Here's Why MY OIL COOLER LINES FAILED!! Is My Engine Smoked??

Here's Why MY OIL COOLER LINES FAILED!! Is My Engine Smoked??
In this video I find my engine oil cooler lines are leaking again. I just had these replaced roughly 4 years ago. I figured something as detrimental to a motor as this would last longer than 4 years... I decided, because it was all that was available, to get the Dorman product and see how long they'd last me. The new lines looked great and installed just fine but I did have a problem with the old cooler line connectors. Wish I would've had the foresight to get the new connectors in the first place but at least I was able to capture it all on video and hopefully help a few of you out there!

I have been in the auto repair industry almost 40 years now and when people mention OEM my comment is yes OVER EMPHASIS MARKUP for sub standard parts ? Just because it's a OEM part does NOT mean it is a high standard remember the parts are usually subcontracted to third parties to manufacture, so occasionally cost bidding wars mean they only meet manufactures specification NOT the highest quality. Dog eat Dog profit society My recommendation is After market custom made hoses and fittings made a a hose supply vendor and upgrade the fittings to Military or Industrial grade. You may pay the same as OEM price but typically it will be a saving over OEM but more comparable to jobber wholesale price. FYI the only part a manufacture makes and spends Billions on is the Owners Manual for the vehicle and Sales related Items that are printed externally ... But the owners manual is the most expensive manufactured part for any vehicle ( Information supplied by Toyota Motor Corporation ) Never let the word OEM be a factor for purchase ? Let the words highest Quality be the determining situation if the OEM failed repeatedly why continual to support there pocket and lower your integrity for high standard. Great video and yes ALL manufactures do have some great parts they are NOT all cheap. Great video again you have a great presents and showing educational way to your videos.

@@chetmyers7041 : Just buy them from the dealership. For my old 2006 Tacoma I did the stupid mistake to buy the headlight online for about $70 apiece. I knew they are aftermarket parts made in Taiwan, but I thought what the heck anybody can make some decent headlights. I installed them both, and after a couple of weeks we had a serious thunderstorm with a lot of rain. The headlight on the passenger side got filled with water and the bulb exploded. Ok.. got one from a Toyota dealership for $220 or so, took me 30 min to replace it (simple truck, really...). After one year it works and looks great. But the crappy Taiwan-made headlight on the driver side is now foggy on the inside, and started to peel off on the outside. Now I'll need to spend another couple of bucks....

[@kcscustom9759]

Nice video! I think you will have good luck, doorman makes some pretty good quality parts. Don’t see too many factory engine oil coolers anymore. I actually added one to my 03 Silverado 5.3 though because I do a lot of towing and hauling. I upgraded to a larger radiator with ports for both transmission fluid cooling and engine oil cooling. As well as I also have an individual external cooler for each, that the fluid passes through after going through the radiator and before going back to where it came from either the engine or transmission. This setup really keeps my temps down I love it. When I installed it originally though I did have to replace all of the line fittings like the two you had to replace. Most of them looked absolutely perfect so I tried reusing them at first but that was a no go, half of them started leaking so I just replaced all of them so I wouldn’t have to deal with it later.

Around 13 years ago my 97 Ram 1500 started leaking at the same points. I cut the lines off at the metal using a metal bit on my multi tool. Flared the ends of the metal with a brake flare kit. Then used some hose and hose clamps I bought at AutoZone. Still not leaking 13 years later. Edit: ram has 389k miles on it. It gets used a LOT.

[@Austinole11]

I deleted the entire oil cooler system in my 97 5.7. I replaced it with standard SBC oil filter adapter and eliminated the lines and filter housing. A short PF454 filter provides enough clearance so that the front drive shaft doesn't make contact with it. I am glad I did it.

Toyota and Lexus have a similar problem with their rubber hoses failing and leaking. They redesigned their oil cooler lines to an all metal lines . I just had mine replaced yesterday under warranty. It’s not a recall , just a technical service bulletin. Which means they only replace them if they are leaking. You should look into having steel braided hoses made up for your vehicle.

