Coolant filter?
I seem to recall seeing here or somewhere the modification adding a coolant filter to our cooling system.
The installer Teed into the heater core lines.
It went something similar to the following:
I had a few questions as to why someone would do something like this:
Not all the coolent goes through the filter, how does this make the filter at all effective? In the oiling system, the oil comes from the pump and goes DIRECTLY through the filter, do not pass go, do not collect $200... In the event the colter is clogged, the filter has the bypass valve inside.
In the cooling system, not only does not all of the coolant go through the filter, but not all of the coolant comes out the heater passages either.
I can understand it would be a bad day if the filter blocked up and it were in line like the oil system rather than a bypass setum like this... But couldn't it have a bypass valve?
And what of putting it in the radiator line rather than the heater core line. Wouldn't that catch more junk. If the flow is too low, how about two filters in parallel?
And finally, is junk in the cooling system that much of an issue? Every time I've drained coolant from one of my gassers, crud has been from a corroding out radiator which'd need to be replaced anyhow. The radiator in the F350 is new. Changing coolant every few years should keep it that way.

When these engine blocks were made they were sand cast.... consequently there is/was sand circulating through the cooling system. Damage to the water pump etc was seen so the filter system was installed aftermarket. With the filter install came the option to induce SCAs at a regular interval to retain the numbers required over a period of time. If your truck has been flushed several times it could be clean but any time you open the system there is a chance of gasket sealant scrapigs, dirt etc getting in the system. It's just cheap insurance for those who want it.

Pele,
I agree with you. I might be able to understand a filter in series, in either the heater supply or return line, but they way you show it with ball valves and stuff seems useless. What do I know?? I am just a Dumb A## Electricain

Looking at the drawing Pele did it looks like you can shut the water off to the heater in the summer and run the coolant through the filter. In the winter shut the filter off and run the coolant through the heater.
I could see that working.
dieselF250,
That looks like a nightmare for the plumber. There are so many tee's I have to wonder how well the heater works.
Water out of the head which can go either to the heater or come to the front of the truck, then splits again either to the filter or down to something else.
Where does that line go?
And how does the coolant get back into the cooling system from down below?

heat output is great
the T closest to the battery goes down to a check valve then to a coolant heater that is connected to the bottom of the block neer the starter. when i plug in the heater the coolant flows out from the bottom of the block through the heater, through a check valve , to the heater core and into the head. best of all it keeps the snow off my winshied when parked
i need to take some new pics, i made the plumbing look better when i added a/c to the truck

No no no... The water is ALWAYS flowing through the heater.
The ball valves are so that one can remove the filter without getting too much coolant everywhere...
EDIT: I found the link to where I originally saw this installation:

How often do you think you would be changing the filter on that coolant system? I'm thinking, after reading the literature that Pele posted, it might be a good idea to install a filtering system on my rig...
