The Bomag 05903237 Cooler Hose is a genuine OEM component designed for BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, and BW 125 AC-4 tandem rollers. Sourced directly from Bomag, this cooler hose matches the original in material, dimensions, and connection routing — so it drops in without guesswork. Whether you're servicing a BW 100-series or a BW 125-series tandem roller, part number 05903237 is the correct replacement to restore proper cooling system flow.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and pressure specifications, ensuring the hose handles the thermal and hydraulic demands of tandem roller cooling circuits
- Direct Replacement Fit — matches the original routing, end fittings, and hose length so installation is straightforward with no cutting or adapting
- Broad Tandem Roller Coverage — fits BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, and BW 125 AC-4 tandem rollers, covering multiple drive and drum variants across the series
- Sustained Cooling Performance — a sound cooler hose maintains consistent coolant flow to the heat exchanger; a cracked or collapsed hose leads to overheating, unplanned stops, and potential engine damage
- Verified Part Number — ordering by part number 05903237 confirms you're getting the correct hose for your machine, not a close substitute that may not seal or route correctly
The cooler hose carries coolant between the engine and the cooling system's heat exchanger, maintaining the operating temperature needed to keep a tandem roller running efficiently during long compaction passes. If the hose degrades — through cracking, swelling, or a failed connection — coolant flow is restricted or lost entirely, causing the engine to run hot and risking thermal shutdown or internal damage. Replacing a worn cooler hose promptly with the correct OEM part keeps the cooling circuit sealed and the machine operating at the right temperature.
