Help with coolant leak

[BatMobile]

This car is really starting to give me a headache. Just finished replacing the DCCV, thermostat and hoses and now a whole new leak. I have no idea what this is coming from but was hoping someone on here may have a clue. If anybody has an idea please let me know 1st Gen, V6 - here are pics.

It seems to be coming from behind the piece in the first picture, with a couple close-ups on the other two.

It's coming from hairline cracks in your degas reservoir. (The thing with the radiator cap on it.) The only solution is to replace it.

Thanks. That's what I initially figured. But it just seemed to be coming from further back. The tank is a bit further to the right and the leak appears to be coming from directly behind the round apparatus. Everybody else on here mentioned having to replace the tank with the dccv and therm. but i was hoping not to have to do it. This is really adding up in cost now.

The "round apparatus" is the power brake vacuum booster. Three coolant hoses run behind (or actually above and below) the booster. One is the coolant feed to the car (comes from the bottom of the tank), one is the air bleed from the engine (goes to the top of the tank), and the last is the heater air bleed. The coolant feed hose and the air bleed hose come with the degas tank if you order it from Ford (Max is a good source for this). If you need the engine bleed hose (unlikely), you can just cut some hose to length from an auto store. I really don't think you're going to be the exception here, it's the degas tank. You just have a split that is facing the correct way to spray coolant behind the booster.

There is no particular reason to replace the DCCV when replacing the tank, unless your DCCV has failed already. The tank is pretty easy to replace, if you take it out with the bottom hose still attached. I did find that having some large hose clamp pliers and some large hose pliers helped.

Thanks. Just replaced the reservoir today. It had cracks all over the place. Actually much easier than I thought it was.
