Five Summer Truck Maintenance Tips

Five Summer Truck Maintenance Tips

Summer is approaching and for many of us, that means that the roads are getting busier and the sun is getting hotter. While it is important to prepare your truck for the winter weather conditions, it’s just as important to prepare your truck for the summer weather. Below are five summer truck maintenance tips to help you prepare.


1) Check Your Tire Pressure

Under-inflated or over-inflated tires not only can literally explode if they get too hot, but they also don’t perform well. In today’s environment, every mile per gallon matters and properly inflated tires help you and your fleet optimize your MPG.


2) Maintain Your Batteries

Typically, summer heat kills batteries 33% faster than winter cold causing more batteries to fail in the heat of July than in the cold of January. Heat speeds up the natural chemical processes that take place in lead acid batteries which will cause the battery’s electrolytes to evaporate. This increases the likelihood and severity of sulfation, which creates corrosion on the battery’s plates and robs a battery of its energy capacity.  Maintaining your batteries and your preventative maintenance checks are just as important in the summer as the winter.


3) Check Your Air Conditioner

Sitting in a sweltering truck isn’t much fun. This time of year is a great time to check your air conditioner for leaks in your valves and hoses. Any small changes now help keep your drivers comfortable, cool and happy as they drive this summer.


4) Replace Engine Belts

After this rough winter for the Northeast United States and Canada, our engines took a beating. Engine belts are often overlooked, but a simple check/replacement of these belts can save headaches and tow trucks in the coming months. Be sure to inspect your belts for cracks and other wear and tear to take preventative measures as we enter the summer months.


5) Check the Electrical System

With the complexity of these newer trucks, checking the electrical systems are becoming more important and more prevalent with fleets. Winter road chemicals can sometimes cause corrosion. Be sure to check the engine’s electronic control wiring and your battery cables and wiring to be sure they are not corroded or frayed and the connections are strong and protected.


These 5 summer truck maintenance tips can help prevent any breakdowns or dead batteries this summer. The more your trucks run, the more money you have the potential to make. Keep your equipment working for you and not you working on your equipment.


Thanks to and for the help with the information in this article.


  1. I thought it was great that you mentioned the toll rough winters can have on engines. My dad had to replace his engine belts after winter because the ice had somehow formed cracks in it. I think this is great knowledge to have to prevent future break downs.

    I like how you point out that the summer is a great time to check your air conditioner for leaks in the valves and hoses. My husband recently bought a truck, and he wants to make sure that he takes really good care of it so that it will keep running for a really long time. I wonder what other methods there are for keeping a truck nice and new.

    Vehicle needs special attention during the summer months to keep the vehicle in working order. Lack of adequate amount of coolant affects the performance of the cooling system in a very adverse way which could bring the vehicle to a halt in the middle of nowhere. So, the condition of different types of fluids including the coolant should be inspected regularly and any sign which indicates that the cooling system has some sort of mechanical abnormalities should not be ignored. Mechanical abnormalities associated with different components of the vehicle should be identified and repaired in time to keep the vehicle in working order.

    I liked that you mentioned preventive maintenance for your heavy truck helps avoid unplanned stops and improve his efficiency. My father and my brother bought a heavy truck for his company, and we are looking for advice to give maintenance to it. I will let him know about the benefits of regular maintenance to keep his heavy truck working properly.
