****en....cut the **** you guys! who gives a **** if he has a side of the story. You left him with your car and PAID him for a service. He is responsible to perform this service via CONTRACT LAW. A reasonable person would expect (see legal studies 101; reasonable person) that by the time their car was returned to the original owner, that this contract would have been Successfully completed.
Sounds to me like he defaulted on the job; and ****ed around with your ride at the same time.
Seeing as the average shop mechanic (He would've advanced to something else if he had a real head on his shoulders)...this "average mechanic" is a ****en loser, thats why he's a mechanic at a shop. If he was a good mechanic, he would be WORKING FOR SOMEONE ELSE. We all know that Heavy Duty mechanics make more money than some shop lackey changing water pumps, go back to the shop when he's there first thing on Friday, and jump so far down his throat he'll be wondering if you jacked off while you were in there!
Tell him that any ****en moron can change a water pump, I did my 2.3L Tempo with no shop manual, no hoist, no nothing...in like an hour and a half. You PAID that stupid **** money to **** your car up, and now you have to get it ALL done again.
SOLUTION: Tell that shop you want
ALL your money back, and you will
RETURN the water pump to them, because now you have to go somewhere else and get another one, in case he cooked that one in you and tried to hide that too.
If he says "no, your not getting any money back"...tell him you want ALL the insurance information from the Garage Auto Policy that his shop must LEGALLY carry, and if he doesn't give it to you then you are going to call the police.
Con of this method: You can never return to this shop, or encounter shop owner in dark back alley
Pro of this method: This shop owner is faced with an altamatim; he can either explain to the police why he refused you contact with his insurance company... or he can refund all your cash.
Trust me, his insurance company will have
NO problem paying the $800.00 it is going to cost in parts and labour to indemnify you for the damage that mechanic is liable for. "Errors & Omissions" is a large section in insurance; leaving a broken bolt in a crucial part of your engine is not something a reasonable mechanic would do.
Im out; this post is getting REALLY long. If you use my method though, you'll get either ALL the money back that you paid this stupid ****er at this shop, OR he (or his insurance company) can pay for you to get an ALL new water pump / upper & lower rad hose / coolant flush / tempurature thingy / lower gasket set & installation.
Think about it; it's the law.
