Product Description

A lower radiator hose heater is an electric heater that heats the engine of a vehicle to give quicker starts and protects your engine from damage that can occur during cold weather starts. Warmed engines also deliver better fuel economy, plus improves oil flow to provide better lubrication to the engine, which reduces wear and increases engine life.

Works Great!
I put it on a timer for 3 hours before I leave for work. The engine starts right up with no strain and the cabin warms up shortly after, on a -4 F degree morning. Make sure you follow the instructions closely and install the heater, with the head down, at an angle, close to the water pump. Otherwise you may shorten the life of the heating element.
I installed the Kats 14500, (600Watt heater for 1-1/4"hose) on the 3.1L V6, lower radiator hose of my 97 Olds Cutlass Supreme. (Some 3.1L,V6 Chevys and Pontiacs should be a similar install)
Since my car was not on the list, I called Kat's about the installation on my car, and as long as it is installed properly, you follow the instructions, and install it at an angle close to the water pump, it will work just fine. The cooling system has to be purge of all air before you operate the heater.
Not an install for a beginner, but for someone who has some auto cooling system-repair know how.

Unfortunately this wouldn't fit my car. The lower radiator hose didn't have enough of a straight piece to install this properly. It would have been nice to have some kind of application chart to save me from paying return shipping. Also, it was extremely difficult to look up the diameter of the hose. They really need a chart or reference to insure proper fit.

Now that I have had a chance to use the heater I am quite happy with it's performance. I was somewhat skeptical due to the design change but the operation is great, the engine is nice and warm, starts easily and has heat coming out of the heater immediately after starting the engine. This is a compact unit that is easy to install and is moderately economical to run due to it's conservative 600 watt rating. Kat brand has been around for many years and has become the standard by which others are judged

I'm still trying to get this heater to work...I don't want it on all the time, so I have it set up on a timer. So far, 45 minutes on does not do much to get my heater going right away in the morning for the drive to work.

Installation was a pain for me. I have a compact car, so space was limited for me to work. It needs to be installed on the lower radiator hose, as close to the water pump as you can get.

I bought this unit because of the impending harsh winter weather that was expected for the NE this year, 2011-12. Thank goodness it didn't happen, I know it bummed out a lot of people, but the older I get the less of winter I need especially after living in Stowe, Vt. for 25 years. Anyhow, I've used these Kat's heaters before on other vehicles for years and they just keep on working like a TIMEX WATCH. The real neat thing about them is when you first start up your vehicle and this is made easier because of the relative heat that this thing puts into your cooling-heating system, you get cabin heat a whole lot faster than you would by not having one. You have to plug them in and pay for the electricity but when you wander out in the dark and sub-zero temps, guess what, chances are very, very good your rig is going to start, just the way it should only with a little help from that little heater hooked up to your radiator hose. Easy to install and highly reliable. Parker Diamond-Hampton, NH.

This little heater works great so far. It's been about -20 here and my little truck didnt want to starts but with this little heater on there it fires right up not. Time will tell how tough the plastic is, but so far a really good product.

Good heater. I have had it for quite awhile and have had no problems with it. Makes starting a diesel engine a snap.

After all of the time and hassle I spent installing it in my compact Jetta TDI. The first cold day I plugged it in... nothing. No heat at all. I am very disappointed with the product. Now I am out the cost of the heater and a radiator hose to return the car to original.
