FAQ

Frequently Asked Questions

What does a radiator cap do and why is pressure important?
A pressure-relief radiator cap seals the cooling system and maintains a specified pressure (typically 0.5–1.1 bar above atmospheric). This elevated pressure raises the boiling point of the coolant by approximately 10–20°C above its normal boiling point, preventing boil-over in high-temperature operations. In Saudi Arabia's extreme heat, a properly functioning radiator cap is critical to prevent engine overheating.
Do you supply radiator caps for commercial vehicles in Saudi Arabia?

How do I test if a radiator cap is working correctly?
Test a radiator cap with a radiator cap pressure tester: (1) Attach the cap to the tester adapter; (2) Pump to the cap's rated pressure; (3) A good cap will hold pressure for at least 10 seconds; (4) A bad cap will not hold pressure or opens at a lower pressure than rated. Visual inspection: check rubber seals for cracking or deterioration. Replace a cap that fails the pressure test or shows seal degradation.
