Replacing the timing belt on your Mitsubishi Endeavor is a critical task that requires mechanical knowledge and precision. It's always best to entrust this job to a qualified mechanic. However, if you're determined to do it yourself, here's a general overview of the process:
1. Preparation:
- Gather all the necessary tools, including a timing belt kit (containing a new belt, tensioner, and idler pulleys), a crank pulley holder, a camshaft locking tool, and a torque wrench.
- Follow safety precautions by disconnecting the negative battery terminal to avoid accidental starting.
2. Removal:
- Remove the front crankshaft pulley by first removing the serpentine belt. Use a crank pulley holder to keep the crankshaft from turning.
- Remove the timing belt cover and inspect the belt for signs of wear or damage.
- Use the camshaft locking tool to lock the camshafts in place, ensuring they don't move during belt replacement.
- Loosen the tensioner pulley bolt and remove the old timing belt.
3. Installation:
- Before installing the new timing belt, inspect the pulleys and replace any that appear worn or damaged.
- Align the marks on the timing belt with those on the camshaft and crankshaft gears.
- Install the new timing belt and apply light tension.
- Reinstall the tensioner pulley and tighten the bolt to the specified torque.
- Remove the camshaft locking tool and ensure the timing marks still align correctly.
4. Reassembly:
- Reinstall the timing belt cover and the front crankshaft pulley.
- Install the serpentine belt and make sure all other components are reinstalled securely.
5. Adjustment:
- Once everything is reassembled, use a timing light or diagnostic tool to verify the timing is set correctly.
- If necessary, make slight adjustments to the tensioner pulley to obtain the correct timing.
6. Testing:
- Start the engine and let it run for a few minutes. Listen for any unusual noises or signs of incorrect timing.
- If everything seems normal, take the Endeavor for a test drive to ensure it performs smoothly.
Remember, the timing belt replacement process is complex and requires precise alignment of components. If you're not confident in your abilities, it's safer to seek professional assistance from a qualified mechanic to ensure your vehicle's timing is set accurately.
