Here's a general outline. Specifics may vary slightly depending on your engine (2.4L or 3.5L). Consult your owner's manual for diagrams and specific instructions for your Altima. This is a general guide only and does not replace a proper workshop manual.
Tools You'll Need:
* New drive belt: Get the correct belt size. Your owner's manual or a parts store can help you identify this.
* Socket wrench set: Various sizes, likely including metric sizes.
* Wrench set: Again, likely metric.
* Ratchet: To use with your sockets.
* Jack and jack stands: Crucially important for safety. Never work under a car supported only by a jack.
* Wheel chocks: For added safety.
* Gloves: To protect your hands.
* Shop rags: To clean up any spilled fluids.
* Possibly a belt tensioner wrench: Some tensioners require a specialized tool. Check your owner's manual. You *might* be able to use a long breaker bar or similar to apply enough leverage to some, but use caution.
* Pry bar (carefully): Sometimes used to help with belt routing, but use very carefully to avoid damaging anything.
Procedure (General Steps):
1. Safety First: Engage the parking brake firmly, chock the wheels, and jack up the front of the car. Securely support the car on jack stands. Never work under a car supported only by a jack.
2. Locate the Belt: Identify the drive belt. It runs across various pulleys (alternator, power steering pump, A/C compressor, etc.).
3. Identify Tensioner(s): Locate the belt tensioner(s). There's usually a way to release tension on the belt to allow for removal and installation. This is often done by turning a bolt or using a specialized tool on the tensioner pulley.
4. Release Tension: Carefully release tension on the belt. This is the trickiest part. Consult your repair manual for specifics on how your tensioner operates.
5. Remove the Old Belt: Once tension is released, carefully remove the old belt from the pulleys.
6. Install the New Belt: Carefully route the new belt around the pulleys in the same path as the old belt. Make sure it sits correctly in all the grooves.
7. Release Tensioner: After the belt is routed, let go of the tensioner to make the belt snug and tight.
8. Check Belt Tension: Make sure the belt is properly tensioned. It should not be too loose or too tight. Your owner's manual might give you a specific guideline on how much deflection the belt should have when pressed.
9. Lower the Car: Carefully lower the car back to the ground.
10. Test: Start the engine and check for any squealing or other unusual noises. Inspect the belt to make sure it's still properly seated.
Important Considerations:
* Consult your owner's manual: This is absolutely crucial. The specifics of your 2000 Nissan Altima's drive belt replacement will vary slightly.
* Repair Manual: A repair manual specific to your vehicle's year and engine will provide detailed instructions and diagrams. This is highly recommended.
* Professional Help: If you're unsure about any step, or if you're uncomfortable working on your car, take it to a qualified mechanic. Improperly installed belts can cause significant damage.
