Coolant

[Topaz]

I just bought Nulon Ultra Cool concentrated radiator treatment. Actually is this a proper coolant or did I just buy something useless for my Skyline? lol

I also got the Nulon Radiator Flush and Clean.

Umm, yeah, I bought that and was told its not recomended. I was looking at it in Sprchp today and theres some called 'Tefylon' or something like that and a Castrol branded AntiFreeze/AntiBoil, I'd go for one of them.

Also the concentration level is a recommended minimum (33% means add 1 part AF/AB and 2 parts distilled water) so IMO I would create a mixture of 40-50%.

The flush I guess is fine.

If you buy the concentrate buy the stuff that has the proper glycol content, It should be marked on the bottle that is has 1036gm glycol p/L.

If it isn't that concentrated its watered down (to sell cheap) and makes it harder to mix. (working out the true glycol content you actually have)

If you get the concentrated stuff that is 1036gm/L you mix this at ratio of 33% concentrate to 67%water and its correct.
