The cold weather brings with it snow and worse SALT. Check the body work on your car for stone chipping and rust damage. The longer you let rust stay, the more complicated and costly it becomes to fix.

Hello Dave
Most companies have the opinion that tires should be replaced after approximately six years. Correct? My question being, I have a 1998 New Beetle I put snow tires on every fall. Therefore my original summer tires, are only on for about six months of the year. I hate to throw them out. My only concern, is wondering when they are going to give out.
John, Toronto

I don't think the tires would blow out as much as they loose grip The six year recommendation on tire replacement is for units that are out in the weather all year long. Usually after six years in the field the tires are worn out anyway...Based on your using the tires only 6 months of the year I don't think you should have a problem squeezing another season out of them. After that I would replace them. Better still take them to a reputable dealer and get their opinion.

Hey Dave
I have a 1992 Dodge Spirit. In reasonably good condition with 186,000 kms. I have had several instances requiring the changing of the Oxygen Sensor. The gentlemen who have been responsible for servicing the vehicle are at a loss to account for the repeated necessity to change the sensor. Can you help?

I personally don't think the oxygen sensor is defective...Oxygen sensor codes can be generated for several reasons. Lean operation conditions are the primary cause of a low Oxygen reading. Look for a plugged fuel filter, plugged EGR system, defective throttle body, or a simple vacuum leak. Anti-freeze leaking into the combustion process can also damage the sensor...In short have the techs spend more quality time with your car.
