Water pump cooler impeller spacer for KTM 690 Enduro SMC R DUKE 2008-2023

Original plastic impellers deform under heat. Our CNC impeller made from aircraft-grade aluminum is extremely durable and corrosion-resistant. With larger blades and a raised base, it ensures better coolant flow, faster cooling, and optimized heat exchange.

Features:

• Oversized impeller and raised base – Enlarged impeller blades are designed to deliver more fluid at the same engine speed, achieving faster cooling. A spacer is included to accommodate the blades, which is installed between the engine block and the water pump cover. The raised base of the impeller also facilitates coolant momentum, maximizing flow rate and improving heat exchange. The improved impeller profiles prevent unpleasant cavitation that would lead to efficiency loss.
• Aluminum spacer – The aluminum spacer increases the heat dissipation surface, effectively preventing overheating and reducing the activation of your radiator. Combined with the aluminum spacer and improved impeller, your motorcycle’s potential can be fully utilized.
• High-hardness blades – The stock impeller is made of thin plastic that easily deforms over time at high temperatures, causing friction against the water pump cover. Our product is made from billet aircraft-grade aluminum, extremely durable and corrosion-resistant.
• Dynamic look – Anodized surface for enhanced aesthetics and rust resistance. Ride your beloved bike with pride.
• CNC technology – Manufactured with the latest generation CNC technology to ensure high precision for a perfect fit.

Installation instructions:
✅ 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 residues. • Remove residues with a clean cloth or scraper and wipe the surface dry and residue-free with a degreaser.
🔹 Purpose: To avoid faulty sealing and ensure sealant adhesion.

✅ 2. Apply PTV engine sealant evenly • Apply a thin, even layer of PTV engine sealant on both sides of the gasket. • Avoid excessive sealant application as it can cause: • faulty sealing • sealant overflow, making later disassembly difficult.
🔹 Note: Use specification-compliant PTV sealant 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 the screws according to the manufacturer’s torque specifications to ensure even compression.
⚠️ Caution: • Avoid overtightening as it can cause: • gasket damage • deformation of the contact surface, impairing sealing.

✅ 4. Curing time • Allow the sealant to cure undisturbed after assembly. • Follow the 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 installation to avoid skin contact with the sealant. • Work in a well-ventilated area to avoid inhaling volatile gases. • Use a special cleaner or alcohol to remove excess sealant and keep the contact surface clean.
