V-Belt Tension, Check and Adjust (Vehicles as of MY '95)
 Remove, Disconnect Disconnect ground lead from battery. Remove wiring harness plug from temperature sensor (3) (only C 14 SE). Remove air cleaner housing (1) with air intake hose (2). Remove throttle body on C 14 SE engine - see operation "Throttle Body, Remove and Install". | 
|
Unclip octane number plug from bracket (2). Unclip engine wiring harness from wiring trough (1) and retainer (3)
and lay aside. | 
|
 Measure Measure V-belt tension with Tester KM-128-A. Check area as close to the middle between the two pulleys as possible. Press tester lever until the micro switch pin touches the V-belt (see illus.). When the pin touches the V-belt, a buzzing noise can be heard. | 
|
Read off the value on the scale and multiply by 100 (10). This value corresponds to the V-belt tension in N (Kp).
|
Nominal V-belt tension values: |
|
New |
N (Kp) - 450 (45) |
|
Run-in |
N (Kp) - 250 to 300 (25 to 30) |
 Adjust If nominal V-belt tension values are not reached: Loosen support (1) at alternator and intake manifold. Loosen bolt from alternator shackle (2 + 3). Loosen bolt connection, alternator to alternator bracket (4). Adjust V-belt tension at tensioning bolt (5).
