Sinister Coolant filter---change intervals?

[Kappa Sig]

My dad had one installed on his truck recently (along with a new oil cooler/egr delete/insight). Been about 1500 or so miles, and deltas have been great. He hooked to a tiny little 5x8 enclosed trailer this afternoon and has delta's over 20 degrees.

Could it be the coolant filter element is clogged and needs replaced? How often do these need changed? First few times anyway.

THanks

I changed the first one less than 500 miles in then the second one after the next 500 now I am at about 1000 miles then I will go to every oil change

Thanks. Dad is picking up a filter in the morning. I finally went to the website and it says first change at 500 miles. Installer didn't mention that to dad so he didn't know (and I didn't think about it).

Could the filter being pretty well clogged be causing the high deltas all of a sudden. Before today, he was seeing 5-8* all the time (unloaded). That little trailer shouldn't have done anything. Even after he dropped it he had deltas of 15-16* this afternoon.

I hate to tell you but i dont think the high deltas are from the coolant filter. Its just a bypass. I believe the only filter that would require cleaning to make the deltas go down is the one from IPR. I could be wrong tho.

Man I hope you are wrong. Flush was done before new oil cooler was installed, and coolant filter installed. Hard to believe new oil cooler plugged already.

He is correct, that filter has nothing to do with your deltas. Make sure the cold soak temps are within a degree or so before startup. It's possible the water pump is taking a dump, or the fan is not operating correctly, tell him to see if he has unusual trans temps also.

Well new filter and still high deltas. I should have known better. 20* most times. Ect 180-185. Eot 200-205.
First...should he quit driving the truck? Second...any recomendations? Havent checked the cold soak temps yet..good thought. But I think the gauge is right since it showed great deltas for the first 10 days or so. Should back flushing be an option?

Thanks all

Backflush didn't help me.

So did you change to a second new oil cooler and now ok?

the 180-185 coolant temp is maybe a little low I went though something similar, changed out my thermostat and it brought my temps more inline. if the thermostat it stuck open even slightly it will throw things off some. also have you checked it again without the trailer
