Its a plastic pipe (see pics) and when I fill the vehicle with coolant through the header tank it obviously circulates the engine and then comes straight out the pipe underneath - very strange as it looks like its supposed to be connected to another pipe.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hello, I need some help with coolant loss from a pipe in the middle of the car. Its a plastic pipe (see pics) and when I fill the vehicle with coolant through the header tank it obviously circulates the engine and then comes straight out the pipe underneath - very strange as it looks like its supposed to be connected to another pipe.

POST 2Original post

That looks like the air con condensate drain. If it is coolant coming out (should feel distinctly different to water - sort of slippery / slimy between your fingers) I suspect the heater matrix and this would be the first thing I would check out if it were my car.

POST 4 / ORIGINAL POSTEROriginal post

Thank you very much for the information. I just thought it was very strange for the coolant to come out there if the matrix had failed as it literally drains the engine coolant in a matter of minutes. Ill change the matrix and go from there I think. Appreciate your help. Andy
