Benefits of a Heated Engine

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.


Lower Radiator Hose Heater

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 175 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. This lower radiator hose heater is going to preheat your radiator in cold temperatures by heating your coolant and circulating warm coolant. It will keep your hoses from freezing and assist with smoother startups while allowing your cap to heat up and defrost faster. This is going to be an easy installation with the included hose clamps, as you see here. The heater is going to splice into your 2 1/2 inch in diameter lower radiator hose to heat your coolant and the heated coolant is 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 175 degrees Fahrenheit to keep the coolant at an optimal temperature, which is going to allow the heater to operate safely overnight to ensure no hoses freeze while your vehicle sits.

Then once you turn the engine, turn the ignition, in the morning, your vehicle's water pump will cycle the heated coolant through the engine block and heater core.

This 5 foot long, three-pronged plug can be routed through your grill and plugged into your standard 120 volt AC outlet or extension cord.

Great heater



by:



by:

It is a great product. I only gave it 4 stars because it won't fit in the location I need to put it. So I put it on my wife's car instead of my tractor. IT works great.



by:

Best way to get fast starts on those frosty winter mornings.



by:

Appears to be a quality product. I have not used it yet.



by:

I ordered this for my John Deere lawn tractor. I use it in the winter to blow snow but have to keep it in an UNHEATED shed. The heater works awesome and is compact enough to mount behind the side panel with absolutely no interference with anything. I Highly recommend this heater and etrailer.com to buy it from, they are great to work with and the item came quickly.



by:

Quality. I hope it works as well as it looks! Will install soon.



by:

It’s working Ok but I think the block heater would have been better, as it heats a little but I guess with the car outside and being so cold out it really can’t get that warm being in the lower radiator hose instead of the engine block itself. But at the time I installed it was middle of winter and did’nt have the time or weather to install one in the block instead as it would have been a project to do it that way .Maybe in the warmer weather I will switch to the block heater instead.



by:

I got this heater about a year ago but only installed it about a month ago. I have it in a
John Deere tractor with a 21 HP diesel engine. Here in Canada our temperature is measured in celsius and at minus 25 C which is about minus 12 F this little heater melted the snow and ice off the engine cover. I would recommend this heater to anyone. it is an excellent device.



by:

This is a great cats heater would I buy this product again from this company yes I would keeps my engine block warm

by:

Installed on a Mitsubishi 6 Cylinder diesel marine engine and worked like a charm. Some mornings experienced -25 degree Celsius temperature and engine would start first try, highly recommend.



by:

Received the heater today. Looks good. Will install in the next couple of days. It will go on my small ford tractor to replace the bad one on it now. Thanks for the good service



by:

This was a replacement as my previous one was damaged. In general, a great warmer for my 2003 VW TDI. I typically only use it when it's below 20F. It's nice coming to a car that is warm from the get go.



by:

My in-line lower radiator water heater arrived earlier than expected. It was packaged well and protected to ensure that it wouldn't be damaged. I was very pleased with the speed and accuracy of my order.



by:

After reading the instructions it was a very easy install. Took about 1hr to install let it run for 40 minutes to check for any leaks and get the air out. This is a DIY project.



by:

Does what it is supposed to do-keeps the radiator fluid temp above freezing.



by:

Great product and works perfectly!



by:

They did a great job in keeping us informed on the back order. They also quickly sent a different kit, when we realized we had ordered the wrong one.



by:

The heater fit and worked well, that's all one can ask of it. Thanks

I was told that it would have to be measured on the tractor to find the size.
