I've never understood why all cars don't have a coolant filter. It just seems logical to have one.

Most heavy trucks have a coolant filter. Many of those coolant filters come with a tablet of conditioner in the bottom. If you shake a new filter, it will rattle. Also, be careful opening those coolant filters. Some brands have a really strong spring and can hurt you.

They do also contain additives like anti corrosion etc

Didn't know Burt kreischer knew how to work on cars.

And if you have conventional coolant it maintains the additives, so to speak

It'll definitely help keep the impeller in good shape in your water pump.

Diesel coolant filters add supplemental coolant additives aswell, they're for coating the exterior of the cylinders to prevent cavitation from vibrations.

im more impressed that you have a tool for opening filters

So if you plan on owning a vehicle longer than 10-15 years a coolant filters a good idea thanks 👍

I've been a mechanic for over 40 years. I have 5 large tool boxes full of tools. But never got one of those fancy filter cutters. 😂

It’s on the list for 17 6.7 powerstroke. I’m case anyone is wondering filtering sediment and scale out your cooking helps work more efficiently and keeps you from chewing up water pump bearings.

I own a larger truck with a Cat diesel. When I got the truck with only 9000 mi on it, the coolant looked disgusting. I flushed it and ran it at least 10 times and the coolant was still pretty gross. After installing Cat ELC coolant, I was disappointed to find that the coolant looked old and brown despite the number of flushes the block had just gotten. I installed a Cat coolant filter and ran it about 500 miles. After that, the brown coolant now looked red and transparent exactly like it came out of the jug. It was an absolute night and day difference. Highly recommended!

I need to get one. The guy i bought by car from used water in a cast iron block instead of antifreeze.

You'd think this would be unnecessary, since the coolant system is supposed to be a closed loop, especially if it was filled with quality Fleetguard coolant. Then again, as long as the filter doesn't obstruct the flow and make the water pump work harder, it's not bad insurance.

It's an issue with the 7.3 because of cavitation. I don't have one on my 5.9 Cummins. Stay safe 😎

If you got a look at one from a diesel that does over 100,000 miles a year, you’d see what it does. Also, if you’re running regular life coolant, the filter maintains the additive package for the coolant.

Sure they work. As long as your cooling system remains clean, you really don't need a filter.

Man the 7.3 was a real motor I would give just about anything to have one

Wish I had a can opener that was so effective :D

For applications that require supplemental coolant additives (SCA), some filters are available with different doses of additives inside. You would test the coolant, determine the dose needed, then install the corresponding filter with the correct dose.

20,000 miles in 3 years? Bro teleworks for sure

I don't have a diesel but I have a 99 GMC K2500 crew cab and been debating to install one, i believe these work honestly.

A coolent filter sounds inviting; however, there is no friction to protect. Its just not needed - it's like a filter for the coolent system.

I run one on my Peterbilt 379 with the 60 series Detroit. We change it every oil change. It seems to be helping with sediment.

6.0l powerstroke was known for having residual sand from casting show up. 7.3 wasn't too bad. Still doesn't hurt putting one on anything.

Power generation diesel technician here… coolant filter do not have the intention as the name applies, although they do filter because of their design. As a piston goes down on its power stroke in a diesel engine the piston in the cylinder is not a perfect fit. It rocks back and forth a tiny bit. This causes violent vibrations that transfer through the cylinder wall into the coolant jacket. The vibration causes a mini implosion causing the metal on the coolant jacket side of the cylinder wall to pull metal. Coolant filters coat the entirety of the cooling system with a layer of material so that these vibrations do not pull off metal causing a pin hole to go into your cylinders 🎉

Volvo uses coolant filters to dose the corrosion protection additives back into the cooling system that naturally gets used up as the coolant degrades.

Found my new can opener 😂

I added one to my 1987 IDI Ford diesel coolant system and OMG it caught all types of junk. Pretty much plugged up a coolant filter in about 600 miles. Second filter was much better. Mind you this was older coolant. Personally if you add one I'd do a full drain, water flush with distilled water then fill with clean coolant with new filter. Change filter after 1000 or so miles then go to longer change intervals.

