Just curious,

Do you guys purchase the nissan coolant or another brand (please state)? do you follow the 50% coolant 50% distilled water mix?

Thanks

 

I use about 85% H2O, 15% percent coolant, and one bottle Redline Waterwetter. Technically, it cools better than a 50/50 H2O & coolant mixture. I don't have to worry about the water freezing cuz I live in CA & Waterwetter supposedly has anti-rust/anti-corrosion ingredients.

 

The waterwetter looks good. Thanks...

Would this freeze in winter? That might not freeze in CA but what about further north, like Maine or Canada?

 

I'm in ohio and stick with the 50/50 mix.
I use havoline's 5-year/150,000 mile coolant (orange not green).

 

I'd stick with the 50/50 mixture in areas with cold climates. Don't wanna risk anything. Nevertheless, a bottle of Waterwetter wouldn't hurt.

 

I'm not sure how the 85/15 ratio of coolant and water cools better. Most manufacturers recommend a 50/50 mixture here in Canada and this also prevents the coolant from getting too thick and not flowing well in the newer engines when it gets cold. Upto about 70/30 coolant/water is about as far as I would go and this tends to have a lower freezing point (depressed freezing point in chemistry), but a slight worse (lower) boiling point. Having a low ratio of coolant may not provide enough of the corrosion inhibitors that the coolant should provide in new aluminum component engines; using distilled and deminineralized water also helps prevent scale build up in our higher compression/hotter engines.

 

H20 is a far better cooling medium than coolant. Actually, a lot of people who go road racing use all H20.

Manufacturers recommend the 50/50 mixture because cars are sold in all areas with all different kinds of climate; the 50/50 mixture will work in the Sierra Mts as well as in the desert with no problems.

Like I said, I don't have to worry about freezing point because I live in SF where it never freezes nor will I drive to the mountains. And like I said, Redline Waterwetter has rust & corrosion inhibitors. Some may be wary, but I for one trust Redline products.

 

I believe I have 75% watter and 25% coolant with a bottle of Redline Waterwetter. Turbo95Max tried convincing me to use all water but I didn't want to.

 

I'm not saying this will happen with water but can't you cool your engine to much?

I know race cars cover portions of the radiator with tape to increase the water temp if it is running to cool.

Something about an optimal temp.....
