Renault Laguna Phase 2 Petrol 1.8 and 2.0 16V — Technical Data Sheet 2000

Technical data sheet AUTO-VOLT N°773 (December 2000) for the Renault Laguna Phase 2 (from April 1998) — a comprehensive service reference covering all petrol engine variants. The 1.8-litre F4P 760 delivers 120 hp (88 kW) at 5,750 rpm with 16.5 daN.m torque at 3,500 rpm, paired with a JC5 gearbox. The higher-output 2.0-litre F4R 780 produces 140 hp (102 kW) at 5,500 rpm and 18.8 daN.m at 3,750 rpm, featuring variable inlet camshaft timing for improved efficiency, also with JC5 transmission. A 1.6 16-valve K4M option (110 hp, JB3 gearbox) is also documented. Engine management relies on Siemens Sirius 32 control with sequential multipoint injection and integrated ignition mapping; four independent ignition coils are controlled directly by the 90-terminal ECU. Cooling system uses a centrifugal pump driven by the accessory belt, aluminium radiator, and an 89°C/101°C thermostat (7.5 mm stroke) with dual-speed fan motor responding at 99°C low/102°C high activation. Coolant capacity is 7 litres (Glacéol RX specification), requiring renewal every 120,000 km or 4 years; air intake filter replacement interval is 40,000 km or 4 years. Sensor data provided includes air pressure transducer (4,000 Ω), throttle position sensor (1,212 Ω across terminals 75–74), crankshaft position sensor (200–270 Ω with 58-tooth trigger wheel), and Lambda oxygen sensor (0–0.8 V output, dual probes on F4P 760). The document includes a complete 90-terminal ECU pinout assignment table, component location schematics for all major systems, and a commercial variant identification chart for accurate model matching during diagnosis and repair work.
