  1. Are you sure your fan is bad? There have been a number of reports here where folks found weather stripping or something else hitting the fan. Do a search here to find more...
  2. Electric fan, speed 1 Coolant temperature higher than 96.75° C or air conditioning switched on. Electric fan, speed 2 Coolant temperature > 102° C or air-conditioning fluid pressure switch closed (coolant pressure > 16 bar). The electric fans for the radiators are only triggered when the engine is running.
  3. Yes, unless there are spacers on the car.
  4. Most of that is in the model year specific Technical Service books. You always need the first model year of each book as they give detail of just about everything new to the car. After that the next years book just lists changes from the previous year. Too my knowledge they all turn off at the same RPM including VarioCamPlus. Porsche calls resonance/crossover "boost" - the Resonance Flap. I don't have detail on early the Boxster (perhaps Tool Pants has a MY97 Boxster Tech Book) but on 3.4 liter Carrera it works like this: "An intake system divided by a resonance flap allows utilization of oscillations along the intake air column across a broad speed range (resonance supercharging). Due to the different working cycles of the individual cylinders, air is drawn from both reservoirs in the intake system alternately. The mass air flow in the intake system is excited by the alternating induction. In the case of resonance, the intake frequency of a cylinder line matches the frequency of the compressive oscillations in the pertaining reservoir. This frequency is determined by the geometry of the intake pipe, the resonance pipe, and the reservoirs. However, the overall length of the pipes from the intake cylinder to the subsequent intake cylinder, the division within the intake and resonance pipes as well as the reservoir depth in the flow direction are the deciding factors. The DME control unit activates a diaphragm valve controlled by negative pressure. This valve opens or closes the resonance flap. The resonance flap is closed when de-energized, but is actuated and open whenever the ignition is switched on. If, after the starting process, the engine reaches the programmed idle speed, the resonance flap is closed again. Switching points of the resonance flap: Resonance flap not actuated between 700 rpm and 3,120 rpm and from 5,120 rpm. Resonance flap actuated between 3,120 and 5,120 rpm, if the throttle is open by more than 30%."
  5. When it rains... does the alternator get wet? Do other parts of the engine compartment get wet? I would certainly also check the 8 plug socket on the engine (current distribution) - since all the current distribution goes through there.
  6. :welcome: P1349 Camshaft Adjustment, Bank 1 – Below Limit Solenoid hydraulic valve is triggered, camshaft does not switch into early position. Possible fault cause: - Dirt in system - Solenoid hydraulic valve mechanically blocked
  7. :welcome: Take the distributor cap off and turn the engine until the rotor points at cylinder 1. If you are at TDC then the mark on the pulley will be at 12 o'clock, the next mark will be at 4 o'clock and the last mark will be at 8 o'clock.
  8. Loren, did you have a hard time getting the plate and the braces back on? I changed my transmission oil today (2003 Boxster S) and was surprised how hard it was to get the holes to line up with the studs, for both the plate and the braces. I was worried that I had pulled it out of alignment by using ramps instead of jack stands. But looking at your photos, you used ramps too. Wondering if you had any alignment problems after doing this? Thanks I didn't do these - member schreb did. As I recall it might take a little pushing to get them back in place.
  9. I think if the Variocam were not working right you would get poor torque in the mid-range. The MAF is critical for high RPM since it measures the air flow.
  10. VarioCam is deactivated at 5120 RPM. I think he has a bad MAF.
  11. If the only thing you get out of PCA is the magazine (Panorama) - it is well worth it (IMHO). Other benefits (depending on your needs) are: Discounts for parts and service (at dealer discretion) Driving schools Autocross Ralley The yearly Porsche Parade event Technical Sessions Club Racing Valuation committee to help you establish the value of your Porsche for insurance purposes. all events (even tech sessions) are covered by PCA's insurance and many more I am sure someone else can think of. I have been a member for 29 years and I never been able to do all the events but I have enjoyed many of the one's I have attended.
  12. Yes, they are the same for all four wheels. There is a different part number for MY03 and newer as well as C4S.
  13. "after-market spoiler" - I think you will need to talk to the spoiler manufacturer.
  14. How To Replace Rubber Bellows Under 996 Rear Spoiler
  15. You can certainly look at your oil but I would start by looking for cracked coil packs on cylinder 5 and 6. On MY99 they are old and brittle and can certainly crack - especially if they were ever overtightened.
  16. 74mm 14 flute - $3.99 at Pep Boys (3/8" drive)
  17. Start here... Adjusting Hood Latch Mechanism
  18. Yes, 5 watts. If you have clear side markers then you will need the orange bulb (in the US).
  19. My advice is to be very very careful. A new PIWIS from Porsche is $18,000. There have been many software updates - so check the version. There is one on eBay right now for $20,000 (the price is ridiculous because it is higher than US list). http://cgi.ebay.com/ebaymotors/Porsche-PIW...1QQcmdZViewItem
  20. That looks like it - does your car have the wiring in place?
  21. As of MY02 all 911 models are fitted with belt tensioners and belt-force tensioners. The pyrotechnic ball belt tensioner is combined with the belt-force limiter in one unit. Yes, disconnect the battery and remove the key from the ignition. Wait at least 5 minutes before proceeding. The electrical connection (fuse/trigger) to the seat belt reel will likely need a screwdriver to remove it. If the belt fires the tensioner then it will have to be replaced.
  22. Please keep your content to Porsche related items - thank you.
