Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that suspect a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suspected cause
If there is water in the tray around the coolant cap, which exits through a rubber tube on the tray, then it is probably the cap blowing off at too low a pressure.

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 guys, i topped up my coolant to the min last night and tonight on my way home the little red light started flashing again. When i got home i popped the boot to check the level and it seems to have dropped out of the main resevoir bit of the header tank. Is this normal when its been heated up? Oh ishould mention its either a 00 or a 01 cap but ive got the latest revision due to be delivered on friday.

POST 2Original post

Any traces of water on the engine compartment just under the coolant tank? If so, the tank might have cracked or pinholed, which is very common. If there is water in the tray around the coolant cap, which exits through a rubber tube on the tray, then it is probably the cap blowing off at too low a pressure. Were you giving it some beans? That's when it usually happens

POST 3 / ORIGINAL POSTEROriginal post

Yea i was a bit i thought it seemed to drop quite quickly.

POST 4 / ORIGINAL POSTEROriginal post

Hi guys, further to my last question on coolant leaks i took my car in for a service at porschtek (very good job btw) and when it was up on the ramp and noticed that the coolant leak is from a plate on the bottom of the engine. I would post a picture but its in the middle of the car so hopefully someone will know what im on about. Apparently theres a newer revision with a better seal so i was thinking of changing itmyself is this possible?
