I intend to pressurise the system to 20 psi to see if I can spot the source and as it looks like a very awkward job to replace the entire aluminium section, I was considering replacing only the leaking piece with some hose and clips.

I cut the piece out with a small tube cutter and after cleaning up the ends I used a smear of Loctite sealant on the pipe ends before clamping up with stainless hose clips.

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

Hi, I noticed a small deposit on the garage floor at about the position of the front of the gearbox and towards the nearside, seemed to be like a light oil!! I have now put it on stands and I can see a drop of liquid on an aluminium pipe which comes from the top of the coolant header tank and which eventually disappears forwards. Pipe dia. approx 1/2 inch presumably a vent pipe? Can only be a coolant leak but very minor at this stage. No obvious damage to the pipe but it must be pinholed somewhere. I intend to pressurise the system to 20 psi to see if I can spot the source and as it looks like a very awkward job to replace the entire aluminium section, I was considering replacing only the leaking piece with some hose and clips. Has anyone replaced this pipe in situ? Best regards.

POST 2Original post

I had this problem recently, also a 2004 cab by coincidence? Replacing the entire pipe looks like a complete PITA and the most likely place for a hole is at the metal clip on the vertical section. I cut out a section from above the clip on the vertical piece to an area on the flat where I could get a straight section and then inserted a piece of appropriate hose. I cut the piece out with a small tube cutter and after cleaning up the ends I used a smear of Loctite sealant on the pipe ends before clamping up with stainless hose clips. No problems so far after approx 1k miles.

POST 3Original post

To replace that pipe is an engine out job .. there is a metal bracket that locates it halfway up on the chassis .. steel and ally .. sigh .. common for them to corrode at that point . I've only ever replaced these pipes .. if a cut and join can be done as per ian_alex post then it will save you a fortune .. Manual engine R&R is 8 hours labour .. Tip and closer to 13 ... plus pipe replacement .
