Oil cooler line block bolt leak FIX!🚚🔧GMC Yukon ,Chevrolet Suburban, Escalade,2006-2014 Cheap Easy💲⌚

[@paulwalker5463]

You are the man! Very helpful. After a friend wanted to charge me 900$ to do the rear main seal when that was not the case. You saved me from getting screwed.

Same issue here. replaced the gasket and still dripping. Added UV dye to try and pinpoint the leak and it was the plug. Cut a 3/8" Allen to make the insert and when I went to install the hex, the plug turned. Mine was finger tight so no wonder why it was leaking. Instead of just tightening the plug, I pulled it. My plastic washer was in perfect condition. Cut it off, installed the O-ring and Teflon tape. NO LEAKS. Works like a champ. If you don't have a Harbor Freight near you as I do, Tractor Supply has a small bag of these exact O-rings in their hydraulic section that are rated for oils and such.

I went to my local harbor freight , follow all your steps and it work !

[@mbjdiy1778]

Fantastic !!! 😇

[@kvasir40]

. I had the exact same problem down to the leaking bolt and leaking gasket (2014 GMC yukon). Following the instructions provided in the video, I was able to successfully replace the cooler gasket, which was readily available at my auto parts store, and went to get the o-ring from Harbor-Freight as described. Out of curiosity, I asked my GM dealer, and quite interesting, they do not sell the o-ring (or the man was unable to located it or unwilling to sell it), besides, even if they did, probably the same cheap plastic one instead of an upgraded version as seen here. Thank you for sharing.

[@ازدشنوةالحجاز]

Watched this and several other videos on repairing the 5.3 oil cooler line block leak. In my case I have a 2010 Chevy Avalanche 4 wheel drive. I was able to move the front driveshaft out of the way after taking the U joint out of the yoke and pushing it back and then moving it to the side. Gave me enough room to use a 3/8 allen drive socket to remove the bolt. I removed the bolts holding the cooler line block first and then held the cooler line block in place with rubber tipped channel lock pliers. The bolt was not torqued very much and came right off. I cleaned the bolt and the hard plastic seal was cracked and came off in 3 pieces. My Avalanche has 125k and has lived its whole life in a hot dry climate. I used a new o-ring and a new GM oil cooler gasket. No leaks since and I was surprised how easy this was. Some of the really rusty vehicles I have seen here on KZbin would have made this job much more difficult. While I had the truck up I changed the leaking trans cooler lines too....NOT easy and if I do this in the future I am just going to cut off the leaking rubber lines and replace them with sections of rated rubber hose and high pressure clamps. Had to take the front bumper assembly almost off to reach the clips where the lines attach the cooler in front of the radiator. Thanks again for taking the time to make a video and detailed instructions.

[@alvarosilva957]

So you didn't have to make the tool just to buy the 3/8?

[@BacheFate]

Very helpful video. I ended up not needing to make the tool. I unbolted the oil cooler lines and put a block of wood between it and the oil pan. Of course, wrapped it with nylon to avoid any debris getting it those lines.

mine is 4wd and having an oil leak problem gonna change these things and see if it fixes it

[@6.2_vortec]

This is very helpful. Just did my oil pan gasket and the gasket for that oil cooler block and discovered the same piece is leaking, luckily mine is 2wd so I don’t have to worry with a driveshaft.

The hex plug on my 2007 3500HD has a plastic tapered seal with a break in it. It’s not a soft rubber o ring. I can’t find a replacement so I used rtv sealant with the old seal and screwed it back in. I’ll know in a few days if it worked.

cool and best of luck😇👉 in the video and description box you can get a box of nitrile o rings at harbour freight for cheap.www.harborfreight.com/225-piece-nitrile-o-ring-assortment-67677.html

Hi ladd, great video, but I have a 2010 Yukon xl and have to change the whole line. I do have oil all around the oil pan . I know the cooler line is leaking, and I already did the oil pump, pick up tube O ring and oil pressure sensor and filter. After about ten mins of running oil pressure drops from 40 to almost zero. I just wanted to change the cooler to see if it’s a leak in it causing the oil pressure drop. I still should prob do the pan gasket but do not want to take all this stuff down to drop the pan. Possibly the oil bipass valve in the pan that goes bad on these LS engines too. But I can’t snake the old cooler out, let alone what looks like a night mare to snake the new one in. Is there a way to snake this cooler out? Thank you so much, Kevin NJ

