THE COOLING SYSTEM HOSES DETERIORATE AND FAIL BECAUSE OF INADEQUATE HEAT RESISTANCE. FAILURE FIRST OCCURS AT THE CLAMP CONNECTIONS, CAUSING COOLANT FLUID TO BE LEAKED OR SPRAYED ONTO THE ENGINE COMPARTMENT COMPONENTS.

IF THE VEHICLE IS OPERATED WITH A LOW COOLANT LEVEL, THECOOLING SYSTEM TEMPERATURE AND PRESSURE WOULD RISE VERY QUICKLY. COOLANTREACHING THE HOT EXHAUST MANIFOLD CAN IGNITE AND CAUSE AN ENGINE COMPARTMENTFIRE.

REPLACE THE DEFECTIVE COOLING SYSTEM HOSES WITH IMPROVED HEAT RESISTANT HOSES, MODIFY THE COOLANT RECOVERY SYSTEM TO PREVENT SUDDEN INCREASES IN COOLING SYSTEM TEMPERATURE AND PRESSURE, AND REPLACE ENGINE COMPARTMENT COMPONENTS WHICH MAY HAVE BEEN DAMAGED OR WOULD DETERIORATE WITH TIME.
