Edit: So now that the temperature is closer to -20 than -30, there is no more coolant splashup happening. Seems to be something that only happens in extreme cold and something that iirc sort of happened last winter as well. My oil cooler lines hose clamps were slightly loose so i tightened those down as well

Coolant leak from somewhere, can't figure out where. I think I did a poor application of silicone when I installed my new water pump and it may be leaking now. Anyone whose dealt with a water pump leak on a 3.2 does it splash and spray up all over the engine bay from the fan or just drip out the bottom? It seems to be leaking intermittently and not when pressurized , this morning the engine bay looked like itd had a bottle of mountain dew exploded in it but after cleaning up the mess, getting it hot again and driving it for longer there was no coolant splashup. Spend a good 30 mins looking everywhere so see if I can find the source of the leak, and the only place that coolant is forming new drips (very slowly) after I wipe them off is the front lip of the oil pan thats under the timing covers

  2. Replace the alternator with Denso OEM reman unit

  3. Replace battery cables with new 6 or 4 gauge cable

  4. Wire brush and dielectric grease all grounding points

  5. Passenger side front end service 2.0:
    • Lower ball joint replace with OEM (AcDelco 'advantage" ball joint boots ripped after 1 year)
    • Address the source of the occasional 4wd whine from steering knuckle - likely knuckle bearing going out due to damaged knuckle seal!
    • Replace the knuckle seal with OEM
    • Replace knuckle bearing/thrust washer
    • Replace wheel bearings and races
    • Replace CV axle with a re-booted junkyard OEM axle, using the OEM outer+inner boot kit (replacement req'd to install manual hubs due to destroyed large circlip groove)

  6. Install the new manual hubs

  7. Replace the thermostat with new OEM as preventive maintenance

  8. Door latch: rear left door latch does not work from the inside. Linkage disconnected somewhere?

  9. Lock actuator: rear left door lock actuator does not raise or lower with the other 4 doors. Broken solenoid, or just a snapped linkage?

  10. Brake band adjust: a transmission maintenance item that I have not done yet. Will be performed alongside another filter change and drain and fill. May need to take the exhaust down for this one

on the non-working door lock, its most likely a broken door lock actuator motor arm...complete replacement of door lock module will be required....good luck on finding a good used one....
i replaced 2 failed rear door lock actuators, with $20 units from princess auto- can be had for $ 12 on sale....a few extra mounting holes drilled, custom bent linkage, wiring and done! power door locks fixed ! 8)

and thats a pretty impressive list of parts for good repair job :D !
will drive these until they quit and move onto something else.
parts from JERRY LEMOND.

Thanks! I will certainly give that a try. I'm glad I didn't get the OEM actuator, $250 :shock:

Paid for an hour of diagnostics at a shop that has done some great diagnostic work on my moms 4runner before. They said that the cooling system held pressure for a full hour, but there is coolant residue below the timing cover so they suspect a water pump leak is occurring only in extreme cold.
I really wish I had ordered one of the mahle/felpro water pump gaskets which are beaded, rather than using the crappy paper one that came with the ACDelco water pump.

As for the squealing noise in 4wd, they said they couldn't really hear anything, but it is definitely still making the noise. So idk, still guessing it's the knuckle bearing but I guess we'll see when I have it all apart this summer.

Half my rockauto order including the alternator has been stuck in a Memphis FedEx warehouse for about 5 days now. Southern US has bigger problms than courier services right now, so ill just be patient for the weather to clear up!
Also ordered 4x Continental ExtremeContact DWS06 - P245/40R19 for my Honda accord as the original Michelin 19" tires are at the Treadwear markers now

Left the trooper idling for 10 minutes with the heater off, and when I came back the temp gauge was the nearest to red ive ever seen it.

I felt the thermostat housing, and the area in front of the thermostat (rad side) was lukewarm, while the area behind the thermostat (engine side) was burning hot. My new OEM thermostat won't be here for a couple months, so I will grab one from lordco to use short term as well as bleed the system in case the guys who did the pressure test left an air bubble in there

Updates on the running "hot" issue:

Tested the thermostat in a pot of hot water, using two thermometers for accuracy. The original OEM thermstat opened both sooner and wider than the new aftermarket. Reinstalled the old tstat

Bled the cooling system of air on a steep uphill, and confirmed that the 1.5 year-old fan clutch is still operating perfectly well

Next, bought an infrared temp gun and measured it while the temp gauge was showing above 2/3 (this is as hot as I could get it today, other times it has come 3/4 up the gauge or more when the heater is left off):
Image

Temperature of tstat housing "before" the thermostat: 67F
Image


Temperature of stat housing "after" the thermostat: 132F
Image


Coolant outlet pipe 176.5F:
Image


Heater lines, heater core closed: 198F:
Image

Not pictured - Front of engine block and oil filter: 180F, Transmission pan: 105F


These infrared temps show an engine which is perfectly within operating temps and a thermostat mostly shut... while the gauge indicates an engine which is exceeding its cooling capacity and thermostat ideally open
So why would the gauge just recently begin hitting these highs that it never used to, all last summer with the heater off and the ac on and running the same temp sender that I am now, it always stayed in its normal position, just a tad under the middle.....

