1987 Volvo 760
Timing Gear Belt (Turbo Models only)
The timing gear belt should be adjusted at the 600-1200 mile (1000-2000 km) inspection. We recommend that the belt be replaced every
50,000 miles (80,000 km).

LH Jetronic 2.2 fuel system (760 GLE)
The LH-Jetronic 2.2 fuel injection system is all-electronic and is microprocessor-controlled. It can continually compensate for variations in
engine load, speed and temperature to give the best economy and power. The most unique feature of the system is an air mass meter that
measures the mass of the inducted air instead of the volume. In this way the system can make instantaneous adjustments for changes in air
temperature or density, thus always assuring the best economy with the lowest-possible exhaust emissions.
Lambda-sond
TM
(oxygen sensor) System
This is an emission control system designed to reduce emissions and improve fuel economy. An oxygen sensor monitors the composition of
the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic unit. This adjusts the air-fuel ratio to provide
optimum conditions for combustion and efficient reduction of the three major pollutants (hydrocarbons, carbon monoxide and nitrous gases)
by a 3-way catalytic converter.
