  Tune-Up - Checklist
  • Flush dirt, bugs and leaves from front of radiator with a brush and garden hose.
  • Inspect the radiator cap. Replace it if the rubber gasket is broken, dried out or missing.
  • Check the condition and level of coolant.
  • Clean the system and replace anti-freeze.
  • Inspect radiator and radiator hoses for leaks, cracks or soft, mushy condition.
  • Tighten all clamps. Replace hoses as needed.
  • Look for the heater hose running from the engine to the heater core under the dash.
  • Replace swollen or cracked hoses.
  • If after ten minutes the hoses are cool, they could be clogged.
  • Inspect all engine belts for wear and cracks. Replace if worn, cracked or glazed.
  • Adjust loose belts.
  • Check the thermostat operation by running the engine for 10-15 minutes.
  • Beware of an engine that runs too hot or too cool.
  • Tighten loose bolts on the thermostat housing at the engine.
  • Clean the engine exterior.
  • Excessive oil and dirt will hide leaks, or insulate the engine, causing it to run hot.
