I have paid for a new radiator for my vs,my Ellery`s manual tells me how to take out and put in the new radiator.It doesnt tell me how to put the new coolant in,and how to bleed it.I was told to use tectaloy xtra gold cooling system treatment(coolant mix)...it does 15 litres.I also dont know what coolant was used be before.So can anyone please give me some advice on how to put the new coolant in,And if its good coolant im using...Cheers HK-VS.
