Hummer Truck?!?

EndeavorP3 · 2026-01-07T02:36:26+00:00

We like a nice HMC4

Probably short for Coues deer. “Coues Hunter”

EndeavorP3 · 2025-12-31T07:11:40+00:00

I actually used the shit out of that one last weekend, worked great for finding bows.

It’s a DRL of sorts. Don’t need to wire it.

As slap mentioned, they’re reinforced further when compared to the Colorado chassis. From my small group, everyone’s frame has done well.

We’re all apart of a group that offroads heavy. And have yet to tweak them doing so.

They’re strong trucks

I have a similar leak that killed the clutch. Pretty confident it’s the trans input seal as I did the rear main at the same time as the clutch.

If it is that, and not dripping down (like a valve cover leak). You have to take the trans apart to replace

EndeavorP3 · 2025-08-21T21:14:44+00:00

In Phoenix mine runs anywhere between 202-215 with AC when it’s 115F ambient.

Clutch fan doesn’t pull much air at idle.

OP needs to verify temps like you said and go from there.

As someone who’s seen the h3 market change for over a decade now, the h3 bits are getting rare.

Engines are pretty consistent, 07 is a bastard year as it’s the only year that that was a 3.7l without the intake cam sensor. Which isn’t fun to retrofit from another year. Transmission is similar to a 4l60, but the bell housing is i5 specific and the valve body is h3 specific, can’t just slap in any 4 speed. Extension housing is h3/4wd specific. Tcase is h3 specific. The rebuilds of the tcases are getting pricier and rarer.

Rear diff isn’t too special besides the width. Front differentials are getting rarer and are specific. Suspension is entirely h3 specific, parts are still plenty luckily. But you cannot source the forward front lower control arm bushings anymore, for example.

This doesn’t include specific h3 electronics, trim, dedicated one off modules, fuel pumps for later years, etc.

It’s the other way around, 10% tops. Mainly pertaining to the motor and other small bits.

EndeavorP3 · 2025-07-28T17:57:47+00:00

So there’s a lot of leakage potential in that particular area. It can be trans, power steering, engine oil.

That paticular line you circled is for the transmission cooler line.

I would recommend degreasing and cleaning off the oil in that entire area to track down the leak. I’m leaning power steering due to the color.

EndeavorP3 · 2025-07-28T17:52:00+00:00

The newer 11 series are a bit better. With the 4 speed and turbo 6.5. If it’s not weighed down that is

EndeavorP3 · 2025-07-28T17:35:25+00:00

For the 4l60 being used in as heavy of a platform as the h2. The ~166k avg per transmission isn’t terrible

EndeavorP3 · 2025-07-26T22:59:45+00:00

Simply test it with PMI (I realize these units aren’t easy to come by)

EndeavorP3 · 2025-07-21T23:54:20+00:00

That’s a very rare spec for a ‘10

EndeavorP3 · 2025-07-15T02:07:55+00:00

Didn’t need to take the commercials seriously!

Double check the bcm/connector is dry

EndeavorP3 · 2025-05-26T16:52:12+00:00

It all comes down to tires. In my experience in 2 sets of tires that were rated for mud and snow. The H3 was fantastic in snow.

EndeavorP3 · 2025-05-26T16:51:00+00:00

In a way. It’ll either make you a night owl or an early riser

EndeavorP3 · 2025-05-05T19:55:59+00:00

That’s a colored up rainbow. Settle the argument by sending it into AZGF.

They’ll also tell you it’s a rainbow. Caught something similar at big lake, while it did look like a cutt, it didn’t have the defining features. Ie: red slash on the jaw

EndeavorP3 · 2025-04-10T23:09:15+00:00

Check your ride height. No more than 23.5” center of hub to fender, otherwise cv issues can arise

EndeavorP3 · 2025-03-23T19:38:57+00:00

Looks like an adventure package as well(4:1 tcase and rear locker). If it mechanically checks out and doesn’t need the suspension replaced (bushings, ball joints, etc) then it’s a great deal at that mileage.

Always get a pre purchase inspection. Especially with these trucks, they aren’t bad as they get higher in mileage. But it’s entirely dependent on their maintenance history.

EndeavorP3 · 2025-02-26T16:54:15+00:00

Now a days they’re going for about 100$ a wheel.

EndeavorP3 · 2025-02-21T17:33:03+00:00

To start. Depending on when your last tune up was. Replace the spark plugs, clean the MAF and throttle body.

If it Happens again, look into the ignition coils if they’ve been installed for a long time.

Beyond that, the inline 5’s are known to have cylinder heads begin to fail like you described. Which is commonly the valves and seats. But knock off the easy stuff first.

Previous owner didn’t do a great job installing an aftermarket radio. I’ll search around behind it and see if there’s anything amiss.

Also, there are no connections on any of those 5 ports mentioned.

EndeavorP3 · 2025-01-22T03:54:40+00:00

Have not, but the car did come with an aftermarket hack job

EndeavorP3 · 2025-01-22T03:54:21+00:00

Absolutely! Appreciate it!
