I just got done replacing the thermostat and water pump with gaskets and now my thermostat is leaking and there's a slight leak on the water pump.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

99 996 C4 83k miles, water pump was shot and LEAKING so I replaced it and went ahead and replaced thermostat as well. I just got done replacing the thermostat and water pump with gaskets and now my thermostat is leaking and there's a slight leak on the water pump. Did I just not install them correctly? if so may I get some advice, or is there another problem. Here is the link to the video for more context, the short video is before the replacement and the long video is after the replacement. https://drive.google.com/file/d/1lkR...ew?usp=sharing https://drive.google.com/file/d/1jHP...ew?usp=sharing

Did you replace the gaskets? What brand water pump and thermostat?

POST 3Original post

So, I had a similar situation when one of the tabs on the water pump gasket had partially folded on to itself. Hard to explain but basically the tab was a "C" shape instead of an "O". Everything was tightened to spec but the double layer effect created enough gap to cause a leak. In your case I would just go and ensure each bolt is tight to spec. Maybe something got missed? Otherwise I think next step would be pull everything off and re-seat?
