That being said, here's a general outline. This is not a substitute for a proper repair manual specific to your vehicle's year and engine code. The details can vary slightly depending on the exact engine code. You should obtain a factory service manual for precise instructions and diagrams.
What you'll need:
* Factory service manual: This is crucial. It will have the precise timing mark locations and torque specifications.
* Timing belt tools: These may include a crankshaft pulley holder, a camshaft alignment tool, and possibly a special tool to keep the tensioner from springing back.
* Socket set and wrenches: Various sizes will be needed.
* Jack and jack stands: To safely support the vehicle.
* New timing belt kit: This typically includes the belt, tensioner, and idler pulleys (replace these when doing a timing belt job).
General Steps (Consult your manual for precise details):
1. Safety First: Disconnect the negative battery cable. Support the vehicle securely on jack stands.
2. Access the Timing Belt: Remove any components necessary to access the timing belt cover. This often involves removing various accessories and possibly the front engine cover.
3. Locate Timing Marks: Your service manual will show you the exact locations of the marks. These are typically:
* Crankshaft: A mark on the crankshaft pulley or a notch on the crankshaft itself.
* Camshaft(s): Marks on the camshaft sprockets (there may be two camshafts).
4. Align the Marks: Rotate the crankshaft (using a socket on the crankshaft bolt) until all the marks are perfectly aligned. This is critical. Turning the engine by hand while ensuring the marks are aligned is crucial.
5. Install the New Timing Belt:
* Install the new timing belt, ensuring it sits correctly in the sprockets and guides.
* Use the proper tensioning tool to tension the belt according to the manufacturer's specifications in your service manual.
* Check the alignment of the marks one last time after tensioning.
6. Reassemble: Put everything back together, ensuring all bolts are tightened to the correct torque specifications (found in your service manual).
7. Reconnect the Battery: Reconnect the negative battery cable.
8. Start the Engine: Carefully start the engine and listen for any unusual noises.
Extremely Important Considerations:
* Engine Rotation: Be very careful of the direction you rotate the engine. Rotating it in the wrong direction can cause damage.
* Tension: The timing belt needs to be properly tensioned. Too loose, and it will skip teeth; too tight, and it can cause premature wear and damage to components.
* Mark Alignment: Precise alignment of the marks is paramount. Even a slight misalignment can result in poor engine performance or catastrophic engine failure.
Again, this is a simplified overview. Without the specific details from your vehicle's repair manual, attempting this could seriously damage your engine. Consult a reputable mechanic if you're unsure about any aspect of this process. The cost of a professional job is far less than the cost of repairing a damaged engine.
