The timing belt is the backbone of your diesel engine's precision. For Land Rover Discovery LR4, Range Rover, Range Rover Sport, and Range Rover Velar owners running the venerable 3.0L TDV6 diesel powerplant, a properly maintained timing belt assembly ensures reliable synchronization between crankshaft and camshaft. When your original unit shows wear or shows signs of age, replacement is not optional—it's critical to engine longevity.
This OEM-specification timing belt suit from Partsmost delivers exactly what your engine demands: a full assembly including the timing belt, timing pulley, and dual idler pulleys (including the 1311306 variant). Engineered to the exact standards of the original equipment, this kit restores factory performance and reliability across the entire timing drive system.
Whether your Discovery LR4 is now 10+ years old, your Range Rover Vogue entered the 2013+ generation, or your Jaguar XJ / XF / F-PACE relies on the same proven TDV6 architecture, this timing belt suit is the solution trusted by engine professionals. It's a preventative replacement that pays for itself in avoided downtime and catastrophic engine damage.

Installation Notes
Difficulty Level: Intermediate to Advanced
Timing belt replacement requires mechanical expertise and specialized tools. If you lack experience, professional installation is strongly recommended.
Estimated Time: 4–6 hours
What You'll Need
- Timing belt tensioning tool (or equivalent gauge)
- Socket set (metric, comprehensive range)
- Torque wrench (critical for crankshaft pulley)
- Engine lifting equipment or support system
- Gasket scraper and cleaning supplies
- Alignment marks or timing reference tool
Installation Steps
- Disconnect battery negative terminal and discharge any residual electrical charge
- Remove engine undertray, radiator support, and serpentine belt(s) to access timing cover
- Locate and mark cylinder head timing marks (ensure engine is at TDC on cylinder 1)
- Remove timing cover bolts carefully and set cover aside with gasket
- Release idler pulley tension via adjustment bolt to slacken old belt
- Remove old timing belt, timing pulley, and worn idler pulleys
- Install new idler pulleys (both 1311306 units) with torque specification per service manual
- Fit new timing pulley to crankshaft, torqued to specification (typically 110–140 N⋅m)
- Install new timing belt, hand-routing around crankshaft, idler, and camshaft pulleys
- Apply tension using timing tool; verify belt slack is within specification (typically 10 mm deflection at midspan)
- Rotate engine by hand 2 full revolutions; recheck timing mark alignment at TDC
- Reinstall timing cover with new gasket, torque bolts evenly
- Reattach serpentine belt, radiator support, and undertray
- Reconnect battery and start engine; listen for abnormal noise; verify no warning lights
⚠ Critical Warning: Incorrect belt tension or timing misalignment will cause engine damage, loss of power, or catastrophic valve-to-piston interference. If you are not confident in your mechanical ability, have a qualified technician perform this work. Do not skip the post-installation verification steps.
