Oil leaking under hood passenger side 2010 cadillac srx. Wont stop overheating.

If your engine is overheating, this is a primary concern; the oil leaks are an issue but not generally related to overheating. Testing is needed to see if you have a cooling fan issue, a coolant flow issue, a thermostat issue or some other engine issue for the overheating. Once that is resolved, then any oil leaks must be cleaned and dye added to your engine oil to pin point the source of the leak.
