Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repair.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, 10mm socket, fluid catch pan.
Remove the transmission fluid dipstick and check the fluid level.
If low, add the recommended type of CVT fluid (check owner’s manual for specifications).
If fluid is burnt or contaminated, drain the old fluid:
- Place a fluid catch pan under the transmission pan.
- Remove the transmission pan bolts using a 10mm socket.
- Carefully lower the pan and drain the old fluid.
Clean the transmission pan and replace the filter if equipped.
Reinstall the pan and refill with new CVT fluid.

3. Inspect and Repair CVT Cooler

Tools Required: Hose clamps, screwdriver, wrench set.
Visually inspect the CVT cooler and hoses for leaks or damage.
If damaged, replace the cooler:
- Disconnect the inlet and outlet hoses from the cooler.
- Remove the mounting bolts and carefully detach the cooler.
- Install the new cooler and reconnect hoses securely, ensuring no leaks.

4. Check Radiator Functionality

Tools Required: Radiator pressure tester, coolant.
Inspect the radiator for any blockages or leaks.
Use a radiator pressure tester to check for leaks.
If the radiator is malfunctioning, replace it:
- Drain the coolant and detach the hoses.
- Remove mounting bolts and carefully lift out the radiator.
- Install the new radiator and reconnect hoses.
