Working on Your Car

Reference Material

If you're going to work on your own car, there is reference material available that will make your life much simpler. The 924, 944, and 928 Models 1977 - 1988 Parts and Technical Reference Catalog is a valuable tool for ordering parts. The part number for the catalog is PNA 000 147 A.

The 944 Factory Shop Manuals are very useful and very expensive. However, the price continues to come down. The six volume set is now available for around $225 US. If you have a turbo model, you'll also need the turbo supplement which costs around $50 US. While the shop manuals are very nice to have, there are many jobs which can still be done without them. The shop manuals are available in the United States because of the "Freedom of Information Act" passed by the U.S. Congress. However, the manuals are still unavailable in most countries outside the United States.

Haynes makes a manual for the 944 which is available at most major auto parts stores for under $15 US. The Haynes manual does not provide procedures for many jobs which they feel are beyond the capability of the home mechanic. However, the procedures they do provide have good detail and good pictures. The Haynes manual is written based on an early model (pre-85.5), so you will discover differences if you're working on a later model or turbocharged car.

Recommended Tools

There are a number of tools I have purchased to work on my 944. In addition to a complete set (or two) of metric sockets and combination wrenches, there are a number of "special" tools which you'll need to work on your 944. Below is a list of some of those tools, what they are used for, and where they can be obtained. Refer to the Tool Source list for addresses and phone numbers of tool suppliers.
