Coolant Pump Hose (Pipe) To Thermostat For 1.8 16V And 2.0 16V Engines
This replacement hose connects the coolant pump to the thermostat housing on 1.8 16V and 2.0 16V petrol engines used in various Citroën and Peugeot models. Designed as a direct-fit service part, it restores reliable coolant circulation and helps maintain correct engine operating temperature. Ideal for professional workshops and experienced DIY mechanics searching by part number 1341F9.
Function
The hose (pipe) channels coolant from the water pump to the thermostat housing, enabling the thermostat to regulate coolant flow to the radiator. A leak or blockage on this line can cause overheating, poor heater performance, or coolant loss. The component must retain pressure resistance, heat tolerance and secure sealing at both ends.
Compatibility
- Citroën C4 (with 1.8 16V and 2.0 16V engines)
- Citroën C4 Picasso (with 1.8 16V and 2.0 16V engines)
- Peugeot 307 (with 1.8 16V and 2.0 16V engines)
- Peugeot 407 (with 1.8 16V and 2.0 16V engines)
- Engine Types: 1.8 16V, 2.0 16V

Installation Recommendations
- Work On A Cold Engine: Allow The Engine To Cool Completely Before Starting To Avoid Burn Injuries From Hot Coolant.
- Drain Or Lower Coolant Level To Prevent Spillage And Make Access Easier; Capture And Dispose Of Old Coolant According To Regulations.
- Loosen And Remove Hose Clamps, Then Detach The Hose From The Pump And Thermostat Housing. Inspect Mating Surfaces, Hoses, Seals And O-Rings; Replace Seals If Damaged.
- Fit New Hose Ensuring Correct Orientation And Full Engagement Over Spigots; Use New Quality Clamps Or Reuse OEM Clamps Only If In Good Condition.
- Refill With Manufacturer-Specified Coolant And Bleed The Cooling System To Remove Air Pockets. Run Engine To Operating Temperature And Recheck For Leaks.
- Recommended For Professional Fitment: Use Appropriate Tools, Protect Adjacent Components From Spills, And Test System Pressure After Installation.
Why This Part Commonly Fails
- Age And Heat Exposure: Repeated Thermal Cycling Causes Rubber And Plastic To Harden, Crack Or Split Over Time.
- Chemical Degradation: Incorrect Coolant Mixtures Or Contaminants Can Accelerate Deterioration.
- Mechanical Stress And Vibration: Movement At Hose Connections Or Poorly Secured Clamps Lead To Leaks.
- Corrosion Or Damage At Fittings: Metal Spigots And Clamps Can Corrode, Creating Sealing Problems.
- Related Component Failure: Faulty Thermostat Or Overheating Incidents Increase Pressure And Stress On The Hose.
Maintenance And Replacement Advice
Inspect This Hose During Routine Cooling System Service Or When Servicing The Thermostat/Water Pump. Replace If Any Cracks, Soft Spots, Swelling, Oil Contamination Or Coolant Leaks Are Present. Many hoses Are Replaced As Part Of Water Pump Or Thermostat Service To Avoid Repeat Labour.
