Preserving Heavy Equipment From Summer Heat and Preserving Long-term Value

When temperatures rise, your heavy equipment feels it too. 

Whether you're preparing to sell your machinery or buy reliable equipment at auction, summer is a critical time to stay on top of maintenance. Proactive care not only improves performance but also preserves long-term value.

The Impact of Heat on Heavy Equipment

Extreme heat can put significant stress on construction and agricultural equipment, leading to premature wear and costly repairs. High heat can lead to overheating and affect engine efficiency, hydraulic performance, batteries, and even tire integrity. Operators may experience breakdowns, reduced productivity, and unexpected downtime. 

Keep Equipment Strong This Summer

Regular maintenance is one of the easiest ways to increase resale value and protect your equipment investment. Here are a few maintenance tips every heavy equipment owner—or future owner—should prioritize this summer:

Cooling System Maintenance

One of the most critical components in preventing heat-related issues is the cooling system. Follow these steps to keep it in optimal condition:

  1. Check coolant levels regularly – Ensure coolant is at the proper level and mixed correctly to prevent overheating.

  2. Inspect radiators and fans – Remove dirt, debris, and dust from radiators to maintain efficient airflow.

  3. Monitor hoses and belts – Heat can cause rubber components to crack or degrade, leading to coolant leaks.

Proper Lubrication

Summer heat accelerates oil breakdown and increases friction in moving parts. To prevent excessive wear:

  1. Use high-temperature lubricants – Some manufacturers offer summer-grade lubricants and oils suitable for higher temperatures. 

  2. Monitor oil levels – Check oil regularly and change it according to the manufacturer's recommendations.

  3. Inspect hydraulic fluids – Heat can cause hydraulic fluid to thin out, leading to inefficient operation. Keep levels topped off and use heat-resistant options if necessary.

Tire Care in Hot Weather

Excessive heat can increase air pressure inside tires, leading to a higher risk of blowouts. To prevent tire-related issues:

  1. Check tire pressure daily – Overinflated or underinflated tires are more susceptible to heat damage.

  2. Look for cracks and wear – Summer heat can accelerate tire wear, especially on rough terrain.

  3. Store equipment on solid surfaces – Keeping machinery on gravel or concrete rather than soft ground can help maintain tire integrity.

Battery and Electrical System Precautions

High temperatures can cause batteries to drain faster, leading to unexpected failures. Keep electrical components in top shape by:

  1. Testing battery voltage – Heat can shorten battery life, so regular voltage checks are crucial.

  2. Cleaning terminals – Dirt and corrosion buildup can lead to poor connections.

  3. Reducing electrical load – Limit unnecessary electrical usage, such as excessive air conditioning, to preserve battery life.

Proper Storage

Storing trucks and heavy machinery under cover or in a garage when not in use helps protect them from the elements, preventing sun damage and rust.

Summer Is Prime Time to Buy and Sell

Market trends vary, but the summer season is one of the best times for both buyers and sellers. 

If you're planning to sell equipment, know that many buyers are still actively upgrading or expanding their fleets for summer and fall workloads. Well-maintained equipment attracts more buyers and higher bids at auction. In addition to a full inspection, be sure to:

If you're in the market for new-to-you machinery, summer is also a great time to explore buying at auction. Sellers are often motivated to move equipment during the summer season, and many items have just come off spring work cycles, making it easier to evaluate their condition and performance.
