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 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.

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.

Review from a similar Lower Radiator Hose in Vehicle Heaters


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.

Review from a similar Lower Radiator Hose in Vehicle Heaters


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.


Comments
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.

Review from a similar Lower Radiator Hose in Vehicle Heaters


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.


Comments
It The heater is still working fine. It gets used alot and has never failed me. I would recommend to onyone needing a heater for a small engine.

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.

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.
