if there is not much missing - say less than 1/8 of a gallon, refill with distillate water

I'd recommend to buy just one bottle of red Toyota coolant for top-offs, and when you do your first coolant flush, you can switch to something else.

In my mr2, I use Prestone All Makes/All Models coolant. It is silicate-free, like Toyota coolant, which is the main difference from normal coolant.

The prestone stuff is green though. If you mix red and green you get a nasty brown... Which is why I say to buy a bottle of red stuff for now.


Someone on mr2oc posted this response they got from Toyota regarding coolant choices:
Thank you for contacting Toyota Motor Sales, U.S.A., Inc.

Toyota recommends using Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology. Use of improper coolants may damage your engine cooling system.

In my old Civic, the reservoir tank simply slid off so that you can poor it back into the radiator. But if I were you, I wouldn't screw around, just get the Toyota coolant and fill the thing back up asap. ruining your head gasket cause you want to save $20 is dumb.

You shouldn't have drove it in the first place with low coolant. It's ok to drive with low reservoir, but if it's missing in the radiator, it's a no drive situation. Now, you've probably introduced air into the cooling system and hopefully the Yaris coolant system can do a good job to compensate for that. But from experience with small engines (Honda), it doesn't take much to kill the engine once the coolant gets messed up.

The reservoir 'never' drains to the radiator...when the water gets warm it expands and goes to the res from the radiator, only when the water cools and shrinks does it 'suck the coolant from the res to the radiator. Without water in the radiator you can ruin the engine easily. It may take many cycles for the radiator to 'suck' enough coolant back into it, please put coolant in the radiator----foolish not to.

:clap:

x2...99 cents a gallon...better cooling properties than anti-freeze...just make sure it's "distilled" and not "mineral"...

another idea would be to add a product called Waterwetter. It works by lowering the viscosity of your coolant system which prevents cavitation (bubbles)...It costs about $7-10...

just about any grocery store or Walmart.

Don't dilute your coolant with distilled water if you don't know how much is missing. $20 for a gallon of Toyota coolant vs. $20,000 if you over dilute it and it doesn't maintain it's freeze point next winter. Don't gamble with your new TS, we all want one and would hate to see anything bad happen to it. Are you ready for an oil change? Get a service done at your dealer and they should top all your fluids off. :thumbup:
