Is there any printed procedure on changing the rear 3 spark plugs that can be emailed or linked to? Or, can somebody explain the procedure if they have done it on an '04 RDV CXL. Could Buick have made it any more difficult to get to them?? Thanks Joe

Since your hand will be in the vicinity of the oxygen sensor, be careful not to damage the oxygen sensor wires. Next, twist the spark plug boot to loosen it before removal. I used spark plug boot pliers (OEM #25542) I picked up at AutoZone to remove the boots. Try to clean the spark plug recess area as best you can with compressed air before removing the plug. Then, use a flex-head ratchet with a long handle to remove the old plug. I used a Craftsman #42794 fine-tooth ratchet with a 5/8" spark plug socket on a 3-inch extension. When installing the new plug, hand tighten the plug with the socket and extension first before tightening 1/16" turn with the ratchet. Be careful when tightening the plug since the cylinder heads are aluminum. The service manual says to tighten the plugs 15 N-m (11 ft-lb), but good luck getting a torque wrench in there. Note that the service manual has you take the top engine struts off and rotate the engine forward to access the rear plugs. I tried this, but still could not access the rear plugs from the top. |

Our car is at dealer and mechanic can't understand what is causing our mirrors to move while the car's motor is turned off. First the passenger mirror began acting up, moving back and forth and making a noise until someone noticed it and came into a restaurant to tell us about it and then three weeks later the driver side mirror did the same thing. We are concerned that we may park it at night and have a dead battery the next morning. When we started the car both times the mirror "settled down". Also, from time to time the gas gauge goes a little crazy but eventually quits and is okay. The mechanic says if we can find any info on the mirrors it would help as they have never had the problem before with the rendezvousand of course, they can't get the mirrors to do anything. Any suggestions? They will have the car until Fri. evening.

| When I try to start the car, it makes a strange noise and the gauges and messages flash and click on and off. Sometimes the car starts, and sometimes it acts like a bad battery. I replaced the battery and it still does it. The clock on the radio occasionally resets to 12:00 after turning the key back on. A few days ago, it stalled in traffic with the overheating message coming on. The temp gauge went way up to hot then back down to normal within seconds. Any ideas or similarities? It's a 2003. Also have ABS and AWD lights on when I hit bumps. | |

Replying to: hammering (Nov 20, 2007 6:54 am) Oh, and for the overheating trouble the fact that it did stall would make me think it was really hot (not false indicaters), perhaps the thermostat got stuck closed for a bit. |
