Function
The Upper Timing Cover protects the timing belt and associated components (tensioner, idler pulleys, camshaft and crankshaft seals) from external contamination and helps retain lubricant in the correct areas. It also provides mounting points and alignment for the front timing assembly and contributes to noise dampening.
Common Failure Modes
Typical reasons for replacement include plastic cracking or warping due to heat aging, impact damage on removal or installation, broken mounting tabs, and oil leaks from degraded seals or gaskets that allow contamination of the belt area. Damage is often noticed as oil stains at the front of the engine, unusual timing belt wear, or rattles from the timing cover area.
Replacement Procedure (Overview)
- Prepare workspace and secure vehicle on level ground. For safety, follow standard workshop safety procedures.
- Remove engine cosmetic covers and relieve accessory drive belts as required to access the timing cover.
- Loosen and remove crankshaft pulley/harmonic balancer if required for lower access.
- Remove fasteners holding the upper timing cover. Carefully detach the cover to avoid damaging tabs and surrounding components.
- Inspect timing belt, tensioner, idlers and seals while cover is off. Replace the timing belt and tensioner if wear or age-related deterioration is present (recommended when performing extensive front-end work).
- Clean mating surfaces thoroughly. Fit new gasket or apply correct sealant where specified. Install new cover, torque bolts to manufacturer specifications, and reassemble in reverse order.
- Start engine and check for leaks and proper operation. Verify timing belt tension and alignment after reassembly.
Installation Recommendations
- Use the OEM part numbers (9684193080 / 9686975480 / 0320AJ) to ensure correct fitment.
- Always replace the timing belt, tensioner and idler pulleys if they show signs of wear or if recommended by the service schedule—access is easiest with the cover removed.
- Replace the gasket/sealing material and any fasteners that are damaged or corroded. Use manufacturer-specified torque settings to avoid cracking the cover or stripping threads.
- Inspect adjacent seals (crankshaft and camshaft) and replace if oil leakage is present to prevent premature belt contamination.
- Perform final checks for oil leaks and correct belt tension before putting the vehicle back into service.
Why This Part Fails Most Often
Plastic timing covers age under high underhood temperatures and exposure to oil, which can make them brittle and prone to cracking. Improper removal or overtightening during previous services often damages mounting tabs. Oil leaks from worn seals accelerate deterioration and contaminate the timing belt, increasing the risk of belt failure.
When searching or ordering, include the OEM numbers 9684193080, 9686975480, or 0320AJ to improve accuracy and speed up parts identification.
