CosKev Posted November 9, 2023 Share Posted November 9, 2023 You don't need anywhere near 50% strength mix of anti freeze,unless of course your car is sat outside over winter? Antifreeze lowers the waters cooling efficiency, which in our small cars with not much airflow through the engine bay isn't a good thing! 2 1 Quote Link to comment Share on other sites More sharing options...

Antifreeze lowers the waters cooling efficiency, which in our small cars with not much airflow through the engine bay isn't a good thing! Agreed. In fact, assuming the vehicle is kept in a garage and doesn't go out when the weather is below or very close to freezing, the only reason you need antifreeze is because all reputable makes of antifreeze, of whatever colour, contain a corrosion inhibitor. This is essential if there is both iron (or steel) and aluminium somewhere in the engine and coolant system because as I'm sure everybody on here knows mixing water, aluminium and iron will generally cause the aluminium to corrode to a crumbly oxide. I believe it is an electrolytic action. So a mix of 2 parts of water to 1 part of antifreeze will be fine in a Westfield in normal use and storage. It's different in your daily use tintop of course. 4 Quote Link to comment Share on other sites More sharing options...
Andrzej Posted November 9, 2023 Share Posted November 9, 2023 Mocool and Water Wetter claim that contain anti rust/anti corrosion agents. 1 Quote Link to comment Share on other sites More sharing options...
eggontoast Posted November 13, 2023 Share Posted November 13, 2023 If your car is stored outside over winter, what's the advice e.g. cponcerning antifreeze? I have looked for an 'overwintering' thread but haven't seen one coordinated source yet, such has arisend for brake pds for example, but varied scattered advice. Apologies if I've missed it. EDIT: Happy to start a new thread for this, as there's a divergence from purely coolant chat. Quote Link to comment Share on other sites More sharing options...
Andrzej Posted November 13, 2023 Share Posted November 13, 2023 Regular universal Prestone ready for use coolant and will be fine. Can be mixed with other coolants and I use IT for years in different cars including standind whole winter outside (below -20deg no unusal here) . 1 1 Quote Link to comment Share on other sites More sharing options...
stephenh Posted November 17, 2023 Share Posted November 17, 2023 EggonToast, just use a reputable brand of antifreeze, same colour as is in the system already (unless you plan to completely drain down and flush) and mix in accordance with the manufacturer's recommendations. I think for our climate that is usually 50:50, but don't hold me to that, read what it says on the tin! 1 1 Quote Link to comment Share on other sites More sharing options...
