Appearance: Moisture, drips or coolant bleed marks on or around the hose clamps, connectors or on the hose itself.
Cause: Insufficient clamp torque, deterioration of the hose or connector.
Solution: Retighten adjustable tension clamps after a brief run-in period. Alternatively, use constant-tension clamps, which automatically adjust with the heating and cooling of the system. A beaded connector offers better sealing and retention characteristics. Brass and cast iron fittings adhere to common rubber compounds after time, which reduces possibility of leaks, as does the use of sealants and viscous gels. Replace with the recommended Gates hose. Gates uses compounds that offer better resistance to the negative effects of compression set.
