ENGINE MAINTENANCE Before Engine Starts (Cont'd) Spark plug: Canada Standard type BPRSES Hot type BF R4 ES Cold type BPRSES 5. Install new spark plugs. Reconnect high tension ables according to Nos. indicated on them. M : Spark plug 20 - 29 N-m (2.0 - 3.0 kg-m, 14 - 22 ft-Ib) CHECKING IGNITION WIRES (HIGH- -TENSION CABLES) 1. Check the high-tension cables for cracks, dam- age, burned terminals and proper fit. LII than 30 kn SMAOISA 2. Shake the high- tension cable while measuring resistance to check for intermittent breakes. CHECKING AUTOMATIC TEMPERATURE CONTROL (A.T.C.I AIR CLEANER 1.ka that vacuum hoses (Intake manifold to temperature sensor, idle compensator and vacuum motor) are securely connected in cor- rect position. 2. Check each hose for cracks or distortion. 3. Check A.T.C. system for function by proceed- ing as follows: Confirm that engine is cold before starting test. With engine turned off, check position of air control valve by hand or mirror. ll _ll Hot an inlet Cold air Inlet SEFJzea Air control valve is in correct position if its cold air inlet is open and hot air inlet is closed. 4. Start engine and keep idling. Immediately after starting engine, air control valve is in correct position if its cold air inlet is closed and hot air inlet is open. 5. Check that air control valve gradually opens to cold air inlet side as engine warms up. When environmental temperature around tempera- ture sensor is low, allow more time for engine warming up to facilitate smooth operation of air control valve If the above test reveals any problem in the operation of air control valve, carry out the further Inspection described In Section EF.
