How to change radiator fluid/ - Toyota Yaris Forums

detroiter · 08-29-2011, 11:28 PM

Well the car is a bit over 110k and I figure it's time to change the radiator fluid, as well as it's starting to get low from evaporating over time ,etc. Is there a writeup or can someone put up a step by step on a proper way to drain the fluid and refill it? Thanks!

Page 8 of the cooling section in the factory repair manual. I change mine at 90k.

That's not a link but it's where to go on this forum. Find that and it will link you to the service manual for the 07. Things haven't changed that much so it should help you out.

Did mine not to long ago. if you have any questions shoot me a PM.

thanks for the info, found what I think I need in the manual. does anybody know, does it matter if I use prestone premix (green) vs toyota super long life fluid (pink) ? - no leaks, levels still ok, color is still bright pink. 152,000km

the new green prestone 50/50 premix that works on ANY car ANY cooling system
(says on bottle) will work fine anywhere Toyota red is specified

otherwise, stick with Toyota red from the dealer and u cannot go wrong

old-school prestone green is NOT recommended

On my ECHO you just opened the radiator drain and take the radiator cap off. Engine is cold! All the coolant the book says is in there came out

Close the drain and fill with 50/50 mix of coolant and water. Start the engine and warm it up until the coolnt level in the radiator goes down. Top up the radiator and rstart. Keep filling it until it doesnt go down anymore.

Yaris is the same?

Doing mine....I drained the
1. Radiator
2. Block via the valve on the backside of the engine
3. Overflow tank on the side of the radiator

Did I get it all?

Nope......Pull the fixture where the bottom radiator hose attaches at the engine behind which is the thermostat. If you easily pry out the thermostat you will see a cavity. That's where the remainder will be.

Anyway I caught the fluid and measured comparing to amount required and I got it all.
