Scan for Cooling System Leaks After Radiator Install

Cost Savings

Checklist Tasks

• Fill system with correct coolant mix and fully bleed trapped air.
• Install pressure tester on radiator or reservoir to monitor for leaks.
• Pump to specified PSI and watch for pressure drop over 15–20 minutes.
• Inspect all new hose connections closely for any coolant beads or seepage.
• Check radiator end tanks and seams for leaks under pressure.
• Examine thermostat housing and gasket for coolant seepage.
• Scan heater core pipes for leaks if hoses were disturbed during install.
• Inspect drain plug and petcock for drips from unseated new seals.
• Check bleed screw and overflow tube for bubbles from trapped air.
• Monitor water pump weep hole for drops when system is pressurized.
• Verify radiator cap holds specified pressure without releasing coolant.
• After testing, check under vehicle for drips or puddles.
