Installation Guide (Step‑by‑Step)

1. Preparation: Disconnect the battery and drain the cooling system to avoid spills. Wear protective gloves and eyewear.

2. Remove Old Thermostat: Locate the thermostat housing beneath the radiator or engine block. Unscrew the mounting bolts, carefully detach the old unit, and note the orientation of the O‑ring for correct reassembly.

3. Install New Unit: Place the new Febi Bilstein 04755 thermostat into the housing. Align the O‑ring with the gasket slot to ensure a tight seal. Tighten bolts to the manufacturer’s torque specification (typically 10–12 Nm).

4. Refill Cooling System: Reconnect coolant lines, refill with appropriate coolant mixture, and purge air by running the engine with the heater on high.

5. Check for Leaks: Inspect all connections after a short test drive. No leaks should be present if the O‑ring is seated correctly.

Maintenance Tips

• Inspect the thermostat housing gasket annually; replace if cracked or worn.
• Use a high‑quality coolant that meets OEM specifications to prevent corrosion and scale buildup.
