Checking Radiator Hoses
When
Check the condition of the radiator hoses every 250 hours.
Overview
Dry, cracked radiator hoses or loose clamps can cause a coolant leak. A coolant
leak will cause the engine to overheat, possibly leading to permanent damage.
Regular inspection of the radiator hoses will help to identify coolant leaks.
There are two radiator hoses on the LTN. The upper hose
(a)
supplies coolant to
the engine. The lower hose
(b)
returns coolant to the radiator.
Procedure
Perform the procedure below to check the radiator hoses.
1. Inspect each hose for cuts, cracks, abrasions, or bulges. Replace the hose if
any of these conditions exist.
2. Squeeze each hose to check the elasticity. A hose in serviceable condition will
yield to slight pressure. Replace the hose if it appears to be stiff or brittle.
3. Check the hose clamps
(c)
to make sure that they are tight. Check for coolant
leaks at the hose connections. Tighten loose clamps as needed.
Result
The radiator hoses have now been checked.
