The Multiquip 42745 Lower Radiator Hose Tier 4 is a genuine OEM replacement designed for HTX6H and STX6H ride-on power trowels. Sourced directly from Multiquip, this hose meets the original equipment specifications for Tier 4 engine configurations, ensuring a correct, trouble-free installation. Confirmed fitment for the HTX6H and STX6H models makes 42745 the dependable choice when servicing your machine's cooling system.
Key Features
- Genuine OEM Construction — Manufactured to the exact hose diameter, length, and material spec required by Tier 4 engine cooling systems, with no guesswork on fitment.
- Direct-Fit Replacement — Connects to the factory lower radiator port on HTX6H and STX6H trowels exactly as the original, allowing straightforward installation without modification to clamps or routing.
- Tier 4 Engine Compatibility — Specifically engineered for the Tier 4 engine variant found in HTX6H and STX6H models; not interchangeable with non-Tier 4 cooling hose configurations.
- Sustained Coolant Flow — A structurally sound lower radiator hose maintains consistent coolant circulation between the engine block and radiator, preventing overheating during continuous troweling operations.
- Cooling System Integrity — A cracked or collapsed lower radiator hose is a leading cause of unexpected engine temperature spikes; replacing it at first sign of wear protects the engine from heat-related damage.
The lower radiator hose carries coolant from the bottom of the radiator back to the engine water pump, completing the cooling circuit that keeps engine temperatures within safe operating range. On ride-on trowels running Tier 4 engines, maintaining this flow is critical — if the hose collapses, cracks, or softens, coolant volume drops and the engine can overheat rapidly under load. Replacing a worn lower radiator hose promptly is one of the most straightforward ways to protect the engine from costly heat-related damage.
