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.

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

POST 1 / ORIGINAL POSTEROriginal post

Ive noticed a little coolant in the top on the reservoir. I'm thinking the cap is letting some get out. Running temps are normal. I ordered a new one. Was wondering if they tend to go as radiator caps do with age and wear? Mine goes on not so easily and If I hand tighten it, I see more seepage. I usually use a strap wrench to get it good and snug.

POST 2Original post

Hand tight should be fine. There were several superceded P/Ns on this cap, get the newest one and all will be fine...until the next updated one anyway.

POST 3Original post

i had a similar issue, had mine replaced under warranty with a Newer Part, 99610644704 get it at Suncoast Parts for $15 or at your Local Dealer for $23

POST 4Original post

Yup, your part # probably ends in "0" or "1", the newest end in "4". The zeros leak at will.

POST 5 / ORIGINAL POSTEROriginal post

Thanks guys! I ordered mine from pelican. I hope it's the newer one! Just checked my receipt and it's the newer one ending in 4! Cool!

POST 6Original post

One of the worst designed parts on these water cooled '911s' is the radiator cap (coolant cap). I have gone through 3 in 50,000 miles (4 years) of service. All have been replaced under warranty so far.
