Installation
⚙ Difficulty: Beginner | Time: 5–10 minutes
-
Cool the engine fully – Allow at least 30 minutes after shutdown. Never open the cooling system on a hot engine.
-
Locate the expansion tank – Typically positioned in the engine bay on the driver's or passenger's side; consult your owner's manual if unsure.
-
Remove the old cap – Turn anticlockwise slowly and lift away. Note the position of any seals.
-
Clean the filler neck – Wipe with a clean, lint-free cloth to remove any debris or old rubber fragments.
-
Install the new cap – Align the cap and turn clockwise until snug. Do not over-tighten—firm hand pressure is sufficient.
-
Start the engine – Run for 2–3 minutes and check for any leaks around the cap. Top up coolant if necessary once engine cools.
-
Monitor coolant level – Recheck after your first drive to confirm the seal is holding pressure correctly.
⚠ Important: Never remove the cap from a hot cooling system. Pressurised coolant can cause severe burns. Always wait for the engine to cool completely. If your cooling system overheats repeatedly after cap replacement, have a mechanic inspect the radiator and thermostat.
