Hi all,
Was wondering if anyone has installed a spin on coolent filter on their mb? I plan on doing this in acouple of months with mine. I like the one I installed on my truck.

thxee all for your comments & suggestions

Great Idea, I've wondered why more car lines don't have coolant filters at least as an option. I wonder also if there is a good method to keep the PH balance stable over a longer coolant life?

Only option now is frequent coolant flush-changes. If you do this please post your results.

wasn't really worried about the ph, just the filtering. That is something to wonder about. I know they have filters that release centain chem. to control cavitain, but have been told that isn't an issue with mb's. After seeing pic's from the dieselstop 6.9 forum, I was totally fabber-gassed at all the crud in the cooling system. The one on my truck after 6 months, was real bad, but looked much better at the next filter change. Now that ph has been brough up, what is the ideal ph for a diesel? 7-8 maybe?

Is the filter inline with the radiator hose, heater hose, tank hose, etc.?

Wouldn't a filter restrict the flow making your water pump work harder? Since this is a closed system why would you need to check Ph of COOLANT. If you blow a head gasket. This won't solve the problem. You will have Milk Shake for oil.

Hello,

My personal preference is to place the coolant filter in the cabin heater supply line. The filter only works when you use the heater or defroster. The good thing about this location is that the coolant filter does not add any additional restriction to the cooling system. You may notice a slightly different knob or lever setting to use the heat only if you have a manually controlled system.
If you have an automatic temperature control I don't think you will ever notice any difference (I havn't).
Other than routine service (changing the filter cartridge and refilling with coolant to replace any lost coolant) these things generally just do their job. I was surprised at the amount of crud the filter removes from systems that look fairly clean.
There are coolant filter kits that have additives advertised to have supernatural powers. I have not used any of these, my usage has been the plain-jane filters. The additives may be great, I just havn't used any of them. Luck...

Hi Charlie,

There was an excellent tread floating around here just a week or so back that had very informative dialog about the degradation of coolant. Some of the discussion was over my head, (i'm short).
The summation was that coolant does degrade especially in the recent years of aluminum power plants and exotic metals used in some of the coolant systems.
I manage a fleet of 75 vehicles that have a lot of different uses from construction activities to highway miles. Most of the moderate and heavy duty coolant systems come with coolant filters; the ones that do not, we add a filter system as soon as practical.
I recommend them but there are a lot of folks who, by regular maintance and coolant changes may not have a burning need for one. Coolant filters do not take the place of regular coolant flush and fills.
Luck
Al

anybody done this yet?

how about before the aux pump or on the lower reservoir hose?


What models in the junkyard might have spin-on housings as a donor?

I just checked Ebay; they have Coolant Filters as well as the Filter Head/Mounts.

thanks,

I went through all that stuff and I definitely need a cheaper solution (besides the inline screen mesh - lame). I'm not really hung up on filtering the coolant on a regular basis, but I have some elusive sediment that just won't go away after doing some really serious flushing last summer.

Almost all of these filters will fit our fuel filter housing... I might just rig up one of those.

When I looked at the Ebay stuff I was thinking a Filter Head/Mount for an Oil filter could be used but then I remembered the threaded portion of the housing would need to be Stainless or Brass.

The Polyeaster (not polypropholene) filter bag material that the alternate Fuel Folks use could supply a cheap Filter Element material if you were willing to do a little cutting and sewing. And, the bag filter material is supposed to be washable.
However, you would have to invent a Filter Housing to use it in.

I actually ran my coolant that I had drained from my radiator through one of my 1 micro veg oil bag filters. It left a nice residue inside it and the coolant looked nice an clear again.

Cant say i've ever seen a filter on coolant.. what purpose exactly would it make? most filters on diesels are simply a chemical leeching system i'm pretty they really dont filter anything and since the design doesnt warrant sca's i dont see a bonus. 300-1 million miles shows u just have flush it with new from time to time

why is that?

there are many parts that are aluminum along the coolant line...


or do you mean the bolt I use must be stainless... ? the block itself gets rusty... I don't understand the concern.
