Customer Question

I have a 2003 Mercedese SL500. I have coolent leak from the upper radiator hose after the car is shutt off. It is intermittent. I have tried replacing the coolant cap and changed the thermostat. But still leaks coolant from radiator hose. No oil in coolant. No white smoke when i turn the car on in the morning. I also changed the upper radiator hose once and changed the O ring inside. still get leak. any suggestions? I notice the radiator fan does not turn after the car is off. I dont know if that is normal on sl500. Radiator does work when ac is on.

Its it leaking from wear the hose hooks to the radiator or to the water intake valve

It sounds like you may have a hairline crack where the radiator hose hooks to the radiator my advice would be to get s tube of rtv silicone gasket maker and but all around it that will seal the crack and srop the leak
