Hi,

I attached a picture below of the hoses related to the engine cooling system. If you have a leak from the reservoir, the one hose runs to the upper radiator hose. It could be leaking at that point. See pic below.

Also, if you haven't already, I recommend pressure testing the cooling system. When the engine is cold, make sure the coolant is full, and then, using a pressure tester, pressurize the system. If there is a leak, you should be able to locate it when it is pressurized.

Here is a link showing how it's done:

I hope this helps. Let me know what you find or if you have other questions.

Take care,

Joe
