Water Pump Impeller Spacer for Husqvarna 701 Enduro Supermoto 2016-2023

Stock plastic impellers deform when encountering heat. Our aircraft-grade aluminum CNC impeller is extremely strong and corrosion-resistant. With larger blades and increased base, it provides better coolant flow, faster cooling, and optimized heat exchange.

Features:

• Oversized Impeller & Raised Base - Enlarged impeller blades are designed to shed more fluid at the same engine RPM, achieving faster cooling. To accommodate the blades, a spacer is included, to be installed between the engine block and water pump cover. The impeller's raised base also facilitates the impulse of the coolant, maximizing the flow rate and improving heat exchange. The improved impeller profiles avoid unpleasant cavitation that would result in loss of efficiency.
• Aluminum Spacer - The aluminum spacer increases the heat dissipation surface area, effectively preventing overheating and reducing your radiator’s activation. With the combination of aluminum spacer and upgraded impeller, your motorcycle's potential can be maximized.
• High-Hardness Blades - The stock impeller is made of thin plastic which easily deforms over time in high temperatures, resulting in friction with the water pump cover. Our product is made of aircraft-grade billet aluminum, extremely strong and corrosion resistant.
• Dynamic Look - Anodized surface for enhanced aesthetics and rust resistance. Ride your beloved bike with pride.
• CNC Technology - Cut with the latest generation CNC technology, they ensure high accuracy for a perfect fit.

Installation Instruction:
✅ 1. Clean contact surfaces: Before installing the gasket, thoroughly clean the contact surfaces of the water pump and engine casing to ensure: • No oil, dust, or sealant residue. • Remove any residue with a clean cloth or scraper, and wipe the surface dry and residue-free with a degreaser.
🔹 Purpose: Avoid poor sealing and ensure sealant adhesion.

✅ 2. Apply PTV engine sealant evenly: • Apply a thin, even layer of PTV engine sealant to both sides of the gasket. • Avoid excessive sealant application, as this can lead to: • poor sealing • sealant overflow, making future disassembly difficult.
🔹 Note: Use PTV sealant that meets specifications to ensure high-temperature resistance, leak-free performance, and durable sealing.

✅ 3. Proper installation and tightening: • Precisely align the gasket with the applied sealant between the water pump and engine. • Tighten screws according to manufacturer's torque specifications to ensure even compression.
⚠️ Caution: • Avoid overtightening, as this can lead to: • gasket damage • contact surface deformation, impairing sealing.

✅ 4. Curing time: • Allow the sealant to cure undisturbed after installation. • Follow sealant instructions for curing time to ensure optimal sealing performance before starting the engine.
🔹 Tip: Avoid moving or disassembling parts during the curing process.

✅ 5. Safety instructions: • Wear protective gloves during assembly to avoid skin contact with sealant. • Work in a well-ventilated area to avoid inhaling volatile gases. • Use a specialized cleaner or alcohol to remove excess sealant and keep the contact surface clean.
