The replacement of the Dodge Timing Belt is scheduled by mileage and not after being inspected like most other engine polymer components on your vehicle. The place on the schedule for the replacement of the timing belt on your Dodge is after the motor has 100,000 miles accumulated on it.
The logic behind not inspecting the timing belt like the drive belts are inspected is mainly due to access to this engine component. While the drive belts can easily be seen when the hood is lifted on your Dodge, the timing belt is behind a metal cover on the engine block. This prevents a quick visual inspection of this engine component but also protects the polymer from the environmental conditions the drive belts are exposed too.
Because of all the components in front of the Dodge time belt and its cover have to be removed, this engine component has been tested to function until 100,000 miles before it should be replaced. After this point the belt tensioner will no longer be able to compensate for the expansion of the belt and it will eventually jump a tooth on either the cam shaft gear or the one on the cranks shaft. This will throw the timing of your engine off causing severe damage to the inner components. The most common type of damage is when a valve comes in contact with a piston because of the timing being off.
The process of replacing the timing belt on your Dodge requires no special tools. Before the old one is removed, the engine should be placed at top dead center. This can be noticed by the markings on the two gears which are what the belt connects.
