I don't have one but intend on buying one this fall, basically it warms up your vehicle via coolant being warmed by the webasto, so you don't have to run your engine to warm the interior. Also you get a warm engine which always starts in Sub-Zero temps. You can get a "autostart" for the webasto so you don't have to physically go outside. You can also get a timer and have it warm up the car at certain times. It also runs about 10hours per gallon of fuel. We have one on our Volvo loader and it's always nice and warm when it's time to plow the snow.

It is a pre-starting warm up !!!

Let say its -25c outside, I run my Webasto for 1 hrs before I go to work. When I get in my Jeep , it start like if it was running 5 min ago. No fast idling , it's close to operating temp and I got some warm air coming from the vent ( always remember the rest, trans. diff. P.S. are not.....)

You don't really have to keep it warm as it don't take that long to warm up and a switch a remote or a timer can be used to operate it.
The Webasto coolant heater is not intended to be used to keep warm to sleep in the vehicule, they make other kind of heater for that use.

It is probably as loud as a new car running !

The main question I would ask myself if I were you is if I'd ever be in a place where electricity is not available (so block heater use is not possible). Also, if I'd be parking the jeep for extended periods of time in very cold weather. If yes, then the webasto heater is a good choice. This is a good addition to have when you go hunting or winter camping. Keep in mind that webasto also works with diesel and low temperatures may negatively affect the fluidity of diesel, so with improperly winterized diesel you won't be able to use the webasto unit either. It is easier to have a webasto than carry a small gasoline generator to use it for your block heater.

If Jeff (turbo diesel freak) still has some webasto units, I'd get one from him. So contact Jeff and see if he has any left. Supposedly the units come with instructions, but I'm also sure Jeff will give you plenty instructions on the top of the manufacturer ones, if you ask him. There is also a thread regarding webasto installation in the crd forum, look it up and you'll find out plenty details. I'd advise you to install it yourself, if you're relatively handy, you'll install it better than any shop.

If you want cabin heat while the engine is not running, there are kits for webasto that run a coolant hose inside the cabin for heat, similar to what truck drivers have on the big 18 wheelers. I am not sure how exactly the kit is, it may use the existing vehicle heater and hoses. I'm also not sure what source of power they use for the heater blower. I'd look up on the Internet for more details.

I think that's the thread, but as I see now there are less details in it than I thought. But maybe enough for you to get an idea.

The main difference other than not needing external power is that the Webasto produce 17 000 btu and it has his own pump that circulate the engine coolant. It will bring the coolant up to 170F and then goes on and off to keep it there and the pump keep running. it will also stop if the battery reach a certain voltage.

It took me a full day to do the install it's a lot of work , plumbing , fuel line , electrical , bracket for the unit ....

and I suggest you install a lift pump as you need to take the fuel tank down to run a stand pipe thru the tank. the lift pump is a great upgrade, no more air in the fuel system , no more pumping the fuel head , better cold start and better throttle response !

Installing a Webasto TSL17 in your Liberty CRD will absolutely eliminate cold weather starting problems forever. No more glow plug issues!! Heck, you can replace your fragile ceramic plugs that work O.K. with the durable steel ones that work terribly, but that would not matter anyway because the engine's computer will never have to turn them on if you use the Webasto heater first.

To give you an idea of the power of the TSL17, it was designed to be used in 3,500 to 4,000 lb commercial diesel engines, and will warm up one of those from stone cold in under 2 hours in the coldest weather. I used a TSL17 when I was hauling 80,000 lb loads of pipeline pipe up to Northern Alberta, and it never failed me. I would set it to start 2 hours before I got up, parked at a roadside rest stop for truckers with no electrical outlets. It didn't matter that it was -40 degrees outside; the engine warmed up and started immediately as if it had already been running for a while. If it can do this for a large commercial diesel engine, it will have absolutely no problems for passenger vehicle diesel engines. Your Liberty CRD engine is roughly 600 lbs; getting up to the 170 degree limit a Webasto TSL17 is designed to heat to will be a matter of under 40 minutes in -40 degree weather.

The TSL17 is called that because it is designed to put out 17,000 BTU of heat at full blast, and that is equivalent to 5.0 KW of power. This is fully 12.5 times the power of your block heater, so it is little wonder why the Liberty CRD engine heats up so fast using a TSL17. Comparing a TSL17 to your block heater is like comparing a .44 Magnum cartridge to a .22 Long Rifle cartridge.

We're only talking about one heater:

Webasto is the manufacturer
Thermo Top C is the model name (Webasto makees many different models of heaters for various applications)
TSL-17 is the model number for the heater Thermo Top C
923369 is the part number for the kit (includes TSL-17 heater, On/Off Switch, Fuel Metering Pump w/Mounting Bracket, Fuel Line, Fuel Filter, Universal Fuel Standpipe, Exhaust Tubing, Combustion Air Tubing, Wiring Harness w/ Fuse Holder, etc.)

17,000 BTU is not overkill for the engine, it just heats the coolant up to temperature that much quicker. The heater has a built in thermostat so the coolant will not exceed the set-point (~165F).

Seth is absolutely correct here, and I did not mean to imply that the TSL17 is overkill on the Liberty CRD engine. The .44 Magnum/.22 Long Rifle analogy is simply the comparison of the TSL17 vs. the O.E. block heater, which barely does the job, and takes hours to do so.

The power of the TSL17 is a great convenience factor here, as you can start it and have the engine up to 170 degrees Fahrenheit by the time you take to eat breakfast. It is thermostatically controlled, so you do not have to worry about any overheat situations.

You CAN get smaller Webasto engine coolant heaters, but you would have to import them from Europe. Parts will not be readily available, they won't be as powerful because they are smaller and will not put out as much heat, and they will likely cost twice as much. It is much better to go with what is common over here in North America, and use the Weeks battery tray or mount the TSL17 in an aftermarket bumper.

bushtit: "The good news is that the lift pump is already installed in my Jeep. The bad news is, that after your description on the amount of time/work involved, I will very likely not be willing to take such a project on by myself. Too many chances to run into problems without ability to finish it and then the necessity to desperately trying to find someone quickly to sort everything out and finish the project. Been there, done that, not looking to be in that specific situation again."

Sorry, bushtit, I missed this when I responded to your PM.

Your trepidation with performing a Webasto install is understandable; it is indeed a big job. You can get someone to do it for you; yes it is more expensive that way, but at least you will have something installed that is proven to reduce fuel consumption and extend the life of your engine.

In commercial applications a Webasto heater has proven to get a complete return on the money spent in as little as 3 months. In passenger vehicle applications the return will take longer, but those returns are definitely there. There is no denying the convenience factor and reduction of overall fuel consumption of using a Webasto engine coolant heater. This has been proven countless times in both commercial and passenger vehicle applications. Even the hated EPA recognizes the TSL17 as a proven idle reduction device, reducing both fuel consumption and emissions.

Seth: Where would one find the kits that you mentioned in your post? Thanks.

eBay, Jeff, or locally. I found my local prices were about 2x what you can find them for on eBay.
