Sorry, I saw they had a box and I put in the link. I don’t have a 2wd and don’t know if they are the same box.

That is a problem for all of us. Wear happens and rebuilds from auto parts stores are hit or miss. I had a worn out box like yours and couldn’t find anything I trusted to be better “rebuilt”. New like this : https://www.offroaddesign.com/gm-psc-steering-gears.html Just seemed too pricey. I...

Do all that was suggested above about the batteries. If you end up with 2 good fully charged and load tested batteries and still nothing at the switch. Check for power at the alternator and at the starter solenoid hidden behind the air filter housing. If you have 24 volts there, then go to the...

Looking under the truck should be your next step. Engine, transmission with a bolted on transfer case. Then drive shafts to the rear and front. If there is another box bolted to the rear of the transfer case. Then you could have something like a GearVendors over drive unit on the rear drive...

The brake light signal goes through the blinker wiring between the brake light switch and the brake lights. Here is a video about how to check the flasher box:

The transmission cooler before, after or independent of the radiator is a ball of worms this thread doesn’t need to touch. I put my oil on the drivers side and the external transmission cooler on the passenger side. I probably should have run the transmission lines to the passenger side of the...

Yes, drivers side with an extra transmission cooler that still goes through the radiator on the passenger side. Here is a video I did a few months ago about making new braided stainless hoses:

GM made the oil cooler separate on all of the GMT 400 trucks. That made me think it would be ok to do the same on my 6.5 Banks turbo GEP engine when I built up a Suburban to put it in. That was 7 years and 34,000 miles ago. I also installed an oil temperature gauge. I used a 1995 6.5 turbo...

The gasket between the compressor and the bracket/mount. Sorry I didn’t make that obvious.

Probably the -34P TM. There is a gasket between the bottom of the compressor and the mount. I was helping someone recover a truck 700 miles away years ago. It had a bad starter that we didn’t want to use again after the initial start. After about an hour on the road we noticed a little oil on...

I’m confused by your description. I got the new glow plugs part. When you turn on the key the glow plug relay clicks, the glow light comes on but stays on more than 25-30 seconds? At some point the light turns off and the truck starts right up then, correct? Are you pushing the throttle...

Something to keep in mind is that the 6.2 diesel cooling system has around 4 gallons or 16 quarts of coolant in it. The stock thermostat is a 195° unit which starts to open at 192° and is fully open with full flow at 203°. The original post stated that there was a temperature gauge installed at...

That is the story as I know it as well.

Glad to read that all is well.

There is no engine performance difference that I am aware of between the different CDR cans. The valve cover mounted one is just easier plumbing with the turbo. I used a valve cover CDR and plumbed it to the vent at the oil fill and at the air filter. While keeping the non CDR valve covers.

Depending on tires a M35 pintle hitch will be 32 (9.00)-34(11.00) inches above the ground. As others suggested don’t drive a military truck to get your CDL. Dozens of post over the years to search for about how that rarely ends well.

The truck has no clue what the voltage draw is. There is also no mechanism to increase voltage besides your right foot And the cold fast idle solenoid. The truck has 2 separate 12 volt systems. They join for starting, military radios, slave starting and the stock glow plug system. Otherwise...

Power goes from the headlight switch to the dimmer switch to the firewall plug and then to the headlights. If you aren’t getting the hi beam indicator then that means power isn’t getting to or through the switch at the base of the steering column. Check power there.

You can still run the engine without the intake manifold. The turbo can just spin by itself with no harm done.

Like anything mass produced. The 6.2 was made to work in all environments and a huge range of conditions. Also like all things mass produced there is a range of acceptable sizes and performance of many different components. As long as each part was within “tolerance”, it was ok to install it...
