If you haven’t changed your antifreeze in 2 years, it’s time. There are 2 ways to do have it done: yourself or a shop. It isn’t at all complicated and a shop can even suck out the old without climbing under the car. But if you do it yourself, you will need to dispose of the old properly, as it’s sweet smelling and very toxic if ingested by kids or animals. If you want to try it, see Ivan at the next event and he’ll show you how easy it is!
New to the American market is the so-called 5 year/150,000 mile extended-life antifreeze. GET THIS! Not because you ever need to leave your antifreeze unchanged for that long, but because it’s a different and far superior chemical composition. The old green-colored antifreeze contains phosphates and silicates. These can eat up the insides of your engine and radiator. The new amber-colored antifreeze doesn’t have these and has been used by European car manufacturers like Mercedes for a long time. The additional cost is about $1 per gallon, goes in the same way, and will protect your Miata much better. Protect your investment so you can continue to be a part of our runs without a break-down.
PS. And if your radiator hoses (5 all together) are over 4 years old, they’re due for a change too. Also easy if you can handle a pair of plyers and a screwdriver!!
