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.

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.
