Bomag Coolant Pump | Part 05718463

The Bomag 05718463 Coolant Pump is a genuine OEM Coolant Pump designed for Bomag tandem rollers across the BW 161, BW 190, BW 202, BW 203, BW 205, and BW 206 series. Sourced directly from Bomag, this coolant pump meets the original engineering specifications for the machines it serves, delivering the exact fit and flow characteristics required for proper engine cooling. Compatible fitment spans models including the BW 161 AD-4, BW 161 AC-4, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, BW 205 AD 4, BW 206 AD-50, and additional variants listed below, giving fleet operators a single, trusted part across a wide range of tandem roller configurations.

Key Features

• OEM Coolant Flow Specification — manufactured to Bomag's original flow-rate and pressure tolerances, ensuring the engine cooling circuit performs exactly as engineered for tandem roller operation
• Direct Drop-In Replacement — matches the original mounting flange, port sizing, and drive interface for a straightforward swap on BW 161, BW 190, BW 202, BW 203, BW 205, and BW 206 tandem rollers
• Broad Tandem Roller Coverage — confirmed fitment across more than 20 model variants, including the BW 161 AC-50, BW 202 AD-4 EU-Flex, BW 203 ADO-4, BW 206 ADO-50, and BW 203 AD-4 AM, among others
• Engine Protection You Can Count On — a correctly functioning coolant pump keeps operating temperatures in range during sustained compaction work; a worn or failing pump risks overheating and engine damage in demanding paving and compaction conditions
• Genuine Bomag Part — part number 05718463 is an authentic Bomag component, backed by Bomag's OEM quality assurance for the tandem roller lines it supports

The coolant pump is responsible for circulating engine coolant through the engine block, cylinder head, and radiator, maintaining the operating temperature within the range the engine needs to run efficiently and safely. On ride-on tandem rollers like the BW 161 and BW 202 series, the engine works continuously under load, making consistent coolant circulation critical to long-term engine health. When the coolant pump wears out — through seal failure, impeller erosion, or bearing degradation — coolant flow drops, temperatures rise, and the engine becomes vulnerable to overheating, which can cause costly internal damage if not addressed promptly.
