Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the engine is cool to avoid burns.
  • Disconnect the battery to prevent electrical issues.
2. Locate the Leak
  • Pressure Testing: Attach the pressure tester to the coolant reservoir and pump it to the specified pressure (usually 15-20 psi). Observe for any leaking areas.
  • Visual Inspection: Check all components inspected during the diagnostic steps for visible coolant.
3. Replace Affected Components
  • Coolant Reservoir: If cracked, remove the reservoir by disconnecting the hoses and bolts securing it. Replace with a new reservoir.
  • Hoses: Cut away damaged hoses and replace with OEM hoses. Use hose clamps to secure them.
  • Water Pump: If leaking, drain coolant, remove the water pump by disconnecting the inlet and outlet hoses, and unbolting it from the engine. Install a new water pump and gasket.
  • Radiator: If leaking, drain the coolant, and remove the radiator by disconnecting the fan and hoses. Replace with a new radiator.
4. Refill and Bleed the Cooling System
  • Refill the cooling system with the appropriate coolant mixture (usually a 50/50 mix of antifreeze and distilled water).
  • Bleed the system by running the engine with the radiator cap off until the thermostat opens and air bubbles escape.
