Checking and adjusting idling speed and mixture ratio
These checks should be made every 15,000 miles.
The idling speed should be adjusted and the mixture ratio check at the 600-1,200 mile inspection.
Fuel system cap, tank and lines and connections
The effectiveness of the fuel system to contain hydrocarbons is largely dependent on a leak-free system.
Check for proper sealing of gasoline filler cap which contains "O" ring type seals. Check all evaporative
hoses in vehicle for tightness. Check fuel lines under vehicle and repair if necessary.
Inspection of fuel injection electrical connections
The electrical connections and fuel lines in the injection system should be checked for chafing and
corrosion every 15,000 miles.
III Engine Ignition Components
Change spark plugs
The spark plugs should be changed every 15,000 miles.
However, city driving or fast highway driving may require changing after 7,500 miles of driving. When
fitting new plugs, be sure to fit the right type:
Volvo Part No. 273545-4 or equivalent. Torque to 14.5-21.7 ft. lbs. (20-30 Nm).
When changing the spark plugs, check that the suppressor connectors are in good condition. Cracked or
damaged connectors should be replaced.
When changing spark plugs, clean the cables and cable terminals, also the rubber seals. If the car is
driven on roads where salt is used during the winter, coat the cables with silicone.
Ignition timing
Distributor advance mechanism
The ignition timing should be inspected at the 600-1,200 miles inspection and after that every 15,000
miles.
All adjusting work should be done with the proper equipment. The distributor is one of the most
sensitive engine units. Careless handling can lead to decreased engine output and high fuel consumption
or even serious damage to the engine.
The distributor advance mechanism should be checked every 30,000 miles.
Ignition wiring
The ignition system consists of a primary and secondary system. The secondary systems are the high
tension leads connecting the distributor cap with the spark plugs and the coil.
These wires should be inspected at each engine tune-up, and should be replaced if cracked, frayed or
