Volvo Repair: 1994 Volvo 940, rex regina, volvo 940

Question
Hi Roger,

How can I tell if my car has a Rex Regina coil system? I was online tying to buy the parts so a friend of mine could give me a tune up and some of the parts description indicated they would not work on cars with that type of system.  

Answer
E, that is true.  If your car does not have a air mass meter then its a regina/rex system.  If you look at your coil wire and it goes into a big coil pack with 2 connectors, then thats a Regina Coil.  Tune up on that care is just spark plugs and maybe a distributor cap and rotor if yours is worn.  If the wires look bad, then replace that too.  Nothing much on tuneups on these cars.  Roger