[@cwhitm4]

@1Road if they fail again, slice the factory crimps off with a dremel to expose the barb connector on the metal tube. Reattach the hose with ear clips. (Oetiker or similar) Use 3 clips per connection and it won’t fail again. You’ll need the special crimp pliers to install them.

[@michaeldose2041]

Thanks for the tip. I found the double crimp to pretty much last the life of the hose, but I guess this guy didn't. I just replaced a set of these lines off a 1999 Tahoe.

It's a little unnerving to see them fail that quickly, if I find myself in that situation I will definitely use your idea, thanks.

Good luck with those quick connect fittings. Little plastic tabs hold those lines in. They love to break, blow the pipe out and wala you have no oil pressure and a bad engine. Replace them with the updated connector used for 96+ 5.7 vortec engines. Has a metal clip to also hold the line in. Another option is getting rid of that quick connect mess altogether and going with a flare fitting.

Hi Dillon can you post a link where I can get the 96+ 5.7 with a metal clip?

[@bmeggs19]

That middle space, between the crimp points in the center of the fitting on the end of the hose, is bubbled out farther than the other inbetween spaces between crimp points. Since ive done that several times where I work, i can tell you why it happens. When the fitting is crimped, its not seated correctly in the crimping machine. Ive just noticed this on my 94 k1500 and those cooler fittings look like they werent crimped correctly also. I might try to stick braided hose in there and make my own hoses.

[@jf4872]

Use a small mirror to view into the fitting and fish the o ring out. The place the new o-ring on the plastic tab seated prior to install. Smear with oil prior.

[@RetroPCUser]

That Suburban is looking real nice. Does it have the rear windshield wiper as well? Oldest car I have is a 2001 Oldsmobile Intrigue and had a coolant leak, but I sourced it as the coolant recovery tank being the culprit (and I was right) and fixed it myself. Had to replace the coolant sensor as the cheap one in the new tank was defective (said low coolant but the tank was full hot) with the one from the old tank, swapped the O-ring gaskets, and the warning light went away, but it still does the self-,test when I turn the key to the on position. 120,200+ miles on it and running strong. Gotta fix the exhaust leak some more, replace a stud or two and the lug nuts, and fix the fuel gauge. I'll fix the ABS (hub assembly on the passenger side front is out of commission after 17 years (2018 is when it started to not work anymore), even live data showed the RF wheel was showing 0 MPH using the Autel MaxiAP AP200 Bluetooth scanner) after I get a new job as I'm unemployed.

I removed my oil cooler lines on mine as they would not stop leaking. And eventually I also removed the adapter. And I am now using a standard sbc oil filter. Obviously I need to use the short one.

[@seniorjohnl]

The 4.3L S10 uses similar lines but with quick connect fittings at the rad. They all fail at the metal to rubber crimp. I used Napa's house brand aka Dorman lines with lifetime warranty. They last about 1.5 years before leaking again, replaced both lines about 5x with free replacement over the years. Waited too long on the last set and one crimp failed completely at a drive-thru, pumped all the oil onto the ground and seized the engine. The GM lines have no warranty but last 3-4 times longer in my experience, been using those ever since. I don't know if I would have had a legal case against Dorman for the failure since it had been leaking for a while before letting go.

[@marklennox2151]

At least you were at a drive thru. My failure occurred on I95 going through Hartford, CT and my 4.3l Astro seized in the middle lane. Talk about stress.

[@samsquires2877]

I like oreilly auto parts. They seem to have decent stuff.

[@biff314]

They are not relatively the same ... notice @ 1:00 the old, previously replaced line shown, has two crimps which are slightly larger than the Dorman crimps @ 1:21 which have 3 crimps, which are a bit more narrow but provide a more effective crimp as the definition of those 3 narrower crimps are much more defined which should provide better sealing between the metal and the rubber. I am going on 5 years with my Doorman replacements and no leaks. Originals started leaking around 290k miles. AN fittings and braided hose as suggested by Groundhogz, will eliminate leaks long term.

