2003 Toyota Tacoma • 4 cylinder 2WD Manual • 50,000 miles


Have I been riped off?

About a month and a half ago I took my 2003 Toyota Tacoma with about 50,000 miles on it in for an oil change and radiator flush at a local repair station. Until then I have always done my own oil changes. The price and convenience of the repair shop convinced me to give it a try.

While they were testing the radiator after the flush they came across a problem. It seems that the fan was not working correctly and they replaced the Fan Clutch Water Pump Fan Coupling, Shimahide part number is 1604-66709. According to them the thermostat was also defective. They said the fan was not spinning fast enough to cool, and I did not notice this because of the defective thermostat.

I am not a mechanic but I question this. I drive my truck about 60 miles a day commuting to work and the temp has always been fine. The week before I drove 300 miles up to NY with out any temperature issues. I check my gages often when I drive. If is my understanding that if the thermostat is not working than the truck will either run hot and overheat or it will take a long time to get up to operating temperature. Neither of these were symptoms I noticed. The truck was running fine.

After the repairs my truck seems to be running fine except that it is much louder now. There is a roar that sounds like the engine is over-reving. It diminishes when I shift, the truck is a standard. The noise comes about 5 mph before the recommended gear change speed. It is recommended that I shift to 3rd gear at 25 mph and this sound becomes very noticable at 20 mph. When I shift it quiets down and then build up as my speed increases. Driving along at 55-60 mph in 5th gear the noise inside the cab is much louder than it used to be. On top of this my gas mileage seems to have dropped by 10% since this repair.

I had the old part returned to me. It does not look like it but I would like to know if there is any way to bench test this part and to see if this mechanic took advantage of me?

This is one of the reasons that I recommend factory parts, It sounds like the fan clutch is staying engaged. This will definitely give you a roaring sound, and will definnitely cause the fuel economy to be lower.

Did ya solve it? Did ya put old fan back on or replace defective 1?
