Start at battery connections. Load test batteries. If you haven’t replaced the crappy side mount cables for top mount yet, check the little puck that connects battery cables to each other. Check connections at starter and ground cable.

Make sure they are an AC Delco AUTHORIZED DISTRIBUTOR. There is a ton of chinese knock off stuff and holding fake next to the real ones you can’t tell a difference in the part or the packaging. The best version of the stock style pump is AC Delco EP158. It will barely hit specs and usually...

If your a/c doesn’t blow as cold as you want then absolutely get the trans cooler behind it.

Yuppers. Get it red hot a couple inches past the bend in each direction then dunk in water to cool it superfast. This makes it hard and not bend as easily… or as I called it earlier unbend.

Welcome

My name is Will, get ready to drink from the firehose… I can’t remember how to tell which is which- just know to VERY CAREFULLY start to thread them in incase it is wrong. None of the 6.2 had a turbo factory, the 6.5 also started without a turbo- later they are added but were always...

On the handles and rods for opening the doors: We kept the handles in stock in the fleet. Diagnosed properly: the rod unbends itself. Then the handle maxes out. The common action is people pull the handle with fingers and that elbow gets used as a fulcrum to lever the door open. Quickly comes...

At 277hp/460 torque, and the timing maintenance issue - it would have to have some serious mpg to be worth it. In the smaller pickups they net 25 mpg, so in a burb. I would expect 22-23mpg. At my work we have a couple dozen now, and I been tracking with the guys who drive them daily. The ones...

Preference. Diesel engine, most say last year not DEF fluid. Gas engines, most say just before cylinder cancellation. I fit in with those opinions. On the gas, I am in love with the 6.0. Most go to the 6.2. Near bulletproof engine that gives good mpg and can tow well. If a person tows more...

Looking for a pic to help a guy, I stumbled on this video. Anyone interested in dual alternators ought to pull all the part numbers off this video and save them. It might be a good idea if someone writes them down and posts them here somewhere in case the video gets taken down.

At some point the chain in the transfer case will need replacing. Rebuilding the transfer case isn’t hard or expensive. How many miles on the 2500?

100% That 2500 hd with the 454 & 4l80e is gonna put you WAY AHEAD in towing. It will drink more gas. But it will survive towing, and do it far more safely. I say get it, drive and wait to see what breaks down before starting to dump money into it. There are things that will make it better...

If the price feels bad- just look up what a quality set costs for a duramax. One injector alone is more than the whole set from Leroy.

Do a search for fireproof black foam. Make sure you pick one that withstands direct contact heat of 300°. It won’t catch fire but can melt if not rated for the high heat it will come in contact with.

I don’t want to make it sound like it can’t do it. But understand you are taking a rig that when brand new, you would be maxing it out. That would shorten the life of any rig. Now you are trying to do it on one with 30 years and all we can guess is a quarter million miles on it…

Well, sending a set of old injectors that are most likely worn out means they need s full rebuild, not just pressure adjustment. So they will need new pintles bought for them then the adjustment. So it is almost same cost as just buying new ones then having them adjusted. You probably stand...

The 1500 w/ 5.7 - check your door sticker because you are pushing the max capacity with it. Capacity changes with transmission and even gear ratio and depending what you have you might max it there If you are going to tow that much just a couple times a year and not through mountains on the...

Are you adding a car lift at some point?

Welcome. No, lack of a proper lift pump will ruin the ds4 or db2 much sooner. Some permanent changes are suggested to solve the issue now & for future. You have a ds4 ip (injection pump). Out the front of the ip is a 1/4” fuel line in an upside down U shape. Replace it with clear line. You...

Wish I knew something about the ally trans to help. All I know is they take a beating and live forever. Might need to find a specialized forum since they don’t fail all that often.
