Hi all,
Before anyone asks, I haave sesrched the subject heading and found lots of good information. But I cant find anything solid from Volvo or any other source that specifies the spec of coolant needed, like they do with motor oil. So that leaves me guessing or relying on coolant manufacturer guides which appear ambiguous.
My plan is to flush the cooling system with demineralised water and replace with a concentrate/water mix. The coolant in there has a light blue colour and I suspect its just been topped up with water over the years.
Castrol and Nulon have recommended coolants but it appears to change between years for the T5 engine. Even the XR5 of the same year has different coolant recommendations for the same engine. Nulon has a particular coolant that they recommend for all cars sold in Australia but Im dubious.
Any help appreciatted.
Reg.
