Moving a few comments from other threads:

 

 

 

Sounds like some good mods. Just curious but what are the benefits to a coolant filter? What contaminants build up that need to be filtered out? Especially with new vehicles. Being around vehicles with over 300k on them, some with the original hoses and possible coolant with no filter system on them and all is well. Not sure of the benefit of a filter but I'm not educated in this area. I would think a flush every 5 years would keep things clean enough seeing most don't bother and have no coolant system related issues.

 

 

 

The coolant filter should be the #2 mod to do on these trucks right after the catch can, dexcool has a nasty hobbit of turning to "gunk". I can't tell you how many times we have to rip apart gm cars here in my shop because of Dexcool clogging up the coolant system. Dexcool flush every 50k and the coolant filter and your motor will thank you in the long run

 

 

 

Just curious but do you have idea what the average mileage is on these vehicles that have clogged up coolant systems? I wonder if it the ones going past the 5yr 150k mile service. Coolant service is a forgotten item to most vehicle owners.

 

 

 

As originally stated, at 40k and 16 months I had "crud" growing in my overflow. Which got me off my arse to put this kit together. I plan on doing a coolant flush and fill around 60k. Which for me is about 2-2.5yrs.

To me it would seem that something was added to the coolant system that was not compatible to cause issues. With all the thousands of GM vehicles on the road running Dexicool, one would think there would be more issues than there are.

 

I'm not up 100% on Dexicool but was under the impression that the system is supposed to be a close off system to the atmosphere, if air can get in then that causes issue. So this would make sense that if these clogged, thickened systems where not sealed then it could cause issues. Not trying to start anything but maybe help prevent to have others check to make sure their system is sealed.

I just ordered this same setup via Amazon. Ran the same price, I'm excited to install!

Has everything worked out for those who installed already? Anything new?

Doing more and more research before I install. From what I found, the recommended coolant filter is designed to be used as a bypass filter. Not an inline filter like shown. It will slow down flow when in line, especially if the filter starts getting clogged. Inhibited flow could result in strain on the water pump also... so I'll be adding tees between the hoses that'll lead to the filter, and connect those tees together to ensure everything is flowing properly.

Fascinating I have never heard of a coolant filter before. The things you can learn on this forum are amazing. I like the idea but I think I will stick with my current plan and use a whole truck filtering kit. (When this one gets some miles on it and a few years old I will filter it back through the dealers lot LOL)

How will you be running your lines? I had a coolant bypass filter on my 6.0 superduty due to all of the casting sand that leaches from the block. Crazy how much sand was caught with the bypass. On that truck I tee'd into the heater core line and then another tee into the degas/ coolant reservoir line. Thanks in advance.

I took some pics and tried to depict my plan to be best of my ability haha. Waiting on the hose to come in the mail on Monday. My plan is very similar to the setups above.

First I'll remove this hose from the connections shown at the green arrows. I plan to keep the hose in case I ever decide to put it back.

This is how I plan on running the lines. Pink shows the coolant/heater hose. The yellow shows the brass tee connectors. I plan on teeing over some of the flow to relieve pressure. Putting all the water pressure through that filter without a relief could strain the pump. This way it should equalize out nicely.

By the way, the way the hoses are setup in y'alls pictures above are backwards. I tested, and the flow goes the other direction.

Flow comes out of the intake manifold and flows through the 5/16" small coolant hose into the overflow tank. That's engine -> overflow tank. I've removed the hose at the coolant tank and had the engine running to verify proper flow direction. Not sure what other folk did.....

That's right. So the hose from the engine should link to the upper hose barb on the filter. The lower hose barb is the outlet, and should be linked to the overflow tank.

I did more research and found that you are indeed right. The inlet is the lower barb.

      OIL CONSUMPTION

      By RSTRICK · Posted

      I have a 2024 Chevy Silverado 2500 with the 6.2 liter engine, Vin: 2GC4YME79R1273849, with 27,437 miles. Recently we took a trip from Candor, NY to Townsend, TN pulling our fifth wheel, when I got close to the Townsend, TN area The truck gave me a message of low oil. I checked the dip stick and found it was 2 quarts low. Today, August 27, 2026, I had the oil changed and the technician Found the truck was very low on oil.  Is there a Recall for this? What is my recourse for this issue? Do I call the dealer where I bought it or any chevy dealer?   Robert Strickland 292 Owego Road Candor, NY 13743 352-502-6588 [email protected]

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      That is the funnel kit I bought and for being here in Canada I did get a better deal than what other sources were charging through a certain supplier in town that sources more directly and they ordered it for me. There are other items now on the market which would be perfect as well but this has worked well which was the hope when I bought it. I mentioned the Amsoil quart bottles as they have that squarish shape up top and it props nicely on the rim of the opening without falling into the funnel so I can leave them sit and drip a bit. You may have already figured out that to get the cap off the valve cover unless one is 7 + feet tall its not going to be reached without standing on a step of some sort and so when I do that I put the right adapter in and just leave the elbow on the funnel all the time anyway and open the lid and then if using quart containers for sure I can stand beside the truck and leisurely add the oil, and I can leave that funnel on when starting the engine to let it idle to fill the filter and then add the rest of the oil to top it up before removing the funnel and putting the factory cap back on. I put the cap back on the top and slide the bottom cap on as it fits onto the elbow adapter also and then store the funnel in a clean household plastic garbage bag along with the adapter so I have no reason to be washing out the inside of the funnel as I keep it completely clean between uses.    Draining the oil as per the under the truck portion, yes indeed that is slick as someone was thinking on GM's part there and admittedly I don't drop the oil screaming hot in this truck due to the exhaust being there and makes it safer as far as the oil temp if its just warmed up some instead as I don't have the truck on any ramps etc as I do it as the tires sit on the garage floor. The filter is not boiling hot then either and can drop it off into another pail after pulling the drain plug and just leave it drip out. Go back under a few hours later with new filter in hand and clean off the filter base and put the new filter on and install the drain plug. The filter is a little cramped in there as per wrapping ones hand around the filter and I am so used to using the band style filter removal tool that its no big deal and same for snugging it up. My filter wrench is many years old now but I think this is the current version and sounds like the right size, just in case my explanation was not great ( those nylon strap wrenches that one tool fits all filters are not my favorite tool to use, I much prefer this style personally )     57020 Swivel Gripper - No Slip Filter Wrench - Small | Lisle Corporation   And again about the oil draining and filter setup under these GM trucks, I've watched Ford videos of them struggling with oil flying sideways out of the oil pan on the gas 7.3 due to the sideways drain plug onto other components or cross members and guys trying to make shields out of carboard etc and other Ford pickups that Ford insisted they have sideways drain plugs. One win for GM there anyway with this engine.

      Kind of off topic, wife drives a 2023 Yukon Denali with the 3.0, been a great rig so far, incredible fuel economy for a truck that big and heavy. Coming up on 50000 trouble free miles.

      Valvoline R&P Fuel System Cleaner

      By PunchT37 · Posted

      I`m gonna try some of this in my 2000 LM7 that has had the famous piston slap since 17,000 miles or so. I have used Mopar combustion chamber cleaner down the spark plug holes a few times in the past. Corrects the problem for a few months or so. Then returns. GM top engine cleaner has been used also. No good results from this.   This LM7 never used oil. Even running the piss out of it.   Course, I`m gonna use this in my 2025 L84 while it`s still clean. It`s got 13,000 miles. Used Chevron fuel system cleaner [2 bottles in tank] a tank or 2 ago.
