Stop guessing on the next repair
The video was for a different engine.
Close enough is not good enough when the connector, the bolt or the torque value is different on your car.
The forum thread died years ago.
Ten pages of guesses, no diagram, and the last post says “fixed it, thanks” without saying how.
Pro software wants a check every month.
Repair databases are sold by subscription. Stop paying and the manuals are gone.
Mechanic’s Library puts the procedure, the wiring diagram and the spec for the exact vehicle in front of you in one place.
One payment of $97. No monthly bill, no per-VIN fee, and it is yours for life.
Everything for the job in one login
Open the vehicle you are working on and every tool is right there: the manual, the VIN, the recalls, the known problems and a mechanic to ask.
Step-by-step repair procedures for your exact vehicle
Pick the make, year, model and engine. Removal and installation steps, specifications, fluid capacities, trouble codes, wiring diagrams and service bulletins are filed under that one vehicle, so you never read the wrong engine’s procedure.
Decode any VIN and pull every recall
Type the 17 characters and get the year, model, trim, engine and fuel, plus every recall campaign on file with what fails and what the fix is. Then open the matching manual in one tap.
- No more guessing which engine is under the hood
- Spot open recalls before the customer leaves
See what usually breaks before you start
For each model you get a report built from owner complaints filed with NHTSA, grouped by component. Know the weak spots of that truck before you even pop the hood.
- Complaints, crashes, fires and injuries on record
- The components that fail most, ranked
Ask the AI Mechanic, get a plan of attack
Describe the symptom in plain words, attach a photo of the part or a recording of the noise, and get the checks in the order worth running them, with the values that matter. Every chat is saved, so you can pick the job up tomorrow.
2015 Ford F-150 5.0L, rough idle when cold with a P0300. What should I check first?
A cold-start P0300 on the 5.0L usually comes from mixture or ignition before the engine reaches closed loop. Check in this order:
- Intake runner control. Compare commanded and actual position on the scan tool; look for P2005 or P2007.
- Coils and plugs. Carbon tracks, oil in the plug wells, worn electrodes. Gap is 0.049 to 0.053 in.
- Throttle body and cold vacuum leaks. Clean the plate and smoke-test the intake while fully cold.
Then read Mode $06 misfire counts to see whether one bank or both are affected.

Questions, answered
Is this a subscription?
No. You pay once, $97 for Lifetime or $124 for Complete, and keep access. Nothing renews and nothing is billed later.
What is the difference between Lifetime and Complete?
Only the heavy trucks. Lifetime ($97) covers cars and light trucks: the repair library, wiring, specs, VIN decoder, recalls, Known Failures, AI Mechanic, transmission library and offline copies. Complete ($124) has all of that plus the Heavy Truck & Diesel library with 1,009 manuals and documents for medium and heavy trucks, buses and diesel engines.
Which vehicles are covered?
Cars and light trucks sold in North America from 1960 to 2025, across 69 makes, European models included in their North American versions. Motorcycles and models sold only outside North America are not included. Use the coverage checker above, or send us the year, make and model and we will check before you buy.
What do I get for each vehicle?
Repair procedures, wiring diagrams, specifications, fluid capacities, trouble codes, service bulletins, testing and inspection, component locations and more, filed under the exact make, year, model and engine. Plus the VIN decoder, recalls, Known Failures and the AI Mechanic.
Do you cover semi trucks and diesels?
Yes, in the Complete plan. The Heavy Truck & Diesel library has 1,009 manuals and documents for 34 makes, including Mack, Peterbilt, Volvo, Kenworth, Freightliner and International: service manuals, wiring diagrams, fault code guides, specifications and body builder books, plus engine manuals such as Cummins ISX, Mack MP8 and International DT466. The Lifetime plan does not include it, but you can add it for $27 on the checkout page or later from your dashboard.
Does the Lifetime plan include semi trucks?
No. Lifetime covers cars and light trucks (pickups, SUVs and vans) sold in North America. Medium and heavy trucks, buses and big diesel engines are only in the Complete plan or the $27 add-on.
Is there a free trial?
There is something better: the 30-day money-back guarantee. Use it on real jobs, and if it does not fit, you get the whole amount back.
Is there an app? Does it work offline?
Yes. Mechanic’s Library installs as an app on iPhone, iPad, Android, Windows and Mac straight from the browser: sign in, tap “Install the app” and it goes on your home screen with its own icon and opens full screen. No app store and nothing extra to pay. The manuals need a connection; for a job with no signal, save the vehicle as a .zip first, up to 30 vehicles a day.
How do I get access after paying?
As soon as checkout clears, sign in with the email and password you created. We also send a welcome email with the link.
Can my whole shop share one login?
Each login is for one person. Every technician who uses it needs their own access.
How do I get a refund?
Within 30 days of purchase, use the refund form inside your account or email support@mechanicslibrary.com. You get the full amount back.
