BLOG POST: 5 Essential Car Tools Every Driver Should Keep in Their Boot (Mechanic’s List)

By Gary, AutoAdvice Online — 29 Years Motor Mechanic

When your car lets you down, it never happens at a “good time.”
But here’s the reality most drivers don’t realise:

👉 80% of roadside issues can be solved in minutes… if you’ve got the right basic tools.

As a mechanic of nearly three decades, I can tell you right now — these are the exact tools I always keep in my own boot. And they’re the same tools I recommend to every driver, whether you're a first-time buyer or a lifelong petrolhead.

Let’s get into it.

1. Heavy-Duty Jumper Cables (3–5 Metre)

Dead batteries are the #1 cause of roadside callouts.
Cheap jump leads are a waste of time — thin cables melt, and short ones won’t reach.

Why you need them:
✔ Starts a dead car in minutes
✔ Long cables = easy reach
✔ Heavy copper = safer, reliable

2. OBD2 Fault Scanner

Modern cars store fault codes for almost everything.
A simple OBD2 scanner can tell you instantly whether a warning light is serious or minor.

Why you need it:
✔ Saves you money
✔ Prevents unnecessary garage visits
✔ Lets you reset minor faults

If you only buy ONE smart tool — buy this.

3. Emergency Multi-Tool Kit

A compact tool kit should cover essentials like:

• Pliers

• Screwdrivers

• Basic spanner

• Electrical tape

• Utility knife

Why you need it:
✔ Tighten loose battery terminals
✔ Remove undertrays
✔ Quick roadside fixes
✔ Fits in glovebox

4. Tyre Pressure & Inflator Kit

Under-inflated tyres cost fuel, cause blowouts, and kill handling.

Why you need it:
✔ Inflate tyres anywhere
✔ Avoid ruining alloys on a flat
✔ Essential for late-night or motorway emergencies

A pressure gauge + mini compressor grips all the basics.

5. Brake Caliper Wind-Back or Press Tool

If you ever plan to service your own brakes or just want protection in emergencies, a caliper press tool is a lifesaver.

Why you need it:
✔ Helps diagnose sticking brakes
✔ Makes pad replacements a DIY job
✔ Prevents uneven wear

Home mechanics especially — you need this.
