Thread: Coolants

In my 89 3.9 litre, have always used Nulon concentrate (green) mixed one part coolant to two parts demineralised water that you can buy in Woolies. So 33% solution which would cover all but Siberian climates. Search threads for refill procedure which is pretty critical to get all air pockets out - from memory the vehicle needs to be on a slope with nose upwards to ensure all air is expelled. The drain plugs on either side of the block can be a @#$% to remove and good idea to replace them with taps (Atlantic British I think had them). 14 litres the total fill I think so one 5 litre carton of concentrated coolant should do it.
