CO-LS400

I need to add a little coolant to my LS400, I leaked a little when I removed the hose to change my serpentine belt.

I went to Pep Boys and all they had was the "Green" prestone antifreeze.
What is the name of this "Red" Coolant and who carries besides the Lexus dealer?? What company makes it and who sells it?

Thanks!!

You can get it from the Toyota Dealer or Lexus. I wouldn't put anything else in or you could have a problem.

I agree with Max707, stick with the red Lexus coolent.

Don't touch that green stuff. If it it gets mixed in with the red you can get literally get something that looks like jello.

If you need a good cooling additive to go with the Toyota Red Coolant (same as Lexus stuff) try a bottle of Redline WaterWetter.

Only use Toyota engine anti freeze! And the water wetter stuff works really well especially if your running a water to air intercooler

NEVER, EVER use Dex-Cool based "universal" coolants like Prestone in a Toyota or Lexus product - they belong only in GM and VW products. Dex-Cool and its clones use a chemical called 2-EHA that can soften and weaken plastics and polymers used in cooling systems - no wonder why GM and VW are having coolant issues.

My cousin actually uses the Toyota Red in his Golf VR6, since he had prior issues as you described.

Thanks a million fella's --
I'll be stopping by the dealer next week!

You can also change over entirely to good ol' green fluid...

it will not cause harm to your cooling system, and will not cause any issues...

I use 25% green coolant / 75% dist water, and a bottle of water wetter...

I might be convinced to change if someone could find some hardcore reasoning why, but I just read a maintenance handbook that dispelled all the "myths" between the different colors... basically it said if you have a GM, use dexcool only while under warranty, and to change it to green as soon as you hit the warranty exp mark because of the softening properties... toyota red and dexcool both are more environmentally safe than green, but other than that, not a lot of protection differences....

Cody, I went to the Pink extended interval stuff that is used in the 2004 and newer LC/LX's when I had the timing belt and water pump changed on my 99 Landcruiser. I think the problem is not getting out all the old antifreeze and then having some kind of mix going. When I was looking at antifreeze for my 99 it gets really confusing. For my 2004 I will always use the Lexus extended
interval pink antifreeze.

Definitely low maintenance there...

I agree though... whenever changing radiator fluid, and even when not, but at its scheduled intervals, a proper radiator flush is imperative in terms of maintenance... I see sooo many blown radiators, water pumps, hoses, etc. and I attribute a lot of it to lack of maintenance... Antifreeze breaks down over time just like oil does...

I read somewhere that Toyota rad fluid is chemically different from the universal green stuff, something to do with the materials Toyota uses in it's engines. After all is said and done it's a personal choice.

it is very chemically different... it is less or even non-toxic, whereas green is very toxic... they both do the same thing though...

Agreed they accomplish the same task,...but I meant how the interact with the metals and non metals in an engine.
