Oversized Water Pump Impeller Radiator Kit for KTM 450 500 EXC-F/XCF-W Husqvarna 450 500 FE/FX 17-24 Gas Gas 450 MC F/ EX F/EC F 21-24

Features:

• Faster Cooling – Enlarged impeller blades allow more coolant to flow through the water pump at the same motor speed. Reduce coolant temperature by 10–15 degrees compared to the standard and optimize your motorcycle’s overall performance.
• Increased Capacity – The aluminum spacer increases the total volume of coolant flowing through the water pump, improving heat exchange.
• Lightweight Aluminum – Made from high-quality 6061-T6 aluminum, offering superior hardness with minimal weight.
• Racing Look – Processed with advanced anodizing to preserve the original appearance over time and enhance the motorcycle’s character.
• CNC Technology – Thanks to the latest CNC technology, the precision of each machined part is ensured for easy installation.

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 prevent sealing defects 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: • Poor sealing • Sealant overflow leading to difficulties during later disassembly.
🔹 Note: Use specification-compliant PTV sealant to ensure high temperature resistance, sealing protection, and lasting sealing performance.

✅ 3. Proper installation and tightening • Align the gasket with the applied sealant precisely 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: • Damage to the gasket • Deformation of the contact surface, impairing the seal.

✅ 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.
