So, can, or, do silicates get filtered in a standard coolant filter? Besides the silicates that "drop out".

Just standard filtering, mind you.

One reason why I ask, the last filter clogged at 5000 miles. Cut it open and really did not find any reason for it to clog.

 

I had a coolant filter do this too cut it open and really couldnt se anything that would cause it to clog a little grit but nothing majoir



I check the filters more often now IDK

I really coldnt beleiv that it was plugged up after what I saw when I cut it open but there was no flow in my return line changed it and had flow good again

 

That is the same with my last one. Heck, I let it dry out for more than a couple weeks hoping to find something. Never did find anything. New filter flowed like normal as far as I could see looking at the degas bottle.

 

what are you running for coolant in that 6.0?
what filter plugged up on ya? brand/model #?

cus for example,if your running ELC coolant,and you put a filter on charged with SCA's for standard coolant,this would be my guess as to why she plugged up.SCA's are not to be used with ELC.ELC coolant protects the cylinder walls differently and cannot be added.the results would likely be a sludge buildup and a plugged filter.
perhaps your using standard coolant (though i doubt it) and used a pre-charged filter with too many SCA's and the same thing can happen.
if your running ELC coolant,you'll want to be sure to run a blank (non charged DCA filter) to avoid the sludge build up/plugged up coolant filters, such as NAPA #4070 or Wix #24070 for examples.

 

Do the charged ones always say they're charged?? I.e. what brands are safe with ELC? I run the Napa 4070 which I know is safe.

 

When I changed to ELC Final Charge it said on the bottle to run a non charged filter with it so I use the same as you Napa 4070 non charged filter

Its also supposed to be non charged for Ford Gold to

 

I'm on my last Baldwin that I ordered extra when I bought the kit. They are not charged.

I have never looked at the labels on a "charged" filter. I've heard they "rattle" when you shake them. Again, I don't know.

There is a list of compatible filters that are non-charged.

There is a short version of the baldwin, don't have the number though.

 

I know these are all non-charged:

The filters may be clogging from the so-called "goo" that may not be readily apparent without cutting the filter open. IDK why some trucks get the goo and some don't. There seems to be no rhyme or reason to this mystery.

 

Some are also loaded with casting sand and others have none. Some oil coolers plug in 10,000 miles and others never plug. Some of the 6.0 mysteries.

 

Sand? Yes first couple filters.

But the over all question, since the Gold has the silicates, can or could they coat the filter and plug it?

Certainly not immediately, but over time I'm thinking the trucks running Gold would change filters more often than those running ELC. (And I'm not saying this to advocate for changing coolant to those who haven't) And more often, I mean, like thousands of miles difference.

 

Ok Benny, what was your time frame. Coolant filter vs. Coolant change?

For me coolant filter was first.

I have flushed twice after filter. First flush was with VC-9 (and of course using distilled for final flushes) Then, I wanted to put the new coolant (Ford Gold then) through a "life" cycle. Which was a little over a year. Included heavy towing, grocery getter, long commute.

Second flush was after the 5000 mile clog. Changed coolant to John Deere CoolGard II. (now don't bash my choice ! we are all doing some things a little different than others) (yes, the JD does have silicates in it)

Now I will see how long this filter lasts.
