Puglet1 Posted November 3, 2023 Report Share Posted November 3, 2023 Sorry. It seems like a silly question but what colour antifreeze should I put in my Mk2 vitesse? The current fluid is rust coloured and I have not changed it since I purchased the car so don’t know what the previous owner filled the system with. I am also thinking about changing the hoses, should I replace them with silicone ones? Many thanks. Pete. Link to comment Share on other sites More sharing options...
Nigel Clark Posted November 3, 2023 Report Share Posted November 3, 2023 Blue glycol antifreeze is the standard recommendation for our classic Triumphs. Around 30% concentration and change every 2 years. If you've got rusty coloured coolant, give the whole system a good flush. Alternatively, flush the system and refill with premixed 4Life coolant, stocked in the club shop, which has superior corrosion inhibitors and can last at last 10 years in my experience.

GrahamB Posted November 4, 2023 Report Share Posted November 4, 2023 I bought 5 litres of the blue antifreeze concentrate and dilute it to the required concentration when needed. I have never used the 4Life coolant as nearly every year I have to at least partially drain the system to replace a hose, remove the inlet manifold or replace a seal. On my Spitfire I have yet to find a method of draining coolant without contaminating it so lasting 10 years is purely academical and the standard antifreeze is a lot more economical.

dougbgt6 Posted November 4, 2023 Report Share Posted November 4, 2023 One of ours at East Berks bought a Vitesse, decided to do a service and drained the coolant only to realise, too late, it was 4life! An expensive mistake. Silicone hoses? How long do you intend to keep the car? I changed mine for standard and after 7 years I'm periodically checking too see if they're OK. Silicone will last much longer and you can get pretty colours , but even black are expensive! Doug Link to comment Share on other sites More sharing options...

I use 4Life and when the cooling system needs work, I drain the 4Life then filter and reuse. Nigel 1 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted November 4, 2023 Report Share Posted November 4, 2023 Blue Glycol, sometimes that green Prestone stuff from Tescos (when they drop the price to clear!) but if you're replacing hoses, go for good ones - as Doug says they need not be silicone, but some kind of reinforcing, Kevlar or canvas, is needed otherwise they'll split quicker than Santa's trousers on Boxing Day.

Yes, I guess we are going to be doing various bits and bobs on our 50+year old triumphs so it probably makes sense to use Blue glycol. Thanks for your opinion. Pete.

It’s probably how long I’m going to be around to enjoy the car? It’s so easy to look at buying the best materials (silicone) ones and overlook the obvious. Search will start for high quality standard hoses now 👍. Thank you. Pete. Link to comment Share on other sites More sharing options...

Hi Colin. It looks like it’s going to be blue glycol with either Kevlar or canvas hoses. I’d rather not experience the same as Santa if I can help it 😂 Thanks for your help and putting a smile on my face 👍 Pete. 1 Link to comment Share on other sites More sharing options...

PeteH Posted March 10 Report Share Posted March 10 I`ve been doing some service work on Plum, in the course of which I checked the Antifreeze concentration. It`s reading -22, which in my view will be sufficient. However the colour of the coolant, to my surprise, was Pink?. Reading on the `net is somewhat confusing as it appears unlike "the old days" when all you got was Blue there is now a plethora of "Gay" shade`s, some of which indicate incompatable formulations. I would hazard a guess that this is either ethylene glycol or maybe propylene glycol, but which is which? and can they be mixed?. As most of you will be aware, it`s sadly not as if I can ring and ask the P.O. I have a shed load of the bog standard "Blue" type, but just a little concerned about using it. I supose the "safe" way would be a drain.flush etc; but not in my gargage and the Motohome parked in front makes taking it out a bit of a marathon. The hoses all look good I think Jeff, had recently changed them. Pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 10 Report Share Posted March 10 i think pink is generally OAT you cant mix it with BLUE it will jellify. dont think pink is advised on old cast block motors as there will always be residue of the previous blue stuff , blue has improved over the years way back it disolved alloy parts they developed a alloy compatible call AA that seems to have disappeared . i think if you want to use blue you need a strong mix of washing soda to clean out all the system then refill with blue , do not take the chance of mixing blue and pink as the air will be blue !!! im sure there will be a lot of bright ideas about the Pink stuff Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted March 10 Report Share Posted March 10 I was very surprised to find my BMW takes the blue stuff, which makes things very simple for my garage. Of course everyone else's modern takes pink, and the Herald estate is now on the green Prestone stuff (reduced to £10.50 for 5l in Tescos.) I don't know if that stuff can be mixed with anything else, there are no warnings on the container, but I'm still using it on a completely drained system with no residue of anything else in the engine already.

Richeee Posted March 10 Report Share Posted March 10 This happened to myself. Not sure if it was K Seal, Blue ,Pink or any other colour of the rainbow. if im not sure it all comes out to be replaced by one type. Once bitten......... Link to comment Share on other sites More sharing options...
PeteH Posted March 10 Report Share Posted March 10 One of the more confusing things, that is apparent, is that some "glycol" based products come themselves in a variety of "Gay" colours too. The current stuff looks clean, suggesting it`s not long been in, and as it`s recording a decent level of protection. My gut feeling is to leave it until she comes out of hibernation for the "season" and then do a full flush and refill, probably along the lines Pete was suggesting, and on the gravel frontage rather than my garage floor.

DanMi Posted March 10 Report Share Posted March 10 The colour of coolant doesn't mean much at all any more, some can be had in multiple colours so you really have to go by the chemistry. Penrite do a blue longlife OAT https://penriteclassicoils.co.uk/product/7-year-blue-coolant-anti-freeze-premix/#:~:text=Penrite 8-Year Blue Coolant,degredation of the cooling system. but it can also be pink green etc depending on manufacturer Link to comment Share on other sites More sharing options...
johny Posted March 10 Report Share Posted March 10 In the end I find one of the biggest factors is how bright the coolant colour is so you can easily confirm the overflow pipe and bottle (if fitted) are correct... Link to comment Share on other sites More sharing options...

Stratton Jimmer Posted March 11 Report Share Posted March 11 I have Evans Classic Cool 180 in both cars on the basis that these are old engines and the last thing I need is corrosion from within the water jacket. The Sixfire has silicone hoses while the GT6 has standard hoses and both seem to be fine. If needs be, I drain the system, filter the coolant and re-use it topping up with a few egg cups of new stuff. Link to comment Share on other sites More sharing options...
johny Posted March 11 Report Share Posted March 11 Is it good for confirming your vent pipe is full? Link to comment Share on other sites More sharing options...
