Multiquip 45628 Coolant Fill Bottle 4QT

The Multiquip 45628 Coolant Fill Bottle 4QT is a genuine OEM component designed for PRX series hybrid ride-on power floats. As a direct OEM replacement, part 45628 is produced to the same specifications as the original unit, ensuring a correct, hassle-free installation. If your PRX machine's coolant reservoir is cracked, leaking, or missing, this is the exact bottle your machine was built with.

Key Features

• OEM-Matched Capacity: — 4-quart volume matches the original coolant system design of PRX series hybrid power floats, maintaining the correct fluid reserve level.
• Exact-Fit Replacement: — Engineered to mount directly in the original position on PRX series machines, with matching port sizing and bracket attachment points.
• PRX Series Compatibility: — Verified fitment for PRX hybrid ride-on power float equipment, eliminating guesswork when sourcing a replacement coolant reservoir.
• Coolant System Integrity: — A damaged or deteriorated coolant bottle can lead to fluid loss, air ingestion into the cooling circuit, and overheating of the hybrid drive system — this OEM bottle restores the closed-loop cooling system to full function.
• Genuine Multiquip OEM Part: — Sourced directly from Multiquip, part number 45628 carries the same material and dimensional standards as the original factory-installed component.

The coolant fill bottle serves as the expansion reservoir for the machine's liquid cooling system, holding the overflow coolant that expands as the engine or hybrid drive system heats up during operation. It allows the cooling circuit to breathe and maintain consistent fluid levels without introducing air into the system. When the bottle cracks, leaks, or loses its seal, coolant levels drop unpredictably, which can cause the engine or drive components to run hot and sustain damage over time.
