Airtex 7115 Water Pump

Airtex 7115 Water Pump

The Airtex 7115 Water Pump is a high‑performance cooling system component engineered for durability and reliability in automotive applications. Designed to fit a wide range of vehicles—including Hyundai Getz, Mitsubishi Colt, Proton models, and many others—this pump delivers consistent coolant flow while withstanding the demanding thermal and mechanical stresses typical of modern engines.

Key Design Features

• Robust Construction: The pump body is fabricated from hardened steel alloy, providing resistance to corrosion and wear. Its sealed impeller design prevents coolant leakage and protects internal components from debris.
• Efficient Impeller Geometry: A precisely engineered impeller ensures optimal pressure generation, maintaining steady coolant circulation even at high engine temperatures.
• Sealed Bearing System: The pump incorporates a sealed bearing assembly that eliminates the need for external lubrication, reducing maintenance requirements and extending service life.
• Compact Footprint: With dimensions tailored to fit tight engine bay spaces, the Airtex 7115 can be installed in vehicles where space is at a premium without compromising performance.

Compatibility Overview

The Airtex 7115 Water Pump is compatible with a broad spectrum of vehicle models. Below are some of the primary applications:

Technical Specifications

• Shaft Length: 140 mm (adjustable via extension shafts for specific vehicle configurations)
• Mounting Flange: Standard 90° angle with 4‑bolt pattern
• Impeller Diameter: 30 mm
• Operating Temperature Range: -40 °C to +120 °C
• Material: Hardened steel alloy with PTFE coating on impeller blades for reduced friction
• Seal Type: Dual O‑ring seal system (silicone and EPDM) ensuring leak‑free operation

Installation Guide

1. Preparation: Disconnect the battery, drain the coolant reservoir, and remove the existing water pump if replacing.
2. Mounting: Align the new Airtex 7115 with the engine block’s mounting flange. Secure it using the supplied bolts, tightening in a cross‑pattern to ensure even pressure distribution.
3. Shaft Connection: Attach the pump shaft to the engine crankshaft pulley or accessory drive gear. Verify that the shaft is fully seated and free of wobble.
4. Seal Installation: Apply a thin layer of high‑temperature silicone grease to the O‑rings before seating them on the flange to prevent premature wear.
5. Coolant Refill: Refill the cooling system with the manufacturer’s recommended coolant mixture. Bleed air from the system according to vehicle service procedures.
6. Testing: Start the engine and monitor for leaks, abnormal noises, or temperature irregularities. Allow the engine to reach operating temperature and confirm stable coolant flow.

Maintenance Tips

• Inspect the O‑rings every 12 months; replace if signs of cracking or hardening appear.
• Check for coolant leaks around the pump housing during routine service intervals.
• Ensure that the radiator and heater core are free from blockages to maintain optimal heat exchange.
• Use only approved coolants that meet the vehicle’s specifications to avoid corrosion or scaling inside the pump.

Performance Benefits

The Airtex 7115 Water Pump delivers:

• Consistent Coolant Flow: Maintains engine temperature within safe limits even during high‑load operation.
• Reduced Noise Levels: Sealed bearing design minimizes vibration and acoustic signatures.
• Long Service Life: Hardened materials and sealed construction reduce wear, extending the pump’s operational lifespan.
• Easy Replacement: Standard mounting dimensions allow for straightforward swap‑in/out procedures without extensive modifications.
