hot water

i own a Renault laguna 1.9 estate how can i tell what sort of coolant is in radiater waterless or standard as i need to top it up can both be mixed

[HustleRussell]

It won’t have waterless coolant in it, that stuff’s expensive. See what colour it is, top up with same colour.

I have always topped up with Prestone brand. This mixes with any antifreeze and I have never had a problem between coolant changes.

H.O.A.T antifreeze will mix with anything if you are in doubt.
