Cooling Hose Kit — Upper 1.50 in ID, Lower 1.73 in ID SKU: QT4338

This cooling hose kit restores steady coolant flow between the engine and radiator, helping the tractor stay at the right temperature during mowing, loader work, and field chores. Replacing both molded hoses together is a practical way to prevent leaks and heat-related downtime.

The molded bends follow the factory routing for a clean fit and dependable sealing at the necks and housings. Fresh hoses grip clamps better, resist softening, and stand up to daily use in dusty, vibrating conditions.

• Upper hose inside diameter: 1.50 in (38.1 mm) for a snug fit at the upper neck.
• Lower hose inside diameter: 1.73 in (43.9 mm) to match the lower neck/water pump connection.
• Molded curves for proper routing and clamp alignment
• Durable construction for reliable service in everyday farm conditions

Installation Tip: Drain coolant below hose level, clean both necks until smooth, and use new clamps. Fit and tighten the lower hose first, then the upper; refill with the correct coolant mix and bleed air after warm-up.

Count on this kit to deliver a tight seal and consistent cooling performance for routine farm work.
