- Authorized Parts Source — Sold by DHS Equipment as an authorized Multiquip parts distributor, so you receive the correct part with full confidence in its origin.
The radiator overflow mount is a structural bracket that holds the coolant overflow reservoir in a fixed position on the machine frame. When the engine reaches operating temperature, coolant expands and is directed into the overflow reservoir; as the engine cools, that coolant is drawn back into the radiator. If the mount becomes cracked, corroded, or missing entirely, the reservoir can shift or detach, interrupting this cycle and leading to coolant loss, overheating, or damage to surrounding components. Replacing a failed mount promptly with the correct OEM part restores proper reservoir positioning and protects the engine's cooling circuit.
