After Repairs Leak Check

AFTER REPAIRS LEAK CHECK

PURPOSE
Initially fill the cooling system and check for leaks prior to starting the engine. Any leaks which are detected may be repaired before the engine and cooling system become hot.

NOTE: It is much easier to repair a leak on a cold engine than on a hot engine.

HOW
- Fill the cooling system, with the bleeder screw open, until the radiator is full.

Bleed Bolt:

- Tighten the bleed bolt as soon as coolant starts to run out in a steady stream without bubbles.

Pressuring Testing Cooling System:

- Apply pressure to the system with a pressure tester.
- Carefully check for leaks around:
- All hoses and clamps.
- Water pump sealing surfaces.
- Any cooling system component which was removed or replaced.
- If no leaks are detected continue with the fill and bleed procedure.
