spender replied to spender's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Greetings - I went ahead and did this on the weekend. Was not really a bad job, just lots to pay attention to! Took about 4 hours to get everything done (replaced one whole fan unit, and replaced the ballast resistor on one side) -- and this included cleaning out the rads. As it turns out, to be able to pull the radiator fans out on a C4S / 996 Turbo, you do need to remove the bumper as one of the bolts is hidden far beneath the bumper (the other 3 are easily accessible just by removing the wheel well cover). Once these are off, easy to pull out the fan mounts and either replace the whole fan unit (as I did on one side), and a little more work to replace the ballast resistors. What makes the ballast resistor a little more work to replace is that there is literally zero-tolerance on the amount of wire available (i.e you get one cut, that's it) and on one of the solder points, you need to splice two wires together and yet still join them to a fairly small mounting point. Anyway, I will post some pictures shortly.
spender replied to spender's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks Mac and Dave - appreciate the replies. However, the "resistor structure" on the 996 C4S fan is pretty different from the C2 996 resistor - part looks completely different and is stuck to the back of the fan assembly, rather than hanging down like a cigar. Anyway, I'm pretty sure it is still doable without removing the rads, might try next weekend.
Firstly, apologies for the cross-post. I put this topic up at Rennlist this morning, but got no replies... I need to change a ballast resistor on my C4S, and on this car, it's not as easy as for the slim-body 996s. I'd rather not remove the rads because it seems to me that would add a lot of work. Once I get the fan out, it'll be easy for me to change the ballast resistor (I'm an electronics guy). Based on instructions that I've seen in the Bentley workshop manual (pages 19-22 and 19-23), it looks like the whole fan housing assembly just slides off the back of the radiators (with the wheel liner removed) without too much fuss - apparently without the need for removing the radiator. Basically, I believe the order (adapted from Bentley) is to: 1. Remove rad mounting "circlips". 2. Remove bracket mounting bolts and bracket. 3. Remove radiator support bracket. 4. Disconnect fan electrical connection and detach remaining clips from fan housing. 5. Slide fan housing out of bracket. Is it really this simple? Am I correct then that you don't need to remove the full radiator to get the fan off? I've studied a picture of the 996 Turbo/C4S radiator, and it looks like if I undo the two screws noted (near the edge of the car) and then pull out, the fan housing should slide right out - it is only slide clips that hold the fan housing to the back of the rad. This correct? Also, how do you remove the "circlip" that the outer edge of the radiator is fastened to?
spender replied to Uwon's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)So is that part number (996-106-011-56) also the part number for the water pump for a 2003 C4S? Appears to be.
Does it sound anything like this (video clip): https://vimeo.com/51775214 I've got this problem right now.
spender replied to baker_g's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Not true - there are at least a few Porsche VIN decoders on the net, and you will be able to discover the original engine serial number in this way. Try http://www.autoatlanta.com/life/vin/vin.php (for basic information) or emailing to Suncoast Parts through their contact form. When I was looking for a P-car last summer, I would email Shawn the VIN and he would get back to me with some kind of computer factory printout.
spender replied to Oscarvan's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Any updates on this? How did it go?
spender replied to Dranon's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Gosh, I hate to reply to a thread this old, but I am having this problem. My washer fluid tank developed a leak a few weeks ago; car had to go to the mechanic for other reasons, so I got it fixed there. This morning, I notice that the same washer leak has developed again. After reading up on a few threads, I took my back fender liner off to see if I could fix this. I found a hose that fit into a groove in the tank and followed it to a "t" valve. Made sure it was jammed in good and tight. Sealed it all up, and it is still leaking... I'm not sure if I fixed the right tube. Can anyone describe what the tube and connection look like?
Try using BMW part number 26111225624-OEM-ID-E2E2217 / 26-11-1-225-624 / 26111225624 (depending on how you transcribe it). The part is slightly thicker, but is otherwise a good fit. I ran into this exact issue, and my mechanic ordered and installed this (after I told him that I had seen it as a "fix" on a number of boards) and it's been working great.
Given the number of views without replies, I figure I should add a little detail to my original post. Basically, I have a 2003 Carrera 4S that has a Tiptronic transmission. As a result of a small leak coming out of a set of seals (that I and my mechanic are carefully monitoring), the spectre has been raised that I may need to replace my transmission at some point in the future. I currently have an A96/35 Tiptronic S transmission (manufactured by Mercedes for Porsche), which was in the 2002 to 2005 Carrera 4 and 4S models. The 2000 to 2005 Turbo Tiptronic models had the A96/50 transmission, which is the same on paper (as far as I can see in Adrian Streather's book), except the final drive ratio is 2.89:1. Of course, these are both AWD models. Further to the above, I have started hunting around for another transmission, and at an early stage I have noticed that there seem to be a lot more Tiptronics from Turbos (the A96/50) that are available on the market. Thus, my question is if anyone knows if my 2003 Carrera 4S, which originally carried an A96/35, would be compatible with an A96/50, designed for the Turbos. Loren or anyone, please enlighten me. Thanks!
Is it possible to put a Turbo Tiptronic transmission (model A9650) into a C4S (which normally has model A9635)? These are both Mercedes Benz 722.6 transmissions.
spender replied to TimAustinW's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I love the custom emblem, do you remember the name of the eBay vendor? Nice and subtle custom upgrade, I like it.
spender replied to JeTexas's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Putting a 997 kit on a 996 just really sounds kind of "poser" to do. You'll only impress those who don't know anything about Porsches, and really, who cares what they think? :D
spender replied to ehljags's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I just bought one of these, and it looks like an extremely well-made item. For something that is made in the USA, I can actually understand the high price. Personally, I bought it to make the "oddments compartment" actually useful; it is so small I have a hard time getting my iPhone in there with a pack of gum! Also, an armrest for me is a big deal as I have rotator cuff injuries in my shoulders (I was a very aggressive skier in my 20s). I got the model with the cupholder as well, just because I figured, "why not?" I should mention that I spoke to Sam on the phone, and he struck me as a very honest, forthright, and straightforward guy to deal with. For all of you that are wondering why these things cost so much, just remember that "American Made" might cost more, but it is usually better made, and keeps your hard-earned cash within your own country. So, I support Sam Bird wholeheartedly! I'm going to install it this afternoon, most likely, so will let you know how it goes, and will also post some pictures.
Given the number of components that need to be changed, this seems like a massive job. If it were me, I would just sell your Tip car and buy another manual car - lots of good deals on 996s out there (especially 1st gen).
