I got some Silicone Radiator hoses & was thinking that I should upgrade the coolant. So I need some opinions. I've looked at Prestone 50/50 (prediluted) & Redline Oil's WaterWetter. the Prestone is the normal kinda setup, but FLA gets hot. The WaterWetter package says that it works better without Glycol, So what do you think??

Thanks.

 

I would stick with the good old 50/50 mix.

I personally wouldn't want anything else in there just incase something goes wrong and my warrenty gets voided for using something else.

That's just me though.

 

Warrenty Schmoranty, I have 42k mi, I don't have one.

Thanks anyways.

 

80 water/20 coolant with water wetter

You still need some coolant for lubrication. The water wetter merely breaks up the surface tension and allows for better heat dissapation.

 

OK, thanks. I was looking for one or the other. I read that The redline stuff doesn't like Glycol, but I'll go for it & see.

 

After watching this

http://www.redlineoil.com/products_c...coolantFlash=1

I've decided to go with the Water &WaterWetter only, no Glycol. The Redline page says that is does everything that the glycol does & more, so I'll do that.

 

Sounds good if you live in an area that never gets cold.
A little to much work to change summer/winter,And what would be the long term effect of going back and forth, It cant be good on gasgets and seals.

Yeah, Floriduh never gets below like 50s

 

you should check out Royal Purple too www.synerlec.com

 

too bad I bought the Redline stuff already. LOL they're going in tomorrow.

 

The big issue is corrosion control. Each manuafacturer recommends a coolant with a chemical composition designed to suppress the corrosion of the particular metals used in their engine. If this coolant is not used, or is mixed with another, the "long life" feature is compromised and conventional bi-annual changes may be needed. Here are what the manuals say:

Maintenance Guide, Page 16:
100,000 mies ofr 120 months. Replace engine coolant.

Maintenance Guide, Page 21:
Engine Coolant Drain and flush the cooling system and refill with an ethylene-glycol type coolant....
Note: Your Scion is equipped with Genuine Toyota Super Long-Life Coolant. The replacement intervals for engine coolant recommended in this booklet are based on replacement with Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate, non-amine, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). If another type of ethylene-glycol coolant is used, replacement intervals may be different.

Owners Manual, Section 7-2, Page 196:
Coolant type selection
Use of improper coolants may damage your engine cooling system. Only use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non- silicate, non- amine, non- nitrite, and non- borate coolant with long- life hybrid organic acid technology. (Coolant with long- life hybrid organic acid technology is a combination of low phosphates and organic acids.)
"Toyota Super Long Life Coolant" is a mixture of 50% coolant and 50% deionized water. This coolant provides protection down to about –35 C (–31 F).
NOTICE
Do not use plain water alone.
Scion recommends "Toyota Super Long Life Coolant", which has been tested to ensure that it will not cause corrosion nor result in malfunction of your engine coolant system with proper usage. "Toyota Super Long Life Coolant" is formulated with long- life hybrid organic acid technology and has been specifically designed to avoid engine cooling system malfunction on Scion vehicles.

 

Beat me to it

 

Yeah, there is no way I'd only run water. I loaned my beater truck to my brother in law for about 6 months. He blew a hose and refilled the everything with just water in the spring. I got the truck back about a month ago. Every freeze plug in the engine was rusted to tissue paper thin.

We had to pull the engine and replace all of them. Cost about 1600 in just labor. Ended up replaceing everything in the coolant system as a safe guard due to the amount of junk and gunk floating in the Coolant.

 

o town doesn't freeze normally but as stated above our cars need some coolent and be sure you use ready mix or be really sure that the water you use is deionized

 

well, I'm sure that there will be no issues with this stuff, I might eventually replace it & got back to the OEM, but the stuff that came out looked almost exactly like the stuff I was about to put in, IMO they are the same (or very very very close).

 

Ya! Coagulated blood and ketchup look almost exactly like the same stuff, but I only want one on my burger. Toyota has that type of coolant in there for a reason. If you choose to deviate from that, there may be consequences. Just make sure you're prepared to deal with them.

 

I live in PA so I need antifrezze, I run 50/50 with water weter! I love Redline Products!

 

Any more updates on this???

On my '94 honda cbr f2 motorcycle which I still use, I've had distilled water and Waterwetter ONLY in the radiator for the last ten years, no problem, never overheated!

 

im running with water wetter and have been ever since i installed the turbo. The stuff really works, it brought my temperature down by 15 degrees. It REALLY helps on scorching summer day when the air temp hits about 90 degrees...
