how to fix Honda CR-V CVT overheating issues

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.
• Disconnect the battery to prevent electrical shorts.

2. Check and Replace CVT Fluid

• Sub-steps:
  1. Raise the vehicle using a jack and secure it on jack stands.
  2. Locate the CVT drain plug and place a drain pan underneath.
  3. Remove the drain plug and allow the old fluid to completely drain.
  4. Replace the drain plug and torque it to the manufacturer’s specifications (typically around 30 lb-ft).
  5. Refill the CVT using the recommended fluid type (Honda HCF-2 or equivalent) through the fill port.
  6. Start the vehicle and allow it to warm up, then check the fluid level again and top off if necessary.

3. Inspect Cooling System

• Sub-steps:
  1. Check the coolant level in the reservoir and radiator; refill with the correct coolant type if low.
  2. Inspect the radiator for any obstructions or damages.
  3. Test the operation of the radiator fan; replace if faulty.
  4. Ensure that there are no blockages in the CVT cooler lines.

4. Replace Transmission Temperature Sensor (if faulty)

• Sub-steps:
  1. Locate the transmission temperature sensor on the CVT unit.
  2. Disconnect the electrical connector and remove the mounting fasteners.
  3. Replace the sensor with a new one and torque to the manufacturer's specifications.
  4. Reconnect the electrical connector.
