Whose the genius that decided to put the thermostat in the center of the engine! How is it supposed to be removed?
Well, as you said, Isuzu engineers are not the brightest. We are in the process of trying to figure out how the oil got full of water! If anyone has experience in the 3.2 V6 2000 model and where the likely failed spot for the cooling system is, I'm all ears.
To your problem, the thermostat housing is located under the intake manifold, yes under it. You will have to remove the intake and fuel injection system (lots of fun) to get at the hard pipe lines under and in the front of the engine. Once there removal and replacement of the thermostat is easy.
Water in the oil system sounds a lot. Like a blown headgasket has it been overheating?
if the VIN W or X engine ,DOHC thermostat gasket fails
see this photo, best is to look first
the wide DOHC heads were fitted on the old block . and must have a huge new intake plenum. (it really sucks big time air )
MUST
but guess what, not a new engine block
id put a racing line thermostat and housing on it up front.
i can hear the sounds, of anything
what will be will be, fate, runs world not ****** statistics.
water can reach oil for many reason
blow head gasket. (4 tests for that ask)
or you or previous owner runs water for coolant and WINTER ICE cracks head , block or both,
done many like that.
here is the early 3.2 and later 98+
as you can see the VALLEY does NOT Go to the PAN, at all, one hole there is the knock sensor. also burried deep.
if you drain the coolant first, there is far less mess.
The gringos what max power, so you got new heads. and this is the price,. complex stat.
if I had water in oil
compression test.
then , leakdown test and find out if air
lands in the oil side.(sonic tests for hisssssss)
if yes, can be cracked head. or block.
but warped heads top list.
you can hear the hisssss in these places
oil filler
dip stick tube.
exhaust ports
intake ports,
or even at the head/block juncture.
so did you overheat it???????
or run pure water as coolant not 50% AF

i bet he sold this dog.
correct if poster thinks this is hard.
try some water pumps on FWD cars.
my guess, is OP never heard of a the factory service manual.
it covers all that, mine is 8000 pages long.
but one page on this. hark.
Under the intake and I am going to agree with Moterhead 1 on the not so bright comment and might I suggest replacing the hoses that go from intake as well hope you have a mechanic in the family or get a loan LOL

Don't know about that. Lets say i certainly am getting that "sinking feeling."
Where is the thermostat? How do you replace it??? Mine is stuck closed!!
I just purchased a thermostat and need to know where to change it.
I have the same issue on a 1999 V6 Rodeo. Rediculous engine design. By the way, to the guy that said "same people who bombed Pearl Harbor". Have you ever looked at the "Built in.." sticker on the rear door windows? Made in INDIANA, much of which was designed and built by GM - The same company which is now asking us to bail them out of the financial position they've created for themselves.
Anyway, I have the same issue with my thermostat needing replacement. I have a Haynes book on the vehicle but the info in there seems sketchy at best. Local shops around Denver want anywhere from $140 to $240 at the dealer (Tynan's in Aurora, CO) just for the labor to install the thermostat.
While this vehicle has been pretty reliable, and I have 200k miles, the exorbitant costs for minor repairs leads me to believe this is at least one reason why Isuzu has not been successful in the hottest vehicle market in America. Too bad Isuzu execs don't get how easy it would be to make these vehicles big sellers in the U.S. Hey Joe Isuzu, you guys hiring??
Have low coolant temp. is at 155 deg. Will need to replace the thermostat also. Looks like a night mare!!!!
Anyone do the change, any help would be appreciated,

Who is the genius , ok can't spell sorry.
anyway 100-300 dollars is a good deal considering all the labor involved. The Haynes manual i have doesn't really go into to much detail on how to replace this thermostat, or for that matter how to disassemble the fuel injection system. So there it be under the intake manifold. Had a mechanic do it, his bloody knuckles hate me, and my car now. P.S If your having this repair done, or happen to be the aforementioned genius, might i suggest drilling a small hole in the thermostat to prevent vapor lock and replacing all those little hoses under the intake manifold. Some of those buggers are hard to find so order early. Cheers
