We own a 1996 3.1TD Trooper. It has had a variety of electrical faults which
I have slowly been fixing. I can not however confirm the Engine heater
works. When cold you can switch the engine heater on and the switch lights
up, this however seems to make no difference. The big question is, where is
the heater? I am unable to get a decent workshop manual for the diesel
trooper anywhere other than a genuine for around £100 (GBP)
Anyone got any ideas
The engine heater you mention is probably the exhaust restriction device,
when cold it partially closes the exhaust pipe so the hot gasses stay around
to heat the engine and the engine works a bt harder to overcome the
restriction. look along the mainfold/tailpipe for a gadget.
'88 2.8TD Bighorn LWB
know that theres some confusion about the gadget on the tailpipe tho, some
think it's supposed to be an engine brake, it's actually a heater, you're
not supposed to rev hard or go full bore until the engines warm and the
thermostat releases the restriction with that method. I suppose all the
gasses at full revs could bend or damage the check valve/restrictor.
So you could Either pull the sump (fun, and messy) and look for a ceramic
heater, or look along the exhaust. It'll likely be one or the other.
It is not a heater but a solenoid operated retricor you will find it in the
exhaust more or less unerneath the drivers seat My advice is Dont Use it for
one thing only necessary at temps cold enough to freeze penguins But the
main reson is that they are Prone to Sticking Shut once that happens you
will have aa real problem been there As for sump heaters quite intriguing
how long does that have to operate in order to aid cold staring & would that
then leave any power in the Battery ?? I do know that most sumps have a
IIRC mostly they run straight off the alternator. I don't know anything
about the 3.0 however, the 3.1 is merely the 2.8 block with a larger piston
size and different head. but the 3.0 is a new design entirely.
First of all apologies for typing errors must junk this keyboard
there is a ceramic heater in uk spec & some imports this is housed in the
heater box above transmission tunnel when heater is switched to full heat it
is switched on handy on cold mornings as it provides instant heat
Be nice on cold winters. But as for imports I suppose you mean used Jap
cars? I thought they came with remote starting in the cold parts of japan,
start the car while enjoying your Sushi breakfast and duck out to the cosy
warm car once it's reached a civilised heat.... A number of Used Jap imports
to NZ came with dual batteries to provide extra power to crank with on cold
days. Apparently needed when parking on Mt Fuji...
My 3.0 Trooper is an original UK model and has two batteries. I do not
normally park near Mt Fuji. :-)
The engine heater switch in my car has a picture of an engine with a heater
coil in the middle of it. The handbook describes it as an "engine warming-up
system" which operates when ambient temperature is below 15C and engine
cooling temperature is below 80C. This does not make it sound as if it is a
supplement to the car heater. The connection with coolant temperature makes
me suspect that the heater is somewhere inside the coolant system. Of
course, this would have the added benefit of speeding up the heating of the
car heater system.
connection with cooltant temp is via a thermostat operating the solenoid. If
your car is worm enough, engaging that switch does nothing, since the
thermostat tells the heating system not to engage.
Yes, and in addition I believe it only works below certain throttle/rpm
limits - e.g. if you floor it the solenoids are released. I also believe
the intake is choked (and/or receives additional fuel) as well as the
exhaust. How the hell this warms the engine up faster I do not know! But
experimentation in our relatively mild south UK climate indicates that it
makes ****-all difference whether you put it on or off.
I know little about the 3Ltr other than to avoid them according to the
reports the engine is a lemon and almost solely responsible for Isuzus /
Troopers demise but from your description your 3.0 seems to have similar
arrangement to the 3.1 will check on Mon with a man who will definitely
knowand revert. Sadly the reports about the 3.0 have been so bad that they
have convinced me not to buy & my next purchase due about now will almost
certainly be a Colorado which saddens me having had 3 fine Troopers which
have served me well over the years I plan to retain my current troop for old
times sake & make sure she ages gracefully :-( I know its sad !!! but what
