What to keep my eye on? Preventative Maintenance

[Shaunous]

Tony the best thread I have ever read.
The age old coolant debate, now what are the recommended or equiv brands that I should use as thats what I am doing this weekend

I'm over in PNG, so I cant get any info on my hands, but Nissan will have a grade that it requires, normally in the form on the make-up (bi-etholene glycol or tri-etholene glycol), and some other minor additives, this will be in the form of a 'lubrication and fluid specifications guideline', again sorry I cant get you that info, it'd be in a shop manual, i'm sure the other guys on here will be able to help you more, or maybe try google. Then when you get the spec's, go through the coolants in the shop and match or better their spec's. Same goes for oils and other fluids.
