"red or blue coolant" ?

hi ,
i think its probably about time to put some coolant in my 2000 4ltr p38 , i have had conflicting suggestions as to wether i should use the red or the blue and how many ltrs i should put in.

any advice will be much appreciated.

red is the one to use they should be able to tell you in the shop though lol

just ask in halfrauds for antifreeze that is suitable for alloy engines, you will know its right because it's bastard expensive

is it OAT (organic acid technology) on themz?

last time i bought red , it was cheapest to buy volkswagens own , from the vw or audi dealers .

was ages ago though .....

Bluecol used to be the standard in the old Classics and I have always used it, even in my P38,4.6 without any problems. The V8's are all ally blocks and as long as the 50/50 mix is up to strength and soft or better still de-ionised water is used I can't see any reason why it shouldn't be o.k. The Wife's Vectra is a V6 with an ally engine and I use it in that also.
All the manufacturers reccomend their own brand but as far as I know they do not manufacture their own anti-freeze or motor oil. As long as it meets the spec. there is no reason why any brand should not be used as long as it is from a reputable manufacturer.
