The Multiquip 145016474 Water Pump is a genuine OEM Water Pump designed for LT12, LT12P, LT12D, and SLT12D series light towers. As a direct OEM replacement sourced through Multiquip's authorized parts network, this pump is built to the exact specifications of the original component. It is confirmed compatible with the MQ Towable Light Tower LT12 as well as LT12P, LT12D, and SLT12D models, making it the correct choice when servicing these units. When it's time to restore your cooling system to full working order, the part is the part to reach for.
Key Features
- Genuine OEM Cooling System Integrity — Manufactured to the original flow rate and pressure specifications, ensuring the cooling circuit performs exactly as the engine demands.
- Drop-In Installation — Matches the original mounting flange, port sizing, and drive interface, so the pump installs directly onto the engine without modification.
- Confirmed Fitment — Verified for LT12, LT12P, LT12D, and SLT12D Multiquip light towers, covering both towable and standard light tower configurations.
- Sustained Engine Temperature Control — A properly functioning water pump keeps coolant circulating at the correct rate; a worn or seized pump leads to overheating and unplanned shutdowns during extended lighting operations.
- Long-Term Durability — Built with OEM-grade materials rated for continuous-duty engine environments, including the heat cycling typical of generator-driven light tower applications.
The water pump circulates coolant between the engine block and the radiator, drawing heat away from critical engine components and maintaining a safe operating temperature. On a light tower like the LT12 series, where the engine may run for extended overnight shifts, consistent coolant flow is essential to preventing heat-related engine stress. When the water pump wears out — through bearing failure, seal leaks, or impeller erosion — coolant circulation drops, engine temperature climbs, and the machine will shut down to protect itself, leaving your worksite without light.
