Coolant Line/Hose
Inspect the hoses at regular intervals. Replace hoses that are cracked, feel brittle when squeezed, or swell excessively when the system is pressurized.
For all vehicles: In areas where specific routing clamps are not provided, be sure that hoses are positioned with sufficient clearance. Check clearance from exhaust manifolds and pipe, fan blades, drive belts and sway bars. Improperly positioned hoses can be damaged, resulting in coolant loss and engine overheating.
Ordinary worm gear type hose clamps (when equipped) can be removed with a straight screwdriver or a hex socket. To prevent damage to hoses or clamps, the hose clamps should be tightened to 4 Nm (34 inch lbs.) torque. Do not over tighten hose clamps.
When performing a hose inspection, inspect the radiator lower hose for proper position and condition of the internal spring.
