Water/Coolant Filter

I was doing a site visit today, and a thought came to me while looking at a diesel generator. Why don't they put water/coolant filter systems on normal gas engines in passenger cars? I wonder if the system would benefit from this filter set-up or just be over kill. Seems like it would be pretty easy to plumb one in on the 4.0.. Thoughts?

I had one I put on my 7.3 Ford Powerstroke. I have never heard anyone say the leftover block casting sand was a problem on the 4.0 gas engines though. Something to think about though.

Since NO vehicles come with them, the deduction would be zero benefit. Why would it need to be filtered?

Aside from the overflow tank, it it a closed system so nothing would get in.

The only contamination would be from corrosion and that would be from weak antifreeze.

The passages are not that small.

They are on some vehicles, mostly diesel engines and industrial applications. They are closed systems as well. When used in diesel engines some of the benefits according to the WIX site are

Properly installed and maintained, coolant filters help to provide:
A clean, well-functioning engine cooling system.
Proper engine heat dissipation.
Engine efficiency through improved heat conductivity.
Method to introduce necessary Supplemental Coolant Additives (SCA's)

Plus with the filters that are treated with corrosion inhibitors, that would be a bonus as well as corrosion is one of the biggest problems in any cooling system

Electrolysis of the water will destroy a diesel engine, that is why the SCA's are so important. Commercial trucks can go a million miles before overhaul and I don't think any gas engines need to worry about lasting that long.
