SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

Necesito el diagrama del cicuito electrico de un motor isuzu 4jg2, del 2004, de una isuzu Bighorn, donde lo puedo conseguir


spanish on English forum? really?
I need circuit electrical diagram of a 4JG2 Isuzu engine, 2004, an Isuzu Bighorn , where I can get it.
what country? we cant guess that, and i guess you dont know engines ,EFI , spark and many parts are all different by that fact.
if the USA car on this USA forum is a 4JG2
then all this is found at alldata.com
it a diesel engine, and we dont have them here.
it is direct injected diesel. sold in most markets, but not here.
Our isuzu dealers are gone now, they left uSA. for passenger cars.
so cant go there.
then go to yours and ask them?
"In 2002, the Trooper was discontinued in the United States."
so now i know car is not a USA car. and that our books dont cover cars not sold here.
so why not ask Isuzu this, go to the dealer buy the FSM book.
or join any non USA forum for isuzu. trucks. troopers


try here, link is random

http://forum.planetisuzoo.com/viewtopic.php?t=16663

they speak english only there too.
i dont see any spanish speaking isuzu forums.

best wishes.

What are the head torque settings of the 4jk1 engine in the Isuzu kb250dteq?


welcome to the USA forum (calif) so....
what car. ? KB250 sounds Australian? is it? we cant guess country
South Africa?
4JK1-TCX (this engine?) (google searches do little there , zero)

A pickup truck.with 2.5L diesel. with direct injection?
and our books (this is USA forum) dont cover AUZ cars.
what year.? 2007 to now? (but what?)

the data of all cars. are indexed by
year, make and model and engine name 4jk1-tcx)
so we cant help you , lacking those facts.
we cant look it for you.
why not stated, country. first. then full engine name. all letters.

what if?
and what if they changed to TTY bolts, in say 2008,..
so what is TTY, its torque to yield. (use one time)
or the changed from KG torque, to degree's from hand tight. methods, and he pattern , do you need the pattern to torque, sure.


I see just these , generations.....
here is the list off the wiki, the CR might change this..spec... too....
  • The 4JK1-TC is a 2.5 L (2,499 cc), 95.4 mm bore, 87.4 mm stroke direct injection 16V diesel engine. It was used in the Isuzu D-Max and Chevrolet Colorado inThailand. Stock power was 116 hp (85 kW) and 280N·m at1800-2200rpm.
my guess is the TCX engine ! below>

Isuzu 3ltr turbo diesel no fuel to injectors


this is USA forum, and we dont have this car.
IT'S NOT A USA 2002 DIESEL trooper.
that and exact engine, size.
we have, 3 gas engines, 2.2L,3.2. and 3.5L
here. only and books that cover only those 3 engines.
so if a diesel dies.
what>?
check fuses.
scan it.
check filters
try test fuel to see if it runs on test fuel
test the glow plugs yet,?

if pump pressure is dead,?
check, power to the pump yet? (fuses are first)

there are 4,.6 and 8cyl. diesels by Isuzu.,
which is it>
they have names.
7 diffr. B engines, 3,xxxx liters.
and
5 diffr. 4Jxx series engines.
my guess is the engine is.
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

wiki says.
"
European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the more problematic 4JX1 3.0-liter of 159 PS or 117 kW)
4jg2 is indirect injected
4jX1 is direct.
apples and orange diffr.! injection classes. '

learn what's under that hood, then fix it?

what country
what engine, real names, not 3L vague-ness. please.

I need to know how to do a compression test on a 1993 isuzu trooper


Compression test is pretty easy. You need a compression gauge and a method of turning the engine. A remote starter (cable with switch) or a helper will do this for you. Make sure you have the ignition disconnected as you do not want the engine to start nor do you really want fuel being injected. A tablespoon of engine oil is also good. Measure the compression if it is low, add the tablespoon of oil in the cylinder. If the compression is good, it is a good sign that the rings are worn.

Best of luck, Jim
