Volvo Maintenance FAQ for 7xx/9xx/90 Cars                                                     Editor: S. Ringlee

This list was developed for the owners of Volvo 7xx/9xx series cars who are interested in maintenance tips that are not generally available in commercial manuals. It was compiled from Brickboard and specific websites with useful information. Items which appeared to be of lasting value to 7xx/9xx/90 series owners were excerpted and copied to this file. Sincere thanks to all those who took the time to answer others' questions and contribute to this public discussion.  Because these remarks represent contributors' personal opinions, users need to exercise caution about any advice given; indeed, some of the comments are contradictory. This list is current as of the revision date below and was compiled by Steve Ringlee, who is NOT a consulting mechanic but only recording secretary.

Buying a Used Volvo 700/900? See Buying Used and Vehicle Preventive Maintenance for tips, trouble spots, and items to look for.

Note:  If you are having specific driveability problems (no start, poor idle, etc.) with your Volvo, start your search with the Engine Tune and Performance; Symptoms section where many common symptoms are described and diagnosed.  Other driveability problems are described in Electrical: Ignition System, Electrical: Engine Sensors, Etc, Engine: Fuel Injection and other areas.

If you need help or consulting advice, several Internet sources exist. Visit the Brickboard Rear-Wheel Drive Forum and post a message.  You can reach this at http://www.brickboard.com/RWD/.  If you are in the UK, the UK Volvo Owners Club at http://www.volvoclub.org.uk/ has a high quality series of forums arranged by Volvo model. A US distributor of Volvo parts, RPR in Berkeley, maintains a technical advice forum at their website: http://www.rprusa.com. Another good source of basic help is the Swedishbricks mailing list, found at http://www.swedishbricks.net/contents.html .  This is a closed list and requires that you join in order to participate.   You will receive good, unbiased advice very quickly at any of these forums.  If you have a 200-series car, there is an excellent FAQ by Bob Scheer, now maintained at http://www.swedishbricks.net/contents.html

Here is a short testimony from someone who benefited from Brickboard: "I would just like to thank the wonderful people on the Brickboard who helped me fix my car. I was about to sell the car because I couldn't fix it and couldn't afford to take it in to a shop. But the wonderful people who helped saved me by finding the problem and helping me fix it for $5. Thanks again! Charles." This is typical.
