Aircooled 911 Servicing and repairsWritten by Webmaster
Your air cooled 911 3.2 Carrera, 964 or 993 is in the best of hands at JMG Porsche, where even with servicing we go beyond the factory schedule.
Porsche 3.2 Carrera, 964 and 993 Servicing.
Service interval - We strongly advise that all Porsche cars are serviced every year, with a major service every two years.
The service schedule can be confusing with some service items needing to be performed every X amount of years, with other items being specified every Y amount of miles.
At JMG Porsche we have built a database for each model car, where every two years of age for your car, has listed the major service it requires in that year, which combined with every year in between major services the car having an annual service.
This means that for your model of Porsche, we can provide you with a plain price list for servicing, no matter what year your car was made, which makes it easy to see what service items are due and what the total cost will be.
To get a copy of the current service guide and price list for your Porsche, just email us to have your copy emailed to you in PDF format.
Eventually we plan on making it possible to register to the website and be able to download the latest version of this price list - Watch this space!
Interesting service and repair information for the air cooled 911 models.
Engine failures - Not nearly as common as horror stories on the internet of top end rebuilds being required every 130,000 miles would have you believe, but there are still worthwhile ways of avoiding unexpected large engine rebuild costs. One of which is proper servicing by a real Porsche specialist, which may not need cost as much as you think. There are also some ways to avoid unexpected bills by following some of our other advice bellow.
Brake fluid - Did you realise this should be changed every two years? Not doing this can cause problems with expensive parts within your car, such as the ABS pump or any part of the brake hydraulics due to water contamination as the brake fluid actually sucks moisture out of the air (hydroscopic), so even if the car is not used, the brake fluid must be changed every two years!
Transmission services - Not clearly noted by Porsche for when the transmission should be serviced and this vital expensive part of your car should not be overlooked. Just like your engine, the transmission is filled with oil/transmission fluid, which over time degrades. Not only this, but not many realise that many Porsche transmissions also contain a filter, which becomes clogged over time and can starve your transmission of lubrication, causing expensive repairs. We recommend all Porsche transmissions are serviced every 4 years or 40,000 miles, whichever comes soonest.
Diagnosis - Long has gone where cars had limited electrical equipment and a wiring diagram could be found in a manual from Halfords. Now the Porsche models have multiple separate computer systems, which all talk via networks, and many sensors to feed those computers with information about the world around it all tied together with many hidden wiring looms of thousands of wires and connectors. This can mean that in the event of your Porsche suffering an electrical issue, it is important that a Porsche specialist auto electrician is available, as we have at JMG Porsche. It is also important to understand that sometimes, finding the fault will not be as simple as plugging in a computer.
Drive Belt - Many of you may have had cars where a drive belt, timing belt or cam belt needs to be changed at a regular interval. Your Porsche model has a belt or belts which should be changed every 4 years. Failure to do so can cause instant overheating, loss of alternator charging and damage to the engine very suddenly. We recommend you have this changed at least every 4 years.
Heavy clutch? - A heavy feeling clutch which is stiff to use is not normal on a Porsche and often a sign that the clutch has almost worn out. Ignoring this can cause further damage, such as to the flywheel and clutch fork.
Alarm system - At JMG Porsche we are experts of all Porsche security systems and have reverse engineered all the various control units. This not only means we can program new alarm control units and keys to your car (late models), just as the main dealer can, but in some cases we can repair your old alarm control unit and keys, or in some cases recover your old keys to be used on the new alarm control unit, which is a service unique to JMG. For all air cooled 911 models we can bypass the original alarm system and install more modern alarm systems in their place which are Thatchum (insurance standard) approved.
Alarm system causes - In most cases the cause of alarm control unit failure is water damage, we can perform modifications to your Porsche model to help mitigate the chances of this happening to your Porsche.
