The 1992 Volvo 940 features a 2.3L engine, which is a freewheeling engine. This means that if the timing belt stretches past its useful life, the valves will most likely not hit the pistons and will not cause extensive engine damage. Volvo has not recommended a specific interval to change the timing belt, but previous service use and history indicates that the timing belt should be changed every 60,000 miles to prevent over-stretching. A special damper locking wrench is required for this job, which is available at any Volvo dealership.
Tools Used: Tools, Set of wrenches, Set of sockets, Damper locking wrench No. 5284, 3 mm drill bit, Torque wrench

Remove the upper cooling fan cover and the cooling fan using the appropriate wrenches and sockets. Loosen the accessory drive belt tensioners, then lift the belts off the pulleys. Remove the upper timing belt cover using the appropriate socket.
Turn the crankshaft clockwise until the timing mark on the crankshaft is lined up. The marks line up at the 11 o’clock position. Check the timing marks on the camshaft and the intermittent sprocket. The camshaft timing mark lines up at the 11 o’clock position and the timing mark on the intermittent sprocket lines up at the 3 o’clock position.
