I have a 2018 Sierra 1500 with the 5.3L engine, bought it new, and now has about 38000 kms (23500 miles).

 

Here's a coolant filter install similar to a few other guys here, except I used a Luber-finer LWHB4861, instead of the more common cast-iron Wix 24019 

 

Parts:

- Luber-finer LWHB4861 filter mount

- Wix 24070 Coolant Filter

- 4 feet of 5/16" fuel line

- 2 brass 3/8'  90 degree elbow barbs

- thread sealant

- 2 worm clamps 

- 4 nuts & bolts

 

This was a pretty simple installation. First I installed the brass elbows with thread sealant, and attached the new "fuel line" hose to the IN port, with a worm clamp.

Then I marked and drilled 4 holes for the Luber-finer bracket, and mounted it with the 4 nuts and bolts.

I took the factory hose off of the thermostat housing and relocated it to the OUT port of the filter, and attached the new "fuel line" hose back over to the T-Stat housing. 

 

So the fluid comes out of the T-stat housing, through the new "fuel line" and into the RH side of the Luber-finer, through the massive filter, out the LH side, back into the factory hose and all the way across the front of the truck to the coolant reservoir. 

 

The Luber-finer mount came with the bracket. The black bracket says it's made in the USA, while the filter housing says China on it. Either way, it's pretty solid, quite heavy, and I think it looks good too.

Few more pics:

 

The thermostat housing after hose removed, I was surprised how small the hole is, slightly larger than a paperclip.

 

Filter install

 

I removed the drain plug from bottom passenger side of the radiator and drained roughly 1 gallon of coolant, it looked pretty good for 38,000 kms (23500 miles) since the truck was new. 

 

Inside of the drained reservoir, you can see some small bits of debris.

 

Inside the pipe leading to the water pump, you can see some small bits of debris and what looks like minor rust.

 

So of course it was very early in the life cycle of this coolant to drain it, but I wanted to see what things looked like inside, and I might as well have done it now while I'm already installing the coolant filter. There's definitely some debris in the system and hopefully this new filter setup will clean most of it out. I plan to change the filter once a year.

This was one of those things I wanted to do to mine but have never gotten around to doing. Thanks for sharing.

6 month update

 

Today I changed out the filter at 12,000 kms just to see what was going on.

 

Put a ziplock bag over the filter to catch any fluid, then cut open the cartridge to inspect the filter media. I could see some very fine / small particles between the folds, so it does appear to be working. Of course it's only a 2 year old truck, and a 6 month filter, so I wasn't expecting to find much. More peace of mind than anything. 

 

Will extend the next change to 2 years.

I had a good look in between the pleats, i could see some very small particles. Made me confident in the decision to install the filter.

 

Next time I'll try and unravel the entire length.

      Bench seat swap for 2021-2024 suburban

      By davester · Posted

      probably won't get a response from that user, as they haven't returned to the site since making that one post.  users don't (at least I don't, and I haven't seen any setting which would notify me via say, email) get any notification other than going to this site, and checking if they got a response on their thread...

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

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.
