Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, inspection light, brake fluid tester.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fluids

Engine Oil:
1. Remove the oil dipstick and check the oil level.
2. If low or burnt, drain the old oil using an oil pan.
3. Replace with the manufacturer-recommended oil type (e.g., 0W-20 for most Honda CR-V models).
4. Replace the oil filter using an oil filter wrench; ensure the rubber O-ring is seated properly on the new filter.
5. Refill the engine with the correct amount of new oil and check for leaks.
Transmission Fluid:
1. Locate the transmission dipstick and check the fluid level and color.
2. If the fluid is burnt or low, drain the old fluid from the transmission pan.
3. Replace with manufacturer-specified transmission fluid.
4. Recheck the level after running the engine for a short period.

3. Inspect and Replace Brake Components

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect brake pads for excessive wear; if worn below the minimum thickness, replace them.
Check the rotors for heat spots or warping; resurface or replace as necessary.
Reassemble the brake components and ensure they are tightened to the manufacturer’s specifications.

4. Inspect Belts and Hoses

Visually inspect all belts for cracks, fraying, or glazing.
Check hoses for leaks, bulges, or soft spots; replace any damaged components.
Adjust or replace belts as necessary according to manufacturer specifications.
