Keeping Marine Engines Cool on the River: Radiator & Cooling Solutions by IHT Services

Running inland riverways takes more than a reliable crew and sturdy hull. After all, your marine engine’s performance depends on a cooling system built to handle the heat.

At IHT Services in St. Louis, Missouri, we specialize in marine radiator and cooling solutions designed to meet the demands of inland waterways. Specifically, we serve operators on the Mississippi, Ohio, Illinois, Missouri, and Tennessee Rivers. Our mission is simple: keep your marine vessels running cool, efficient, and reliable—no matter what the river throws your way.

The Heart of Marine Performance: Cooling That Works

Diesel-powered marine engines generate intense heat, especially on long, high-demand routes. Without a doubt, proper heat exchangers or marine engine cooling systems are essential. Without them, performance suffers. You risk reduced functionality, increased fuel consumption, and unexpected overheating.

That’s why IHT Services offers expertly engineered marine cooling systems and heat exchangers for vessels powered by:

• EMD
• Alco
• Rolls-Royce
• CAT (Caterpillar)
• Cummins
• MTU
• General Electric (G&E)

From push boats and towboats to yachts and large industrial marine vessels, we’re trusted by the marine industry to extend lifespan, improve functionality, and prevent costly failures.

What Makes IHT Services Different?

• 🔧 Marine Cooling System Expertise
  We don’t just service radiators — we understand marine diesel systems inside and out. That means better diagnostics, faster repairs, and long-term marine solutions tailored to your vessel.
• 🌊 Built for River Conditions
  The inland river system can be brutal — fluctuating temperatures, raw water debris, corrosion, and long duty cycles. Our coolers and air conditioning support systems are designed to perform in these exact conditions.
• ⚙️ Repairs, Maintenance & Custom Solutions
  Whether you need emergency radiator repairs, scheduled maintenance, or a custom-built system including expansion tanks, hoses, or closed cooling systems, we deliver with speed and precision.

Engine Overheating? We Can Fix That.

Some of the most common marine cooling issues we handle include:

• Clogged or corroded radiator cores
• Poor coolant flow or pressure loss
• Heat exchanger fouling from raw water
• Seal, gasket, and hose failure
• Cracked tanks or tubing
• Inefficient air conditioning and coolers causing engine overheating

We use advanced cleaning, testing, and fabrication methods to restore efficient cooling — often without replacing a single part.
