Change Engine Coolant

[YarisSedan]

Coolant on our vehicles are designed for 100k for the first change and 50k every change afterwards. You need to make sure you purchase toyota only coolant as it is specifically designed for our cars and radiators. You also need to premix it with a 50/50 of distilled water.

Draining from the peakcock valve on the radiator will only get approx half of the coolant out of the motor as some is going to be left in the hoses and engine block. Proper way to be using a coolant flush machine that gets all the coolant out and puts all new coolant in. Something that any service shop can do.

Just a FYI here. On my ECHO I used to change the coolant by using only the radiator drain. I measured the ammount that came out and it was what the book said was in there. Probably.....the Yaris is the same. In any event do not make a habit of letting others (especially the dealer!) work on your car. IQs have dropped sharply in the country in the paast few years. All they know is how the screw it up nowadays.

...provided that they have their tank full of pink fluid, otherwise they'll probably consider the *global* coolant as the only coolant you should use.

OT, but that reminds me of the three stages of men. Young men have a petcock. As time goes by, it turns into a draincock. (I suppose that could also be called a peacock. Think phonetically.) With old age, it becomes a stopcock.
