1hdt coolant filter install (1 Viewer)

[9180ltd]

Just figured I'd toss up some picks of the coolant filtration install I tossed on my hdj81 today. It was time for a coolant change as the green coolant that was put in it after the wife had a rad installed out of town 5 years ago was showing more rust than I would expect. So it was time for some proper coolant with proper sca for a Diesel engine, and while I was at it I tossed in a new thermostat.
Just put it in today and will change it in about a month to see what it has picked up.
I made a custom mount that attached where the factory fuel filter used to live. On one side of the bracket a racor 2 micron fuel filter and on the other side the coolant filter. To the rear of the filters I have brought a hydraulic line up from where the oil pressure sending unit used to live and ran it thru a couple "t" fittings ( all 6000psi rated because that's what I had haha) so that access to the sending unit was easier. From those "t" fittings I also installed my mad man gauge sending unit and a mechanical gauge just to cross reference for accuracy.

Forgot to mention where I tied in.

Since I ditched the acsd years ago I figured there would be no better place, and it worked perfect since the ports on the block fit 3/8 hose and the filter head had 3/8 ports

So this is a bypass system correct (I.E. it will not block coolant flow if it becomes clogged)?

I run one of these on my PSD and it adds a ton of life to the coolant.

I have to politely ask why?
The system is closed to the outside and designed to run good coolant for many years/tens of thousands of miles.
If you have rust in there, run a rust remover, ditch the stuff, fill with good coolant and deionized water, and you are good to go.

If you have a continuous rust build up, you are running wrong coolant/bad coolant/tap water.

The system you are running looks quite limiting, considering the huge changes in volume of flow you are getting upon closing and opening of the thermostat.

Not trying to pick a fight, just interested in your opinion.

Cheers,
Jan

The filter is not meant to filter all the coolant all the time. Its like a bypass oil filter it slowly filters the coolant and keeps it overall cleaner. Its not only rust that is suspended and flowing through the coolant, its sand and grit as well. Almost all commercial engines (trucks, tractors and gen sets) use coolant filters to keep the coolant clean of suspended particles. Most actually use filters that have additives to keep the coolant in stable Ph, they have 450k mile coolant change intervals. We do not need those filters for our road going cars just the passive non additive filters.

Search Google images for pictures of the junk these filters get out the coolant.

This is as I would explain it. I work in the heavy duty industry and tend to treat my stuff as I treat work stuff that when maintained runs 12-15 thousand hours in between in frame rebuilds ( 5-800,000km) I'm not saying the cruiser motor will last that long however I'm going to give it its best chance. I have seen these filters pick up a lot of crap in the so called " closed " systems, and knowing I can maintain proper sca levels and a clean system via filter maintaince is piece of mind for me. Knowing how taxed the cooling system can get and the fact Toyota put plastic impellers on our water pumps I believe this to be a worthy upgrade ( 80$ all in)

Thanks so much for the constructive answers!

Yes it is a bypass system. What I liked with the way these trucks are set up is once you delete the acsd ( as most do) there is a unused in and out port begging to be used for this or a circulating block heater independent from the heater core. So you don't have to cut your heater core lines and install "t's". And if the filter does plug it has no ill effect on the cooling system ( nor does it in a standard "T" install)
Basically the only way to tell if it is plugged totally is to check the temp of the upper rad hose when running while hot and compair against the coolant out line of the filter. I believe I read in one of the cummins service manuals if there was a 30 degree difference it due for replacement.
As well once you put a good quality diesel coolant in you can use test strips once a year to check additive levels, and if they are depleting you can install a new filter with the appropriate "sca" content to bring it back into spec. This means your "automotive world every 2 year flush spec" goes out the door. I would not expect to have to drain my coolant for 5-8 years as long as yearly monitoring with periodic filter change is done ( barring other failures do not facilitate it)

Good call on the ford install, the 6.0L engine has a real track record for contaminants plugging the oil cooler causing it to over heat and rupture , cross contaminating the Coolant and the engine oil immediately.
The coolant bypass filter is a well known preventative measure for these engines ( we have a fleet at work)

No sir, don't lump me in with those 6.0 people lol, I have a 7.3.

I'm going to setup a system for my 2H too.

 

[9180ltd]

Ah haha ya it was a sad day when we retired the 7.3 fleet. We had a couple f-450's that crossed the 500k mark with virtually no repair engine wise. They were/ are one of the best diesels I have seen in a ford.

9180ltd! Sorry to dredge up your post, but I can't resist. Any more detailed instructions for a layman? Also and more importantly . My 1hdt seems to be getting either diesel or more likely oil in the coolant . Ever seen something like this before? It scares me !

Old post bring-back. I plan to use the rearward port which used to go to the ACSD from the block as the supply to the filter and then from the filter to the forward port on the block that used to go to the ACSD.

Is that correct?

 

[roscoFJ73]

Whats the reason for filtering coolant? Coolant becomes used when the Ph level of the coolant has changed and will no longer protect the metals in the engine. A filter will not protect the Ph level.

 

[Bisonthecruiser]

Capturing pieces of metal, sand from the casting process, etc. These are used worldwide in a ton of applications.

 

[roscoFJ73]

Toyota flush those engines thoroughly. I have never seen anything left from the factory. And if the engine is decades old, its unlikely to have any grit left in there. And grit being heavier drops to the lowest point of the coolant system and stays there and even more so if the filter is elevated. The other point is every time you add another inlet or outlet to a coolant system is that its another place to leak from.
If is suspected of having grit in the coolant, I would put a piece of stocking over the outlet and check it occasionally and you would at least see what is coming out if any.

For future reference the above e described hose route works well.
