"If my car runs low on coolant, can I add water?"
Yes, if water is all you have available. However, water will contaminate and dilute the coolant, which has special protective qualities that plain water does not, and that your cooling system needs. Your car's cooling system should be flushed/serviced every 30,000 miles, or sooner, if you need to add water.
"The dealer told me I must have all my services done there in order to keep my warranty. It this really true?"
No!!
"My brakes have been making lots of grinding noises. What does this mean?"
Brake noise can be an indication of worn pads on shoes. However, some after market components used by those "economy repair shops" will make noise no matter what. Avoid this problem by having the best quality O.E.M. parts installed, like the kind used here at Dan's.
"What should I do when the 'check engine' light comes on?"
The illumination of this dashboard warning light (especially if it stays on) warrants investigation; but whether it should be treated as the sign of an urgent mechanical emergency depends on whether it coincides with a sudden change in your vehicle's drivability. If not, simply call us for an appointment at your soonest convenience and we'll test to determine whether the warning relates to an emission control failure or some other engine problem, or is simply a false alarm, calling for a resetting of the electronic "fault code". So the best answer is: don't panic, but don't wait too long to have us find out what caused you to "see the light".
