  6. Rubber Components Burning
1. Overheated Engine
Tools Required:
  • Coolant tester
  • Torque wrench
  • Pliers
  • Screwdrivers

Repair Instructions:

  1. Inspect Coolant Levels: Ensure the coolant is at the proper level. If low, top it up with the appropriate coolant mixture.
  2. Check for Leaks: Inspect hoses, radiator, and water pump for leaks. Replace any damaged components.
  3. Thermostat Check: If the thermostat is stuck, replace it. This requires draining the coolant and removing the thermostat housing.
  4. Coolant Flush: If the coolant is dirty, perform a coolant flush.
2. Burning Oil
Tools Required:
  • Oil dipstick
  • Shop towels

  3. Replace Oil Filter: If oil contamination is present, consider replacing the oil filter along with an oil change.
  4. Engine Repair: If the oil burning is due to internal engine problems (like worn piston rings), further disassembly may be required.
3. Burning Brake Components
Tools Required:
  • Jack and jack stands
  • Lug wrench
  • Torque wrench
  • Brake cleaner
  • New brake pads and/or rotors

Repair Instructions:

  1. Lift Vehicle: Use a jack to elevate the car and remove the wheels.
  2. Inspect Brakes: Check the thickness of the brake pads; if below the manufacturer’s specification, replace them.
  3. Replace Components: If the rotors are damaged, machine or replace them as necessary.
  4. Reassemble: Reinstall wheels and lower the vehicle. Torque lug nuts to manufacturer specification.

Tools Required:
  • Multimeter
  • Wire strippers/crimpers
  • Electrical tape

Repair Instructions:

  1. Identify Faulty Wiring: Replace any damaged or frayed wiring.
