    Hi all,

    2010 prius III, not three since Roman numerals were used for model year 2010.

    After getting a 150k service, all liquids changed. My heater only blows warm air regardless of temp setting. Setting to max heat DOES blow hot air. Ok, changing temperature may alter heat a smidgen but it's warm.

    Looking online, it may be an air bubble in cooling system? They did change the coolant...

    Thoughts?

    Does this mean that the car is not getting to correct temperature?

    Not at all knowledgeable but it seems VERY likely due to that service, and I wouldn't try DIY remedy, just get on the phone to them.

    Geesh, were at 48000 kms, don't think it'll ever get to coolant change..., well it will due to time interval, eventually. ;)

    welcome to priuschat! it means they didn't bleed all the air out of the coolant loop. it's a tricky process, even for some dealers. unfortunately, you'll have to go back. all the best.(y)

    Then why would it work on max? Does the Prius have auxiliary electric heat?
