  • Locate the Leak: Clean the engine with degreaser and run the engine. Identify the source of the oil leak.
  • Replace Gaskets or Seals: If the leak is from a gasket or seal, replace it with a new one. Ensure to clean the mating surfaces before installation.

2. Fixing Coolant Leaks

  • Identify the Source: Inspect hoses, the radiator, and the water pump for leaks.
  • Repair or Replace: Replace damaged hoses or components as necessary. For small leaks, coolant sealant may be effective.

3. Cooling System Inspection

  • Flush the Cooling System: If the coolant is contaminated, consider flushing the cooling system and replacing the fluid.
  • Replace Thermostat: If the thermostat is faulty, replace it to ensure proper coolant flow.

4. Electrical Repairs
