I have a 2002 Pathfinder SE. 3.5v6. I have recently replaced the radiator & hoses. But I am getting a small drip that appears to be coming from somewhere at the back of the engine. The drip is appearing at the back of the Oil pan. Like the fly wheel/trans connection area. I have tried to look down behind the intake and from the sides of the engine but cannot see where it might be leaking.

Any ideas where this leak could be coming from?

Thanks!

I'm not sure about the 3.5L but my 3.3L has 2 small coolant hoses at the back of the engine towards the passenger side and a couple more under the intake manifold.

Welcome to Nico!

You're not going to want to hear this since it's kind of a spendy/difficult fix, but it's probably one of the gaskets on the crossover tube, based on the region of the leak. You should be able to get an extendible mirror and confirm where the drip is coming from (the engine probably needs to be hot or running for it to be dripping).

Take a look at that link and see if it sounds like what you're seeing.