[@dbfcrell8300]

I wrote to Dorman a few weeks ago just to tell them that it has recently come into my understanding that everytime I reluctantly "had" to buy one of their parts (due to no other choice available), the part was always as good, if not better, than the original part I was replacing. In fact, many of the Dorman parts that I've purchased over the years were obviously reengineered to fix the manufacturing problem with the OEM part, just like the multiple crimps on the hose you're changing out. I truly believe Dorman is one of those overlooked companies that saves a LOT of mechanic and DIYer's asses, and they don't get any credit for it because their parts are on the floor in a display, not behind the counter-where real men shop. Just sayin'.

[@LH-zn3jg]

And sometimes you get smoked using dorman parts. I bought a lower intake manifold for a gm 3800 that was absolute crap out of the box. My son-in-law bought a dorman turbo charger that crapped the bed after two weeks. For my money and big stuff, go OEM.

[@jaimeedwards1269]

I bought a 09 Sierra with 200k miles. I found the transmission cooler lines were leaking from the same area. After some research I learned this is very common. People have replace them only to have them leak after a few years. I removed the leaking lines cut the crimps off flared the ends of the lines and reinstalled them and ran TOC hose using band clamp to secure them. All it took was a couple hours a flaring tool, cut off wheel and $10 worth of hose.

Some Napa’s make hydraulic lines you could have them build you custom oil cooler lines they’ll last the lift of the truck and then some, a bit costly but totally worth the price, we’re talking double braided steel triple rubbered I might make a video on it for my 95 Tahoe if I do I’ll let you know

[@jhanlon1903]

can you romove the lines and fittings and use 3/8 plugs at the filter housing to discontinue the oil cooler, i have a 97 sierra 5.7 with 4wd and never tow anything

[@thecupoftruth3508]

Just purchased 95 4 x 2 suburban this is my fourth suburban this one has roughly hundred thousand on it one owner, and experiences with a 5.7 Vortex bottom knock and I feel that replacing the oil pump can give longevity to the motor. This one doesn’t have the knock just yet but do you feel it can only help?

[@jewllake]

I would have tried cutting off the crimp connector and removing it leaving the barb, then reinstall the hose with permetax and two worm gear clamps.

So when your temp fix fails and your oil all pumps out onto the ground while your tooling down the highway with your tunes cranked up you can buy a new motor? Don't get too clever with engine oil lines, the new ones aren't that expensive.

I've seen too many examples of problems with these gm oil lines. The quick connects can become brittle and the hose swage fitting remains a question mark to me. Are swages overcrimped, or is there a bad match between fitting and hose spec? I can't say - I'd have to see these at assembly time. Like most hydraulic fittings, there is an ID and an OD spec: if they don't match well, reliability issues lurk. Best bet? Get whatever adapter fittings may be needed for that filter housing, and run your own tubing and hose - the original parts suck. Keep ID the same or slightly larger, as in going from 3/8" to 12mm or some such. Keep hose location & length similar, as it serves to dampen vibrations/take away flex problems that would plague a purely hard piped system with insufficient offsets. Your o-ring blues... remind me of why I love swagelok so much: there are none!

[@MrCamsoup]

You’d think someone would’ve made some stainless braided hoses that thread right into the oil filter adapter, thusly eliminating the quick disconnect junk.

[@wolfeman6380]

Gawd dam watching this made me think, what if they Snapped off like the intake fittings, hope those are not cheap pot metal 😳

[@tsutl84]

How did you find the full lines? I can't find the full line anywhere! I have checked everywhere and they all have only the rubber line and one side of the metal line.

[@Rockxenez]

Nice

[@kevinpeters1533]

What do I do if mine is leaking from the part you screw the oil cooler line into on the radiator?? Is there anyway to fix that without replacing the inlet outlet tank/radiator?

[@danieltaylor2340]

Do you have a video on transmission cooler line replacement

[@PeteyG708]

How well are those Dorman hoses holding up?

[@DaveSomething]

mine snapped off in the transmission... I barely applied any pressure and SNAP! but it's a Dodge, so I expected it to fail.

[@x-man5056]

Righty-tighty, lefty-loosey?
