why does my Toyota RAV4 XA40 (2013-2018) make a loud noise when I accelerate

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine turned off and cooled down.

2. Inspect and Repair Exhaust System

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Visually inspect the entire exhaust system from the engine to the tailpipe for signs of rust, holes, or loose connections.
  3. Tighten any loose clamps or hangers found during inspection.
  4. If a leak is found, replace the damaged section of the exhaust pipe or muffler.
  5. Reinstall any removed components and lower the vehicle.

3. Check Engine Mounts

• Sub-steps:
  1. Inspect the engine mounts for cracks or separation.
  2. If damaged, use a socket set to remove the bolts securing the engine mount to the chassis.
  3. Replace with new engine mounts, ensuring proper alignment.
  4. Torque bolts to the manufacturer’s specifications (generally around 40-50 ft-lbs but check specific values for the RAV4).

4. Inspect Drive Belts

• Sub-steps:
  1. Open the hood and visually inspect the drive belts for cracks, fraying, or signs of wear.
  2. If the belt is damaged, use a wrench to loosen the tensioner and remove the old belt.
  3. Install the new belt, following the routing diagram typically found on a sticker under the hood.
  4. Re-tension the belt and ensure it is properly aligned on all pulleys.
