- Lower radiator hose: routes coolant from the engine to the radiator on the return path.
- Coolant duty: handles the heat and pressure of the engine cooling system.
- Direct fit: replaces the lower radiator hose on the listed GM trucks and SUVs.
A radiator hose can crack, swell, harden, or leak with age and heat cycling. Signs it may need replacing include visible coolant seepage at the ends, a soft or bulging hose, or a low-coolant condition. If a failed lower hose is the cause, this replaces it.
