Hey all. So finally everything lined up today for me to look for my coolant leak. Laziness was my biggest problem. Anyways any one have any hints as to where the leak is? I couldn't really tell, and am not familiar with the coolant system. I have never changed a thermostat. That's why I am on the newbie forum. Any ideas?
Here is the top of one of the sensors: There was coolant on the bottom and the cable looks a little bulged.
The view from the front:
Some background: I have to refill the reservoir every week or so. I had my mechanic flush by system a while ago and this problem seemed to happen at the same time. Seems to be getting worse.
Also any ideas what is going on here:
I think my AC is leaking, but I am not sure what those things are.
Yeah the thing is I couldn't see very well, too much stuff in the way. I guess the suggestion would be to start tearing some stuff off and having a better look? Once I start pulling the intake manifold I will need to replace the gaskets right?
rich uncle - you're best bet right now - other than taking it back to the mechanic that did the flush - might be to wipe off all the visible coolant from your engine, and then start the car and watch to see where it is coming from. It is not possible to determine where it is leaking based on these photographs.

Thanks for the ride !
Thanks for the suggestions. I would take it back to my mechanic but I moved.
I will take a better look this weekend. I was just checking to see if it was an obvious problem. Like "oh you have liquid in that area, it's most likely ...". I will let you guys know how it goes.
Ya, try tightening the clamp on that hose for the sensor and see if the leaking stops. You can go real tight on those hose clamps. Pour some water around the area to get the coolant that is there out so you can see if it comes back after tightening the clamp. Maybe the guy used that hose to flush the system?
As for the AC, clean off those areas with some gunk cleaner or something that removes grease, have the pressure of the AC system checked and see if it lost coolant and if the leaking persists (after cleaning the lines).
well I tightened the hose clamp and it still leaks. I think it leaks where that tube connecting to the manifold.
I was at a pull a part for an unrelated thing and I saw a 3.8L in a mustang with the same tube (the one with the sensor on the top and the line going to the heater core). I could not for the life of me get that thing off. I didn't have the right tools though...big leverage pipe, hammer, etc. Then I figured "what am I doing maybe I should just take the whole manifold. Well, I was a little in over my head. I got stuck at the fuel rail and figured I took too much time and left it.
oh by the way, just curious..lets say i needed to replace the flexible piece of hose that runs from the tube to the hard line going to the heater core. Would I need to replace the hard line to?
