Radiator Coolant

[cartm58]

Any Recommendations on coolant for Range Rover 3.9 litre radiator

as in brand name/costs

frequency of changing the radiator contents

topping up the fluid reservoir

Personally I would use the Caltex ELC (Extended Life Coolant) with OAT (Organic Acid Technology) , avaiable in concentrate or pre-mix from Caltex Depots.

The last lot I bought was $135.00 for a 20 ltr drum for the concentrate.

I don't like the pre-mix for complete changeovers as you can't get all the water out after you have flushed..

I do use pre-mix for topping up only.

I change mine every Autumn.
