    P1514 is an idle air control valve fault (open circuit), normally a break in the wiring, a bad IAC valve, or a DME fault. Using a multimeter, test across pins 1 and 3 of the valve, you should see 16-19 ohms, if you do not, the valve has to be replaced. If the resistance is correct, you need to start tracing and testing the wires back to the DME, specifically looking at the wire connected to pin 29, a voltmeter should see 0V between that pin and ground. If battery voltage is detected, you need to check that wire length for chaffing or damage.

    Depending upon how big (capacity) your air compressor is, it may take some time for the vacuum to develop due to the volume of air it has to remove. Ideally, you need about 90 PSIG of pressure to make the system operate correctly. The only other possibility is something is open in the cooling system; if you have a cooling system pressure tester, it might be a good idea to try pumping the system up to around 18 PSIG and see if it holds. When we use the Uview unit, it starts to pull vacuum pretty quickly once the compressed air is started.

    Four functions of the coolant warning light: 1. Engine coolant level too low — light flashes slowly (0.5 Hz) 2. Engine compartment temperature too high — light flashes slowly (0.5 Hz) (engine compartment blower might be faulty) 3. Engine coolant temperature too high — light is lit; pointer on the right 4. Temperature sensor at water outlet faulty — light flashes rapidly (1 Hz); pointer on the right Note The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously (1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash)

    Because it is both the most common, as well as the best vacuum fill system, I will use the Airlift system as an example: Here is a video of how to use it on a Boxster: Uview instruction video

    Merry Christmas! There is no reason or need to pinch any hoses while using the vacuum filling system, and the bleed valve should be left closed during the process. Simply mix the coolant with distilled water in a 5-gal bucket, drop the pickup tube to the bottom of the bucket, pull about 24-28 inches of vacuum on the system, then slowly open the valve to allow the coolant to be drawn in. One of the biggest advantages of the vacuum system, besides speed and completion of a fill without any air pockets, is its simplicity. About 4-5 min after opening the valve to let the coolant flow, you are done.

    Just for your information, I would NEVER use anything from Beck Arnley as they are well known for poor fitment issues. Others make these kits as well. Along with the filter kit and fluid, you are going to need a fluid pump designed for a Tip, and a non-contact pyrometer to fill and properly adjust the new fluid level.

    Sensor looks like this out of the tank: Getting at it is a nightmare as the tank has to come out, after the engine is lowered a bit. Because of how the tank sits, it is covered from below and impossible to get at. In this video, around 9:30, you can see the plug and how it is released (simple pinch connector). If you are even thinking about going through this process, I would recommend buying a new (factory ONLY) tank and sensor, as these tanks are known failure points, and you really don't want to do this twice: 996 coolant tank removal Good luck!

    It needs to be disconnected at the tank.
  9. JFP in PA
    When was the trans last serviced (fluid and filter)?
  10. JFP in PA
    Welcome to RennTech Yes, it has to come out.

    If the rack has never been changed out, a VIN search in Porsche parts system will reveal exactly what part number the car came with, as well as any updated components released to the market since the car was sold. VIN based parts searches are by far the best way to do what you are trying to do; and most dealerships will not sell you a part without getting the car's VIN first because they don't want to waste time ordering in or shipping the wrong stuff. It is simply the best way to get the correct part. In all the years I have run my shop, we have not had any problems going this route.

    Then the VIN should be good. The two cases I ran into involved a "grey market" car (one that was never approved to be sold in North America and therefore should have never been registered as it lacked appropriate emission and safety devices for this market) and one that was stolen (VIN actually came back to a Honda Accord). Call Sunset parts, ask them to run your VIN to find out which rack should be in the car; parts departments do this all the time. 😉
  13. JFP in PA
    As you live relatively near Sunset, give them a call and ask them to run the VIN for you 503-718-6060. I all the years I have been running VIN numbers to get parts listing, I have only had the system say that twice, and both time there were problems about the car. Let's make sure the VIN is legit first, then get the parts you need.
  14. JFP in PA
    You can try running a parts search on board sponsors Sunset Porsche's online parts site, starting by entering the car's VIN which will figure out which rack is in the car.
  15. JFP in PA
    Yes.

    Sounds like you may have a bad stat that is jammed open, which is better than jammed closed, which is probably what triggered your overheating event. Pull the stat and look at it, if it is open, that is your culprit.
  17. JFP in PA
    As yours is a five-chain engine, I would be willing to bet that the biggest part of the deviation values comes from worn chain pads located between the two cams on each head. This is a very common problem, but fortunately the fix is cheap parts wise, but does require some labor to get at them. I don't remember how many of these we swapped out over the years, but it was quite a few.
  18. JFP in PA
    Anytime, that is what we are here for. 😉

    Because the flywheel bolts are torque to yield, and are acutally stretched under load, thread locker is not required. The pressure plate bolts on the other hand are relatively low torque spec bolts, so they would benefit from an application of a medium strength thread locker like LocTite blue. In no case should either the flywheel or pressure plate bolts be reused, they must be replaced.

    How declutching alternator pulleys work
  22. JFP in PA
    Manual transmission cars used declutching alternator pulleys, while the Tip cars did not.
  23. JFP in PA
    Any quality aftermarket metal based, or marine grade anti seize compound will do the trick, Amazon sells them:

    Then your AOS is fine. We checked every car that passes thru the shop for this vacuum level, just as a precautionary measure as the cars tend to show higher vacuum levels for a bit before they become problematic and need to be changed.

    When contemplating a later model Porsche engine replacement on one of these cars, you need to take a lot of things into consideration, such as: The fuel systems changed year to year, some changes were minor, others not so much. Later engines are nearly totally CAN Bus technology, the early cars had none; over the years, there have been multiple DME changes, some were significant, and trying to use the later engines can turn into and electronic and reprograming nightmare. I could go on, but I think you get the picture. You need to understand just how much will need to be changed to make a possible swap work before you leap into a financial black hole......
