Hi. Two week ago my coolant started to leak, not a major leak. Lifted the car and could not locate where it coming from. When the car is runnig or warm there is no leak. It only leaks when the engine cold. Any suggestion??? checked all the hoses, and they seem to be fine.

 

Most common leak is the coolant flange. Look at the transmission bell housing from the passenger side of the engine bay.

 

I am having the same problem. Is your leak coming from the back side of the engine?

 

Yes, Or the rhino plug or nipple.

Flange is against the firewall, rhino plug is in the thermostat housing, and the nipple is under the engine cover on the coolant pipe
