Product Description:

Auto radiator water hose
OE NO.:  31319215 31338598

Applicable vehicle type: For Vol vo

The radiator water pipe of a car is a key component of the cooling system. The core objective of daily maintenance is to prevent aging, leakage, cracking, and bulging of the water pipe, thereby avoiding engine overheating faults caused by coolant loss.

Inspection Timing and Frequency

• Routine Inspection: It is recommended to inspect the radiator hoses and connections every 20,000 kilometers or during each vehicle maintenance service.
• Special Scenario Inspection: An additional inspection is required before long-distance highway driving and after exposure to extreme temperature differentials (e.g., transitioning from severe cold to intense heat) to prevent hidden damage to hoses caused by abrupt temperature changes.
• Inspection Precondition: Operations must be performed only after the engine has completely cooled down to avoid scalding from hot coolant spray.

Key inspection items include

• Tube condition: Inspect the surface of the water pipe for cracks, hardening, stickiness, bulges, or damage. If rubber water pipes lose elasticity and do not rebound when pressed, they are aged and need replacement. If silicone water pipes exhibit delamination or debonding, they should also be replaced promptly.
• Fittings and clamps: Check the connection points between both ends of the water pipe and the radiator, engine block for coolant leakage traces (typically white crystalline deposits or residual green/pink liquid). Inspect whether the clamps are loose or rusted; if the clamps have insufficient elasticity, replace them with stainless steel clamps to prevent water pipe detachment due to clamp failure.
• Ancillary components: Some lower radiator water pipes are equipped with internal spiral springs. Ensure that the springs are not fallen off or deformed to prevent the water pipe from being sucked flat by the water pump suction. Check the branch fittings of bypass water pipes and heater water pipes to avoid missed faults caused by fitting cracks.
