I filled it up with a bit of distilled water when I replaced the cap a week ago or so.
Leading evidence: 'Replace cap a week ago or so' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'cracked tank' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Recommend levels' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suspected cause
If it gushes out while sitting after a good run while still hot (heat soaking) it is most likely a cracked tank.

Suggestion · Original poster
If you overfill will it not simply dump just enough fluid to bring it back to the recommended levels?

I refilled some distilled water to see if it was only a problem when running/pressurized.

Suggestion
Some have success using a mirror, but didn't work for me.
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.

Hello,
I went out for a drive this morning with no problems. I parked the car at home, went to get a coffee and noticed liquid on the ground next to the rear passenger wheel. I felt and smelt the liquid, clear but somewhat oily. It seems to be coming from the rear driver's side, below the coolant tank (I know these are prone to failing). I opened the engine compartment but couldn't spot any obvious leaks from the tank (hard to are the portion closer to the front of the car). Could this be water shaken loose from some cavity as I was driving? We usually get quite a bit of condensation in the mornings. I attached a photo where you can tell where the drip is coming from. Thanks in advance.
Kromdom,
Thank you for the advice. I have the new 04 cap. Other than the tank itself, could it also be from the overflow escape hose? I filled it up with a bit of distilled water when I replaced the cap a week ago or so.
Is the cap on TIGHT...read TIGHT? Any liquid beneath the cap on the tank neck? It can drain down around, I believe, #1 cylinder. Almost impossible to see a tank leak. Some have success using a mirror, but didn't work for me. Cracks seem to be always on the back side.
It was my first drive after installing the 04 cap. Cannot help but think that the added pressure caused by no leakage at the top may have caused the failure. Oh well.
Thank you for the tip. It was really gushing out. I refilled some distilled water to see if it was only a problem when running/pressurized. So far it seems to be holding when cold.
If you overfill will it not simply dump just enough fluid to bring it back to the recommended levels? Or is it more of a uncontrolled, overpressurized, dump until pressure equalizes situation?
Thank again
Mostly your second stated option. And even when it equalizes pressure it may do it again until there is enough airspace in the tank to act as a buffer. My 2003 C2 was happy with the tank ~1\2 full when cold the 04 turbo settles at~2/3. Both hit MAX line when hot.
fpb111: I appreciate your insights. I will start it up with and go for a slow ride while monitoring the temperatures. I don't want overheat/warp anything in the engine, but unfortunately it is very hard to read the min-max with the cap on. Would this be safe or is it advisable to just have it towed to a shop?
Thanks again
Sure if you think it is something catastrophic take it to a mechanic. You might be over reacting. If it gushes out while sitting after a good run while still hot (heat soaking) it is most likely a cracked tank. Buy a new tank and swear it in ...I mean replace the old one.
I took it for a quick spin yesterday. No apparent leaks. Seems the coolant settled at the min line. Will continue to monitor it and see how it goes. Would rather spend those dollars on gas 🤠
