Rubber coolant hoses harden, crack, swell, or seep with age and heat cycling. Signs this hose may need replacing include visible cracking or bulging, coolant weeping at the hose, a low-coolant condition, or a sweet coolant smell. If a failed heater/bypass hose is the cause, this Dayco 80319 replaces it. Coolant hoses are best inspected and replaced during routine cooling-system service.
