Coolant Service

[N9QGS]

Okay, so let me ask this, if the Toyota coolant is good for up to 120,000 miles and I had this impression that at least 100,000 miles. I know there is a lot of people that say Coolant should be done every 30,000 miles maybe on other vehicles, is it the coolant being used then, will the Valvoline require more frequent changes going forward or can I go another 80,000 comfortably with what they use or is that a question to ask them, even though they are in it to make money.

Well if the factory pink coolant in your vehicle may be good to 120,000 miles, but the replacement pink coolant will not have a service life of another 120,000 miles (it will be less). Take a look at the service schedule in the manual.

So if you replace the Toyota pink coolant with some other stuff (Valvoline), the service life of the coolant will be further reduced from Toyota's recommendation, as I'm sure that Valvoline recommends a shorter service life. This is assuming that the Valvoline stuff is chemically compatible with the Yaris.

I would buy two gallons of the premixed pink stuff from Toyota and have the shop use that. An even better plan is to just do it yourself, as the shop will probably just drain the radiator and then just fill it back up.

This is what Toyota actually says about the coolant...

"Initial replacement at 100,000 miles/120 months. Replace every 50,000 miles/60 months thereafter."
I also dug this up...
"Toyota is equipped with Genuine Toyota Super Long-Life Coolant. The replacement intervals for engine coolant recommended in this booklet are based on replacement with Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate, non-amine, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e. a combination of low phosphates and organic acid). If another type of ethylene-glycol coolant is used, replacement intervals may be different."

I take back what I said about the shop only doing a radiator drain a fill since they told you to bring in 6 to 7 gallons. I would still do it myself... and if the shop ends up doing it, make sure you watch them.
