Installation Guide
Difficulty Level: Intermediate | Time: 1–2 hours
-
Disconnect the negative battery terminal. Safety first—disable any automatic shutdown systems.
-
Remove the plastic engine cover. Most Discovery 4 and Range Rover models use clips and two bolts.
-
Locate the tensioner pulley. It sits on the driver's side of the engine bay, spring-mounted to the block.
-
Release belt tension. Rotate the tensioner counterclockwise using a breaker bar—most use a 15mm socket.
-
Remove the old belt, idlers, and tensioner. Mark routing on the engine cover before disconnecting.
-
Install new idler pulleys. Torque bolts to 18–22 Nm (13–16 ft-lbs). Confirm bearings spin freely with no grinding.
-
Fit the new tensioner assembly. Align the spring slot and torque the main bolt to 25–30 Nm.
-
Route the new serpentine belt. Follow the routing diagram printed on the engine cover or timing cover. Do not force—the belt should slip smoothly onto each pulley.
-
Check belt tension. Spin the belt by hand. It should require moderate pressure to rotate and show no slack on the longest unsupported span.
-
Run the engine at idle for 60 seconds. Listen for squealing. If present, stop and re-check routing and tensioner spring alignment.
-
Reconnect battery, clear any warning codes, and test drive. Belt should run silent under full load.
⚠️ Important: Never operate the engine with a loose or misaligned belt. Failure to route correctly may result in alternator/water pump failure or complete serpentine system shutdown. If unsure, consult a certified Land Rover technician. Improper installation voids the manufacturer warranty.
Complete Your Engine Service
A properly functioning serpentine belt system is non-negotiable for engine longevity. Keep your Land Rover, Range Rover, or Discovery running at peak efficiency with OE-specification components and a 12-month warranty.
