Changing the coolant / antifreeze in your car

Keep it cool

Here’s something that you don’t have to do everyday or even every year. Making sure that the coolant level and quality are at the optimum point is part of every regular inspection. Because the coolant or antifreeze is a closed circuit and thus not supposed to leak or lower over time (in theory).

Anyway, in some cars it’s supposed to last a lifetime, in others the manufacturer recommends to change it every X amount of years. On my RCZ, the coolant level slightly lowered over the five years I owned it so far and I topped it up with tap water. Naturally, that dilutes the actual antifreeze substances. So when I saw that it was low again, I decided to flush the system and put all new coolant in it.

At this point you might ask yourself  whether my car has a coolant leak somewhere. I could never find any and even had a Peugeot workshop have a close look at it. They couldn’t find anything wrong with it either and just mentioned that some of it might just evaporate through the valve on the overflow reservoir cap…

Anyhow, long story short. The following video shows you how to change the coolant on your car. Although this is shown on my RCZ, the procedure is pretty much identical on any car! 🙂
