If the transmission Timing Belt Company does not extend beyond its limits, then if your car is equipped with an automatic tensioner, you should focus on it. First of all, start the engine, as much as possible to the auxiliary transmission load (such as lighting, air conditioning, turning the wheel, etc.), and then observe the belt tensioner cantilever; work in the engine at the same time, belt tensioner suspension tube should have a small Of the displacement. If the belt tensioner is cantilevered, close the engine and manually move it within 1/4 inch of the travel of the belt tensioner suspension tube. If the belt tensioner cantilever can not be moved, it indicates that the belt tensioner has failed and should be replaced in time; if the belt tensioner cantilever is displaced by more than 1/4 inch, the spring load is too small to cause the belt to slip, Once again, only replace the belt tensioner.

If the belt is not excessively stretched and the automatic tensioner is in good condition, look at the belt's working surface as smooth as a mirror. This is typical of the belt due to excessive wear caused by the phenomenon of slip in the load, the pulley surface of the paint off is the best proof of slip phenomenon.

If the belt squeak occurs only in wet weather, and belt and pulley surface is relatively smooth. Let's do the same experiment: let the auxiliary system drive the system under load and sprinkle water on the belt with a sprinkler, and replace the belt if it does.

Long screaming or harsh noise

Although the belt pulley surface due to stained with sand and other dirt or used belt reverse installation can also cause the belt to send long screaming or harsh noise, but usually due to the auxiliary mechanism drive device caused by improper assembly.

If the noise occurs in a new car running near, it V Belt China may be due to the original manufacturing plant assembly quality caused by not high. Check the parts you think may cause a malfunction. If the noise occurs on an old car, you should consider whether the accessories of the auxiliary mechanism drive are to be completely replaced. Look closely at components that may have been replaced (such as alternators, power steering pumps, etc.) to see if they are securely installed. Also pay attention to whether the installation process in the gasket or bushing dropped, they may also cause misalignment of the pulley.
