I have a 2004 4.0cyl that has an apparent slow radiator leak however I cant seem to find the leak. Are there any problem or known issues with the radiator on these models where a leak might be?

I think its where the top hose mounts to the block, maybe the gasket -- at least I hope. I've attached a few pictures if anyone could help it would be appreciated.

Also if it is the spot in the picture, I would assume replacing that gasket is fairly straight forward?

The plastic thermostat housing leaks. I had to clean my engine within an inch of its life, blow dry it with a wet&dry vac, and watch for 90 minutes to see the yellow water rise up around a bolt. You can do the work to find the leak or just slam a new thermostat housing in.
 






I was told to keep a housing in my truck....that's how bad of an issue it is evidently.
 






Thanks for the help guys, looks like I will pick up a housing and replace this weekend.:bow:
