RayHutch Posted May 9, 2019 Report Share Posted May 9, 2019 Which antifreeze should be used on a 1969 Vitesse? A recent hose failure caused a loss of coolant and I topped up with water (a lot). Also, I’m in a hard water area, is it ok to use tap water? Link to comment Share on other sites More sharing options...
Guest Posted May 9, 2019 Report Share Posted May 9, 2019 Hello Ray. You need to use BLUE anti-freeze, I use Granville Sub Zero Blue - it's an excellent product. Do NOT use OAT (pink / orange) antifreeze. Secondly, DO NOT use tap water, you should use a softer water such as distilled or de-ionised. You can purchase these 2x different types for a £1 or so at Tesco / Sainsbury etc and usually comes in 2.5Ltr containers. Mixture wise, anything between 25% to 50% and of note if you have an iron block with alloy head you should use the higher % mix. However you have iron and iron, so go for about 30%. This would also be a good opportunity to flush your coolant system through. Hope that helps ?? Regards. Richard. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 9, 2019 Report Share Posted May 9, 2019 Use a glycol based blue and if you dont like tap water , buy some demineralised Its probably used tap water for the last 40 years bit late to worry now Of you want to flush the system just use a strong mix of cheap washing soda from a supermarket Two cup fulls and wash /hose out after a couple of days Dont add any pink OAT based it will not mix with any previous blue AF. And can turn to jelly Pete 1 Link to comment Share on other sites More sharing options...

RayHutch Posted May 9, 2019 Author Report Share Posted May 9, 2019 Is this the right Granville coolant ? There seems to be a couple of options Link to comment Share on other sites More sharing options...
Guest Posted May 9, 2019 Report Share Posted May 9, 2019 Yes Ray, spot-on that is the stuff. eBay do good prices and of course best VFM is the 5L unit. I found this 5L offer with ONLY 2x left - not surprising at the price and I have purchased from the company before, so I know they are okay. https://www.ebay.co.uk/itm/Granville-Sub-Zero-Blue-Concentrate-Antifreeze-Summer-Coolant-5-Litre/142791110505?epid=2257218373&hash=item213f036f69:g:q9MAAOSwuTta9aqN&frcectupt=true Regards.

rlubikey Posted May 9, 2019 Report Share Posted May 9, 2019 Just too late for you, RayHutch. But anyone considering antifreeze for our cars might note the MG document mentions Propylene Glycol and that it is less toxic. Ethylene Glycol is highly toxic and needs to be disposed of carefully, not just thrown down the drain. It was infamously added to a batch of Austrian wine many years ago. Although the PDF says that Comma have stopped making Propylene Glycol antifreeze, I believe it is a legal requirement that central heating antifreeze uses Propylene Glycol so that children and pets aren't poisoned by leaky radiators! I use Fernox Alphi 11 in the Spit, and there is anecdotal evidence on the web that Rolls Royce used to specify this product in their cars. Another advantage is that the anti-corrosion agents in central heating antifreeze such as this last for 20 years or so, not the 2- or 3 years which is normal for blue antifreeze. So taking this into account, the more expensive central heating product works out cheaper in the long run. Cheers, Richard 1 Link to comment Share on other sites More sharing options...
