Coolant Pump / BS4
The Coolant Pump / BS4 circulates coolant throughout the engine to maintain optimal operating temperature.
Designed for BS4-compliant diesel engines, this pump ensures consistent coolant flow through the engine block, cylinder head, and radiator. Its high-strength impeller and precision bearings provide smooth operation, minimal friction, and long service life. Built to withstand continuous heat cycles and heavy-duty usage, the pump prevents overheating and supports efficient thermal management in commercial vehicles.
By delivering stable coolant circulation, the pump enhances engine performance, protects sensitive components, and helps maintain fuel efficiency. It also reduces thermal stress, prevents coolant boiling, and improves overall reliability during prolonged operation under demanding load conditions.
Key Features
- High-performance coolant pump for BS4 engines
- Ensures efficient coolant circulation and temperature control
- Durable impeller and bearings for long life
- Reduces risk of overheating and thermal damage
- Suitable for heavy-duty commercial applications
