UPPER RADIATOR HOSE FOR DAVID BROWN K946849

This K946849 upper radiator hose is designed for the cooling system of David Brown tractors. Installed on the upper part of the radiator according to the intended application, it is suitable for models 1410 and 1412. The 37 mm inner diameter is the first thing to check to correctly identify this part number and ensure a proper fit on your machine.

A connecting hose for the cooling system

The upper hose connects the upper components of the cooling system and ensures the flow of coolant between the engine and the radiator, depending on the tractor’s configuration. With this type of part, the condition of the rubber and the correct fit are just as important as the part number, since an improperly fitted hose can complicate installation or cause a leak.

This part number is designed for use on a radiator. It is located in an area exposed to heat and pressure fluctuations within the system, which explains why an old hose may harden, crack, or show signs of leakage around the clamps.

Identification Marks for Part Number K946849

To select this part, the key dimensional reference is the 37 mm inner diameter. This measurement should be compared to the diameter of the relevant fittings and to the old hose that was removed. Part number K946849 serves as a second practical identifier when searching for a specific replacement.

For a radiator hose, the overall shape, the orientation of the ends, and the position within the engine compartment must also match the existing installation. If your tractor has already undergone a circuit modification, a visual inspection before ordering is recommended.

Known applications on David Brown tractors

This upper hose is suitable for the following tractors:

• David Brown 1410
• David Brown 1412

These two models are the applications explicitly associated with this part number. If you are working on a tractor similar to this series, it is best not to assume compatibility without verifying the part number of the existing part and the required inner diameter.

When to Replace This Upper Hose

Replacing an upper radiator hose is generally recommended when the part shows visible signs of wear or when maintenance of the cooling system requires its removal. Common signs to watch for include: surface cracks, a hose that has become too hard or too soft, localized swelling, traces of coolant near the fittings, or insufficient adhesion at the ends.

Before finalizing your selection, verify part number K946849, the location on the radiator, and the 37 mm inner diameter. These identifiers will help you more reliably identify the correct hose for your David Brown 1410 or 1412.

FAQ — Frequently Asked Questions

What is the purpose of an upper radiator hose on a tractor?

An upper radiator hose circulates coolant between the upper part of the engine cooling system and the radiator, depending on the tractor’s configuration. This part operates at high temperatures and must remain in good condition to ensure a clean, leak-free connection.

Is this K946849 hose compatible with the David Brown 1410 and 1412 models?

Yes, this part number is suitable for David Brown 1410 and 1412 tractors. To ensure you’ve chosen the correct part, also verify the specified inner diameter of 37 mm and compare the overall layout of your old hose with that of the replacement hose on your machine.

What measurement should you check first before ordering this hose?

The key measurement to check is the 37 mm inner diameter. This measurement helps ensure a proper fit on the cooling system fittings. It’s also helpful to compare the position of the upper hose and the appearance of the old hose you removed.

When should an upper radiator hose be replaced?

Replacement is necessary as soon as cracks, significant hardening, swelling, or seepage at the fittings appear. On a radiator hose, these signs of wear indicate that the part should be inspected immediately to prevent a coolant leak.