“Do filters filter? Yes, filters filter.” 🤔 Okay, thanks. 😂

Bert Krieschers twin. Lmfao

This is slick, gonna have to get one fer my boat when eye giver er a heart transplant

Most of what it picks up could probably just be drained out with a partial coolant flush after any head or radiator maintenance.

MY Volvo D12 had those and after 1.5 million miles the block and head looked pretty good internally. I would typically change the coolant filter every 100k

My 99 Honda accord started leaking oil into the water jacket, I wonder what that would’ve done to the filter.

I thought the coolant filter was the radiator

The other thing they do is break up air bubbles. This is done to prevent cavitation that is a big problem in 7.3s. Ford has tried all kinds of things to prevent it. There was the "coolant conditioner" that was supposed to stop it.

Just replaced my heater core, $1300 later, I'm adding a $200 coolant filter so that never happens again.

Well they also stop cavitation by providing a medium for vibration to scub off the block rather then metal

Yes they work great. All that crap that sits on the bottom of the rad is filtered out. Water pump has clean coolant. You have oil filter, gas filter, diesel filter, trans filter. So why not coolant filter.

Im a trucker dying of cancer but still trucking to hell with cancer and with 6million miles under me Yes coolant filters work.

Not going to lie that looked like transmission fluid at first

One of the best upgrades I ever put on my 6.0

It's about stopping electrolysis that's what causes the rust . It adds recharge sca to the coolant

man put less miles on in 3 years than I do in 1 lol

Just drain your fluid when recommended. Only time you really should have one is when dealing with sca.

For a 220k motor that’s a solid test too, safe to say it works

they also add DCA which is vital to combat corrosion and electrolysis.

Always kinda wondered about this myself lol. See it a lot on medium & business class trucks

Didn't think Bert Kreisher knew much bout cars

I have one on my 4 runner I just got(it's a 95) I also put a fuel water separator inline frome my tank to the motor and ditched the tank filter 10 microns filters a ton of stuff you would never know about

You really only need a coolant filter if running the older coolants that have nitrites (like Ford Gold). Ford Orange (now obsolete) and Ford Yellow (replacement for Orange and also miscible with orange) do not have that additive (was meant to, or thought to have prevented cavitation). Because of that, if your run those new coolants and your cooling system is CLEAN AND FLUSHED IF IT HAD THE OLD COOLANTS and you switched to the new good stuff, then you do not need a coolant filter. But if you run Gold or older, and have a 7.3/6.0/6.4, coolant filters are an excellent BACKUP to changing your coolant every 60K religiously.

Nice can opener.

Do you have any more info (regarding the filter system you used on your truck) that you can share with us?

I just want to know where you got a filter opener.

Coolant filters do filter however unlike oil they are a closed and sealed syestem meaning they should get next to zero contamination. Your coolant system also doesn't have tight holes for it to go through that would get clogged up buy the minuscule amount of sediments they may acrue over time. Most of which should be flushed out during coolant changes.

It’s technically not a filter, there’s additives in the canister to prevent cylinder cavitation an air bubbles in coolant

Not a diesel guy, never heard of a coolant filter before. Are these diesel specific, or are they made for gasoline engines too?

If you only use distilled water and coolant and flush at the recommended intervals like nearly all manufacturers recommend it becomes pretty much a non issue.

Is anybody else questioning how this man has only put 20k miles on his truck in 3 years?!?! I put 20k a year on my car!!

coolant filters on the 6.0s would have prevented alot of grief

We got em on our dd15 engines l, 30k service for all fluid filters. Those coolant filter come out nasty as shit.

They should have a small magnet to catch bits of rust from inside the block ❤

A better question is why one would think that a filter designed to filter coolant wouldn't be filtering coolant

Yo the machine workin on cars now??!?😂

Diesel engine have coolant filters have Anodes in the filters to stop electrolysis because the block cast iron and cylinder steel alloy causing acid to eat the linner.

How often should you change this on a diesel

How do you get one installed? May be there's universal screw on ones that have a plate you make two hoses in your cooling aystem run through? 🤷🏼

Do you recommend it for gas V10’s?

