- Remove Front Passenger Wheel: This provides better access to the engine bay.
- Remove Splash Shield: Locate and remove the plastic splash shield in the passenger side wheel well. This usually involves a few plastic clips and screws.
Relieving Belt Tension and Removing the Old Belt
This is where the serpentine belt tool or a long ratchet comes in handy.
- Locate the Tensioner: The belt tensioner is typically located on the passenger side of the engine, often near the crankshaft pulley. It has a pulley wheel and a spring-loaded arm.
- Identify Tensioner Bolt: Find the large bolt head on the tensioner arm (usually 14mm or 19mm, check your manual or the new part).
- Relieve Tension: Attach your serpentine belt tool or a long ratchet with the correct socket to this bolt head. Apply steady, counter-clockwise (or clockwise, depending on your specific model – observe the tensioner’s movement) pressure to rotate the tensioner arm, releasing tension on the belt.
- Remove Belt: While holding the tensioner arm open, carefully slip the serpentine belt off one of the pulleys (e.g., the power steering pump or alternator pulley).
- Slowly Release Tensioner: Once the belt is off, slowly release the pressure on the tensioner arm.
- Remove Belt Completely: Route the old serpentine belt out of the engine bay. Now is a good time to inspect it for cracks or wear.
Removing the Old Tensioner
The tensioner itself is usually held by 2-3 bolts.
- Locate Mounting Bolts: Identify the bolts securing the tensioner assembly to the engine block. These are typically smaller than the tensioner relief bolt.
- Remove Mounting Bolts: Use your ratchet and appropriate socket to carefully remove these bolts. Keep track of them; they might be different lengths.
- Extract Old Tensioner: Once the bolts are out, the old tensioner assembly should slide out of its mounting position. It might require a little wiggle.
- Inspect Mounting Area: Check the mounting surface for any debris or corrosion. Clean it if necessary.
Installing the New Tensioner
This is essentially the reverse of removal.
- Position New Tensioner: Carefully align the new tensioner assembly with its mounting holes on the engine block.
- Insert Mounting Bolts: Start threading the mounting bolts by hand to prevent cross-threading. If using anti-seize, apply a thin layer to the bolt threads.
- Tighten Bolts: Snug the bolts down initially, then use your torque wrench to tighten them to the manufacturer’s specified torque. Over-tightening can strip threads, while under-tightening can lead to a loose tensioner. Consult your Odyssey’s service manual for exact torque specs.
Reinstalling the Serpentine Belt
This can be the trickiest part for some.
- Consult Belt Diagram: Refer to the belt routing diagram, usually found under the hood on a sticker or in your owner’s manual. It’s crucial to route the new belt correctly.
- Route the Belt: Carefully snake the new serpentine belt around all the pulleys, leaving one pulley (often the tensioner pulley itself or an easily accessible one like the alternator) for last.
- Relieve Tension Again: Attach your serpentine belt tool or ratchet to the tensioner bolt and apply pressure to open the tensioner arm, just as you did when removing the old belt.
- Slip Belt into Place: While holding the tensioner open, slip the belt over the final pulley. Double-check that the belt is seated correctly in all the grooves of all the pulleys.
- Slowly Release Tension: Gently release the tensioner arm, allowing it to apply pressure to the new belt.
Final Checks and Test Drive
Don’t skip these critical steps.
- Inspect Belt Routing: Visually inspect the entire serpentine belt to ensure it’s properly seated on all pulleys and routed according to the diagram.
- Check for Tools: Make sure no tools are left in the engine bay.
- Reconnect Battery: Reconnect the negative battery terminal.
- Start Engine: Start the engine and listen carefully. There should be no squealing or chirping. Observe the belt for any wobble or abnormal movement. Let it run for a few minutes.
- Turn Off Engine: Once satisfied, turn off the engine.
- Reinstall Components: Reinstall the splash shield and the front passenger wheel.
- Lower Vehicle: Carefully lower your Odyssey off the jack stands.
- Test Drive: Take a short test drive, listening for any unusual noises and checking for proper power steering and A/C operation.
