I believe it circulates coolant to keep the cabin warm if you're returning to the car shortly.

Sixto,The Kat's (brand name) tank type engine heater is about the same size and shape as a soda can. it has a heating element inside of it just like an engine block heater that gets mounted into a freeze plug hole. it has a inlet pipe nipple on the bottom and an outlet pipe nipple on the top. The heater gets positioned near the lower radiator hose, then you tee from the lower radiator hose and plumb to the bottom inlet on the heater. the top outlet gets plumbed to s coolant hose nearest the top of the engine. When the heater is plugged into an electrical outlet the heater warms the coolant causing it to rise and circulate thru the engine.
I hope this gives you a better understanding of what I am trying to accomplish.
Thank you for your time and help on this.
