I workd for a differnt canadiantire in the servie desk. guess what, you are wrong. this is called customer request work, no diagnosis. If you pay for a diangosis, you get it diangnosed and the asurance that a mechanic figured out what was wrong. If you assume you knoww what's wrong and tell them to do something, you asssume the risk that YOU were wrong and pay the bill. ps power steering pumps dont squeel, belts do.
shoulda payed 30 bucks to have a mecanic look at it first. dont blame them becuz you tried to cut a corner and play mecanic yourself