Is the new temp sender (Standard Motor Products premium line) gone failty and showing it as hotter than it actually is?
Water pump, radiator, fan clutch are all less than 2 years old and less than 15000 miles
Maybe I should remove the thermostat temporarily and re-measure temps?
Curious if the heater lines should be ~20 degrees hotter than the main engine outlet to the rad as shown? Perhaps while the hcore and tstat are closed those heater lines do actually indicate the "real" temp, and the sender is correct in its reading
:? :?

So, almost certain now that this is due to the coolant temp sensor having changed its sensitivity somehow. Drove her hard today then let her idle with the heater off to see how high I could get the temp gauge. Eventually, I was able to get it to creep up near red again (definitely not on the red, just much closer than I'm used to seeing it). Got out the infrared temp gun, and everything was at a perfect operating temp - coolant outlet 185F, before thermostat 100F, after thermostat 170F, oil filter 200F, engine block 205F.

I am 100% certain tippy is not overheating, and she's not even running hot. Must be the temp sensor giving me the runaround. Anyone else dealt with an issue like this where the "calibration" of the temp gauge seems to have changed? Because I now have a temp gauge that is riding well past the middle when the engine is at normal operating temp

Just out of curiosity, also scanned the temps of several other things today after a good hour long highway run. Immediately after stopping, checked the diff pumpkin which was at 100F. Transfer case was 183F.
Then, checked transmission fluid temps. Outlet line = 145F, after the oil-to-air cooler w/ pusher fan running = 80F, return line after radiator heat exchanger = 120F, pan = 100F (temps all measured on clean metal)
Hubs had a difference in temps, with the left side around 80F and the right at 70F.
Ambient temps today were 6C/43F

Got the ARB bumper and heavy duty torsion bars installed! Apparently this was the last one available in the entire world (shipped in from Florida), so hopefully ARB makes another batch. What a great looking mod, totally changed the appearance of Tippy. The amber lights in the bumper were wired to the fog light harness

Image

Also yesterday I replaced the front sway bar bushings with some polyurethane ones from suberian bushing, wrapped the bar the thickest PTFE tape I could find (the yellow gas line rated stuff) as a permanent lubricant to prevent squeaks, then a bit of silicone grease and we're set

the body roll has been hugely reduced by the HD torsion bars and poly sway bar bushings. I can take turns way faster now than I would have ever dared to before. With the extra weight of the bumper, these tbars provide almost exactly the suspension firmness I like.


My to-do list just keeps getting larger! In addition to the previous list, I will now be doing the following:




-Front differential drop: Will buy the brackets from Roberto on Isuzu Trader, probably will do a 1.5" drop. I leveled the front with the rear when installing the new tbars, I love the lift but I don't like the angles that the CV boots are at. 

-Oil pan gasket: it doesn't really leak, but since I can get the oil pan off easy when the crossmember, diff and steering idler are all removed, I will iust check for debris in the oil pickup and put a new gasket in.

-inner axle shaft bearings and seals: since I will be removing the front differential to install the drop brackets, I will also replace these bearings, as they are another potential cause of the whining noise when in 4wd

-upper control arm bushings: might not do these if the bushings are still in good condition

-Both sets of CV boots: since I will have easy access to replace the boots on both axles during the diff drop, I will be ordering another OEM inner and outer boot kit so I can have all new rubber on both axles.

-Dual piston front caliper upgrade and steel braided brake line install: I received my new Chevrolet Colorado calipers, they are Isuzus updated caliper design that bolts right up to 2nd gen troopers with only trimming the dust shield and possibly longer mount bolts as the only mods needed to install them

-Redo the water pump gasket it is still sometimes randomly dripping coolant out from behind the timing covers when shut off. I blame myself for using a non-beaded gasket and for a crappy silicone application. Its a very minimal leak and never drips when running, but I'll still need to fix it.  Even though there's only 12000 miles on the pump and belt, I may just replace them both again since they're both coming off

-Camshaft seals and end plugs: since Ill be doing the timing belt a second time in 2 years I will have no excuse to not replace these seals and plugs. No major leaks but they all seep a little bit.



Hopefully I can take care of some of these to-do items before the list grows even larger.

In other news, the first of two OEM parts shipments arrived! Amayama.com is definitely legit and I feel lucky that Isuzu is even still making/selling parts for these. The OEM CV boot kits are made by NSK and come with grease, boot clamps, snap rings and of course the boots themselves.

