Look at the ribs on the inside of the belt, if they are cracked or missing small chunks then replace as soon as possible. I usually replace mine every 2 - 3 years.
Check the fan belt it may be tight when cold and causes the whistle until it loosends up when it warms up during use. Can also be caused by the throttle body needing to be cleaned, carbon build up on the IAC motor
under the alternator you will see a automatic belt tensioner you use a extra long 3/8 inch square breaker bar or a 3/8 ratchet wrench with a pipe extension the pulley is spring loaded so pull until belt loosens and pulls off do the same to put back on make sure there is a belt diagram on water pump pulley cover before you go nuts trying to figure out where belt goes make sure belt is on every pulley groove or belt will chew up and fly off
Normaly there is 10 to 15 time he can survive if continuesly. otherwise it will last for long period as he wish.
There is a tension pulley to the left of the alternator. Put a 19mm socket with a torque wrench on the pulley nut. Turn the nut in a counter-clockwise direction. This will lift the pulley away from the belt and allow you to slip it off. Install is the reverse of removal.
If you have a Toyota only 40,000 miles!
How long will it take to replace a belt tensioner unit and serpentine belt in a lexus 1996 sc300?
Yes, as long as there is no damage to it
The serpentine belt is a long belt on the front of the engine. The belt goes over a number of pulleys and powers many things such as the alternator and power steering all at once. The twisting and turning through all of the pulleys like a snake is how it came to be called a serpentine belt.
Depending on quality it can last 5 years and more, but it's not guaranteed because the life span depends on in which conditions you usually drive.
About 20 minutes
get someone that knows what they are doing, to replace it the 2 long front engine mount bolts need to be removed to replace serpentine belt
Life expentancy would be determined by the vehicle maintenance process. A well maintained vehicle may expect the belt to last 60,000 - 100,000. Periodic inspections for cracks will prevent further damage if replaced once found to be in such condition.
normally between 80 and 100.000 ks
Just check every oil flush your serpentine. It could last a long time...and a short time. It depends on a lot of points: wheater, serpentine quality, bearings... When serpentine is about to fail, or, if it seems to be cracked, scratched or any other ...ed, just change it. The answer above is not from a supervisor or team member and should be disregarded. The correct answer would be 35,000 to 40,000 miles. Rule of thumb is 3 cracks per square inch.
That depends on the vehicle. IF the belt runs the water pump an alternator, you won't be driving very long.
not technically. The serpentine drives the pulleys under the hood. The fuel gauge's float is located in the fuel tank. So no, but if the serpentine belt is off long enough it could affect it if the battery level got too low. But the car will die long before that happens.
