Product Description:

 
Heater water hose
OE NO.:  31338301 31338302

Applicable vehicle type: For Volvo

 
The heater pipe connects the engine cooling system to the heater core, primarily serving to convey heat-laden coolant from the engine cooling system to the heater core. Through heat exchange, the heater core's fan then directs warm air into the passenger compartment, providing a warm and comfortable driving environment for the driver and passengers. It also facilitates windscreen defrosting.
 
 
Core Fault Types:
1. Pipe Ageing and Cracking
Reduced or absent cabin heating
2. Joint Leakage
Intermittent heating with minor leaks; rapid coolant depletion and engine warning with severe leaks
3. Pipe Clogging/Blockage
Low heating output temperature (barely warm), with inconsistent temperatures from left and right vents
4. Pipe Detachment
Sudden loss of heating accompanied by audible fluid leakage sounds from engine bay
5. Wear caused by vibration
No issues when cold; after engine warms, pipe expansion causes tighter contact with metal components, accelerating wear.
6. Material Corrosion Resistance Failure
Rust spots or bulges appear on the inner walls of water pipes, or green/white corrosion products form at joints.
