Do you know more details about the block heater?
Where is it located and can I add it to mine 2.7 with no problems?
What is its power consumption (wattage)? How much does it warm up the coolant?
As far as I know it heats the coolant, not the block itself, right?
While I don't have a block heater installed in my Rondo, since it is garaged and I now live in a moderate climate, when I lived in Ontario I used to install them myself. It's usually a simple operation to poke a hole in a frost plug and pry it out. The block heater slips in and is tightened with a bolt located in the centre. The seal is effected by a compressed O-ring. It's then just a simple matter to plug in the power cord and route it to a convenient spot on the exterior of the car, usually around the radiatior grille.
If you don't want to use a timer, there are extension cords specifically designed for block heaters. They have a temperature sensor built into them, so they only turn on below a preset ambient temperature. That way, if it's just cold when you plug it in at night, it won't turn on, but when it becomes bone-chilling, it will kick in.
Although a block heater may not be a necessity (to start the car), I used to take satisfaction in knowing that my engine was warming up quicker, thereby minimizing emissions, fuel consumption, engine wear and condensation in the oil. The fact that the heater kicked in sooner was an added bonus.
Yes, the heater warms up the coolant, which will circulate through the engine, to some degree, through convection. I don't remember the wattage, but it was something around 40 or 60W, as I recollect.
