Coolant differences

[Gabbastard]

Whats the difference between pink and blue coolant?

I remember being told before but I cant remember exactly what it is.

[Cam]

Without being to technical, the colour can be manufacturer specific but using the wrong antifreeze can cause a gas called boron gas which can eroded the joints in some water systems, other antifreeze can cause the aluminium to corrode internally. Nissan have used a "green" antifreeze for years but now new cars at pdi are filled wih "blue" anitfreeze the mix of what do not know!! Nissan/Renault badged vans use a light shade of "orange" to fill their vans, again, I do not know how it is made up. The "blue" antifreeze we all buy from our local spares supplier I believe is "glycol" based and then you have longlife antifreeze too!!
Best idea is to do a search on't internet.

Copyed from a simple search :hug:

[Gabbastard]

So what should be used in a Saxo, the blue shit?

[Dave_P]

Correct.

[Gabbastard]

Pissflaps, I bought Halfords pink stuff. Grim.

[Gandi699]

why cant you use the pink OAT stuff?

[Ross]

You're all fags for running water/antifreeze, regardless of colour :p

[Bedford126]

Ross are you running the none water based liquid?

If so bit of advice I'm wanting for the civic.

[Gandi699]

I saw that stuff on wheeler dealers of all places. He took the cap off when it was hot and it didn't boil over!

That whats I used. The blue stuff I used (cant remember brand) went rusty coloured in no time

Jag use it it some of there cars and its a lot cheaper from them. but apparently it can damage the aluminium heads? and can clog the thermostats up.

Just wanting a bit more info on it before i go and chuck it in.

[Gandi699]

Obviously its boiling temperature must be that much higher than a water mix, hence not needing to be pressurized. Seems like a good idea but I'd imagine it costs a fair bit or as you say, has a downside regarding reactivity with certain metals otherwise most manufacturers would be using it i'd have though

Yeah mate it boils at 180'c degrees and freezes at -40'c so its a good range.

The prep fluid from Evans is £40 and the coolant is £63 per 5 litres. So its a pretty hefty whack of money for coolant.

yes mate - I run Evans 180 in mine.

I haven't needed the flush this time as the engine was bone dry since rebuild. The flush is really recommended though if you're replacing an "active" system as the Evans stuff absorbs water which defeats it's purpose.

It boils at a much higher boiling point, but the clincher for me is zero pressure in the coolant system so less stress on components. Supposedly more power but I guess that's only because it would technically allow more ignition advance.

Thats a fair few coolant flushes with normal stuff and even new thermostats thrown in for good measure. Still though, if you've got a trick engine then worth it

Zero rust. No clogging. Mmmm. No brown sludge ;)

[Bedford126]

Cheers Ross I think I will give it a go in the civic but I will be using the jag stuff as its about half price with work's discount.

I liked the idea of never having to worry about it for the life of the car. as well as no rusting of internal components.

Me too :p There's a lot of benefits tbh. Like I say, the real deal sealer was the lack of pressure in the coolant system. No strain on hoses or clips etc.

Just make sure some muppet doesn't helpfully "top it up" with water ;)

[Gabbastard]

100 quid for coolant, fuuuuuuuck. Sounds good though.

Anyone know what the problem with running OAT coolant (pink stuff) in a Saxo is, will it corrode the aluminium in the head?

[Gandi699]

Yes i'd like to know if there is a problem too. If so that batch of blue coolant I misordered and couldn't return may get used haha

[greyjasper51]

Wetter water :-) or water wetter... What ever it is, it does work i tried it in karting but has to be 100% concentrate, dropped about 10c of the temp... Werent worth the money tho...

[Ross]

I'm ignorant on coolant other than the Evans stuff to be fair - is the colour not manufacturer specific, or is there some "industry norm" for pink = this, and blue = that?

[Gandi699]

I believe the colours dont always depict the mixture/type from what I've read so one manufacturers pink isn't necessarily the same as the next one

[f13sta]

Pink and blue are the same. Just the pink is 5year long life.

Here's an article off our site about coolants that explains most of what you need.

That's not how it's supposed to be used and that does work out expensive. Waterwetter is designed to reduce the surface tension of water (it's a surfactant, like detergent but without the foam), so the water can flow faster through the system, transferring heat away and reducing the temps. Using it neat means you're using too much of it and there isn't enough water in the system for it to do what it's supposed to do. As one bottle is enough to do the cooling system in a Skyline or something like that and give a 15C temp decrease, using it in higher concentrations is pointless.

Am I right to take from that article that the new style antifreeze (what I was referring to as "pink shit") can be used in older engines such as the VTS? Im unsure about the "yellow metals" bit.

Yes it can mate.

Iirc most company's such a halford's only make red/ pink now.

[oilman]

Yes, it's fine to use. There are plenty of blue coolants around still, but generally one of the orange/pink/red ones are the safe option as they meet more manufacturer specifications.

[Gabbastard]

Thats great, thanks for that :)

[Gandi699]

Good news, less work for me to do this weekend and so can drink more beer!

[james230]

is prestone any good for my saxo vtr thanks

this stuff sounds like it could be good for my supercharged track car. whats the downside to it please?

[Bedford126]

Prestone is the yellow stuff iirc. Yes its fine to use as its a universal but its more of a supermarket make and has a supermarket price to go with it. You would be better going to a motor factors and buying from there.

the colour usually denominates the fact that is a type of coolant that does ot need changing every two years -yes use it in anything --50% mix for best antifreeze( -27c at least ) protection 25% still good for (-17c)for best cooling --pure and I mean pure water is the best coolant --but as usual the compromise is anti corrosion =antifreeze qualities
water wetter --no good for road car in freezing conditions+ very little canti corrsive properties

i was under the impression i could just add this to my regular stuff in my car?

Other than being an additional cost, none really.
