Anti-Freeze

It's just as important to check up on your anti-freeze in the summer as you would in winter. Modern OAT anti-freeze contains anti corrosion inhibitors and have a life span of approx' 5 years. Traditional IAT anti-freeze are normally coloured blue or green and normally has a life span of two years and is available in RTU (ready to use) or in concentrated format. Personally my water element is deionised.

A visual check of your anti-freeze is a good start, should it be murky in appearance I would change it. You can purchase test kits and you should be looking for protection down to -25 centigrade or more.

While you have the bonnet up it's also worth checking for any minor leaks that can be seen by looking for the tell tale staining around joints, hoses etc. If you do change the anti-freeze I suggest back flushing the system to help clear out any debris prior to rep-filling the system, normally 50 / 50 mix is used but please adhere to any product instructions. The last thing to remember is to bleed the cooling system out thoroughly and re-top up the reservoir when the level drops as the air is dispersed. (I think the design makes bleeding the Scimitar cooling system a bit of a sod). The above presumes that you are familiar with bleeding out cooling systems.

Hope this helps
