Mechanic time?

Squeak- pull your inspection panel behind the seats and see if you can identify the source. Too much tension on the serpentine belt can cause water pump bearing failure over time. If the water pump or any of the idler pulleys turn with resistance, wobble, or noise they should be replaced.

Flashing Temp light- low coolant level or failed radiator fan motor.

Thanks! I'll be investigating this weekend while installing my new brake booster and changing my Audi's oil. Ohhh holiday weekends, I love you.

my sound is more of a "chirp" than a squeek.

it warmed up here recently and the sounds totally stopped.

i took the car out the other night and it was cold out - and I heard it a couple times. so I'm thinking it may be something temperature related???

where I live right now it's in teh 80-90s at day, but cools up to 60s at night... so big temp diff oin the evening... I mostly noticed the sound in cooler weather.. it's still very quiet.. but you heqr this chirp at very slow speed when I pull away and give it power.

Assuming this IS the loose spark plug problem - can I reach them all from the top of the car or do some need to be accessed from the bottom and can I do it with a standard spark plug socket or is there a special porsche tool for this?

I"ve taken the engine access panel off - that's no problem. I have repalced spark plugs plenty of times on OTHER cars...never did it on the boxster and honestgly don't even know if every single spark plug is easy to access..

before I go pull the cover off and try to tighten them all - i thought i'd ask here - is it relatively easy to get to all of them? i'm off of work this week so I've got time to look into it and try to fix it myself...

i'm also thinkign of tackling my window regularor...the driver's side is going bad...

Mine has access in the back tire wells, a small door panel. The access isn't the issue the plugs are very deep, you need a long extension and a flexible link, I also use a rubberized plug socket. Make sure to use extreme caution not to cross thread. Mine was making the noise, it has not since I serviced the plugs, I'm confident it will solve your problem.

is this sometehing I can realistically do m yself or would it be better to let my mechanic do it???

i'm going to take it in in the near future to replace my engine mount - uit's cracked and I have the 3k vibration....

maybe they can easily do this when it's in for the bearing?

I have no problem opening up the top and getting access but I only have basic hand tools..I have a large socket extension and the little flex thing that lets you go in at an angle... is that what you mean I need ??

or is there a special porsche tool / flexible socket attachment??

is the standard spark plug socket attachment the right one to get onto the boxster plugs? sorry if that's a stupid question but i've never even looked at mine...

I posted someone else's video/audio clip of spark plug chirp in the above post...

[23109VC]

okay, I listened to that sound file of the spark plug chirp..

my chirp noise sounds VERY similar to that one in terms of the actual noise - but the chirping in that video is 100x more prevalent than mine..the car in that video had nonstop chirping as it idled... my car ONLY makes ONE brief chirp at very low speed when I pull away from a stop or slow speeds...i hear a very brief "chirp" and then it's gone...

sometimes it doens't do it... but when it does chirp, you hear it..and I know it's therte..and it didn't use to do it..so something is worn / wearing out / such that it's making this intermittent chirp noise...

if my spark plug is "barely" loose..woudl it make tjhe sond only under certain conditions..such as mine..like pulling away from a stop... ??

and also - is thsi somethign I can fix witgh regular hand tools myself or do I need a mechanic with special porsche tools to tighten the spark plugs?

can all spark plugs be accessed from the engine bary or do you need to get at them from whels wells and remove the wheel liners??? thanks. i have no frickin clue how to get to them...
