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.

Hi All,
Had a very immediate radiator failure and local garage ordered and fitted a new rad.
Unfortunately despite a few short drives there appears to be an air lock in the system and garage is struggling to get rid of air in the system.
They are leaving it overnight to hopefully settle down and with bleeder valve open to release any locked air pockets, but is there some other trick they are missing?
I admit they are not a porsche specialist, but very practical given radiator dumped less than a mile away so went straight there.
Thanks in advance,
Steve
they are very difficult to bleed without a vacuum tool. but i think there is an alternative procedure where you need to raise the rear of the car as much as possible...
The bleeder valve won't do anything without the engine running. I would leave it open for a few days after a coolant change or top-up anyway.
As said, a vacuum fill tool isthe best thing to use. The old method was basically to rev it up for short bursts several times, an keep topping up as the air circulates. Jetbox is correct that it also helps tp get the rear end up in the air.
When i had my header tank changed, everytime i went to/from work i just crackedthe lid off a bit to relieve some of the pressure . I think its got rid of all the airlocks now.
Richard to the rescue as normal...
The manual engine revs (reving to 5000rpm) appeared to do the trick and engine ran at normal temperature all day today - spot on the middle of the '0' of 90 degrees on dash although having used it today I have loosened off the cap as per thread recommendations.
Is it worth leaving cap off for a few days for remaining air to get out if i am not using the car? i assume a damp night won't be an issue?
Thanks, Steve
