Installation instructions:
✅ 1. Clean the contact surfaces: Before installing the gasket, thoroughly clean the contact surfaces of the water pump and engine housing to ensure the following: • No oil, dust, or sealant residue. • Remove residue with a clean cloth or scraper, then wipe the surface dry and residue-free with a degreaser.
🔹 Purpose: Prevent leaks and ensure proper sealant adhesion.

✅ 2. Apply RTV engine sealant evenly • Apply a thin, even layer of RTV engine sealant to both sides of the gasket. • Avoid applying excessive sealant, as this may cause the following: • Poor sealing • Sealant overflow, making later disassembly difficult.
🔹 Note: Use specification-compliant RTV sealant to ensure high-temperature resistance, leak protection, and long-lasting sealing performance.

✅ 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 this may cause the following: • Damage to the gasket • Deformation of the contact surface, compromising the seal.

✅ 4. Curing time • Allow the sealant to cure undisturbed after installation. • Follow the sealant's curing-time instructions to ensure optimal sealing performance before starting the engine.

🔹 Tip: Avoid moving or disassembling the 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 fumes. • Use a special cleaner or alcohol to remove excess sealant and keep the contact surface clean.
