-----------------------------------------------------------------------Thanks again.
I did called the garage you recommended and they want me bring my car to there for further discusion. I'm going to drop by later.
You're right. Canadian Tire told me nothing except wanted me to do repairng test which will cost $165.
For the codition pass, I called Ontario ministry of Transport and was told that I have to go to the authorized facility other than else garages. the cost maximal is $450.
I carefully read the info provided by ccc. it's really usefully for me. At least I got an idea how the exhaust system works. I'm just wondering if I need change both CATALYTIC Converte as well as sensor because Engine Check is on which is related to the emisson control.
Yes. My car is Nisan Maxima which manufactured by Japan. Nisan's parts too expensive.
Maxima is a VERY nice car. It is same class as Camry V6 or Accord V6.
Honda, Toyota, Nissan, Mazda, Subaru, Susuki, they are all Japanese cars, and are RELIABLE.
If you buy parts from dealer, which are BETTER quantity and also more expensive. You can buy something called AFTER Market, which is like generic drug. And because of the fact that Honda and Toyota are the mostly sold Japanese cars, manufaturers will produce after market parts for these two Japanese companies than other Japanese brand names, (if you are driving cars like Accura, Lexus, .. the expenisve verions of both company, then, don't go for after market), and those parts are usually much cheaper (may be 30 % of that of original).
The cost of repairment has two parts, cost of parts and labour.
If you go to dealer, cost of labour (in this case, change of Converter) is usually 95 CAD an hour plus tax, and the job is 2 to three hours (there is a STANDARD book outlying how many hours of labour for a particular job), hence if you go to dealer to change your converter, just the labour is over 400 CAD. Don't expect Canadian Tire will charge you less!. And the part is more expensive (and of course better quality), you should expect the cost exceeds 700 or even 800, and because of the qulality of original, you can have the car for another 11 years before you need another repairment.
Since you want to use your car for another two years (pass once), cost of after market is around 150 and actual hours of labour is 1.5 hours, and garage usually charges 45 to 50 an hour (CASH, tax included), hence my estimation is around 250. With a little bit of luck, you can pass next time, you can drive car for FOUR years, and at that time, your car is 15 years old, maybe time to buy a new one.
Those who work in Canadian are EMPLOYEEs of Canadian Tire. Canadian Tire as a company must make money, hence will charge according to that STANDARD book. And Canadian Tire pays their own mechanic around 35 an hour, but if you include all the EI, rent, health benefit, pension, etc, the cost to Canadian Tire is at least 65 an hour, and that is the reason why cost of labour there is over 80 an hour. If you go to garage, the mechanics are usually SELF-Employed, and licensed. If you know the mechanic is HONEST, you save most on Labour fee.
By the way, good luck, and enjoy driving your MAXIMA.
