Inspect the cooling fan drive belt for reuse. Refer to Procedure 008-002 in Section 8.
Measure the clearance between the tensioner spring case and the tensioner arm to verify tensioner wear-out and
uneven bearing wear. If the clearance at measurement point 5 exceeds 3 mm 10.12 in] at any point, the tensioner
is damaged and must be replaced as a complete assembly.
Tensioners generally show a larger clearance gap near the lower portion of the spring case, resulting in the upper
portion rubbing against the tensioner arm.
1 Tensioner cap
2 Tensioner arm
3 Spring case
4 Tensioner pulley
5 Clearance gap.
NOTE: ALWAYS replace the belt when a tensioner is replaced. However, it is not always necessary to replace
a tensioner when a belt is replaced.
Inspect the tensioner for evidence of the tensioner arm contacting the tensioner cap. If there is evidence of the
two areas making contact, the pivot tube bushing has failed and the tensioner must be replaced.
