Engine Mechanical - 3.0L Duratec (4V): Other Mazda Tribute I facelift

Belt Tensioner - Mechanical

The only mechanical check that needs to be made is a check for tensioner stick, grab or bind.

1. Remove the belt in the area of the tensioner.
2. Rotate the tensioner from its relaxed position through its full stroke and back to the relaxed position to make sure there is no stick, grab or bind and to make sure that there is tension on the belt tensioner spring.
3. If the tensioner meets the above criteria, proceed to test the tensioner dynamically. If the tensioner does not meet the above criteria, install a new tensioner. Refer to «ACCESSORY DRIVE BELT TENSIONER - 3.0L DURATEC (4V)»(ref-178637-S39658822142005061800000) . Belt Tensioner - Dynamic The belt tensioner can be checked dynamically as follows
4. With the engine running, observe the belt tensioner movement. The belt tensioner should move (respond) when the A/C clutch cycles (if equipped), or when the engine is accelerated rapidly. If the belt tensioner movement is constant without A/C clutch cycling or acceleration, a pulley or shaft is probably bent or a pulley is out of round. In rare cases, excessive drive belt rideout (uneven depth of grooves in drive belt) can cause excessive drive belt tensioner movement. This condition can be checked by installing a new drive belt, and repeating the observation.
5. With the engine off, check routing of the drive belt. Refer to «ACCESSORY DRIVE»(ref-178637-S22652259152005061800000) .
6. Inspect the belt tensioner wear indicator to confirm the drive belt is within operating range. Install a new drive belt if necessary. Refer to «ACCESSORY DRIVE BELT - 3.0L DURATEC (4V)»(ref-178637-S17551311432005061800000) .
