C4Ss do not have the 3rd radiator from the factory, even for the tips, or X51 I'd pull the bumper and check your lines.
Leading evidence: 'Check lines' (no explicit attributable resolution; this is a reported action or suggestion).

My local dealer is closed at this time and i'd like to check on-line to get an idea of cost.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have been noticing a small amount of coolant on the driveway the past few days. I thought it was in the in-laws car until I parked it in the garage and noticed some on the floor from under where the passenger front tire/bumper would be.
I took it to work and placed it on a lift. Definitely have a coolant leak coming from the passenger side upper radiator area. Pressurized the system but it was hard to tell where the leak was coming from with out taking off the bumper, which I have not done yet. Strangely enough there also seemed to be a small amount of coolant dripping from under the drivers side bumper(just in front of tire). It's obvious that there is a radiator inside the bumper on either side but apparently there is a third radiator as well which I could not find(again, without removing the bumper).
I searched for threads regarding this topic but nothing similar. The car is an '03 c4s. Is the 3rd rad. located in the center, behind the bumper and is it possible or more common for this to leak than for both outer rads to leak, at the same time? I'm starting to think that coolant is just traveling down the lines and it just appears that the the outers are leaking.
Any thoughts?
Removing the bumper in order to make a proper diagnosis is probably not a bad idea. Do a search here or on renntech.org for instructions. It's not THAT difficult.

Some auto parts stores sell a die that shines under black light. I've used it for a/c and it works for radiators, trans and oil too. The service manual should show you what's in there and how to get at it. Normally lines and radiators don't care where they leak as long as they can do it. You have to be in there to know.
If it has been freezing and your fluid isn't up to snuff then it is best to get things right so that freezing doesn't cause any problems. Keep an eye on the actual radiator level instead of just the overflow. Radiators can feed the overflow then hose leaks cause the radiator to just suck air back in instead of water. Thus steadily you get more and more air in the radiator. Not good.
Removed the front bumper and unfortunately both rads are leaking. Does any one know the part #s for the 2 radiators? Any good after market replacement parts? My local dealer is closed at this time and i'd like to check on-line to get an idea of cost. Thanks.
