What do you think it means?

[6literdiesel]

I put my coolant filter on a little while back and I ran the initial filter for 1,000 miles. I was going to change it at 500 miles, but it was always still hot to the touch so I took that to mean it wasn't clogged. At 1,000 it was still hot, but I changed it anyway. I now have about 4,000 on thesecond filter and it is still hot to the touch. From what I read I was expecting the first two to clog up pretty quickly. How do y'all interpret these results? I'm hoping its a good thing.

Is it possible that its hot because engine coolant is flowing through it?

What he is saying is that he expects it to be hot due to the coolant actually flowing rather than the filter being clogged and causing it not to flow through there.



OP, the filters are cheap insurance. That said, I would go ahead and change it out. It won't take much coolant going through there to heat it up. So, it could be mostly clogged, but not completely. With mine I did a change after the first 2000 miles (I waited this long because I installed it after a flush). The second change was after another 2000 miles and the third I am going to leave on for a year.

Which is why he's asking the question... it's not expected to be hot (flowing coolant) ~1,000 miles into an initial installation. Seems that most people find it clogging 200 - 500 miles down the road on the first filter, then anywhere from 1,000 - 5,000 miles on the second.

OP, maybe that means you were lucky and didn't have the casting sand that many do? I've got 500 miles on my first filter and it's still flowing, so maybe I got lucky too?

OP/dieselmatt, did either of you cut open your first filter to see what was inside?

I had every intention of cutting it open, but then I got lazy and threw it out after it sat there for a month and a half.

i don't think touching it to see if it's hot is a good method ,
cutting it open is best I tin snips) so you can see whats going on now I just do mine once a year
since very little sand has ever been present and My block was flushed and new coolant when they did my heads

Sounds like something I would do

I think you should be happy that you don't have that much crap in your cooling system...

But in the other hand that wount tell the whole truth.

Like i have the worst possible scenario with my cooling system, so much rust scale from block and heads that i'm on my second oil cooler now and i have had to back flush that one open about 20 times allready in a year.
Now i have third one on a table waiting when i have time to do hg's job again..
Last time was about 8000miles ago.

Anyway i have used six filters with different milege and never get the filter clogged. But the oil cooler clogged totaly evry time... Evry time when i do the flush i collect the debrees what comes out and its about one to three t spoon evry time. And from the filters what i cut open have collected only 1-5% of it.
