Hi Guys,

I am losing coolant and have to top up about every week. There is a puddle below the area around the expansion tank.

What is weird, that this only happens when I go for a short < 10 minute ride and stop the car. If the car is really hot, I would not see any water dribbling down there.

When I looked in the engine compartment I was not able to see any leak. But also had not the opportunity to open the bonnet when it happens. Jut hope its not the expansion tank himself.

The car is 4.4 2005.

Any clues?
