 |
|
I'm sure I've read this before but can't find it now...
Any advice on antifreeze products for classic cars? (In my case a 57 Ford Zephyr and 66 MGB).
There's lots of speculation on the web that newer products are bad for components in classics engines and radiators.
Cheers

| There's some info in a recent FBHVC bulletin ( http://www.fbhvc.co.uk/2010/03/31/newsletter-no2-2010/ about 1/4 of the way down the page). Basically, stick to ethylene glycol products unless you can get hold of a propylene glycol one, and avoid OATs! |

| Yup, agree 100% the use of bluecol, put the red or yellow antifreeze in at your peril (and expense). |

Blue antifreeze is blue because it has blue dye in it, no other reason. I did get some clear antifreeze before the dye was added but it was a bit hard to tell if there is antifreeze in the cooling system. The dye is in it so you can see antifreeze has been put in your coolant. Some manufacturers use strange coloured antifreeze so if you use other brands you warranty is void. - that does not effect most of us.

One point worth mentioning i feel is that the corrosion inhibitor will only be active for a year. The antifreeze capacity will actually cope for more than a couple of years. When you have an aluminium engine an annual change is an absolute must. That's why one gets quite a bit of corrosion on an aluminium water pump where the hose fits... a little oozes out and remains there and in time makes it's mark.
As for concentration i always do 40% - easier to mix [2L antifreeze - 3L water]. |

When I did the Rover just before the winter I used a hydrometer (only a fiver from Halfords) to set the correct strengh which turned out to be as jessejazza said 40 % so I premix mine the same way. Oh and only use Bluecol the newer stuff will rot the seals out an old car.

Hi Bayliss Thomas
Out of curiosity, what is in the red and yellow stuff that is bad for older engines?
