I have had a leak on my E250 saloon 2009 for a while. The car has not been driven since the leak discovered. Can anyone tell me the path that coolant liquid takes after you put some into the expansion tank. Within a minute or so it's pissing out from under the the engine somewhere. What could...

Hello The 'check coolant level' light came on earlier a few miles from home. I've let the car cool and I've had a look at the tank. I've included a picture of the current level. Can't see any signs of leaks, it's parked on a rather clean driveway so it would show pretty quickly. Does the tank...

just started my 2003 sl55 after a couple of months and there is a slight water leak appears to be coming from a small pump type thing in front of the drivers front wheel. its definatly coolant. anyone know what it is ?

Is there a specific coolant that is better for your car rather than using water? I believe i've seen some people using a bright green liquid. Anyone know what it is and weather it makes a difference?
