COOLANT CAP 10LB

This is a 10 psi (10LB) coolant reservoir cap for heavy-duty Mack and Volvo trucks. It seals the expansion tank to maintain system pressure and prevent coolant loss. The cap is commonly replaced when the old one fails to hold pressure, which can lead to overheating or visible coolant leaks.
