MotorMax Logo


Unlike traditional water wetters, MotorMax is a natural heat sink that absorbs heat from internal engine parts and more efficiently carries it to the radiator for overall enhanced engine cooling performance. In particular, temperature differences between cylinders (hot spots) are reduced for better overall performance.

Unlike many water wetters which achieve water temperature reductions by coating water jackets or speeding water flow, MotorMax actually reduces water and oil temperatures. A true breakthrough in thermal technology, MotorMax allows water to absorb dramatically more heat without vaporization, hence its demonstrated ability to transfer heat away from critical engine components and reduce overall engine temperatures.

All the benefits of Motor Max

Faster warm up: In a thermostat controlled cooling system, MotorMax will absorb the heat of internal engine components and transfer it evenly throughout the engine. Since water with MotorMax is acting like a heat sink, engine temperatures will rise faster, reducing both the time for warm-up and cold start wear and tear. In addition, cab heater output is noticeably improved in severe cold due to MotorMax’s ability to carry more heat through the heater core than standard coolant mixtures.

Reduced water temperature: Once the thermostat opens, MotorMax will transfer the heat it has absorbed into the radiator. Motor Max’s ability to discharge heat dramatically when exposed to airflow allows the radiator to more efficiently remove heat from the MotorMax/coolant mixture. Individual results vary depending on the size and volume of your cooling system. In a variety of applications, MotorMax has reduced engine temperatures an average of 15-20 degrees, with reductions of up to 30 degrees seen in select installations.

Reduced internal engine parts temperature:
Acting like a heat sink, MotorMax has the ability to absorb heat from internal engine parts. Reducing operating temperatures of internal parts has a major impact on wear and tear. This becomes critical in the life span of such major internal components as valve springs, wrist pins, cylinder walls and pistons.

Reduced oil temperature: MotorMax, by absorbing heat from internal engine parts, will also help to reduce engine oil temperatures. Reduced oil temperature results in less chance of oil breakdown, decreasing damage caused by poor lubrication. Minimizes hot spots in engines: All engines have some variance in engine temperature from front to back or side-to-side. With its ability to absorb heat and transfer it, MotorMax reduces engine hot spots and virtually eliminates steam pockets. The ability to reduce hot spots is vital in the search for enhanced engine performance.

More comfortable passenger compartment temperatures: Now that your engine and many of its components are running cooler, the reduced temperature translates to cooler engine bay temperatures. This results in a more comfortable cab interior, with substantially increased air conditioning output in hot weather.

Reduces engine temperature rise at idle: MotorMax will keep your water temperature lower in conditions where there is little or no airflow. With its ability to pull more heat out of the engine and into the radiator, MotorMax helps keep your engine cooler while sitting still or at prolonged periods of high idle.

Why put MotorMax in my commercial or fleet vehicle? 

Commercial or fleet vehicles are subject to particularly severe operating conditions, exposing them to above-average temperature ranges and increased life-cycle operating demands. Through reduced engine bay temperatures, additional benefits of MotorMax include:
· Prolonged component life
· Reduced transmission operating temperature through cooler transmission oil temperatures.
· Increased useable alternator amperage output.
· Increased air conditioning efficiency, particularly critical with R-134 coolant systems.
· More efficient fuel combustion through equalized cylinder temperatures, enhancing engine performance and fuel economy.

While created and proven in the demanding environment of the race world, MotorMax dramatically enhances the performance of any motor using a closed-loop (radiator cooled) cooling system. Specific applications for Motor Max’s amazing performance include:

All Types of racing vehicles

How to add Motor Max

Simply add one quart of MotorMax radiator additive for standard automotive engine applications, or add MotorMax in a 1:10 ratio for severe duty, commercial trucking/fleet or racing engine applications. MotorMax radiator additive is a one time treatment, and works continuously until your engine cooling system is flushed according to your manufacturer’s suggested routine maintenance schedule. MotorMax is compatible with all mixtures and is equally effective when mixed with water alone where antifreeze is not required.
