Hello people,

The coolant in our Matiz has never been changed as far as I know. I bought new organic coolant like prescribed and I want to change it.

I want to empty the coolant by loosening the lower coolant hose. After this I want to fill the reservoir with demineralized water to flush the system. After driving a short while emptying the system again and filling the system with new clean coolant.

Is this the proper way? Are there things I have to take in account so air does not get stuck in the system? What is the correct procedure?

By the way, I do not know what kind of coolant is in it right now. Therefore the flush. Or can I just empty the system and fill it with the new coolant? So no flush needed? Can 2 different (old and new) coolants mix together?

Thanks

There are numerous generic methods suggested on the internet (many with video).

The two things over the years I have found important are (i) open the heater settings (to hot) on the vehicle heater, and (ii) top-up very very slowly so the fluid has a chance to flow down through the tubes. A bad sign is if the fluid 'bubbles back' which means you are pouring in too fast. This what can trap pockets of air.

Oke cool thanks. I was just curious if there was a specific Matiz related procedure. If it is the same way like with other cars, then it should be no problem to change it. (y)(y)

Abi, If there are some 'peculiarities' associated with the Matiz I'm sure one of our Matiz guru's will say.
