1986 Volvo 740 GL, GLE, Turbo ● Extended periods of idling and/or low-speed operation ● Frequent short trips (less than 7 miles = 11 km) EVERY 5,000 miles = 8,000 km ● Extended periods of driving in dusty and/or sandy or EVERY 3 MONTHS areas WHICHEVER COMES FIRST ● Trailer towing ● Driving mountainous areas ● Primarily highway driving EVERY 5,000 miles = 8,000 km ● Frequent trips of longer than 7 miles = 11 km or EVERY 6 MONTHS WHICHEVER COMES FIRST 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. pg. 99 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 (48,000 km). Air cleaner Replace the air cleaner cartridge with a new one every 30,000 miles (48,000 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 next to the fuel pump. This filter is to be changed every 60,000 miles (96,000 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). Timing Gear Belt The timing gear belt should be adjusted at the 600-1200 mile (1000-2000 km) inspection. We recommend the belt be replaced every 50,000 miles (80,000 km). pg. 100 Servicing file:///K|/ownersdocs/1986/1986_740/86740_07.htm (7 of 15)12/30/2006 7:51:36 AM
