ON-VEHICLE MAINTENANCE
DEFLECTION CHECKING POINT
05UOBX-03 3 10. Measure the timing belt deflection by applying moderate
pressure (98 N, 10 kg, 22 lb) midway between the two cam-
shaft pulleys.
If the deflection is not correct, repeat from Step 7 above.
Deflection:
9.0-11.5mm (0.35-0.45 in) at 98 N (10 kg, 22 lb)
Harness
1. Connect the harness connectors. (Refer to page 82-l 8.)
Hose
1. Connect the hoses. (Refer to page 82-17.)
03UOB2-035
Accelerator cable
1. Install the accelerator cable.
2. Check the accelerator cable deflection.
If the deflection is not correct, adjust by turning nut A.
Deflection: l-3mm (0.04-0.12 In)
Steps After Installation
1. Fill the radiator with the specified amount and type of engine coolant. (Refer to Section E.)
2. Connect the negative battery cable.
3. Start the engine and check as follows:
(1) Engine oil and engine coolant leakage.
(2) Ignition timing, idle speed. (Refer to page B2-8.)
(3) Operation of emission control system.
4. Recheck the engine coolant levels.
