If you are curious, it's probably okay to taste a drop and then wash your mouth since it's well below a lethal dose (per this video). It tastes sweet, but causes kidney failure. The antifreeze in your car's coolant mix is not good for environment, humans, or animals. The actual drain plugs take a while to find, but once you have zero'd in on them, this step is cake.

Decreased freezing point, increased boiling point.

Similarly, if the water boils, it increases pressure in the system, which pops your radiator cap, which means you lose coolant, and then with no coolant your engine overheats.

If you live somewhere where temperatures go below freezing point, this is a bad idea since it water expands when it freezes, and can damage things.

Coolant only works in your system if it's liquid.

It's cheaper and easier! With a catch.

It's less viscous, so it's more efficient to pump around your system.

It has a higher specific heat capacity than ethylene glycol.

Water is actually a more effective coolant.

If you factor in time, then just buy premix online.

It seems they are all within $10 after you account for mixing. Here are some non-Toyota options I found: I also bought DI water, and did the mixing myself.

The owner's manual also states that if you use another brand of coolant, make sure it's 'high quality ethylene glycol based non−silicate, non−amine, non−nitrite, and non−borate coolant with long−life'Īs I was a good boy, I bought 1-gal Toyota full strength (aka not pre-mix) coolant from a local dealer for $39. USA (aka warm weather) requirements: premix.See the attached images for how this was done. I had to disassemble and 'calibrate' the Bourdon tube inside by squeezing a pinch point. Note: I found it's vacuum gauge was not zero'd properly. I decided to buy a vacuum kit to help purge out my coolant system.

The way professional mechanics avoid these problems is by pulling vacuum in the coolant system, and then refilling the system with a 3-way valve. These areas become hot spots and can result in damage to the engine. One thing I learned is that if air bubbles get into coolant system, they can become trapped, and prevent coolant flow in that area. also has some great schematics for finding part numbers Understand how your car's cooling system works. I hit my owner's manual ( Pub # OM42672U) I found some good videos on 2008 RAV4 coolant swaps: I just don't see anything beyond internet prattle showing proof of any issues with pink SLL.To start out, I went to Google for a crash course. Greater than 50% not much of an issue though in the States.Īll that said, should use what you want. That's true of any concentrate, and as shown in the link below there are other full strength extended service interval options, beyond the shorter interval Red LL. It is true that LL being a concentrate can be used to increase the AF concentration beyond 50%, if needed. SLL pink on subsequent d&f is 5yr/50k miles. Any Toyota owners manual that originally spec'd the shorter interval Red LL will confirm that. The same poster that commented in this thread.Īnd I realize that service managers are never wrong but LL Red recommended service interval is 2years/30k miles. In rav thread, 'one opinion' with a vague implication of some correlation to pink SLL and the water pump. One must conclude green to be original/convention green which has silicates in it which no Asian manufacturer recommends in/for AF. Got one guy in tundra link says he's a tech and changed his tundra to 'green coolant'. I agree with you, but lots of internet lore/myth in this thread IMO. I don't believe the type of coolant is to blame for anything.
