How To Prepare Your Commercial Vehicle For Summer: The Easy Checklist

Summer’s heat is coming fast. Big trucks, work vans, and all commercial vehicles need your help to stay safe. You want your truck to work every day. You do not want a breakdown on a hot road. I can help you get ready. CLW GROUP is here for you. We build strong trucks and offer top after-sales and technical services. Read this guide — keep your business rolling, cool and safe all summer.

Why You Must Get Your Truck Ready

Hot weather can make trucks break. The cooling system will work harder. Tires can blow out. Batteries get weak in the heat. If you miss a step, it might cost a lot to fix later. You lose time and money if things go wrong.

Look at these facts:

Problem	How Heat Hurts	What Happens Next	Fix It Early and Save
Engine Overheating	Fast coolant loss, strain	Breakdowns often in summer	Check coolant, hoses, fans
Tire Failures	Hot air raises pressure	More blowouts and flats	Test tire pressure, inspect
Weak Batteries	Heat speeds up wear	Difficult to start engine	Test and clean battery
Bad Brakes	Summer heat weakens brakes	Harder to stop, more danger	Inspect, change pads early
Driver Fatigue	Cab gets too hot	Tired drivers, slow reaction	Cool AC, rest and hydrate

Don’t let small things stop your big plans. Use my checklist. Keep money in your pocket and your fleet moving.

Important Things To Check and Fix

Let’s use a simple checklist to keep every commercial vehicle — your truck, van, box truck, tipper truck, or semi-trailer tractor — ready for the hottest days.

Cooling System

Check coolant. Is it full and clean? Flush if dirty.
Look at radiator, hoses, and belts. No cracks or leaks.
Test the fan and thermostat. Fans must spin well.
Check radiator cap. It needs a tight fit.

Tires and Wheels

Test tire pressure cold. Tires gain pressure in the heat.
Look for tread wear and damage (bulges, cuts).
Check valve stems, caps, and spare tire.
Wheel bearings need to be tight and smooth.

Engine and Fluids

Check oil, transmission, and power steering fluids. Top up if needed. Use thicker oil in summer for heavy duty.
Inspect differential fluid.
Look at brake fluid. Top up and change if dirty.
Washer fluid for the windshield should be full.

Brakes

Look at pads and rotors. Are they worn out?
Check brake lines for leaks or rub spots.
Test parking brake.
Flush brake fluid if it looks dirty.

Battery & Electrical System

Test your battery. Heat drains batteries fast.
Clean terminals and connectors.
Inspect alternator and starter.
Check all truck lights and wiring.

Air Conditioning (AC) and HVAC

Turn on the AC. Does it blow cold?
Check refrigerant. Let a pro fill it.
Look at the cabin air filter. Change it if it’s dirty.
Does air flow from the vents fast?

Wipers and Windows

Change old wiper blades. Summer rain can hit hard.
Fill the washer system. Clean windshields mean safe driving.

Emergency Kit

Pack first aid gear
Bring water, snacks, reflectors
Add tools and cables
Hot weather? Pack extra water and salt or electrolytes

Steering and Suspension

Look under the truck. No broken springs, shocks, or loose steering parts.
Grease suspension joints if needed.

Fuel System

Check fuel lines for cracks.
Replace dirty fuel filters

I use these steps at CLW GROUP when we prep every delivery truck or van.

Don’t Forget The Driver

Your drivers are part of the team. The cab can get very hot. Heat makes drivers tired. You must keep drivers safe so they do not get sick.

Always have water ready
Rest often
Plan routes away from traffic jams
Make sure every driver knows how to check for signs of tiredness

A safe driver is as important as a strong vehicle.

Remember Your Cargo

If you carry food or cold goods, the reefer unit must work. Always check:

Cargo temperature
Refrigeration system
Secure every box and package
