Changing Oil And Oil Filter; Torque Exhaust Manifold Nuts; Valves; Air Cleaner - Volvo 760 Owner's Manual

1987 Volvo 760

Changing oil and oil filter

Oil and oil filter are first changed at the 600-1,200 mile (1,000-2,000 km) service. Thereafter, changes should be made as specified by this
table:
SAE 15W/40 is recommended for use in driving conditions that raise oil temperature and increase oil consumption (i.e., mountain driving;
trailer towing).
Note: SAE 15W/40 must not be used at low ambient temperatures; see viscosity chart.
Volvo recommends the use of oils with the American Petroleum Institute (API) label. This label certifies that the oil conforms to the
applicable standards and specifications of the API.
If driving conditions include:
Extended periods of idling and/ or low-speed operation
Frequent short trips (less than 7 miles = 11 km)
Extended periods of driving in dusty and/or sandy
areas
Trailer towing
Driving mountainous areas
Primarily highway driving
Frequent trips of longer than 7 miles = 11 km
pg. 106 Servicing

Torque exhaust manifold nuts

The manifold nuts should be torqued at the 600-1,200 mile (1,000-2,000 km) inspection. A loose manifold could alter air/fuel ratio and
cause an increase in emissions and/or poor driveability.

Valves

The valve clearance should be checked and, if necessary, adjusted every 30,000 miles (50,000 km).

Air cleaner

Replace the air cleaner cartridge with a new one every 30,000 miles (50,000 km). The cartridge should be replaced more often when driving
under dirty and dusty conditions. The filter cannot be cleaned and, therefore, should always be replaced with a new one.
Vacuum fittings, hoses and connections
Unstable idle, misfiring, or poor emission control is often caused by leaking vacuum hoses or connections. Check hoses and connections on
distributor vacuum unit, connections on heater control servo systems and hydraulic brake servo.
Checking and adjusting idle speed
Your Volvo is equipped with an electronically controlled idle speed system that requires no checking or adjustment.
Fuel system cap, tank and lines, and connections
The effectiveness of the fuel system to contain hydrocarbons is dependent largely on a leak free system. Check for proper sealing of
gasoline filler cap which contains "0" ring-type seals. Check all evaporative hoses in vehicle for tightness. Check fuel lines under vehicle
and repair if necessary.
Fuel (line) filter
The fuel filter is located on the left suspension tower brace. This filter is to be changed every 60,000 miles (100,000 km). The filter is
replaced as one complete unit.
Replace more frequently if contaminated fuel is introduced into the tank (or if there is reason to suspect that this has occurred).

Then the correct oil/oil filter change interval
is:
EVERY 5,000 miles = 8,000 km
or EVERY 3 MONTHS
WHICHEVER COMES FIRST
EVERY 5,000 miles = 8,000 km
or EVERY 6 MONTHS
