Maradyne Cooling Fans
Maradyne High Performance Fans is a brand owned by Cleveland OH-based DCM Manufacturing, Inc., a wholly owned subsidiary of Dreison International, Inc. Their other brands include SuperTrapp mufflers, Pow-R-Quik starters, Turbo air precleaners, and Air-O-Matic power steering, among others. Our Loyal Customers have been using Maradyne products for a while; here’s where you can see what they have to say.
Maradyne is well-known for their electric radiator fan lineup. Changing over to an electric radiator fan is a great way to rid yourself of 20 lbs. of unnecessary weight, and gain some power. Simply put, you don’t need a fan of any sort most of the time. The natural airflow through your radiator at any speed over 20 mph or so is sufficient to keep your engine cool. Race cars, which never get asked to idle or chug through slow traffic, don’t have fans. Fans need power to spin them, and the more air they move, the more they consume, regardless of how they’re powered. If your vehicle uses a belt-driven viscous-coupled fan, you may be able to gain several miles per gallon and gain as much as 15 hp by switching to an electric fan. It’s not that the electric fan is consuming less power than the belt-driven fan when it’s moving air: it simply uses none at all except when it’s needed.

Sure, the whole point of a viscous fan is that it decouples from the engine when the coolant temperature is low enough, saving on power. But when left to cool, it couples back to the engine as the silicone fluid inside runs back into the center. So you’re spinning at full revs right when you don’t need to: at engine startup. That’s that big rushing noise that goes away after 3-4 minutes in the morning. Even when the clutch lets the fan spin freely after warmup but before things get hot, it still takes power to spin those blades, as well as the parasitic losses in the belt and pulley. An electric fan uses power only when the engine’s coolant has gotten to the temperature that toggles the electric thermostat switch, generally well below that boilover point, but a little warmer than normal operation. You’ll gain mileage. And power – diesel mechanics are taught that it takes about 1 hp per inch of diameter to spin a cooling fan. Owners who have switched report 1-2 mpg gain in fuel economy, and improved throttle response and improved acceleration.
Maradyne also has a Marine products line: they have a line of marine cabin heaters, warmed by the engine’s cooling system and with 12V squirrel-cage fans, that are perfect for automotive uses. Add a fan to the back of that cold passenger van or RV. Or add a heater to that piece of construction equipment or ATV you’ve added canvas sides and a windshield to. These self-contained units need only a 12V connection and a pair of 5/8” rubber hoses to the engine to provide plenty of heat and defrost capability. They even can be ducted up to the windows, which is a safety plus for wintertime operation.
Ever use one of those $20 12V air pumps? Sure, it got your tire filled up, eventually. But it got hot, it was noisy, and it took what seemed like forever to actually add any air to your truck tires. It was simply too small and too cheaply made. There’s no convenience like having a portable source of compressed air. And it’s even a necessity if you spend much time off-road or on the farm where electricity can be miles away. Maradyne’s Junior Jet pump is built to industrial standards, and will pump up a big tire in a short time without overheating, and do it after years of bouncing around in your spare tire well.
I was unsure initially as it required a water line. However, it is quite easy to set up. I use the defrost outlet on the side to defrost. I think that is a really clever solution. Shuts tight when there is no hose connected and can hook up a hose when I need to defrost. Compact, rugged and very well designed.
I had a single electric electric fan on my 1979 Vette (Moderate Build Street and Strip). Temperatures had previously reached around 260 degrees during heavy acceleration and in stop-and-go traffic. After I've installed the dual Jetstreme with temp switch, the car warms up quickly to 200 and cools back down to 180 right away as soon as the fans are activated.
I was running a 10" fan on the cooling system but then decided to upgrade to 12" size. This fan runs a lot smoother and quieter. The cycle time is shorter due to the amount of flow I am getting through my radiator, and the cooling system is where it needs to be now. Well worth the money spent.
I've installed it on my '78 Malibu with a LS1 in it. Easy install, and fit the radiator just right. Drilled 4 holes, bolted it in, connected wires to the computer wires. Was a snap.
