Hello all

I've noticed a loud squeaking noise coming from around the generator area
when I started my 2007 Corolla yesterday. After driving a short distance it
stopped. I've also noticed during the last week or so, that the radiator
fan seems to turn on far more often than it did in the past. My car only
has a little over 7000 km so far as I only use it to run errands on my
weekends. Could it be that the water pump is failing already or that the
belts just need adjustment? I'm bringing in the car to the dealer tomorrow
morning and just want to be prepared the best or worst case scenario. I
bought the car exactly 3 years ago next week so problem may or may not be
covered by warranty.

Thanks!

No idea, but if you weren't already planning to, please post the
result later.

If it is in warranty, these are great questions for your dealer's
service department.

My guess is that it is squeaky belts. If you need new belts, that is
probably not covered by warranty because they are considered wear-and-
tear items. You can get them replaced more cheaply elsewhere, although
you may be better off letting the dealrer replace them. There is
probably some warranty on replacement parts. And if there is still a
problem, you can say that the dealer fixed it and is responsible for
backing his repair.

I believe that your Corolla has a serpentine belt, which is 1 long belt for
all of the accessory drive functions like AC, power steering, and alternator
instead of multiple belts.

The tension on a serpentine belt tension is usually maintained with a spring
loaded pulley so there is no adjustment. It is possible that the tensioner
is not maintaining tension, an idler pulley is making noise, the belt is
glazed or damaged, or the bearings for one of the items driven by the belt
are failing.

As for the radiator cooling fan turning on, there are several possible
causes, some normal, some not, like higher ambient air temperature, more
stop-and-go traffic, more AC use, low coolant level, obstruction or damage
to the radiator, weak radiator cap, lean air-fuel mixture, loose connection
with the engine coolant temperature sensor, failing engine coolant
temperature sensor and related circuits, problem with the engine lubrication
system, etc.

When you take the car to the dealership service department, describe the
symptoms and what is happening, and not what you or any of the posters
(including me) here think the cause is. The reason for this is that if you
ask the service department to replace the belt and the cause is something
else, you still have to pay for the work you asked them to do.

Belts indeed are a maintenance item. Proper preventive maintenance requires
that when one belt needs to be replaced, EVERY belt should be replaced as
well. They all have accumulated the same mileage.
