I used a crow foot and extension, a universal and another extension to get the third bolt off.

I read where someone used an endoscope to find bolt #3.

Pity our society doesn't let it run wild, and improve the species.
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.

I have a year 2000 C2 996 and my buddy is walking me through replacing my AOS and variocam wear pads at his shop right now and we noticed my car has the fuel cooler which as far as I know wasn't standard on the m96. I haven't had the car long so could the engine of possibly been replaced at some point? Anyone have any ideas?
There was a guy that lived up north and during one of the worst snow storms, goes outside to start his car to get to work, but without any success he goes back inside to think of a solution. He figures it was because it was so cold. He then quickly proceeds to "warm up his gasoline" on the stove.
He burns his house down.
That was unfortunately a true story.

My '99 C4 does have a fuel cooler.
The Essential Companion lists which years/models have the fuel cooler. If you want/need details, I can look it up tonight, but the short answer is that at least some US-spec M96-powered cars were equipped with the fuel cooler.
One of my "dumpling makers" parked her car outside because her garage had some construction materials in it during this winter...in Phoenix. On one particularly cold morning she could not make it to work because her windows were iced over and she did not know what to do. Her solution was to sit in the car with heater ON, waiting for side, back, and front windows to melt. She sat in the car for two hours waiting for the side windows to "thaw".
{{Coughs}} Do what??? Waiting for the windows to melt? huh???
For two hours?
Was the engine on or was she too thick headed to turn the engine on? Well, if it was started, thankfully she didn't do it in an enclosed area. Breathing carbon monoxide sucks!
hahaha
Thanks for taking my question serious apparently it's "cool guy" hour on the forum based on some other comments lol... Started taking things apart and was just curious why mine had it because it doesn't seem to be too common. Thanks
The '99 with it's double row IMS, cable actuated throttle, cable trunk/frunk release, optional LSD, and now a FUEL COOLER! Now if they just added in a cup holder and glove box standard, that would be the hot one to get for sure.
If your '99 was a US-spec C4, it had the fuel cooler - but it doesn't look nearly as tragic when installed properly - it's not prominent at all. I only noticed mine when I was sitting there staring at the engine wondering why the hell fuel lines and refrigerant lines were occupying the same space...Looking at the design, I bet I could have added one of those to a water pipe during my misspent youf with fantastic results. Ice-cold bong hits...hmm...
Unfortunately, the '99 C4 is e-gas like the later-year 996's. The C2 had the mechanical throttle linkage, but the C4 made the jump to e-gas early.
Not all C4's have AWD. Muhahahaha.
Someday I'm going to put a kart together with the FWD differential currently hanging in my garage...would be a really fun Saturday project. Maybe a gas-powered Big Wheel-type thing...
My 2000 C4 has the fuel cooler, so do Turbos. It is attached to the AC compressor. I have talked to lots of mechanics that did not know that some cars had these. Not many did. It uses a standard AC compressor and attaches on the compressor where the coolant lines attach.
So now you don't have to worry about your engine having to deal with hot fuel:-)
Definitely makes me happy knowing I may be less at risk for the cracked head issue... Always enjoy your insight on other posts I've seen thanks for your the info.
Ok that explains the confusion thanks! So I have to ask... Why would they do this for one year but then remove it for the following years because it seems to be effective since all the turbos have it... Also any known benefits?
Well looks like Porsche did know what they were doing when they designed this system, it's just sad that they dropped the concept because of cost. I'm pretty sure us Porsche owners wouldn't have minded paying an extra couple hundred dollars for an added upgrade.
It's been proven cooling fuel temperatures does add power, it allows for more/dense fuel to enter into the combustion chamber which means more power. why do you think turbo chargers have intercoolers the cooler air allows more air density which equals more horsepower. The Ferrari Lemans guys have been using it in their air conditioner system to drop the fuel temperature, they say it takes about 7-10 hp to spin the A/C compressor but they gain 30-40hp with it.
It's truly shameful to see total strangers deface your personal website, without clearing their comments with you beforehand.
Here's a thought: Calm down. Switch to decaf. It's a public commentary website.
Someone who just joined a month ago is not really in a position to dictate how a site, nor a string evolves.
Would you reply like that to someone at your local Porsche Club meeting? If you would, then you're probably a ****.
Alternatively, if you only save this for the online forums where you can post anonymously then you're also probably a ****.
Seems like the answer is the same in any event.
I hate to state the obvious but by posting about keeping the thread on topic you have actually added to the off topic posts. Ignoring/not responding to off topic posts is how you help keep a thread on topic.
Yes, I'm every bit as blunt when the need arises...but I never tell people what they may, or may not discuss on a public website.
Nor would I insist upon staying 'on topic' at a Porsche Club meeting, if we had one.
No; only a true a**hat would do that.
To Da NOOBS: welcome to the 996 NA forum. Wise cracks, smart azz comments, cajoling, etc. is the "norm" here but HELP/ADVISE is freely given to those who genuinely need it and ask nicely.
Yes that is what I have been told... My next question now is if the recirculation cabin air setting is on is it still cooling the fuel or does the air need to be coming in from the outside. Not trying to make rocket science out of this but just want to make sure I am benefiting most from having this feature lol.
Macster answered that same question when I asked it - if the AC icon is not illuminated on the HVAC panel, the fuel cooler is not being cooled.
As for the recirculate/max setting - that should not affect the fuel cooler. As long as the refrigerant is being chilled, the fuel cooler will be dumping heat from the fuel into the AC system.
Ok thanks. Very good to know. Lastly I guess the only way to know as well if it is working properly is to manually test the temperature of the fuel right?
I suppose the easiest way to tell would be to handle it - if it's cold, it's working. Or, if you are reluctant to freeze and/or burn yourself, an IR thermometer would also work.
When I pulled my engine last month, I was surprised to find I had the fuel cooler. 2001 C2. Engine number is from 2000 though. IMSB happened to be dual row as well.
I wonder if the AC unit on the cars with a fuel cooler,, have a connection to the rear deck fan,,
so if the engine bay got hot, the AC would come on? Sounds like not many have payed a lot
of attention to it,, and it would be like 1 wire..
I too have one that came with my used motor that was a factory (3.6) replacement.
But, my rollers AC was never discharged so I used that... I wonder if I should swap them?
The other advantage to that cooler is it should help keep the Injectors cooler,
I could see it being a decent advantage.. solenoids get slower with heat and fail faster..
I dropped my engine this past weekend. Had a devil of a time finding the third A/C compressor bolt. Then, according to the Pelican tech article (and Wayne's book) the compressor can just be pulled out and away from the engine. Well... if it doesn't have the fuel cooler lines, you can....
That third bolt and the fuel cooler lines probably took up 3 hours of my engine drop. Could easily see dropping an engine in under 5 hours the second time around (*knocking on wood).
I'm keeping on eye on your build thread. Might start one of my own over the holidays. Case halves are shipping off to LN today.
It didn't take me quite that long - but it was definitely frustrating. Probably an extra hour. I read where someone used an endoscope to find bolt #3. I did the same thing. I also removed the engine compartment temperature sensor and grommet to gain a small amount of ratchet extension access.
Hope to see your thread. I'll probably be just behind you on LN service.
I used a crow foot and extension, a universal and another extension to get the third bolt off. A hard line made it impossible to get a socket on the head.
