FAQs
What does the 0.9 bar pressure rating mean?
The 0.9 bar rating indicates the pressure at which the cap is designed to open, allowing excess pressure to be released from the cooling system. This prevents the system from exceeding safe operating pressure limits.
How often should I replace my radiator cap?
It is recommended to inspect your radiator cap during regular maintenance intervals (e.g., oil changes) and replace it if it shows signs of wear, damage, or if you suspect it is not holding pressure correctly. Many mechanics suggest replacement every 2-3 years or as per vehicle manufacturer recommendations.
Can I use this cap on a different car model?
This Quinton Hazell FC59 cap is specifically designed for certain Citroen BX and Peugeot 309 models. Using it on a vehicle it wasn't designed for may result in improper pressure regulation and potential engine damage. Always confirm compatibility.
What are the dimensions of this radiator cap?
The cap has a height of 25 mm and a diameter of 57 mm.
Is this an OEM part?
This is a genuine Quinton Hazell part, designed to meet or exceed OEM specifications for quality and performance for the compatible vehicle models.
What does the MPN 'FC59' signify?
MPN stands for Manufacturer Part Number. FC59 is the unique identifier for this specific radiator cap manufactured by Quinton Hazell.
Troubleshooting
Engine overheating despite new cap
Ensure the cap is correctly fitted and sealed. Check for other cooling system issues such as low coolant levels, thermostat failure, or radiator blockages.
Coolant leaking from around the cap
Verify the cap is the correct part number for your vehicle and that the radiator neck is clean and undamaged. The seal on the cap might be faulty, or the neck may be warped.
Cap difficult to remove or install
Ensure the engine is cool. Check for debris or damage on the radiator neck and the cap threads. Never force the cap.
