What do you guys think of Toyota's "specially" formulated red coolant? Is anyone using it? I've always run the green stuff, just curious.

From the first couple of replies, it looks like this is the way to go. Do you think I will still reap the benefits of the Red, if I've been running the green for so long? I plan on draining the green and refilling w/ 50-50 Red and distilled water.

It is the only thing I use. My neighbor is a Toyota Tech and he highly recommends it.:rasta:

It is the only thing I usein my yotas. My friend is a Toyota Tech and he highly recommends it.

Something to do with electrolysis of coolant and the corrosion of aluminum. The other thing you need to do is make sure the head is grounded. I run a dedicated ground from the back of the head to the fire wall.

I will use the RED religiously, if you decide to change, make sure you completly flush system before adding red, Toyota strongly recommends you DO NOT MIX ANTI-FREEZE.

Just like the GM Dexcool.....it sucks. I have done more cooling system repairs like waterpumps, headgaskets, intake gaskets, etc in vehicles with red coolant then all the other vehicles combined.

Run the red stuff if you want.....it gives me plenty of business!:D

Whatever, sounds like people that never change their coolant to start with. I've always used it in my Toyotas and one Lexus.

Most longlife coolant is red or at least orangy in colour. Toyota uses it because they want to extend the maintenance schuduel as much as possible in their new cars. There isn't anything special about it, but it does last a long time. I would not use this if I had to buy it because I am always busting into my coolant system while either fixing something or upgrading something. The green cheap stuff is way cheaper. I wouldn't use the red stuff if I didn't get such a damned good deal on it.:flipoff2:

There U go......makes sence for that reason only, use Green, I end up changing mine 2 to 5 times a year because I'm always messing with it. So it's cheaper.;)

Thanks for all the posts guys. It's starting to make sense now :rasta: This is for my dd and I don't think I change it often enough. In this case, I think the red is a good choice.

The red coolant from toyota ,lexus does make a difference, the glycol percentages are different i believe, one of the factory engineers told me what it was but i'm like a siv ,i leak info ..lol

I know it makes a difference if you use an coolant over 50% ,I have noticed that the thin cores toyota use cant dissipate heat as well with a strong mixture of the green prestone stuff and will actually make it overheat, other wise it works. Flushing it with some nuetral agent ,aftermarket flushing cleaners will help before a change.

I have used both, i prefer the red ,i think it was zerex that made it, the key to coolant is acidity,don't let it turn into a battery:nuke: .
As the coolant goes bad ph changes making it basically a battery, and um a battery with an aluminuim head and cast iron block aint good.:eek:

You can use ph sticks or a voltmeter to check ocasionally to keep on top of it.

One note ,I have never had a corrosion or electrolosys problem with the red factory coolant. With the new aluminium composites and better castings corrosion is a lot less.

Hope this helps ya...
