- If low, refill with a 50/50 mixture of Toyota-approved coolant.
Inspect Transmission Fluid
- Check the transmission dipstick for level and condition.
- If low or burnt smelling, replace the fluid and filter.

3. Inspect and Replace Worn Components

Inspect Belts and Hoses
- Visually inspect for cracks, fraying, or signs of wear.
- Replace any damaged belts or hoses with OEM parts.
Brake Inspection
- Remove the wheels to inspect brake pads and rotors.
- Replace any worn brake components, ensuring proper installation.

4. Clean and Tighten

Clean Up Any Spills
- Use degreaser to clean any oil or fluid spills in the engine bay.
Tighten Loose Components
- Ensure that all bolts and connections in the engine compartment are tight.
