Coolant Storage Tank Pressure Test Guidelines
Maintaining proper pressure in coolant storage tanks is essential for system integrity and preventing costly breakdowns. Below are recommended pressure test frequencies based on usage context and condition:
Regular Vehicle Coolant Tanks
- Recommended interval: every 12 to 18 months
- Align with routine coolant replacement schedules
- Tests should check for leaks, weakened seals, or plastic degradation
Industrial/Heavy-Duty Equipment
- Recommended interval: every 6 to 12 months
- Includes construction machinery, generators, etc.
- More frequent testing due to harsher operating conditions
Tanks with Damage History or Repairs
- Recommended interval: every 3 to 6 months
- Applies to tanks with prior cracks, impacts, or leaks
- Immediate pressure test required after any repairs or part replacements
Testing Procedure
A standard pressure test involves using a hand pump to simulate the system's operating pressure (typically 10-15 psi for vehicles) and checking for pressure drops over 5-10 minutes. Any pressure drop indicates a potential leak.
Important: Always consult manufacturer guidelines for your specific tank model, as some high-performance or specialized tanks may require unique testing schedules.
