The Expansion cap is found on top of a plastic bottle in the engine bay. Never remove the cap from a hot engine, the cap may 'fly off' on releasing and hot coolant will burn your hand, if you must remove the cap, cover the cap with a suitable cloth, screw the cap slowly to release the pressure, then carefully remove the cap, do not put finger in hot coolant.

If the fan comes on when if feels like or the temperature gauge appears faulty, the Water temperature sensor may be faulty. We have also listed picture(s.
