Signs it is Time to Replace Your Radiator Hose(s)

Prevent system contamination and coolant leaks that could cause your engine to overheat by checking for these common signs of Radiator Hose damage / failure:

INTERNAL DAMAGE
Soft / mushy hose ends, usually about 2 inches from the clamp. Internally Damaged Hose

LEAKAGE
Moisture, drips or coolant bleed marks on or around the hose clamps, connectors or hose. Leaking Hose

HEAT DAMAGE
Slight swelling, or a hardened, glossy cover that is covered with cracks. Heat Damaged Hose

OZONE DAMAGE
Tiny, parallel cracks in the cover, usually at hose bends. Ozone Damaged Hose

ABRASION DAMAGE
Rubbing marks on, or damage to the hose cover. Abrasion Damaged Hose

OIL CONTAMINATION
Soft or spongy to the touch - bulges and swelling are readily apparent. Oil Contaminated Hose

Cooling System Maintenance | Tips & Tools

Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:

• Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
• Consider replacing the Thermostat and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
• Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
