Fuel (line) filter
The fuel filter is located on the firewall. This filter is to be changed every 30,000 miles. The filter is
replaced as one complete unit.
Fuel (tank) filter
A filter is installed in the suction line in the fuel tank. Its function is to prevent any dirt in the tank from
being sucked up to the fuel pump. The filter should be cleaned every 15,000 miles.
Air cleaner
Replace the air cleaner cartridge with a new one every 30,000 miles. The cartridge should be replaced
more often when driving under dirty and dusty conditions. No cleaning of any kind is to be made
between the above mentioned intervals.
pg. 52 Emission control systems
Checking and adjusting idle speed and mixture ratio and manifold balance
This check should be made every 15,000 miles.
The idling speed should also be adjusted and the mixture ratio and manifold balance checked at the 600
miles 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 (Champion BN 9 Y or corresponding). Use molybdenum
disulphide ("Molykote") to lubricate the threads and torque to 13-14.5 ft. lbs. (18-20 Nm).
When changing the 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.
