    I hit 100K miles and got the P1121 error code.

    I wrote up this doc to consolidate all of the info I found on Youtube , Priuschat, and other sites so I would have a single doc to refer to when I was working at my friend's garage to resolve this problem myself vs paying someone else. I wouldn't have internet access at the garage.

    I hope this can act as a reference to others who may need to do the same. Any suggestions or comments are welcome.

    This pdf covers

    Replacing the Coolant Control Valve
    Emptying and Replacing the ICE Coolant incl. bleeding the system
    Removing the driver side headlight
