New here looking for knowledge.  Have a 12 Chevy 2500 hd wt with a slight leak from the oil cooler lines. Had intended to just replace them when I did next oil change.  Went to parts store to get them and do it today and the 3 parts stores I went to none had the lines or could even look them up. I know these were common problems at least on older ones.  Anyone got any insight or a part number by chance?

We have a 2004  Express 3500 HD that had the oil cooler lines replaces Twice within a short period of time from dripping leaks up near the radiator .  Not a cheap repair.. The last time the Shop who worked on it Had some custom made at a Hydraulic hose company that specialize in  High pressure LINES..  

 

If you can find someone to do this you are probably better off then buying another factory set that will likely leak again. We park this van on very high end customer Driveways. We can NOT HAVE ON Drip of anything from under it..

Thanks for the numbers and idea.  I have access to a hose crimper may give this a shot.  Need to do trans cooler lines too.

When I punch in my vehicle info on Napa’s site it says doesn’t fit vehicle that’s what I was running into at parts store today.  What am I missing here?

I believe it will fit because the parts description says it fits up to 2013 Chevy 3500's with the 6.0.

 

The 2500 is the same frame, radiator, engine etc etc for the cooler line.

Kinda what I was thinking, just weird how I can’t find one listed for this model.  I know the part exists.

Does the front axle have to be dropped to get it through on these or can you fish it through?

Anyone know if this can be done without dropping front axle?  Txab it does appear this is the right part, unsure why all this places say it doesn’t fit.

Ended up cutting crimps off and replacing rubber line with 400 psi trans cooler line.  Where I screwed up was not paying attention to which line was supply and return. Anyone know if the top line off the block that mounts to engine is the top line going in radiator?

Thanks for the number but really need to know which line is which since I cut the factory rubber out and put in trans cooler line hose clamped in place.  Would it be the same as my 12 1500 with the 5.3?  On that one the top line running down side of block is bottom line on radiator.

      Very interesting thread. Definitely didn’t expect to see this kind of mileage out of that engine.

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By Grumpy Bear · Posted

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.
