Symptoms & Testing

Common failure symptoms
  • Overheating
  • Coolant on the ground at the front
  • Bent or clogged fins
  • Steam from the front of the truck
How to test it
  1. 1. Pressure test the cooling system cold.
  2. 2. Look for stains and crust at seams and tanks.
  3. 3. Check for airflow blockage between the condenser and radiator.

Symptoms narrow the list of possibilities. They never confirm a diagnosis on their own — test before replacing anything.
