20 Point Vehicle Inspection Checklist: By System

A 20 point vehicle inspection checklist is one shop's list, not a standard. This article gives a working 20, grouped by system, and then helps you decide whether your own sheet should be shorter or longer. It covers your shop's own record. A state inspection is a different job.

The 20 point vehicle inspection checklist at a glance

The 20 points fall into six systems. Tires get three points, brakes three, fluids, belts and filters six, battery, lights and wipers four, steering and suspension three, and the underbody one.

Each system has its own section below.

1. Tires: points 1 to 3

Point 1 is tread depth in 32nds of an inch at each wheel position. Washington's tire law treats a tire as unsafe below 2/32 of an inch in any two major tread grooves measured at three places around the tire, so set your own Attn point higher.

Point 2 is the tire pressure you found and the pressure you set.

Point 3 is the DOT date. Under federal rules for tire identification, the last four digits give the week and year the tire was made.

2. Brakes: points 4 to 6

Point 4 is pad or shoe thickness in millimeters at each wheel. Point 5 is rotor thickness against that vehicle's minimum, or drum diameter against its maximum. Point 6 is brake fluid level and condition.

Take rotor and drum limits from service information for the vehicle, since no one number fits every car.

3. Fluids, belts and filters: points 7 to 12

Point 7 is engine oil. Point 8 is coolant. Point 9 is transmission or CVT fluid. Point 10 is drive belts. Point 11 is coolant and heater hoses. Point 12 is the engine and cabin air filters.

For each fluid, record level and condition separately. A full reservoir of dirty fluid is a different finding from a low one.

4. Battery, lights and wipers: points 13 to 16

Point 13 is the battery: terminals, hold-down and a tested result. The Car Care Council says to test the battery every fall and to consider replacing one that is three years old or more.

Point 14 is headlamps on low and high. Point 15 is brake and turn lamps. Point 16 is wiper operation and washer fluid.

The same council advises checking a car's lights at every oil change.

5. Steering and suspension: points 17 to 19

Point 17 is tie rods and ball joints. Point 18 is shocks, struts and CV boots. Point 19 is wheel bearings.

6. The underbody: point 20

Point 20 is under the vehicle: exhaust, fluid leaks and where they are, brake hoses and the parking brake, and the frame and underbody. Write the location of any leak in the note.

How to choose between a short sheet and a long one

More points do not make a better inspection. A longer sheet records more, and a tech has to look at more. The right length is the one your crew fills in on every car.

A point count tells you how long a sheet is. It says nothing about how well it was filled in.

A multi-point inspection is the general name for a sheet that checks many items in one visit. A 20 point inspection is a multi-point inspection with twenty rows. No standard says what the extra points must be, so the two terms describe the same kind of sheet.

Whatever length you choose, settle three things. Mark every row with the same three marks, which are Pass for OK today, Attn for needs attention soon and Fail for needs repair now. Write the measurement behind every Attn or Fail. Set your own alert points for tread, brakes and battery, and keep them on the sheet.

Techs use a sheet the same way when the rules sit on the sheet itself. Both sides print the Pass, Attn and Fail legend, which repeats your alert points in that legend, and includes two filled sample pages that show how a finished sheet looks. We make no claim about training, so walk your crew through the sample once and see how it goes.

Which points matter most, and how long they take

If you can only keep a few rows, keep the ones a customer could get hurt by. Those are tires, brakes, steering and suspension, and the lights. Fluids, filters and wipers come next. Cabin comfort items come last. This is practical advice, not a rule, so reorder it for the cars you see.

No one can give you a fair time for a 20 point inspection. It depends on the vehicle, the lift, the tech and how many measurements you record. Time a few real cars with your own crew, write down the average, and plan the bay schedule around that.

Handing the result to the customer works best when you lead with the Fail rows, then the Attn rows, and read out the measurement behind each. Keep what you completed separate from what you recommend, so the customer can see which is which. A Findings and estimate sheet covers that, and you print it for jobs where work needs a handoff.

Where a 20 point sheet falls short

A 20 point list leaves out whole areas. It has no row for HVAC, the horn, reverse lamps or spark plugs. If you want those, you need a longer sheet. A shop inspection also does not replace a state inspection. New York's DMV describes a program run through inspection stations with its own sticker, which your shop sheet does not issue.

A printed list is also the wrong tool if you want photos with each finding or a link sent to the customer's phone. Inspection software does that.

A sheet built by system, not by count

The Multi-Point Inspection Kit is built by system rather than by a count. Its two-sided inspection sheet rates each with Pass, Attn or Fail and gives each a note field. A shop standards page holds your own alert points, which then repeat in the legend on both sides. It does not advertise a point count, so you decide how long your checklist is. The kit costs $4.00.

The Multi-Point Inspection Kit is your shop's own record. It is not a state inspection, not a manufacturer form and not a private buyer's checklist. The paid kits have shop fields for the name, address, phone and logo, plus an add-your-logo tool, so your sheet carries your shop. That tool was tested offline in Chromium. Chrome, Edge, Safari and Firefox were not run, and nothing is uploaded. The free sample has no logo tool.

You can type into the PDF on screen, then print it at Actual size (100%). We tested the fillable fields only in pdf.js, the viewer built into Firefox, running in Chromium. Other viewers are untested, so check yours before you rely on it.
