Following up on my earlier post, I did get the radiator changed and it cleared up the leak at the front of the engine. (Dodge Caravan 2006 SXT, 125000 approx.). But I have a leak on both sides of the lower intake manifold. Coolant is at the bottom of the manifold, and appears every few days. I suspect manifold and have added a few pics to get your opinion. Thanks!

 

Looks like you are going to do an intake manifold gasket replacement soon.
Monitor your coolant levels to see if its going down faster than the leak indicates to see if its being taken into the combustion chambers. I don't think o2 monitors like it very much.

Make sure if you have not done so already to get the correct MFG recommended formula antifreeze. Among some of the issues with using the wrong antifreeze gasket material compatibility is one of them.

While your in there look at your injector harness. Do a search for it anywhere or look for a post made by me.
You will have access to the o2 sensor too.

Good luck and iot you are doing the work we would enjoy pics.
