Going to add water wetter/purple ice... a few quick questions>>>

[01northernS4]

1. Can I just drain the stock combined audi antifreeze reservoir (blue cap) in the engine and top up with a bottle of water wetter/purple ice, will it mix properly eventually, if not what is recommended?
2. What is better, water wetter or purple ice, does it matter?
3. How many bottles should I add, is draining the reservoir and filling with water wetter/purple ice enough?
4. Can I actually notice a reduction of up to approx. 14C/22F in fluid temps they advertise? I'm guessing nothing near that but what have you all seen generally, 5c/10F? It all helps in the end...

BTW, I have stock audi mix 50/50 antifreeze/distilled water.

Thanks!

My tech uses Redline water water, not the purple your talking about it does help I doubt as much as advertised.

I suggest just adding a bottle of the regular pink water wetter since our coolant is pink imo works well with Audi coolant system.

Also just read royal purple may mix better with our antifreeze... but apparently most of the benefits come from just mixing with water...

Will I see any benefit from mixing with our stock 50/50 antifreeze/water?

Thanks again

There were some issues with Water Wetter gunking when mixed with AF on some older platforms so I went with Purple Ice as its a newer product (straight water/Purple Ice for my s/c loop). However, plenty use Water Wetter when running lower AF ratios and it seems to be ok.

I don't know whether I'd add it to a 50/50 mix as I doubt it'll make much of a difference but to each their own.

Got it... so if I were to add it, I could do so by emptying the reservoir and topping up with a bottle of the preferred royal purple ice and it should mix itself with the rest of the coolant/water in the system

Has anybody else added it to a 50/50 stock coolant mix? At 10 bucks not a big waste if it doesn't work...

Thanks everyone!

No it’s a lot less than a full bottle, but yeah you would just pull some coolant and add the appropriate amount of Purple Ice and it will mix.

thank you sir!



So has anybody else added purple ice/water wetter to a 50/50 stock af coolant water mix and seen any measurable benefits?

This. Just siphon off some coolant mix from the reservoir and add the Water Wetter or Purple Ice. There were some problems with earlier versions of Water Wetter and some Audi coolants. That's all in the rear view mirror, now. Both products are compatible with current coolants. I run Purple Ice, but the two products are basically interchangeable.

One thing: Run as much water as you can. Water is far better than coolant in heat transfer. And the more water the better the water wetter product works (either brand). If you can go 70/30 in favor of water and add the water wetter, then that would be better. 70/30 will protect you to 0 degrees F. 80/20 gets you to +20 F. Unless it gets colder where you are, use as much water as possible.

I don't think hes divorced lol

Wow, that's great info MSq5... thank you... I'm in southern Ontario and we can see -20 to -30C in the winter but I do park in a heated garage... where did you find the references on mix ratio and temps? I may do 60/40... will have to figure it out but hopefully emptying the reservoir and filling it with distilled and half a bottle of royal purple ice are the right ratios... just need to figure out the capacity of the cooling system and the reservoir.

Not divorced but I think a 60/40 will work across the board for me better than stock ratios... I should still see improvements despite not being divorced on a 60/40 mix with royal purple ice?

Thanks!

Good morning everyone!

So a few points:

1. Tested my antifreeze/coolant mix and it's registering off the meter at a freezing point over -45F/-43C and boiling point over 269F/131C... this tells me my mix should be over 50/50 water to coolant... maybe 40/60?
2. As I read the instructions on the royal purple ice bottle it says 1 to 2 oz per quart of coolant/antifreeze mix... our system should hold 12 liters/quarts... it seems I need the whole bottle?
3. Royal Purple Ice bottle says to change every year/30k miles... seems excessive no?

So my plan is to drain the reservoir and top up with a full bottle of royal purple ice and distilled water... drive around a few days to give the fluids time to mix and retest hoping to get to 50/50 or 60/40 water to coolant ratio. This should yield somewhat better cooling.

For those that have done this are you using a full bottle of royal purple ice on our coolant systems (approx. 12 quarts/liter capacity) for the right ratio?

One last question - by draining the reservoir, topping up with distilled and royal purple ice and driving around a few days will my coolant system mix completely so I can retest? I really don't want to flush it all if I don't need to until I get my new heat exchanger.

Thanks!

[01northernS4]

Anyone?

For those of you who have used royal purple ice/water wetter does 1 full bottle to the entire cooling system sound about right?

I just want to get the ratios right.

Thanks again.

[theweebabyseamus]

Yeah if our system really is 12 quarts I would do the whole bottle. 2 oz to quarts is for straight water.

[MSq5]

Just a few thoughts. No expert by any means. Here is what I concluded based on other threads here, the manufacturer's recommendations, and my admittedly recent use of Purple Ice:

1. For the surfactant (Water Wetter or Purple Ice), your water to air ration must be at least 50% water. If your water is only 40%, you need to drain some coolant and replace with distilled water or tap water if your tap water is soft, then add the Purple Ice.

2. I run Purple Ice in a 70/30 water to coolant mix and I just add it to the reservoir.

3. It does wear out over time. The active wetting agent and the anti-corrosion agent have a life of about 30,000 miles. Just repeat the process by draining enough coolant to add another 12 ounce bottle. It does not hurt anything to add more, but adding more does not improve cooling unless the existing Purple Ice is over 30,000 miles.

4. Yes, one 12 ounce bottle should be sufficient for our cooling system volume, even with a larger heat exchanger.. More does not hurt, but offers no increased benefit. The Kenne Bell supercharger folks have a lot to say on the subject and found that with their their blowers on GM V8s, the Lucas version of water wetter dropped IATs by 6 degrees and raised power by 7 whp during dyno pulls.

Just confirmed with Royal Purple help line our system is 12 quarts/liters so 1 full bottle for a 50/50 mix and 2 full bottles for straight water. He said even at 50/50 ratio should see 5 to 10F approx. reduction in temps... won't hurt to try.

He also said the royal purple ice looses it's efficacy so it must be added yearly or every 30k miles.

lol we replied at about the same time... Excellent info right here and big thanks MSq5 for your response... you're right on the money!

Yes. I did revise the post after looking at the Kenne Bell video again. IATs went down 6 degrees and hp went up 7. That was with two bottles of the Lucas version, but they all work the same way. I don't know the coolant capacity on the GM V8 they tested, though.

[TC_S4]

Did anybody tested the IAT before and after using Purple Ice or Water Wetter?

Also I live is Canada, winter can be -40 degree celsius, will that be a problem using Water Wetter or Purple Ice with 50/50 mix?
