WATCHPOINT: Belt tension gauge: If you replace a
worn or damaged belt, the new belt must be checked for proper tension
as well. Additionally, a new belt loses 60% of its tension in the first hours of
operation. It needs to be tested under heavy load, and then
retensioned. After a new belt is installed, run the engine with every
accessory turned on - for 15 minutes (this puts a heavy load on the
belt). Then check the belt tension again and adjust it as required.
Note that belts on high amperage output alternators may need
retensioning twice after installation. If the vehicle
has a multi belt drive, the belts need to be carefully matched. Then belt tension should be tested every 10,000
miles. CArrying a spare belt is wise. |
