Reported cause
My 986 (Boxster) threw coolant up all over pregrid at an autocross years ago; I was expecting the worst, but the issue was the original cap for the coolant tank wasn't holding pressure; the indy across the street loaned me a used cap until my new one from Pelican arrived.

I couldn't "feel" the AWD but it was rock solid and if anyone has traveled on I-40 through Tennessee can attest, it is quite twisty and had a lot of elevation change for a highway.

After about 30 times of doing this I give up and decide I will need to change my plans and spend the night in KC.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Edit: Glad you got it resolved and was fairly minor.
Hello, I have just sold my 964. I have to say that again, I have just sold my 964. Now that is out of the way, I am going to pick up my new to me 2003 C4S from Denver in Speed Yellow next week. I have owned a 73 longhood (silver), a 80 SC (Oak Green) and my 90 964 (Diamond Blue Metallic) so Speed Yellow is a bold step in terms of color for me.
My trip will be from Denver to Charlotte and exiting Denver I will head east on I 70 for a very long time until I hit St. Louis. I will then head southeast and point the nose of my 996 towards the Tail of the Dragon via Nashville. Lastly, I will go through Ashville and head east on I 40 to Charlotte.
If any of my new 996 brethren are along the route, feel free to PM me as if I have any issues, it would we good to reach out to the Rennlist community first for advise/recommendations.
And of course the obligatory picture of my soon to be C4S:
My new 996 C4S
Car looks great! Before you pay for it remove & inspect the oil filter for metal.
If you care anything about baseball see a game in St. Louis. Radar detector will pay for inself during the trip!
Are you saying that bcz of IMS issues? One of the selling points for me was all engine preventative maintenance was already performed. And the rear end, oh my!
It has been quite an adventure so far. I flew into Denver Tuesday morning and was picked up by the previous owner and transferred the title. A bonus was he has many of the service records and a new set of rotors packed up nicely for me. Who hoo, life is good! After trading history and Porsche stories, I was on my way headed east on I 70 by 10:30 AM.
First impressions are this is one amazing car. With the European sport suspension and the sport seats, this car is on rails and I stay planted in my seat very nicely. Granted I have only been able to do lane shifts up to this point. The interior is beautifully appointed with color matching belts and center console and the AC works, thank you Porsche!
Fast forward 8 hours and I am nearing KC and it begins to rain. With the AWD this Porsche is rock solid and I barely have to let off the cruise control that is set at 79. After a pit stop I decide to take a photo of the car with the rain beading off of the finish and low and behold, the front headlights don't come on. I panic for a moment and call the nearest Porsche Dealership in KC but of course, they closed 15 minutes ago. I emailed the previous owner and he suggests a fuse could be the culprit.
I hunt down the owners manual that is nicely packed in the glove box and my confidence is high right now. I pop open the fuse box area by the driver's foot and holly crap, there are like 60 fuses and no key to which ones are for what. I begin to take each fuse out to check and trying to remember exactly where they go back in. After about 30 times of doing this I give up and decide I will need to change my plans and spend the night in KC.
I make a reservation and also reach out to Jeff from the KC area that PM'd me. He has an indi he can recommend and we decide to connect in the AM. After a little internet searching I find Aristocrat Porsche in KC and low and behold, they are 10 minutes from my hotel. I show up right when they open at 7:00 AM and tell them my saab (I had a 99 turbo so I can say this) story. After a "we are really busy" they agree to get me in right away.
Apparently, there is a control unit behind the headlight switch that has a tendency to go bad. They had one in stock and I was back on the road by 10:00. A big thanks to Aristocrat Porsche for accommodating me and letting me get on my way relatively quickly.
Life is back in balance and point the nose towards the Tail of the Dragon!
I make it to a little town called Lenoir City, TN which is about an hour from the dragon. I wake up bright and early and head out and this sign puts a wide smile on my face:
The morning is warm and I have the windows down listening to the glorious sound behind me. The sun is just coming up and the experience is sublime.
At one of the pull off areas there is this sign that catches my eye: slay the dragon, not the bears. Okay, now I have to look out for bears, good to know.
After about ten miles of side to side g forces, I am ready to stop and enjoy the view. I get out of my car and this is what I see:
I quickly asses that this is steam, not mist from the morning....never a good sign. I stare at the engine lid for what seems like a long time but in reality is probably only 30 seconds befor it dawns on me I best turn off the car.
I now see that I have dumped my full reservoir of coolant onto the dragon...it is stained by my Porsche! Serves an air-cooled guy right, I am thinking. Welcome to water cooled Porsches!
I have my Porsche towed on a flatbed to Harper Porsche in Knoxville. Thankfully, my insurance company paid for the towing in full (they pay to closest dealer) and I am now in the waiting room, sitting nervously waiting for the prognosis. Meanwhile they buy me lunch and I have to say they have one of the nicest waiting areas (kind of out in the open, not tucked away somewhere). So thank you Harper Porsche!
Fingers crossed.
Hopefully just a cracked coolant tank; your blast along the dragon was enough to break the brittle-after-10-years plastic.
My 986 (Boxster) threw coolant up all over pregrid at an autocross years ago; I was expecting the worst, but the issue was the original cap for the coolant tank wasn't holding pressure; the indy across the street loaned me a used cap until my new one from Pelican arrived.
Congrats on the beautiful new ride! Sorry to hear about the issues driving home.
My '99 emptied its coolant recently...it ended up being a $5 parts...a broken plastic coolant fitting...

