temp”
And in very hot weather it could be “ up at running temp” before your even start the engine
And yes I’m mean in “ over extreme temps” at both ends of the scale

So to answer Dazzer original question

It all depends on the weather,and if your moving

Blank some of the radiator.

When I had an MX5 radiator with a 1300 engine I had the same issue. I had to blank over half of it in winter to get warm air.


Acclaim - fully working and on the road
13/60 Herald - mx5 powered and other such fun things, legal enough...
Mk1 2000 - it's still alive, just sleeping
Expert 815d - the slug

If in doubt, do up until you hear the crack and then go another 1/4 turn to ensure tightness.

I am struggling to believe that air flow past the engine is enough to  drop the temperature of the coolant in the block. You would struggle to get the car to run cleanly. The radiator should be stone cold as the thermostat should be closed.

What temperature thermostat are you using? I run my 13/60 on an 82 Degree, but Triumph also recommend an 88 degree one for cold conditions. Cheers, Dave.


First Triumph: 200cc Tiger Cub. Followed by in no particular order, 350 and 500 Royal Enfield Bullet, Herald 1200, Herald 13/60, Mini 1275 GT, Vitesse 2L convertible, Audi 80, Audi 80 Sport, Fiat 124 Sport Coupe, Triumph 2000, Mk 2 Estate, Fiat Tipo, Fiat Stilo, Fiat Uno, Peugeuot Turbo Diesel(yuk), Lancia HPE 2000ie (wow! a dream!) So far 3 Heralds and My fourth Vitesse in the garage. I may have forgotten some... It's my age.. Oh , Honda 400 four.. Terrifying! And the 2 Renault 5s. Oh, and the Ford Granada 3 litre estate..I think that's the lot.

I have this issue with my A6 TDI.

It always takes a long time to warm up, even in summer - it's a direct injection diesel - they don't waste much heat.  However, if the thermostat isn't spot-on' it'll never warm up unless you're caning it and even then will take 15 miles.

The correct OE thermostats made by Wahler have a rubber seal to give tight shut-off.  They cost £40 + in UK.  You can buy will-fit alternatives from reputable manufacturers but they don't have the rubber seal and it would seem that they don't seal well enough as I've tried two now and they are worse than the slightly shagged proper one.  They work as expected in a saucepan and seem to shut fully but don't have the desired effect.  I've just bought the real deal (from Germany at half the cost of the cheapest I could find here) so we'll see.

Guess the moral of the story is even a little flow will go along way if there's not much waste heat.  Moderately surprised this is an issue with a Triumph 6 though - the Vitesse gets up to working temperature in about a mile - quickest one in our fleet.  Heater still rubbish though somewhat improved now the crappy Smiths valve has gone to live in the bin.....
