I love my scion. It has been the best car I have ever had the pleasure of owning and I’ve had some clunkers! I had the belts replaced 2 years ago and they now squeal so loudly (only when it’s cold out) that dogs start howling! Do they need to be replaced again or is something else wrong? I know very little about cars. I can jump a battery, change the tires, look under the hood, shake my head with my hand on my hip all while scratching my head. And that’s the extent of it. Any other preventive maintenance suggestions- other than oil changes- that should be done so that I can drive this car to 300K miles?
