1985 Volvo DL, GL and Turbo Torque 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 emission and/or poor driveability. Valves The valve clearance should be checked every 30,000 miles (50,000 km). 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, EGR valve (where applicable) and connections on heater control servo systems and hydraulic brake servo. Camshaft drive belt The timing belt tensioner should be adjusted at the 600-1,200 mile (1,000-2,000 km) inspection. pg. 55 Servicing Engine Fuel System CI system (Continuous Injection) B21F-Turbo engine (Turbo models) Fuel injectors are open and inject fuel as long as the engine is operating. This system has few moving parts, is reliable and meets the exhaust emission standards at maximum efficiency. Air supplied to the engine is continuously measured and determines the amount of fuel injected. The air flow is regulated by the throttle valve. The air flow sensor and the fuel distributor are built as a single unit. A lever is actuated by the air flow to produce continuous fuel distribution. file:///K|/ownersdocs/1985/1985_DL_GL_and_Turbo/85240_03a.htm (12 of 18)12/30/2006 7:49:16 AM