[@mbjdiy1778]

Here's the bad news you have to lift the engine up 1 to 2 inches motor mounts and whatever else disconnected , remove steering assembly and possible headers (my 2012 has to be done this way) = take it to a dealer or a qualified automotive repair shop if you have to replace the whole line... 😇God bless 👀👉IF NOT WATCH VIDEOS BELOW👇 👉Video's how to do:::: 👀 How To: Replace Oil Cooler Lines, 2007 - 2013 Chevrolet Silverado or GMC Sierra (4x4) the EASY way kzbin.info/www/bejne/nGSrnGtun56ghrM Oil Cooler Line Replacement 09-13 GM Trucks kzbin.info/www/bejne/amTRkmZ6oMaiiZY

[@kevinfraser640]

Ugh, thank you. As it seems, I have an oil pan gasket leak in addition and have serious questions about this bypass valve inside the oil pan. At 240,000 miles and losing oil pressure still after doing everything else. I gonna have to take the axil off and cross members and away bay along prob with the rack and pinion to get the oil pan down. So I assume at that point I’ll be able to put the new oil cooler in. It’s been a hell of a war forest gump. Geez I’ll hit ya back if I get there! Cheers 🍻 Kevin

[@TheBucktowncrazy]

First, great video Hope the arm healed up well. Maybe it's my bad eyes, but it looked like you are missing a bolt on the transmission pan. I noticed it when you first pointed things out with the pencil. Did everything work out with no more leaks?? Thanks for the video!!

[@mbjdiy1778]

🪔🛢4/24/2024 Still no leaks .... not a single drop ... 👀checked the pan ... bolts all there .... I am severely scared from that burn on my arm it was ... 3rd degree burn ... I probably should have gone to the urgent care ..... but all healed know😇

[@americanpatriot2999]

My 2013 Suburban LTZ is leaking as well. There is so much oil that I can't tell if its the gasket or that plug.

[@mbjdiy1778]

Clean it ... then run it ... find it

[@semperparatus3188]

The key bolt on the side of the block was spraying oil out of mine tonight. Mobile mechanic came out, it was a little loose, he tightened it and seems to have stopped the leak.

[@mbjdiy1778]

Good luck may just stop the leak .... unless plastic seal (plastic oring ) inside is cracked 😇

[@semperparatus3188]

@@mbjdiy1778 ive had it idling and so far its dry, but we’ll see how it goes. It was dripping and creating a puddle underneath when idling, it lost a full quart of oil out of it. He said it was loose about a turn and a half and ever since then, its been rather dry.

[@jamesethan3749]

What if my car just has a cap there, and no oil lines going to it? Idk how the hell my car cools the oil but on the motor by the oil filter its just a cap bolted there to cover it.

[@mbjdiy1778]

you do not have a oil cooler if it is capped off

[@vikingroverland7562]

Does anyone know what that does? Is there a valve in there?

[@andrewhamons962]

The only thing I find odd about this is that the plug uses a 3/8 inch Allen key I thought everything on these vehicles used metric fasteners.

[@mbjdiy1778]

that what fits or locking pliers around the body of the bolt 😇

[@andrewhamons962]

I just did mine last night and it is a 3/8. I am assuming it is just a standard machining plug.

[@Airman..]

This is not a normal hex bolt. This is the oil cooler bypass valve access

[@mbjdiy1778]

and it leaks ... poor design 😇

[@mikedavis5410]

My question is why not just take the line off the block and then takw the bolt out. No need to cut a hex down

[@mbjdiy1778]

Either way😇 but the GM rule of thumb (Ford Also) fix the one do not case the many or another... and if you do disconnect line follow my video in the link in the description for that gasket replacement fix

Those are not 10 minutes or bolts or 11 mm bolts for that matter. The heads are 10 mm and 11 mm in size I'm not the bolts But not the bolts themselves.

When you go to buy the bolts or use a tool they are called 10 mm 11mm bolts because of the head the threads are a whole other thing and length is another.............😇
