I am looking into installing an engine block heater in my Trooper.
What does anyone know about these things? I am likely moving to Montana
soon and would like some options/opinions. How much $$$? How difficult to
install yourself? Where does it go in the engine? Is there one type of
heater that is better than another? Is there a "generic" available for
v,during this test
the line voltage was low so the power drawn was only about 540 w.
Leaving the heater plugged in brought diminishing temp increases,
due to increased losses (Stephan- Boltzman(?)law).
A petrol really shouldn't need heating, unlike a diesel which fires due to
heat and compression, a petrol has a spark to set it off. rather than a
heater I'd be looking at putting in a second battery as is found on some of
the Jap editions from the cold parts of over there.
with the 3.5 you know to watch you oil tho? they drink it down pretty fast.
I've heard plenty of horror stories, even more than the 2.8 petrols tendacy
to crack heads.
Your American GM engines don't seem to stand up very well. the 2.2 is
anemic, the 2.8 V6 cracks, and the 3.5 has oil probs.
I've been lucky -- I don't really have the oil problem many complain of.
Occasionally I'll be down about 1/2 quart, but I can go between the 3k-4k
mile oil changes with little oil loss.
As for the 3.5 engine, it's all Isuzu, and a good thing, too. It should be
the same petrol engine available elsewhere in the world.
The heater will be used to keep the engine "warm" during cold nights
averaging zero here (approx. 16-17 below zero, celsius) to ease both wear
and emissions during morning starts. Apparently emissions can be reduced by
as much as 70% when using a heater for about 3-4 hours prior to start when
the temperature drops below 20 degrees F (about -6 C or so, I think).
Thanks for the feedback.
So, you're headed into summer down there... Beautiful part of the world.
Yep, summers beautiful, temps are into the low 20s *C, sun is out, the
beached are covered in Bikinis.
if it's just to keep it warm that way, just open the bonnet at night and
toss over an electric blanket connected to a timer set to start in the
morning a few hours before you normally start it up.
As to the 3.5 in NZ, it's sold, but it's rare, NZers just don't buy petrol
SUVs much, only Jeep with their big Wrangler and Cherokee V8 petrols sell
many, and those aren't common either, thier diesels are more popular than

Hi. I am based in Christchurch and am trying to get the engine block heater
working on my 95 bighorn. I don't have a manual (can't seem to download one,
frustratingly!!) and I don't know how it works. Is there an external cord /
plug? If the block heater relies on the battery, and the battery is not at
optimum charge after a cold night, isn't this counter-intuitive? Besides which,
the switch lights up when the engine is running, but otherwise not. Help!!!
