What sets the price of a car repair, and how to get a clear quote first

Ask what an alternator costs and the honest answer is that it depends on the car. On one engine the alternator sits right on top, a few bolts and a belt. On another it is tucked down low behind other parts, and things have to come off before you can even see it. Same part name, very different job.

So this page doesn't list prices. It walks through what moves the price up or down, so a quote makes sense when you get one. Josh gives you the real figure for your car.

Parts vary more than people expect. Two cars of the same model and year can take different parts depending on the engine, the trim level or when the car was built. Some parts are common and easy to get. Others are made for fewer cars and cost more or take longer to arrive.

And a lot of repairs are really several parts together. A brake job is pads, and often rotors. A timing belt job usually means the tensioner and idler pulleys too. A radiator job can mean new hoses and fresh coolant. A clear quote lists what is going in, so you aren't surprised later.

Labor is the time the job takes on your car, and the biggest swing comes from access. A starter can be a quick swap from underneath on one car and a much bigger job on another, where the intake or an axle sits in the way. A serpentine belt on a four-cylinder may be right up front. In a crowded engine bay it can mean working by feel behind a tensioner you can barely see.

Timing parts are the clearest example. A timing belt on one engine sits behind a couple of plastic covers. A timing chain on another lives inside the engine behind a sealed cover, and getting to it means a lot more coming apart. The same goes for camshafts and some gaskets. The deeper the part sits, the more the labor.

Kansas City winters put salt on the roads, and salt works its way into the bolts under a car. A bolt that should spin right out can be rusted solid, round off or snap. Then it has to be heated, drilled or extracted before the real repair can go on. Brake jobs feel this the most.

An older car that has been through a lot of winters often takes more time on the same job than a newer one. Nobody can see that from a phone call, so ask how a quote handles it if a bolt fights back.

Once a wheel or a cover comes off, other worn parts are easy to see. Pads worn to the metal may have taken the rotors with them. A leaking gasket may have soaked the serpentine belt in oil. The radiator hose next to the one that split may be just as soft. Doing those now can save paying for the same labor twice later, but it is your call.

Josh tells you what he found and quotes it, and you decide what gets done now and what waits.

Some problems are obvious, like a split hose spraying coolant. Others take real time to track down. A no-start that comes and goes, a noise that only shows up on cold mornings, or a check engine code that could come from several places takes testing, not guessing. That engine diagnostic time is part of what a repair costs, and it is what keeps you from paying for parts you didn't need.

You can help. Tell Josh exactly what the car does, when it happens and what it sounds like. A short video of the noise or a photo of the dash lights helps a lot.

"Clear quotes" is how Josh puts it himself. You tell him what the car is doing, and he tells you what he thinks it is, what the repair takes and what it costs, before he picks up a wrench. Then you decide. When you get a quote from anyone, these are fair things to ask.

• What is wrong, in plain words
• What parts are going in
• What the total comes to
• What happens if something else turns up partway through
• What can wait, and what shouldn't
