Grand Cherokee 2WD V8-5.2L VIN Y (1998)
Drive Belt: Description and Operation
Accessory Drive Belt Tension
Correct drive belt tension is required to ensure optimum performance of the belt driven engine accessories. If specified tension is not maintained, belt
slippage may cause; engine overheating, lack of power steering assist, loss of air conditioning capacity, reduced generator output rate, and greatly
reduced belt life.
4.0L ENGINE
Belt tension is adjusted at the power steering pump bracket and idler pulley assembly. There are different types of adjustment gauges for checking
either a serpentine or a V-type belt. Use the correct gauge when checking belt tension. Place gauge in the middle of the section of belt being tested
(between two pulleys) to check tension. Do not allow the gauge (or gauge adapter) to contact anything but the belt.
5.2L/5.9L ENGINES
It is not necessary to adjust belt tension on the 5.2L/6.9L engines. These engines are equipped with an automatic belt tensioner. The tensioner
maintains correct belt tension at all times. Due to use of this belt tensioner, do not attempt to use a belt tension gauge on 5.2L/5.9L engines.
