Burna Posted June 24, 2020 Share Posted June 24, 2020 It's pre-mixed, you put it in as it is mate. Quote Link to comment Share on other sites More sharing options...
Tyson Posted June 24, 2020 Share Posted June 24, 2020 Yeah as is, the chemical properties of the coolant will be messed up it you add water into it. It’ll create hot spots and promote rusting if your using tap water! Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 24, 2020 Share Posted June 24, 2020 I think if you add deionised water you'll be fine, it's what I add to the concentrate. Coolant concentration is a balance, water is better on it's own for cooling efficiency but obviously corrosion is an issue as is freezing in the winter. In siberia you'd run a higher concentrate of coolant/antifreeze and in Arizona you could run lower, but as is will be a happy medium especially in our temperate climate.

den1 Posted June 24, 2020 Share Posted June 24, 2020 As a matter of interest how many liters is required for a complete change? Quote Link to comment Share on other sites More sharing options...
m12aak Posted June 24, 2020 Share Posted June 24, 2020 (edited) As a matter of interest how many liters is required for a complete change? See this thread here: https://www.mkivsupra.net/vbb/showthread.php?56684-FAQ-Oil-Fluid-Interval-Capacity-Steering-Brake-Coolant-Diff-Engine You'll need a couple of the 5L bottles. If you're doing a complete change, i'd run some deionised water through the system first if the coolant hasn't been changed in a while, mine hadn't for what appeared to be at least a decade so I had to flush it three times!

Boyne Posted June 24, 2020 Author Share Posted June 24, 2020 As a matter of interest how many liters is required for a complete change? Just under 10 liters if you get back car up high when draining. Quote Link to comment Share on other sites More sharing options...

I have 5liters red coolant in rest battery deionised water just temporary in new alloy rad, car is a lot cooler, then I can remember, have the 10liters now so I will drain and fill it with just the coolant so.
