Splices into your lower radiator hose to circulate warm coolant through your radiator in the winter. Allows easier start-ups and prevents frozen hoses. Once the engine is on, warm coolant cycles through the heater core to heat your cab faster.

Notes:
Start your engine easier and warm your cab faster in cold weather with this lower radiator hose heater. Heating your engine coolant keeps it from thickening and freezing, resulting in more reliable start-ups and smoother operation altogether. It also lessens the workload and extends the life of your vehicle's battery. And because starting your engine when it's warm creates less condensation in the engine block than starting it when it's cold, your engine will get better initial fuel vaporization, which causes fewer emissions and less pollution.
This heater splices into your lower radiator hose to heat your coolant. The heated coolant pushes the cold coolant through the radiator and thermosiphons it back to the heater. The heater's internal thermostat automatically shuts the heater off at 270 degrees Fahrenheit to keep the coolant at an optimal temperature, which allows the heater to operate safely overnight to ensure that no hoses freeze while your vehicle sits. Once you turn the ignition in the morning, your vehicle's water pump will cycle the heated coolant through the engine block and heater core. This will allow for a smooth startup, and it will also help your cab to heat and defrost faster.

Hi, everybody. Andy here with etrailer.com. And today we're gonna take a look at this Kat's Heaters lower radiator hose heater. Now, this lower radiator hose heater is going to preheat your radiator in cold temperatures by heating your coolant and circulating warm coolant. It's going to keep your hoses from freezing and assist with smoother start ups while allowing your cab to heat up and defrost faster. Now, this is going to be an easy installation with the included hose clamps that you see there.
This heater is going to splice into your one-inch diameter lower radiator hose to heat your coolant. The heated coolant is then going to push the cold coolant through the radiator and thermosiphons it back to the heater. The heater's internal thermostat automatically shuts the heater off at 270 degrees Fahrenheit to keep the coolant at an optimal temperature. So, that's going to allow this heater to operate safely overnight to ensure that no hoses freezes while your vehicle sits. Now, once you turn the ignition on in the morning, your vehicle's water pump will cycle the heated coolant through the engine block and the heater core.
Now, the heating element itself is enclosed in the casing to prevent burnout. You do not wanna use this heater with 100% antifreeze solution. You also do not wanna start your engine with the heater plugged in. Then you're just going to simply route this three-prong plug through your grill and plug it into your standard 120 volt AC outlet or extension cord. This cord can be replaced to avoid buying a new heater if it gets damaged.
So, just to let you know, we do carry the cord separately if you are ever in need of it. And on your screen, I am including the item number for just the cord itself. And you can just pop that item number that you see there on your screen in the search field of our website. It'll take you to that cord. But the cord does come with this heater.
This is made here in the USA. And it's made of a die-cast aluminum construction so it's going to be impact and corrosion resistant. It will maintain strength in high heat. It's molded into one piece to prevent any leaks. This is CSA certified. And this has a wattage of 400 watts. And this also includes installation instructions to walk you through the simple installation procedure. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

I finally got the block heater installed instead of the in line one and its much better with the heating process, so just removed the in line one and would like sell it or give it to someone who it would work better for. Guess with it being a 350 engine and a large radiatior for a high performance car it just wasnt enough to keep it warm enough for the short ride to work. Really isnt that cold around here and the block heater seems to work better.
