Why Is the Correct Radiator Cap Important?
The radiator cap plays an important role in maintaining the correct pressure within the cooling system.
A properly functioning pressure cap helps:
- Maintain the specified cooling system pressure
- Increase the coolant's boiling point
- Reduce unnecessary coolant loss
- Prevent pressure loss caused by deteriorated seals
- Support consistent engine operating temperatures
- Maintain reliable cooling system operation
A worn or faulty radiator cap can contribute to coolant leakage, pressure loss and overheating problems.
Suitable For
- Classic Morris Mini – applicable models
- Classic Leyland Mini
- Classic Rover Mini
- Mini Moke – applicable models
- Classic Mini cooling systems requiring a 15 PSI radiator cap
Important Fitment Information
Classic Mini and Moke cooling systems have used different radiator caps and pressure ratings over the years.
Always confirm that your radiator requires a 15 PSI pressure cap before ordering.
Check the following:
- Original radiator cap pressure rating
- Radiator filler neck depth
- Cap sealing arrangement
- Vehicle model and cooling system configuration
Important: Installing a higher-pressure radiator cap than specified for your cooling system may place unnecessary stress on the radiator, hoses and other cooling components.
Installation Recommendations
When replacing your radiator cap:
- Allow the engine to cool completely before removing the existing cap.
- Inspect the radiator filler neck for corrosion or damage.
- Check that the new cap seals correctly.
- Inspect the cooling system for signs of coolant leakage.
- Confirm the correct coolant level after installation.
Never remove a radiator cap while the engine is hot or the cooling system is pressurised.
