CM-1 Love Jugs Cool-Master Chrome V-Twin Engine Cooling System for Harley-Davidson Motorcycles

NOTE:  All Love Jugs can be hard wired to your battery but you can also use your accessory plug  for a faster, easier install if you select appropriate wiring adapter in the drop down menu. Motorcycles that do not have accessory plugs or that do not have 3, 4, 6 or an 8 pin plug will have to be hard wired.


  • 8 Pin Adaptor  – 8 pin adapter fits for 2014 to 2016 Touring Models (ADP-1)
  • 6 Pin Adaptor – 6 pin adapter for 2014-2017 Softails, Dynas, Low Boys, Fat Bobs and other non-Touring models (AD6P)
  • 3 Pin Adaptor – 3 pin adapter for 2017-Newer Milwaukee-8 Touring Models (AD3P)


1. Look at your Harley’s horn mounting bracket. If you see a rod bolted to the center of the horn bracket that connects to a bracket welded to your frame, the rod is in the way of the FMK, so the FMK will not fit your bike. In that case the Vibration Master is your best choice. Do not order the FMK if your bike has that stabilizer rod from the engine to the frame. (See image above that shows the bracket with and without the stabilizing rod)
2. The Frame Mount Kit is engineered to fit Harleys with a square back bone frame section located directly under the tank. Using a flashlight, look at the frame that is directly above the horn, you should see a flat surface, that’s the bottom section of the square tube. (NOTE: If you see tubes to the rear of the tank, you are not looking in the right place.) These tubes are welded to the square tube section of your frame. Again, look directly above the center of the cylinders. Once you have determined that your bike has that square tube section, and does not have the stabilizer rod, chances are very good that you can use the FMK. You just need to verify that there is no tie rod or other obstructions such as an ignition switch in that area. Here are the EXCEPTIONS:
If you have the new engine with the water cooled heads, The FMK will NOT fit your bike. There are cooling hoses in the area that the FMK needs to be mounted. Also, these rubber mounted, water cooled models shake excessively at idle. If your bike is water cooled then you will need to purchase the Water Cooled Frame Mounting Kit.

LOVE JUGS have been designed and manufactured to meet the highest standards of quality throughout. For example, LOVE JUGS are made of the best quality materials with no skimping anywhere.

For those that demand the best and most effective engine cooling system in the world, the Cool Master stands alone at the top of the heap. Amsoil secretly tested the COOL MASTER in their start of the art laboratory. Their findings document a 140 degree drop in engine temperatures and a whopping reduction of 53.2 degree in oil temperatures. No oil cooler can come close to the oil temperature reduction of the Cool Master. All of our models will out perform any oil cooler.

POWER: LOVE JUGS manufactures the most powerful, and by far the most effective, high performance, waterproof fans available. We do not use “Off the shelf” fans that all our competitors use. At 252 CMFs, our fans put out over twice the air as the nearest “competitor”. Don’t be fooled by the comments of overkill, your hot beast needs every bit of the velocity that we provide. But it’s not only how much air, but where that air flow is directed. Our engineers have meticulously located the unit to sit at precisely the optimum placement to concentrate the LOVE JUGS powerful air streams, at the hottest area of your engine’s cylinders. Only a two fan system can properly direct the air to the critical heat producing areas; and only Love Jugs has the power to do so very effectively. This system uses a low amperage draw to operate. It uses a maximum of 3.2 Amps.

CONSTRUCTION: Love Jugs are designed and manufactured to be the highest quality in every regard. The body is all Aircraft quality Stainless Steel construction polished to a high chrome finish. Compare this material to others whose body construction is either aluminum or mild steel. Although it’s more expensive, we exclusively use stainless steel because, unlike the other painted or chromed metals, it will never blister, chip. or rust. Ten years from now LOVE JUGS will still look brand new. Another important fact that sets our product apart from the field is that no welding is used in our manufacturing process. This is especially important considering the extreme vibrating environment generated by a Harley engine. Weld free manufacture prevents material fatigue, as well as the failure factor common in welded parts. These perils are not an issue for LOVE JUGS.

FANS: This is arguably the most important single element in all the systems. Let the facts speak for themselves. First of all LOVE JUGS fans are twice as powerful than their nearest competitor. In addition, they are 100% waterproof. We were shocked to discover that some other manufacturers actually have been employing less expensive indoor rated fans which will short out when exposed to water. For over two years our engineers aspired to master the art of cooling your hot beast. Using thermodynamic photography, along with in-shop and on-the-road testing, our engineers determined just how much power and what precise placement a cooling system needs to have in order to make your engine think it’s being cooled by an equivalent amount of air when standing still as it would tooling down the highway.

PERFORMANCE: Love Jugs are by far the most powerful and effective cooling system available. Our competition say’s that Love Jugs’ superior power is overkill, nothing could be further from the truth. Of course they have to make up a ridiculously false statement like that. What else can they say? They can’t even come close to matching Love Jugs’ power and effectiveness. Here is what the Buell engineers quote in their US Patent application for a forced air cooling system. “The higher the volume of air flowing over an air cooled motorcycle engine, the more effective the cooling fins are at transferring heat from the engine to the air.”

WATERPROOFING: Love Jugs’ IP 68 fans have always been 100% waterproof from our first prototype on. They will actually run while submerged underwater! Believe it or not, some competing systems use indoor rated fans which will short out when exposed to water – even during a washing.

OIL TEMPERATURE: Oil temperature is another vitally important issue that LOVE JUGS solves. Even a fan assisted oil cooler cannot equal the cooler oil temps. of a Love Jugs equipped air cooled V-twin engine. It has been proven and well known that a LOVE JUGS cooling system will lower oil temperatures, which dramatically increases oil pressure especially at idle, due to the cooler operating engine temperatures of LOVE JUGS equipped bikes. Increased oil viscosity due to cooler oil is critical for the longevity of your engine.

WARRANTY: Love Jugs are rated for a minimum of 20,000 hours of life. We provide you with a full year 100% warranty on electrical components and three (3) year warranty on all other parts
