Check out this site on the Diesel Place.

 

The Diesel Place

 

A technician at a GMC garage in Grand Rapids, MI wrote up these instructions. It is really very simple to do. There is one missed part in them. He indicated unplugging both the Water In Fuel sensor and the Fuel Heater. The Fuel Heater is incorporated in the filter head and does not need to be unplugged. You can see the wire on the top of the filter head; just follow it along under the filter and unplug only the other wire.

 

I am mechanically inclined, but patience, time and tools handicapped. I change my own oil and filters and rotate my own tires and that's it. Mr. Goodwrench at the Chevy garage handles the rest. I just changed my fuel filter about 2 weeks ago in about 25 minutes. That included the air condition line adjustment and running between two garages to round up the necessary tools. I'm sure I will be able to do it in less than 10 minutes next time.

 

BTW, the owners manual suggests changing the fuel filter at 15K miles, but dmaxalliTech recommends doing it at 10K mile intervals. It's an expensive engine and well worth making sure it is done in a timely manner.

There's no way I can pull my filter up through the top (without removing the battery & moving the cooling lines), so I just put the filter in a plastic baggie after removing, set it on the frame rail, bend the wheel liner a bit and pull it right out. Doesn't leak or spill fuel.

 

Then I put the new one in the same way. Quick & easy.

 

Just be sure not to get diesel fuel on ANYTHING.

I feel it's easiest on my '01 to just remove the 2nd battery. It only takes a couple of minutes and then it's very easy to get to everything on and around the fuel filter. Even with taking out the battery, the whole job only takes about 10-15 minutes.

MCourson - did you get to the Diesel Place link on the filter change? I sent it from work today at lunch. It seems to work here at home on my own computer too.

 

I'm not sure why anyone would want to fool around with removing a battery or a wheel liner. I admit, I was leary about adjusting the air conditioning line from the condensor, but it took quite a shove to get it to move about 3/8 of an inch, which was what I needed to get the filter between it (the a/c line) and the turbo intercooler line. This is a one time adjustment and is very easy to do.

I owned a 2002 Duramax and have helped my buddy change his fuel filter on his 2003 Duramax, and on both the best way I've found to remove the fuel filter was to pull the front right fender liner down. Simply pull out the plastic tabs that hold the liner in place, pull it down and you can see and have easy access to the fuel filter. It's a pain any way you do it but this seems to work the best....a major design flaw in my opinion as they could have place it in an easier spot.

thanks guys, i am registered also but could not get the page to come either. I cahnged it last night. Took about 35 minutes cause i dropped the o ring down into the engine compartment. Other than that i just removed the second battery and it was simple. Would have taken about 15 min if i would have not had to crawl up under and fish around foe the seal. Later yall

Do it like conrav. out the bottom in a ziplock. Its really easy that way. Took me about 10 min. that way. I was looking for a way to do it easy by the side of the road just in case of a bad load of fuel. I put the new filter in a ziplock till it gets screwed on to keep the dirt out.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
