i just haven’t looked into the coolant since i bought it 2 years ago. The cooling fans were still on after turning the car off, so i thought it was a sign of some over heating. I added some water into the reservoir and that kind of stopped the fan being on after turning engine off. So i thought it was low on coolant and it was, so topped it off. I will keep an eye on it. But the car temperature gauge was still in its usual place.
