Dex Cool is GM crap...... no, no on anything other than GM I just use the normal green stuff, never had a problem.50/50 is a rip off (compare the per gallon prices)Mix with distilled or RO (reverse osmosis). After cleaning flushes, I run multiple RO flushes (fill, drain, fill,drain..... (about 6)) before the final fill
I know about RO and Distilled. We do both at work. I would love to just run the green stuff in all my rigs. But I own a GM, and 2 Toyotas (my truck & 2006 Scion) and I run the green in the truck, but will the green hurt the newer Toyota engines? Or just run green and call it good. And just change it every year, cause its cheep.
I look at it this way, if I need antifreeze in the middle of nowhere what will be the easiest to find?
Water, LOL
How does water not freeze??
Your scion takes Asian pink antifreeze, Toyota calls it Super long life coolant. It does not have the same chemical makeup as the old green stuff or the Toyota red stuff. Please use the correct antifreeze for the vehicle. Your engines aluminum is not the same as the older vehicles and the head gasket is completely a different design.
I use the walmart brand of coolant. Have yet to have a single problem with it.
Ditto, like several other posters, I much prefer to mix my own with distilled water. Just a habit that carried over from motorbikes. Even if it doesn't help anything, I cannot see it hurting, especially since it's very cheap.I've run peak or prestone for as long as I've been driving toyotas and have never had issue. Usually dump in a bottle of redline water wetter, too.
Is anti-freeze really more expensive than bottled water per gallon? 50/50 may be a great deal when considering the price of bottled water these days...
Distilled water can be found for a dollar or two for a gallon at walmart or other local stores
