The Triumph Dolomite Club - Discussion Forum

It seems the bluecol for classics is the "2 year" version with non OAT technology. Where are you guys getting it from? Ive seen it for £12 per litre which seems a lot. Is that about what people pay for it here?

Cheers

Tony

i usually pop to my local small garage and get it from them, 5 ltrs of none oat was £15
i did take my own container as they have it on "draft"

For the last 2 coolant changes I've been using Comma Coldmaster Antifreeze (ready mixed) - no issue at all.

Thanks guys. I did think about he comma too

Speaking to an engineer recently that clearly knows his stuff, he has told me to use Toyota antifreeze, red colour, it's called 'for life' it's totally non corrosive and will never attack aluminium, and won't turn corrosive with age.
I work on Citroens, the C1 has the 1.0 litre Toyota 3 cylinder engine. The coolant is never changed and even now the older 56 reg cars, the coolant is still a nice bright colour....always. So, may try this in mine. Alternatively was thinking about Evans waterless coolant but I know little about this stuff, has anyone tried it?
Must also remember if normal antifreeze is not ready mixed, distiller water must be added 50/50.

Do you mean this stuff? http://www.demon-tweeks.co.uk/motorspor ... ne-coolant
I've been using this for years in a Midget, an Elan and in my V8 MGB. It's great. Fit and forget. Your engine will never boil over as the boiling point is something like 180C. You use it neat.

I use Evans waterless coolant,
the Powercool 180 being the correct version for Dolomites (rather than the vintage or classic version).

It really is fit and forget, but then when you look at all the manufacturers who specify it for their vehicles you realise that it must be so.
There is no difference to the running temperature indicated on the temperature gauge but my experience demonstrates that using
Evans WC removes the notorious hot spot from the back of a slant four engine.

The economic case for using Evans coolant is overwhelming, you are in the money after 5 - 7 years.

When you get to my age perhaps not so.

Only if in those 5 - 7 years you never have to drain the cooling system for any reason. In my experience with older cars, that's not likely. I know of one extremely experienced and highly thought of engine tuner who tried it and rejected it because it made the engines run too hot. Water is the best heat transfer medium, whatever anyone says.

I have got to admit that with all of my Triumphs I have used Halfords anti-freeze and de-ionised water.

Seems to have worked well for me including in the Spitfires.

Recently bought the neat blue stuff from euro car parts. Cheapest way was in 1l bottles!
Own brand, but can't see it being different to other makes?

I would very much hesitate to use OAT coolant, it does not do solder ( or is it yellow metals?) any favours is rads, heater matrix etc.

As to Evans, a mate arrived at Triumphfest in his Cossie. Just put Evans in at at a cost of £180.
Stone holed his rad. He was frantic searching for a container to catch the coolant. Managed to save nearly 3l, but still cost him another 5l tub. He reckons the engine ran a touch hotter with the Evans, which is likely as it is not as good at heat transfer as water. But not much difference. May not be so good with EWP as more vicious too.....

That is so, but why Evans coolant is able to better water?
Evans coolant makes contact with all surfaces at all times…….

Just found a Morris version of meg based:

Under £2 a litre if you purchase 20 litres

I have used Bluecol at abouyt 25% for donkeys years.

It regularly lasts 5 years or more between changes...

Its best with distilled water to avoid limescale but sometimes needs must....

You want to look at specific heat capacity, cavitation being a much smaller problem if your cooling system is working as it should.
Anything more than 25% reduces the heat capacity and is unnecessary unless you live in an area with high likelihood of 15 degrees of frost.
