Design & Engineering Excellence

The pump’s architecture incorporates a precision‑machined impeller that maximizes flow rate while minimizing turbulence. The housing is engineered to withstand high pressure differentials, ensuring consistent coolant delivery even under extreme thermal loads.

Impeller Technology

The cast‑iron impeller features a multi‑stage blade design that enhances volumetric efficiency. Its geometry reduces cavitation risk and extends service life by maintaining uniform flow across the pump’s operating range.

Casing & Sealing

A robust casing protects internal components from coolant contamination. The pump employs high‑temperature silicone seals that resist degradation, providing long‑term reliability without frequent maintenance.

Performance Characteristics

• Flow Rate: Optimized for engines requiring up to 3 L/min of coolant circulation.
• Pressure Head: Maintains a stable pressure differential across the radiator and heater core, ensuring efficient heat exchange.
• Operating Temperature Range: Designed for coolant temperatures between 80 °C and 120 °C.

Installation Guide

Installing the Airtex 1817 Water Pump is straightforward when following these steps:

1. Disconnect the battery to prevent electrical hazards.
2. Drain the coolant system completely.
3. Remove the old pump by loosening the mounting bolts and disconnecting the drive belt.
4. Install the new pump, ensuring proper alignment of the impeller shaft with the engine crankshaft pulley.
5. Tighten mounting bolts to the manufacturer’s specified torque.
6. Reinstall the drive belt and re‑fill the cooling system with fresh coolant.
7. Bleed the system to remove air pockets, then test for leaks and correct operation.
