After visually inspecting the belt, the pressure must be checked.
Belt Stress
You need to use a belt rigidity gauge to check for proper rigidity. Nonetheless, in most eventualities, you would not need to. A belt must solely have the power to flip roughly 90 ranges on the loosest degree. A belt can have a faulty automated tensioner, a misadjusted handbook tensioner, or be worn. If the belt cannot be adjusted to the fitting rigidity specification with a handbook tensioner, the belt ought to be modified. If the belt is found to be too unfastened with a accurately functioning automated tensioner, the belt must be modified.
Normally, a faulty tensioner will ‘click on on’ or ‘slap’ whereas the engine is working.
Belt Inspection Instrument
The utilization of a belt inspection instrument is an environment friendly strategy to look at a belt. These devices are generally provided at components outlets and by means of on-line promos with out spending a dime.

- Place the socket or belt tensioner instrument on the pressure bolt.
- Press or pull the tensioner inside the fitting course to loosen the belt.
- Take away the belt.
- Arrange the model new belt using the correct routing.
- Take away rigidity to put the belt over all the pulleys.
Belt Various Concepts
- Always verify the correct belt routing.
- Place the belt on the ‘smallest’ pulley ultimate.
- Take away the doorway wheel that allows entry to the belt, when potential. This allows you to be sure the belt routing and positioning on the crankshaft pulley. (this solely applies to transversely-mounted engines)
- Restore fluid leaks.
- Some belts are ‘stretch to swimsuit’ and so they do not have a tensioner. As quickly as they alter into unfastened, they require substitute.
How Quite a bit Does it Worth To Change A Serpentine Belt?
The substitute worth for a drive belt or serpentine belt is usually not too expensive. RepairPal estimates a serpentine belt substitute will worth between $110 and $150. A drive belt or serpentine belt substitute can go proper right down to spherical $50 if you happen to occur to do the restore your self. We moreover found the following estimates for an entire serpentine belt substitute (along with labor) for quite a few widespread fashions, along with the Ford F-150:
| Model | Worth |
|---|---|
| Toyota Corolla | $80 – $105 |
| Honda Civic | $105 – $130 |
| Ford F-150 | $85 – $110 |
| BMW X3 | $110 – $140 |
