coolant colour

[Knight Rider]

After parking the c70 up and losing all the coolant - cracked hose, no headgasket thank god!! Had to top up with water, now im pretty sure the coolant that was in it previously was blue - can i just pick up any coolant or does it have to be volvo specific?

[foammanmark]

I have to top up my C70 but haven't done a full coolant change, but I just use any decent make of blue stuff watered down a bit.

blue in mine and not the volvo one.....

[JUDGENINJA]

I have pink!! Don't worry about the make, just get the concentration right according to the instructions as you can buy super concentrated stuff.. A hygrometer is a handy tool to have to check your concentration.

Mine is green was changed by volvo at service
I know that you should not mix different types of coolant there are two main types which should not be mixed.

Mine is green also , changed recently at Volvo Specialist

I used blue from Euro car parts.

you should not mix the red with the blue. ( thats the generall answer from garages ! )
one is for older engines - blue
the other is for newer engines and aluminium type based.
i never bothered with that.
my garage said the same.
it is sometimes the problem - the will not mix up together - but in generall they do the same job and can be used together.
if you want to make a full coolant change use only one type.
high performance engines, turbo, intercooler and fully tunned up may better of with red / pink.


personnaly - i used blue in every engine, for a start is cheaper and you get better deals in car shops usualy, unless it is winter time.
never had problems, neither in volvos, bmws, mercs, audis, etc. even in the workvan ( 2 years old - came with red fluid and topt it with blue )

green is mainly used by garages but the most expensive stuff. there is some coolant and also radiator leak prevention in it.
honestly, i think most cars older then 5 years allready have some radiator leak stopp fluid mixed in it.
people use this because is cheaper as replacing pipes or even radiators when they have a small leak somewhere.

hope this helps.

As a general rule green and blue are fine together but don't mix well with red (it won't explode or anything !). Red stuff tends to resist aluminium oxide corrosion more effectively and often are longer life. I run red in mine after the engine rebuild but only because it's an alloy lump and I could get it cheaply through work, as long as the strengths good either will be fine.

Checked and topped up mine today, I have the Red stuff, run it in the Volvo and VAG, both have turbo's

[JamesT5]

I used the genuine Volvo stuff as it worked out about the same price as buying some from Halfords. The Volvo stuff you mix 50/50 with council pop and you'll need 2 litres of the coolant and about another 2 litres of council pop.

Hope that helps.

Yep green is the stuff to use. I get it for free from work :smile:
You can use any just dont mix the colours.
