Volvo Maintenance FAQ for 7xx/9xx/90 Cars                    Editor: Stephen 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, Swedishbricks and daily mailing list comments, from the RPR chatboard or from 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 16 Jun 00 and was compiled by Steve Ringlee, who is NOT a consulting mechanic but only recording secretary.

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, first visit the Brickboard Rear-Wheel Drive Forum and post a message.  You can reach this at  Another good source of basic help is the Swedishbricks mailing list, found at .  This is a closed list and requires that you join in order to participate.   You will receive good, unbiased advice very quickly at both of these forums.  If you have a 200-series car, there is an excellent FAQ by Bob Scheer, now maintained at
