Not to be confrontational, but what would be the point? The cooling system is a sealed system, no contaminants would be able to get in, and if you have rusting, scaling, or particulates in your coolant - time to change the coolant.
That said, I may be able to see one on the expansion tank, but even so.
I wouldn't use one like that, but there are actual bypass coolant filters you can use. Debris can happen in a cooling system, like casting sand, rust flakes, and rubber pieces. Just because you maintain the cooling system, doesn't mean the previous owners did, and there may be problems in the system.
Cooling system contaminants, (like some other substances,) happen.
Having the transparent housing seems it would be easy to see if a problem were to appear. (Oh, there's that tiny socket I lost!) I wouldn't bother with one in a newer vehicle. I have read that most over the road trucks have coolant filters.
Ford_Six, what is the story on "bypass coolant filters?"
One of the most efficient types of coolant filters are the type used in marine apps.A friend of my familys installed one on his semi tractor.You would not have beieved the crap that was removed from the cooling system of his truck after one coast to coast trip.Fine sand,(most likely from the sand core from casting the block)rust flakes,rubber particles.Just to name a few.

Wouldn't flushing the system take care of that? If it get's trapped by the coolant filter, it would be removed when the engine is flushed.
All that aside, what are you gaining by removing those small fine particles? Obviously sediments in the coolant will wear the pump over time, lodge in the radiator and reduce cooling levels. I guess a moderately priced item that doesn't restrict coolant flow and captures debris isnt' a terrible idea really, if it saves you from buying a new pump at 100k.
I'm just having a hard time understanding what it would do that flushing the coolant every year wouldn't?
This shows that you can sell anything. Who would have thought you could sell tap water for over $8.00 per gallon by putting it in bottles. My son-in-law works at the bottling plant anf they take tap water, run it through a filter and get big money for it. PT Barnum said it best.
Ok, by that reasoning, take your oil filter out of the system and just be content to flush the oil every few months or thousands of miles. Even if you flush the cooling system every year, that crud is circulating and causing wear and tear for up to a year. I'd say it's probably not a bad idea.

You poor confused soul. Oil gets dirty and coolant doesn't. Coolant loses its rust inhibitors and water pump lubricants and that is why it is changed (a filter won't change that). Worn out antifreeze can look new and some people don't change it for that reason.
Great link Steina. Well written and good illustrations too. It certainly points out that there is value to these screen type filters, especially after the engine has been opened up.