I leak about a gallon of coolant per 5K miles. No need for a filter when you basically flush the entire system every oil change 😂

You know what maintains a cooling system??? Change the damn coolant. Every 3 years for conventional and every 5 for extended life. Our shop only does cooling and a/c related components and we rebuild and repair all heat exchanger for farm,fleet, off road machines and of course automotive. Biggest thing I run into is corrosion or for brass and copper rads solder bloom which is a white crusty rad murderer that shows up when lead has met it’s half life and separates from the tin. To slow those kinds of things down you must change coolant at the recommended intervals. And of course the filter will pick up stuff from the system because all metals involved break down and deteriorate and will leave deposits that will make their way to a filter in-line if you supply one. But changing the coolant and flushing the system with a garden hose because you want volume to go through the system and then seal her up add coolant and remove air from system then once thermostat opens close the cap check if your heat works and move on. Even if it does work a coolant filter is a waste of money in my opinion which doesn’t make it fact lol. And I don’t want to hear about using garden hose because of hard water. Unless it’s a well your getting your water from distilled is also a waste of money and the conditioners provided in your fresh coolant will take care of all those concerns I promise this is all I do everyday and have never had someone come back and say your ruined my car using hard water from the tap lol

I need to install a housing for one of these in my grand am. Previous owner took horrible care of the engine, and now it has pebbles of oxidation in the coolant system

Vw needs that

If you change your coolant when it needs it you don’t need a coolant filter , that’s for if you know your not going to service the coolant

Can you modify it for older systems ?

They filter out rust eh? Thats the only thing i could think of because coolant is basically just glycol and water

If, on the day you buy it, you have the engine properly flushed and prepped, and filled with Evens Waterless Coolant, you likely won’t need one of them.

Does it effect the flow. I mean hauling up a long hill ur system is already taxed. Do a delta P test install guage before and after inline

I read cooant filter is menditory in diesel engine to prevent cavitation

Manufacture don’t install them because they become another maintenance item and the risk of not having it during the warranty period is not high.. it’s the same thing with oil catch cans. I installed one on my 2019 raptor and I catch a fair amount of fluid..

I could have told you from flushing my own high mileage vehicle that it would capture sediment. My vehicle manufacturer doesn't recommend flushing only drain and fills.

Is it an engine cooler or engine oil filter.

Does this put strain on the water pump?

A suckers born everyday. You can sell anything to diesel guys for insane amount of money.

They arnt actually a filter, the add a chemical into the coolant to reduce cavitation in the cooling jackets around the cylinders

Is that a filter opening tool?

Please explain to me why you need to remove "contaminants" from the cooling system with a filter? Coolant requires changing every few years, and the system gets flushed out at that time. All it does is cool the engine and stop corrosion. Particles floating around in it will harm absolutely nothing. Admittedly, I work on cars, but I have never seen a coolant filter on one in Australia in nearly 30 years.

Why are you running dexicool and not green from factory?

Seems like if you're replacing the coolant at the proper interval then this really wouldn't be necessary.

Never even knew these existed before now

Not trying to be a smart ass and I am actually being serious, how does contaminants get into coolent? It's a closed system that is capable of containing some amount of pressure, so how does coolent get dirty? I've replaced it on multiple applications and vehicles and I've never seen perfect coolent come out unless it was recently replaced.

I use to make those filters

I don't doubt that it works, but does it work better than doing a coolant flush regularly?

Rather than moosh it together you might want rollers like an old timey washing machine

I'm more interested in that can opener....

Bert Kreisher works on cars now?! At least he gave up the comedy gig

For such reason it’s important to do a coolant flush… depending on the driving habits of a car owner it can be once a year flush Once every two years But never run the same coolant for a long period of time Just like all the other fluids in the vehicle it looses it’s ability to do it’s job

I drain flush refill thermostat and cap. I don’t see the benefit of a sediment filter. If I’m doing that every year before fall.

Very cool no i want to install one somewhere on my line

Are those contaminants or properties of the coolant being captured? How would paper discriminate between contaminants and properties?
