Radiator Hose: Service and Repair

Lower Radiator Hose Removal and Installation 
Removal 

1. Drain the engine coolant.

2. Clean any dirt off the quick connector (A), radiator, and lower radiator hose.
3. Pull out the lock (B) by hand, then wiggle the quick connector, and remove it from the radiator. Do not use any tools to remove the quick

connector.

4. Remove the clamp (C) from both ends of the lower radiator hose, and remove them from the thermostat and quick connector.

Installation 

1. Check the quick connector (A) and set ring (B) for cracks or damage. If the connector and/or set ring are cracked or damaged, replace the

connector.

2. Make sure the set ring is in place inside the quick connector. If the set ring is off the connector, replace the quick connector.
3. Replace the O-ring (C) in the quick connector.
4. Check the lock (D). If the lock is damaged or deformed, replace it. When installing the new lock to the connector, slide it straight down along the

groove.

5. Install a new lower radiator hose on the quick connector, and install the clamp.
6. Clean the connecting surface of the radiator (E), then apply clean engine coolant around the connecting surface.
