Very cold weather mods
Gentlemen,

In case you have never heard of Defa Warmup its a system that is fitted to vehicles in Scandinavian countries which heats the engine block / charges the battery and puts on an internal convection heater to defrost the car.

It is controlled by a small digital box which you can set to come on twice a day [go to work and come home] and it also gives you outside temp and battery voltage.

It works off 220v with a waterproof socket on the front of the car, in cold countries hotels and workplaces have free outside electrical points.

The system is cleverly designed so it interlinks with protected cables and waterproof connections.

The battery charger is to assist keeping the battery warm as its capacity drops off in very cold weather -25c.

They sell every component separately so you can buil

d the system with just the engine heater or engine and internal heater.

I fitted the system to my 200tdi defender a couple of years ago - and it does work a treat [cost then was about £400]


Another cold weather modification [which is more belt and braces]and used by the bio-fuel drivers is to fit a fuel heater to stop diesel freezing.
You can get VW oil cooler which fits between the diesel fuel filter and the head, and this is feed engine cooling water to ensure the fuel going to engine is warm and not waxed up.

Looks a great idea but maybe a bit overkill for this country? Ray

Kenlowe used to make a mains block heater that heated and circulated the coolant

Also if you have a 2.4 or a 2.2 and venture in temperatures less than -20c ish.. You'll need a breather heater or a new engine when it freezes up

Interesting post Bumpymike Thumbs Up

You got any pictures of your installation?

Another route is to to install a Webasto Thermotop fuel burning heater to heat the block before starting Thumbs Up Running Restoration Thread http://www.defender2.net/forum/post323197.html#323197

I thought that was just for the 2.4, the 2.2 has a different arrangement?

No.

I fitted it for a trip in Feb 2014 to top of Norway via Finland / Sweden, and just planning another winter 'walk about' so thought it may of been of interest to folk who live high up in Scotland who looking for a warmer vehicle in the morning.

I considered the Thermotop but worried about battery drain and with a eberspacher in rear had already fitted an additional pickup into fuel tank and this was easier option to fit.

Will get some pictures in daylight if it stops raining !!!

Here is one for fuel heater.

Not sure, the pipe from the rocker cover to the airbox freezes up on the 2.4's, maybe the 2.2's are different , so I'd say if the pipe exists on the 2.2's check with LR

Not seen this brand before Thumbs Up

I've always steered away from the electric ones as i've found that even in the most northern parts of Scandinavia hook in power sockets are not always reliably available and the FBHs use very little battery, but at £400.00 it is a well priced alternative.

What winter 'walk about' are you planning??

More likely drive up to Finland and fancy do some ice driving on a Lake (in one of there cars) and then may go top of Norway again or Murmansk to see the Nuclear ice breaker or drive back around Finland to Helsinki and get ferry to Estonia and drive back via Latvia, Lithuania, Poland and Germany.
