Question about 2003 Volkswagen Passat
Have the cooling system checked,see if the coolant level is low,also,if it is have it pressure tested to see if there is a leak,water pump,coolant sensor and radiator along with the thermostat ,have a lot to do with the cooling system performing correctly ,along with the cooling fans.All these have to be working correctly to achieve a 1 performance from the cooling system.Air in the cooling system will cause this situation also,and is associated with coolant loss.Look for leaks,and see if the cooling fans come on,at idle on there own,and go off by them selves,just make sure the ac is off,because the ac turns the cooling fans on automatically.First thing for you to do,is fill the reservoir to full,and start and let it get to normal operation temp,and the cooling fans come on,then they will go off,see if it does this.
