Coolant filters???

I have certainly thought about it. There are those on both sides of the argument. But since the filters are "bypass" filters, they don't interrupt the regular flow of coolant and therefore don't really have a downside, in my opinion....except for maybe the initial cost. Whether it's worth is up to you. They can even be installed with ball or other type shutoff valves so they essentially are no longer in use if you so choose. The valves also aid in changing the filters quickly and easily.

There are at least two types I've seen. The canister type, like and oil or fuel filter, and the screen type that go in a radiator hose. They have a clear section that has a screen in it to capture the particles.
Here's a review of one of the latter type; http://www.jag-lovers.org/xj-s/book/CoolantFilters.html

I use a Gano in line screen filter in my Toyota FJ60. You can see through the tubing to observe it it needs to be cleaned or not. It is very easy to clean out and then I have to top off the coolant and "burp" the lines to get the air out. (It is an FJ60 thing).

Dunno, never really seriously looked in to it.
In all the years I have owned a disco (thre discos), I have never read or heard about coolant sediment being a problem. Especially given that the coolant is supposed to be changed every 15k miles (if I remember the service interval correctly).
Yes, people who own diesel engines (especially the Navistar engine Ford uses) use them. But that is something specific to the 6.0 power stroke diesel engine. When I had my F350, it was highly recommended. I dont recall the cummins or duramax diesels adding the coolant filters as much.
Anyway, yes you can do this. But do some research and you'll find that this isnt an issue.

Most people can't account for coolant changes if they weren't the original owners of the vehicle. Both my rovers have had radiators that were clogged all to heck. That stuff had to come from somewhere.
1) the fact that the original poster is worried about coolant sediment more than likely indicates he watches his routine maintenance carefully. So, I would bet he changes his coolent often enought to take care of any sediment.
2) My point is, it certainly wouldnt hurt to add a coolant filter, I am just saying that it isnt necessary if you are following the appropriate service intervals. It doesnt cost much, and if you really want to do it then go for it. It just isnt necessary.
3) Yes I am sure any vehicle will clog radiators if the coolant isnt changed. And Rovers like any other vehicle, after a long period of time, have to have their radiator serviced. Usually rovers get theirs rodded (or at worse, replaced) once the owners realize the engine is overheating. Rover engines are much more forgiving to overheating than the 6.0 powerstroke. Whose owners are aptly advised to install a coolant filter.
So those were my points. Thats all.

I coolant changes at one year. Roughly 15,000 miles. I just bought a new radiator. I couldn't find someone to fix my old one. It is apparently clogged? I never overheated. Not sure. But least It is "all good" now.

anti-freeze is designed to hold in suspension any particulates. So if you change out the coolant periodically you will also remove any particulates. Back flushing through the port in the block is effective. On older engines you could very well create problems by removing these particulates as they may be blocking leaks.

A lot of sediment is a mixture of rust from iron blocks, heads and pump rotors, and limescale from the water. When I replace the coolant on my engines, I use a 50/50 mix of antifreeze (which has rust and scale inhibitors) and clean water from the drain tray of my clothes tumble drier (it's not a vented one), which means that the water has been evaporated off and crudely distilled, leaving dissolved salts and minerals behind. I haven't cut any radiators in half yet, but peering through their top caps/plugs shows that they're still clean inside. I also back flush the system with a water mains hose at full blast whenever the rad or water pump are removed to clear out any debris.
I'm sure I still get some rubbish in the system, but by doing these things, the amount is minimised and the potential for rust or scale deposit and flaking are almost eliminated. This avoids the need for filters, which could easily become a blockage or leak point.

Good points made by all^. I guess I never thought about a coolant filter. I HAVE installed a Cardone inline power steering fluid filter. About a year ago, my steering pump was beginning to whine. I completed a flush and installed the filter. (Works great; no noise.) The Cardone was under 20 bucks and easy to install. Of course, it goes back to the routine maintenance issue....
