New update; after more than 800Km after replacing the cap with a new one I have not had any issue with the coolant, so I assume it was only a cap problem. Thanks Loren,for your advise, the cap is a common problem, and it was a 04 one!
Update: So I replaced the cap with a new one, been driving it around for 2 times for about 70 kms, have not had any more fluid loss, engine temps stays around 80 C with the fans kicking in just a tad over 80 C as always, I still keeping an eye on it every time and at the level when it completely cools down and everything seems normal, for now. I'll keep a close eye on it, but does it make sense to assume it was only a cap problem? Thanks in advance for any feedback on this issue. Have a great day! Fermin
Hello again, finally it was easier for me to get a new pressure tank cap, as I have not lost any more fluid I plan to drive it again with a new cap and keep it on check. If the problem do not repeat I tend to think that it was caused by a malfunction of the cap, does it make sense? does a "loose" cap could do that, maybe I didn't tighten it enough?(when I added coolant, I don't think so but, could it be?) Thanks again for your help!
Hello Loren, the cap number is 996.106-447.04 Could it be the problem? Should I replace it before driving it again? Thanks More details about my car: Boxster 1998, 2.5 manual, 100000kms bought about 5 yrs ago with 85000kms
Advise appreciated This morning as I was checking oil dipstick oil level I also added a little of Porsche engine coolant to my tank to get it to about 3-4 mm off the max level. I added some cause I wanted to keep it at this level, (have not added any since about 2 summers ago). Went out and drove for about 30 k, when got to destination I lost some coolant.... that's it I think the tank has cracked, so I bought some water to replace the fluid in order to get back home again. As is difficult to really see the level in plain sunlight, I added water, to my surprise just could add about 150-200ml max ? Put the cap back again and started the engine, it never got hot (all the time the needle was in the 80 C mark) so I decided to drive back home, didn't lost any more fluid and engine temp was OK all the time, even if it was a warm day (29-30C) At home took the plastic sheet beneath the oil and coolant caps, and noted that there was signs that coolant had gone by the overflow drain. Didn't lost any more fluid, but I extracted around 150 ml of coolant with a seringue to get it to the max level once the engine had somewhat cooled down. I replaced the cap some about 3 yrs ago, with the new one, I had the original and read somewhere that it could be a good idea to replace it, so I did. Should I replace it again? Could it be just the cap malfunctioning? I was planning to drive it again tomorrow around here to see if everything is normal (as it seems!). Thanks in advance for any advise, I reatly will appreciate it. Fermin Boxster 2.5 1998
Boxter 1998 2.5. Today used the key to open my door, left home and when I tried to lock it (with the key, remote doesn't work anymore) the lock was stiff and didn't want to release the key! I played with it, couldn't unlock the car, luckily roof was down, finally unlock the door from the inside, pulled out the key and headed back home. I put some oil on the lock (bad idea probably) tried to lock unlock, it locked and again key was stocked.played forced a bit and lock did a full turn,,,, released the key after playing a lot with it! Now I can't lock the car from the console, passenger door locks, trunk lever locks but not the driver's door... I think the lock is broken and it doesn't get electrical signal anymore. What can I do? Thanks in advance for any help on this! Found some tutorial's on Bentley and 100 project's book, anyone with some experience or advise? Thanks, Fermin' Laval, QC.
The Mobil filter is a pretty good filter. Our personal favorites are the Wix/Napa Gold 51042XP, which you can usually get for less money as well. I think Amazon carries them, as well as many auto parts outlets. If you go to this site (http://www.wixfilters.com/WhereToBuy.aspx?ZipCode=) and enter your postal code, they will give you info on who sells Wix in your area. Thank you JFP
Hello JFP, for my next oil change I've been looking to buy a spin oil filter adaptor for my Boxster 2.5L 1998 and locally I can have the Mobil M1-107 filter also recommended by LN, is that a good match? and if I understand it well, it will improve oil filtration, wich is good for the engine. I've allready replaced the oil plug with a magnetic one to inspect for debris. Thanks in advance for your (always very good!) advise. Fermin
Ahsai, thanks a lot!; also I read in other forums that it could be the seal (old and cracked) of the gas cap, mine was, so I changed it today and erased the code... will see... but if it comes back I'll know the next step, Thanks!
Hello, got the P0446 code today, I've been reading in the forums that I'll need to, as a first step, blow compressed air in to the purge line from the EVAP Cannister, I have some diagrams but how do I do that, from the cannister? and how do I know which is the purge air line? Any help with this will be greatly appreciated, thanks. Porsche Boxster 1998 2.5L engine, manual transmission.
Hello everybody ! Clutch on my Boxster 1998, 90000kms is giving signs of trouble, it "jumps" a bit on 1st or reverse at low RPM. As I bought my car at around 85K, don't know how it was driven, but probably will need a clutch replacement, and RMS at the same time, I live in a Montreal north suburb, does somebody can recommend a good independent Porsche garage around Montreal or Laval,, dealer is a bit overprice. Also, when clutch and transmission are removed, is it possible to verify IMS bearing ? Thanks in advance for any advise on this subject. Happy Boxster drive ! Fermin.
I just bought a Boxster 1998 about a year ago with 87000kms, it's a blast to drive, even if it's a 2.5 ! No issues for now, just the air bag lite.and it was a seatbelt issue. When I was young ( many years ago!) I had the oportinuty to drive several european sports cars, but never a Porsche, abd many years after, (and after raising a family) when I drove the Boxster, I fell in love with it ! Good luck!
The more I read the forums, the more I know about my car 98 Boxster 87500kms, but also some times the more I worry. I've been reading much about RMS and IMS failures, my car leaks an oil drop between engine and trany, sometimes more often than others, and it seem to me that the more I drive it the less the leakage, could it be? last Sunday, bluebird day, we drove around 300kms, highway and little hilly country roads, not a drop since! Dip stick oil level always right. I'm waiting until I'll have to change the clutch to do it all. Runs great, last srping when I bought it, I did some basic maintenance, changed the motor oil, trany oil, did a 86000kms service with the dealer, flush coolant and brake oil, but they didn't mention anything wrong with the fans. Car runs great but... for me a bit on the warm side, asked questions at the dealer, only to be told that I'm in the "normal temps"... on highway needle is at the bottom of the zero of the 80C temp (Canadian car), but as soon as I get into some light traffic or stop lights, temps tends to go up until the upper part of the 80C zero (I figure temp should be around 100C) and that is when I hear the cooling fans go on, but at a very high speed. Yesterday I did talk with a 2001 Bosxter owner, engine was running, asked for the temp and he told me it always stays around the bottom or middle part of the zero of the 80C, and heard a smooth running of his fans. This evening (is not my daily car) went for a drive, and noted that my cooling fans are probably not turning ON at low speed. Fuses seem right, seems to me a bit rare that the two relays would not be working, I love this car, I'm trying to avoid dealer (overprice and under-service), but I don't know any good independent mechanic around Laval, or Montreal, does anybody know? "Accrochez vous a vos rèves" as JFP in PA say, and any help in keeping this beautiful classical gems in good health would be really appreciated. Fermin
