make them correct this and then don't go back...that's Canadian tire for you. leave 1/2 the old coolant in the system, don't clean the reservoir and then improperly fill the system. How much coolant did you get billed for?
F#$k...before going there, a job interview with the tech is needed to determine if you should let him work on your car.
their line of economy parts I would only use on a car i'm selling. any tire with their name on it can't be driven over 60mph due to radial force variation.
