Key Features

• Robust Construction: Crafted from durable materials that resist corrosion and high temperatures, the pump delivers long‑term reliability even under demanding driving conditions.
• Efficient Flow Rate: Engineered to provide consistent coolant flow, it helps prevent overheating and protects critical engine components such as pistons, valves, and cylinder heads.
• Compact Design: Its streamlined shape allows for easy installation in tight engine bay spaces without compromising performance.
• Seamless Compatibility: Designed to fit standard mounting brackets and drive shaft configurations found in many compact cars, ensuring a straightforward replacement process.

Installation Overview

Replacing the Airtex 1850 Water Pump involves a series of precise steps that should be followed carefully to maintain system integrity:

1. Drain the Coolant System: Safely lower the coolant reservoir and remove any remaining fluid from the radiator.
2. Disconnect Electrical Connections: Detach any sensors or wiring harnesses attached to the pump housing.
3. Remove the Old Pump: Unbolt the existing water pump, taking care to keep the drive shaft intact. Note the orientation of the gasket and seal for correct reassembly.
4. Prepare the New Pump: Apply a fresh gasket or sealing compound as recommended by the manufacturer. Align the mounting holes with the engine block.
5. Install the New Pump: Secure the pump using the original bolts, tightening to the specified torque settings. Reconnect any electrical components.
6. Re‑fill and Test: Fill the cooling system with fresh coolant, purge air pockets, and run the engine to verify proper operation and absence of leaks.
