A belt tension gauge does not give an accurate measure of belt tension when using an automatic spring tensioner.

Measure tensioner spring tension using a torque wrench and the following steps:

  1. Release tension on belt using a long-handle 1/2 inch breaker bar in tension arm. Remove belt from pulleys.

  2. Release tension on tension arm and remove breaker bar.

  3. Put a mark (A) on swing arm of tensioner as shown.

  4. Measure 21 mm (0.83 in.) from mark (A) and put a mark (B) on tensioner mounting base.

  5. Couple a torque wrench to hole (C) and turn rocker arm until marks (A) and (B) are aligned.

  6. Record torque wrench measurement and compare with specification. Replace tensioner assembly as required.
