How do you change the serpentine belt on a 3.7L Jeep Liberty?

Answer 1

CAUTION: Don"t let the tensioner arm snap to the freearm position, it could cause severe damage to the tensioner.

Belt tension is not adjustable. Belt adjustment is maintained by an automatic ( spring load ) belt tensioner.

REMOVAL:

(1) Disconnect negative battery cable from battery.

(2) Rotate belt tensioner until it contacts its stop.

Remove belt, then slowly rotate the tensioner into the freearm position.

INSTALLATION:

(1) Check condition of all pulleys.

CAUTION: When installing the serpentine accessory

drive belt, the belt MUST be routed correctly. If not,

the engine may overheat due to the water pump

rotating in the wrong direction.

(2) Install new belt. Route the belt around

all pulleys except the idler pulley. Rotate the ten-

sioner arm until it contacts its stop position. Route

he belt around the idler and slowly let the tensioner

rotate into the belt. Make sure the belt is seated onto

all pulleys.

(3) With the drive belt installed, inspect the belt

wear indicator. On 3.7L Engines the gap

between the tang and the housing stop ( measure-

ment A ) must not exceed 24 mm (.94 inches).
