Komatsu Radiator Caps

The numbers refer to the pressure rating in bar (approximately 13 psi vs. 16 psi). A 1.1 bar cap maintains higher system pressure, which raises the coolant boiling point slightly and improves cooling efficiency. Using the wrong pressure rating can cause coolant loss, overheating, or radiator damage. Always match the cap rating to your Komatsu equipment's specification.
