Alright, I have searched a lot of forums and most hits seem to be from british consumers who obviously have a lot of different vendors and nomenclature. I am going to do a coolant drain and fill on a new to me D90 with a 1994 disco 200TDI power plant. I would like to make sure I get the type of coolant correct.
From what I know/heard/read: go with the simple 'green' coolant style - not DexCool, not HOAT, etc. They say the older engine blocks dont like some of the additives, silicates, etc.
So, keeping in mind my 200tdi is from a mid-90s defender, what would you suggest?
Right now I have some extra regular old Prestone concentrate in the garage I was going to mix 50/50 and fill.
Thumbs up? Terrible idea? haha. I know this is a total noob question - but I am a noob when it comes to defenders and I have just read so many seemingly conflicting comments about coolant that it makes my head spin!
