Oil changes

When: Usually required every 5,000 miles

Cost: $112 to $121, including labor and parts

Why: Important to remove excess dirt that can build up in your engine from use

DIY?: Maybe—if you have the right tools

Tire replacement

When: NHTSA recommends that tires be replaced every six years, regardless of the number of miles driven

Cost: $100 to $300 per tire, not including installation costs

Why: Worn-out tires are not safe and can lead to your car hydroplaning in wet weather.

DIY?: No—it’s best to let a professional handle the tire replacement so they can ensure your new tires are balanced for even wear and a smooth ride.

Engine replacement

When: If the engine block is cracked, damaged in a collision, or simply worn out due to high-mileage

Cost: $6,500+

Why: A healthy engine will prolong the life of your car.

DIY?: No—

take your car to a reputable mechanic

for an engine replacement.

Windshield replacement

When: If the crack is longer than your hand, extends to the outer edge of the windshield, or is deep enough that it goes halfway into the windshield

Cost: $350 to $675

Why: A severely cracked windshield can impair your vision.

DIY?: No—avoid attempting to install a new windshield yourself.

Paint

When: Visible discoloration or paint peeling

Cost: $1,000 to $4,500

Why: A good paint job can prevent corrosion and improve resale value.

paint job

requires specific tools and knowledge, not to mention a safe place to apply the paint.

Sway bar

Cost: $104 to $144

Why: A good sway bar helps your suspension and improves your ability to corner safely

DIY?: No—this is a job for your mechanic

Thermostat

When: If you notice temperature gauge issues or if your engine is overheating

Cost: $236 to $268

Why: A nonfunctional thermostat could result in a cold engine, which will damage the vehicle

DIY?: Possibly. Be sure you have the skill and space to complete the

thermostat replacement

Water pump

When: If you hear whining noises or notice leaks

Cost: $217 to $357

Why: This part is essential for helping coolant circulate and preventing overheating

DIY?: No—you’ll need an expert for this repair

Manifold

When: Misfires and engine stalling are two telltale signs of a manifold problem

Cost: $493 to $672

Why: The manifold controls the air-fuel ratio, and a bad one could lead to engine problems

DIY?: No—take your Buick to an auto garage for manifold problems