Where are you sourcing the parts for the dual piston calipers? Just whatever auto parts store? Rock Auto doesn't ship to me. What years from the Colorado do you get the calipers from?

I got mine from rockauto but actually NAPA may have new ones a well. Thry are for a 2004-2008 Chevrolet Colorado. You'll also need the front pads for the same application. Lots of remanufactured options, but I could only one new set avail, which is RAYBESTOS FRC11704N and FRC11703N

I got mine from rockauto but actually NAPA may have new ones a well. Thry are for a 2004-2008 Chevrolet Colorado. You'll also need the front pads for the same application. Lots of remanufactured options, but I could only one new set avail, which is RAYBESTOS FRC11704N and FRC11703N


Thanks. The discs are the same?

the one pic of your temp gauge is about where both my troopers run for temps....
good cross-over for the front calipers....good used ones are hard to find, i 've had two remans go leaky on me...
i bought an ebay set of drilled / slotted rotors and ceramic pads front /rear ...this trooper stops really well.

and thanks for the tip on the injector guy ....brenda runs smoother, easier on fuel... :D
will drive these until they quit and move onto something else.

That is some VERY interesting info on the 2005 Colorado dual-piston calipers; it means that for anyone doing the "Big Brake" upgrade to a Gen-I Trooper, they could use the 2-piston caliper as well. WOO HOO! Should be a drastic improvement over the stock Gen-II single-piston caliper.

Any changes required to the brake hoses? That's about the only thing I can think of. Trimming dust shields sounds Easy Peasy, break out the Dremel and a cutting disk!

I guess it might be time to put a Big Brake Upgrade Upgrade" on my list of things to do to my 3.4 LS. I already have Gen-II calipers and larger-diameter drilled and slotted rotors in the front and the stopping power is excellent.

Thanks for that great tip, maybe you could do a separate posting on that, and the Mods could make it a "sticky".............ed

That is bloody cool! You wouldn't think 2004-2008 brake calipers would fit on a car that old.

Then again, Isuzu has not changed the design of the front wheel hubs since the gen 1 trooper. even in a brand new D-max, you still have that silly arrangement where you need to undo the wheel bearings to change a rotor... :evil:

Wouldn't be surprised if they haven't changed their brackets, either.

Either way, i know what I'LL be doing on my next brake job! >:)
Should we sticky this thread to keep this information around?

Lots of interest in the brake upgrade it seems! I got the idea from a couple posts on the Isuzu Trader Facebook group from people who had successfully installed them on their 2g trooper.
I'll be sure to make a separate thread with plenty of photos and a proper writeup for the Colorado caliper swap, once I have it completed. I'll leave a link to the thread here as well once I submit it. Thanks for checking out my thread guys!

I was already planning on doing this, then I hit a dog today and felt like there could definitely be more stopping power. On my way back, I just laid on the brakes on the street and it was a pretty poor performance. This is on the soon-ish list now for sure.

Dog is fine, by the way. I came to a stop at the same time as I made contact. Then he trotted out from in front of me like nothing happened.

Update on the Chevrolet Colorado dual caliper brake upgrade:

Another part that you will need to buy in order to fit the Colorado calipers on 2nd gen troopers is the brake line banjo bolt.
Just confirmed, Dorman #13940 is the correct banjo bolt for the Colorado calipers (the earlier Isuzu calipers have a fine thread that doesn't fit their later caliper design)
The mount bolts are also different and are GM # 11609768 (but probably easier and cheaper to just find the correct bolts at a fastener supply store)

Good Info!

Dorman 13940 Banjo Bolt, $3.18 each at Amazon: https://www.amazon.com/Dorman-Help-1394 ... B000C5G2Q4

11609768 bolt, cheapest I found was on eBay ($7.09 each shipped):

https://www.ebay.com/sch/i.html?_from=R ... 8&_sacat=0

If the local GM Dlr has the bolt in stock, the list price is around $5.28 each.

If you find out the size of the bolt, let us know. A substitute bolt would have to be high-strength, to be safely used as a caliper bolt.

McMaster-Carr would be a good place to look, once we know what to look for.

Making good progress on Tippy! The water pump gasket was definitely the cause of the coolant drip. The ACdelco water pump itself is still perfectly good after 20,000 km but im putting a new Gates pump in anyway. Tomorrow I'll start pulling the front main seals and cam plugs. Took nearly a full bottle of superclean to get the block degreased! Also dropped off my power steering pump at Hydra Steer to have a new seal kit and bearings installed.

Re: Colorado dual-piston calipers and brake lines; for those of us who won't be running custom braided lines, which stock lines would work on a Gen I Trooper? Gen I, Gen II, something else? Does the Colorado-spec banjo bolt fit the stock ZuZu brake lines?

IIRC the original "Big Brake Mod using Gen II calipers required use of Rodeo brake lines due to the connection angles.
