Locate the serpentine belt routing diagram under the hood near the radiator support or on the engine cover to ensure correct installation. The 2010 Nissan Maxima uses a single serpentine belt to drive the alternator, power steering pump, and air conditioning compressor, making precise alignment critical.
Inspect the belt for cracks and fraying at regular intervals, typically every 15,000 miles. Look for signs of glazing or missing ribs, which indicate immediate replacement. Using the diagram, verify that each component pulley is correctly aligned before tensioning the belt.
Use a proper tensioner tool to relieve tension when removing or installing the belt. The diagram shows the path clearly, allowing you to route the belt accurately and avoid skipping pulleys. Following the diagram reduces wear on the belt and ensures stable operation of all engine accessories.
Keep the belt area clean from oil or coolant leaks, which can accelerate deterioration. Use the diagram to confirm all pulleys are free from debris and rotate smoothly, preventing premature failure and maintaining consistent performance of the 2010 Nissan Maxima’s drive system.
2010 Nissan Maxima Belt Diagram Practical Maintenance and Replacement Guide
Begin by locating the drive belt diagram on the passenger side of the engine compartment or consult the owner’s manual. Identify all belts, including the serpentine belt and accessory belts, and note their routing around pulleys such as the alternator, power steering pump, and AC compressor.
Inspect each belt for visible wear, cracks, fraying, or glazing. Use a flashlight to check the inner ribbing for signs of splitting. Replace any belt that shows damage or has exceeded 60,000 miles of service.
To remove the serpentine belt, locate the tensioner pulley. Use a 14mm or 15mm wrench to rotate the tensioner clockwise, relieving tension. Slide the belt off the pulleys while keeping the diagram for reference.
- Compare the old belt with the replacement to ensure correct length and rib alignment.
- Route the new belt following the diagram precisely, starting with the crankshaft pulley and moving to accessories.
- Rotate the tensioner again and slip the belt over the final pulley.
- Release the tensioner slowly to apply pressure to the belt.
- Manually rotate the engine using a socket on the crankshaft pulley to verify proper tracking and tension.
Check belt alignment with a straightedge or by observing pulley grooves. Misalignment can cause premature wear or belt slippage. Inspect tensioner and idler pulleys for smooth rotation and replace if noisy or seized.
Perform a test run by starting the engine and observing the belt under normal operating conditions. Listen for squeaks and watch for proper movement on all pulleys. Recheck tension after a short drive.
Regular inspection every 12,000 miles or annually helps maintain performance. Keeping a spare belt in the vehicle is recommended for emergency replacements during long trips.
Identifying All Drive and Accessory Belts in the 2010 Maxima
Locate the serpentine belt on the front of the engine, which powers the alternator, power steering pump, water pump, and air conditioning compressor. Confirm the belt routing using the diagram printed on the radiator support or inside the engine compartment cover.
Check the timing belt behind the front engine cover on the passenger side. This belt connects the crankshaft to the camshafts, ensuring precise valve timing. Remove the cover carefully to inspect for cracks, fraying, or oil contamination.
Inspect the accessory belts separately if your Maxima is equipped with a secondary belt for the alternator or air conditioning. These belts run on smaller pulleys and can wear differently from the main serpentine belt.
Follow the belt path from each pulley to verify proper alignment. Look for misalignment, glazing, or missing ribs, which indicate immediate replacement is required. Use a flashlight to examine hidden areas behind tensioners and idler pulleys.
Mark each belt’s orientation before removal to avoid confusion during installation. Note any belt tensioners or adjusters, as some belts require loosening the tensioner to remove or install the belt correctly.
Regularly check all belts for wear signs and maintain proper tension. Replacing belts at manufacturer-recommended intervals prevents engine damage and ensures all accessories operate without interruption.
Step-by-Step Guide for Removing and Installing Belts

Begin by disconnecting the negative battery terminal to prevent accidental electrical contact. Locate the serpentine belt routing diagram, usually on a sticker under the hood or in the owner’s manual, to ensure correct belt placement.
Use a wrench or serpentine belt tool to rotate the tensioner pulley clockwise, releasing tension on the belt. Slide the belt off the alternator, power steering, and air conditioning pulleys carefully, noting the routing path.
Inspect all pulleys for wear, damage, or misalignment before installing the new belt. Replace any worn idler or tensioner pulleys to maintain proper belt tension and prevent premature wear.
Route the new belt according to the diagram, looping it around each pulley correctly. Leave the tensioner pulley for last, then rotate the tensioner to slip the belt into place. Ensure the belt sits fully in the grooves of each pulley.
Double-check the routing to confirm it matches the diagram. Reconnect the negative battery terminal and start the engine. Observe the belt in motion, verifying smooth rotation and proper alignment on all pulleys.
Adjust or reposition the belt if it slips or rubs against pulley edges. Once the belt runs quietly and maintains tension, the installation is complete, ensuring reliable operation of all engine accessories.
Troubleshooting Common Belt Wear and Misalignment Issues
Check your 2010 Nissan Maxima belts for visible cracks, fraying, or glazing on the surface. Any of these signs indicate that the belt needs immediate replacement.
Listen for squealing noises during engine startup or acceleration. High-pitched squeals often signal misalignment or a loose belt tensioner. Inspect the tensioner pulley and adjust or replace it if necessary.
Examine belt tracking across all pulleys. The belt should sit evenly without riding up the pulley edges. Misalignment can cause uneven wear and reduce belt life.
Measure belt tension using a calibrated gauge. For the serpentine belt, deflection should be approximately 0.5 inches (12–13 mm) under moderate thumb pressure at the midpoint. Overly tight belts strain pulleys, while loose belts slip and produce noise.
Inspect pulleys for wobbling, grooves, or debris buildup. Damaged pulleys accelerate belt wear and may require replacement. Ensure pulleys spin freely without resistance or grinding.
Check for oil or coolant contamination on the belt. Fluids soften rubber and lead to slippage. Clean the pulleys and replace any contaminated belts immediately.
Document wear patterns on the belt. Diagonal cracks or feathered edges indicate misalignment between specific pulleys. Correct the alignment and recheck tension before reinstalling a new belt.
