The Multiquip 79000511 Radiator is a genuine OEM component designed for HTX44Y4 and HTX44Y5 hydrostatic ride-on power trowels. As a direct OEM replacement, this radiator is built to the exact specifications of the original part, ensuring proper fitment and full cooling capacity for the engine. Sourced directly through authorized Multiquip supply channels, the 79000511 is the correct-spec radiator for these HTX series machines. DHS Equipment stocks this part to keep your trowel running at the right operating temperature and back in service fast.
Key Features
- Genuine OEM Cooling Capacity — Manufactured to the exact core size, inlet/outlet configuration, and flow rate of the original radiator, so the engine maintains its correct operating temperature range.
- Direct-Fit Replacement — Mounts to the existing radiator brackets and hose connections on HTX44Y4 and HTX44Y5 trowels with no modification to the cooling system or frame.
- HTX Series Compatibility — Confirmed fitment for HTX44Y4 and HTX44Y5 Whiteman hydrostatic ride-on power trowels.
- Engine Protection Under Load — A properly functioning radiator prevents heat buildup during extended finishing passes, protecting the engine from thermal overload and premature wear.
- Overheating Risk Eliminated — A cracked, leaking, or clogged radiator can cause the engine to overheat and shut down mid-pour. Replacing with the correct OEM unit restores full thermal management.
The radiator is the core of the engine's liquid cooling system. It dissipates heat by circulating coolant through a series of tubes and fins, transferring thermal energy away from the engine block and into the surrounding air. On a ride-on power trowel like the HTX44Y4 and HTX44Y5, the engine works continuously under load during concrete finishing operations — making reliable cooling essential. When a radiator develops a leak, becomes blocked, or suffers physical damage, coolant loss and rising engine temperatures follow quickly, risking engine damage or unplanned shutdown on the slab.
