OK guys, I got a call from my mother. The dashboard of her Renault Kangoo '07, 1149cm³, 55kW shows Aladin's wonderlamp [sic!], the temperature bar is at 100%, and a word, "STOP" appears.
I've had a look now, the car was cold and temperatures here are near freezing.
The coolant reservoir was completely dry, so I topped it off.
It seemed as if no coolant flew into the system, just as if the level was just below the reservoir. Yet, the level sank within 20-30 minutes of idling, and I filled in a total of about 2l.
The car doesn't loose coolant, it doesn't burn it, and there's also no coolant in the oil.
When the temperature gauge shows about 50%, the fan is switched on, as expected, but the gauge went higher and higher.
The radiator as well as the upper hose to the radiator stays cold, while the upper hose to the reservoir, which branches from the upper radiator hose near to the motor, becomes very warm. But it doesn't spill coolant into the reservoir, just steam. Further more, the heating blows cold air, only.
So, I'm quite confident the water pump isn't working since the heating stays cool, too.
- Is it normal that the water level falls so slowly?
- How easy is it to replace the pump? There are models with the pump at the normal belt, others have it at the timing belt... I couldn't have a look there up to now and would like to know what to expect.
- May be, how much coolant is in the system?
