Green is the old school antifreeze.

Pink/Orange/red is more aluminum freindly type anti freeze. Anti corrosive to aluminum engine/radiator parts.

If you change coolant, refill with the same color as what came out of the rig, their not compatible.

As far as Toyota is concerned, you can mix the red/pink with the green stuff. But it does make the coolant look like it's dirty/rusty, so stick with one or the other.
If you have a GM vehicle, DO NOT mix anything with the orange coolant. Don't know about any other makes.

I am pretty sure Toyota uses the red or pink coolant (whatever colour it is) because it reduces or prevents electrolysis between the different metals. I would stick with the Toyota or similar stuff, and try not to mix.

They do use the red stuff iirc from the factory and at the shop at the dealers. I dunno I just stick with what color comes out, but the plain jane green stuff hasnt failed me yet inother cars.

Hmmm.

The orange colored coolant specified for use in GM vehicles is DexCool. It is not compatible with other coolants. Mixing the two will cause a sediment fallout problem that can lead to problems.

There are new green-colored coolants available which advertise compatibility with ALL other coolants. These have a different formulation which eliminates the fallout problem.

The DexCool is blamed for intake manifold gasket failure on 1995 to 2001 GM vehicles (give or take a year). It was corrosive to the paper in the gaskets, causing nearly universal failure. Read all about it at fullsizechevy.com.

GM avoided a recall somehow (collusion most likely), and newer GM vehicles have multi-layer plastic/rubber/metal gaskets which are immune to the stuff. I just replaced the intake manifold gasket on my 96 Yukon for this reason. I used a Felpro gasket, it was the new multi-layer variety.

It's quite common among GM owners to flush and fill with old-style green stuff - ethylene glycol. I did.

The only benefit of Dexcool was that it was formulated to protect against corrosion for 100,000 miles. It's downside was incompatibility with other coolants, its higher price, and its corrosive action against paper gaskets.

The 4runner is just fine on ethylene glycol.

I've seen pink coolant; I think it was formulated to taste bad so pets won't lick it off the ground and die. I beleive it's compatible with old and new green colored formulations.

Pink coolant it actualy not compatable at all.

A buddy of mine mixed it with the green stuff and it turned into jello.

I bought Toyota-specific coolant from NAPA; it is kind of a gold color.

1. Toyota coolant is specific to Toyota.
2. There is no off the shelf coolant that is the same as Toyota, which does not have any silcates in it, and uses a proprietary Hybrid Organic Acid Technology (HOAT). Trying to decide what is in Toyota coolant is the subject of many dead horse beatings.
3. Color has nothing to do with the chemical makeup of any coolant.
4. Buy Toyota coolant at the dealer (spit), it will cost about $20 a gallon for 100%. Sometimes it is just better to pay up, and this is one of them.
5. There is no such thing as universal coolant, because there are widely different chemistries used.
6. Just because a coolant has not ruined your cooling system outright does not make it correct.

My $.02, let the comments flow.

that is totally incorrect. toyota does not say you can mix the red with the green. you can mix the red with the pink but you have to use the reds service intervals. mixing the green is very bad unless it is a emergency as it turns to jelly as stated above. if you do this i would totally flush it out as soon as possible.
