The Genie 52573GT is a genuine OEM Thermostat Housing designed for LRG425 EFI engine-equipped machines, including Genie S and Z series boom lifts and GS large-platform scissor lifts. As a direct OEM replacement sourced through the Genie parts program, this housing is built to the same specifications as the original component it replaces, ensuring a correct, hassle-free installation. Compatible models include the S-40, S-45, S-60, S-65, S-80, S-85, Z-45/22, Z-45/25, Z-45/25J IC Power, Z-60/34, GS-3384, GS-3390, GS-4390, and GS-5390 — cross-reference part number 52573GT against your machine's parts manual to confirm fitment before ordering. When the original housing cracks, warps, or leaks, this part restores proper coolant flow and engine temperature regulation so your equipment stays productive on the job.
Key Features
- Genuine OEM Coolant Integrity — Manufactured to the same material and dimensional standards as the original housing, ensuring a leak-free seal at every coolant port connection.
- LRG425 EFI Engine Specific — Engineered specifically for the LRG425 EFI engine platform, so this housing drops in without rework or adaptation to existing coolant hose routing.
- Broad Fleet Coverage — Fits a wide range of Genie S series telescopic booms, Z series articulating booms, and large-platform GS scissor lifts running the LRG425 EFI engine.
- Restored Engine Temperature Control — A failed or cracked housing disrupts coolant circulation and can cause the engine to overheat; replacing it promptly keeps the engine operating within its designed thermal range.
- Critical System Safety — On aerial lifts, engine overheating can trigger shutdowns at elevation; a properly sealed thermostat housing helps maintain the engine reliability that safe lift operation depends on.
The thermostat housing is the structural enclosure that seats the engine thermostat and connects the cooling system's upper coolant passages to the radiator hose. It directs coolant through or around the radiator depending on engine temperature, allowing the thermostat to regulate heat within the engine's optimal operating range. When the housing cracks or its sealing surfaces deteriorate, coolant loss and overheating follow quickly — making prompt replacement essential to protect the engine and maintain safe machine operation.
