Coolant warning light in instrument cluster

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

In order to prevent excessive engine coolant temperature, make sure that the cooling-air ducts are not obstructed by coverings (e.g. films, stone shields). Leaves and insects on the radiator condenser fins can be vacuumed off or removed using a high-pressure cleaner.

Four functions of the coolant warning light:

Engine coolant level too low
- light flashes slowly (0.5 Hz)
Engine compartment temperature too high
- light flashes slowly (0.5 Hz) (engine compartment blower might be faulty)
Engine coolant temperature too high
- light is lit; pointer on the right
Temperature sensor at water outlet faulty
- light flashes rapidly (1 Hz); pointer on the right
NOTE:
- The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously.