So I just spoke with the Alex, the mechanic at Harper and he has good news! Apparently, while the 160 deg thermostat was installed by the previous owner, the coolant had an air bubble in the system. When I got out of the car and it was idling, along with the recent side to side g forces I exerted on the car, caused the air bubble to escape out of the bleeder valve and then that in turn caused a syphoning of the coolant to follow.
In addition, the coolant was green which is a Porsche no, no, I am told.
Here is the red coolant going back in.
The pressure test came back perfect and the coolant reservoir is within specification. So I was able to spend a glorious morning in the mountains of TN and an afternoon in a tip-top waiting area. Unfortunately, the barista was self serve! But hey, at least they had espresso.
Hopefully this is the last time I will see her on a flat bed...with all the fluid staining the road, so embarrassing for her, I am certain.
I will be on the road in about an hour headed to Charlotte. I have to say, I am a bit gun-shy to go back to the dragon, just yet. I have a 4 - 5 hour drive ahead of me so will take the more direct route, which is a shame. I have had my share of drama and at this point, prefer the safe route.
I appreciate all the warm comments and the welcome I have received from the 996 community. In addition, thanks to Aristocrat Porsche in KC and Harper Porsche in Knoxville for their terrific service.
That's how it starts... soon you will be afraid of something breaking or scoring or cracking, and never drive it. Take the fun road... you only live once and can always fix it if it breaks!
Well, I am safely at home in Charlotte. I appreciate the encouragement but glad I took I-40 as it started down pouring just as I was leaving the dealership. I am even more impressed with the stable nature of the car. I couldn't "feel" the AWD but it was rock solid and if anyone has traveled on I-40 through Tennessee can attest, it is quite twisty and had a lot of elevation change for a highway.
Historically, I have gone to 4 track events a year and plan to keep up with that schedule. Anyone going to VIR in November, if so maybe we could meet up. I am signing off now and the journey is just beginning.

Well, sorry to hear you had to deal with the coolant issue. The 996's seem to remind all new owners that they are high maintenance machines. I test drove a 99 and it did a similar thing, turned out it was a crack coolant tank. Do the preventative maintenance and drive the heck out of her!
Btw, she's a beaut! Love the contrast of the black chip guards on yellow. I wonder how those would look on Lago green paint?
Good news it wasn't something serious. Flushing out the standard green stuff was a smart... we all want to live up to Porsche standards, right? Curious, what did the service cost you?
After the diagnosis, coolant flush and checking to see if the system was holding pressure, the cost was around $350, plus harper Porsche bought me a Grass-fed burger and hand cut fries!
I just had my Coolant system fixed as the "T" valve you can see to the right of the coolant tank and an elbow on the lower hose both had cracks in them and I was going through a tank of coolant every 1,000 miles... Car is back in my hands now.
*BTW you have a gorgeous car.... have fun with it.
FYI. I also have an 03 996 C4S. The generation car you have is a single row bearing. Does not matter that it was recently replaced !! Trust me Single row bearings have a 40% failure rate. A LN-Solution (NOT update) needs to be done for your car ASAP. I speak from experience of a motor grenading 4000 miles after a standard single row earring was replaced. Go to a licensed shop that can Install the LN Solution! It will run you 3k. Or be like mine and costsing15k to rebuild and now using the LN Solution. Your single town bearings has 40% failure rate. Does not matter how new or old the bearing s.
Thanks for the warning on the LN solution for the IMS issue. This car had the LN Solution installed in 2013, I believe as well as a new clutch at the same time. Sorry to hear about your experience, that must have been painful.
There is a significant difference between LN "upgrade" and LN Solution. Does your IMS have a direct line oil feed from the side of the oil filter back to the IMS ? If it does, them you have the SOLUTION. Otherwise you only have a replaced single row bearing. Hope it is the actual Solution. If not, locate a shop that LN certifies to install the Solution. It's not even a bearing for The Solution. It's worth your investment to do
again, pure suggestion to do since you just recently aquired the 996. They are amazing and it's worth the investment to have it done is all

(Cue Rennlist host on mic)...
Welcome ladies and gentleman to the greatest show on the earth right here on Rennlist.
This is the place where all the action happens. Regardless if you prefer MB Motorsports over Flat 6 Innovations, we have a place for YOU... AND all of your wild, outlandish claims too. So let's get started, shall we?!
Here today we have a new Rennlist user. Everybody welcome Atrain13! YAY!!!!! (clap clap clap)
Ok, you have the floor Mr. Atrain! Now what's your claim AaaaaaTrain?
(Atrain walks on stage and grabs mic)
"Does not matter that it was recently replaced !! Trust me Single row bearings have a 40% failure rate."
and... I also like to say...
"Your single town bearings has 40% failure rate"
(Atrain gives the mic back to the host)
Umm, (rolls eyes)... Well, ummm thank you Atrain, but please enlighten us to the source of the new information you've shared with our guests tonight. We're all ears where the Atrain got the 40% figure! How is that Porsche 996 and a single town both have the same 40% failure rate? We all know that California is going to hell in a hand basket (crowd laughs), but how is it that a single town is also experiencing failure at the same rate as the C4S bearing? Wow!
(Hands mic to Atrain for response) ... (Crowd gets anxiously quiet)
He's taking a page out of Trump's play book...makes up his own fear mongering "facts".
His next post will be to double down on this claim.
Anyway, he misspoke...everyone knows it's 40% chance the bearing will remain intact and function fine....and 60% chance of failure.
