coolant, filter, and temperature testing
I added the coolant filter and I thought the temperature was running hotter after the filter because you are pumping hot water right back into the degas bottle.
So I bought a single pass power steering cooler and hooked it up after the filter back to the degas bottle and it made a big difference in temperature. I wonder if you go from the EGR to a cooler back to the degas bottle if that would make a big difference also. Thanks for any info.
It seems like you are just pumping hot water in a circle by going back to the degas bottle.

What are you using to monitor temperature? FWIW--unless you have a tremendously large line going to the coolant filter, with the small lines supplied in most kits it's not going to make a hill of beans difference. The line that you tee'd into from the top of the radiator to the degas bottle is nothing but a radiator overflow line anyway.

I'm wondering if he doesn't have some other kind of problem. I can't see that small an amount of water making an 8 degree difference in 28 quarts of water.

I can't see any quantity of flow making a difference, considering it is coming out of the hot side and going right back in the hot side. Turning off the heater control valve would have a much greater effect.

Agreed. I'd like to have it data logged. I get a pretty good variance in temps just going from stop sign to stop sign sometimes. 8* is nothing in the grand scheme of things.

I'm not doubting you, just don't understand how it could be possible. The temps you posted seem within the normal variation to me.

I have one more test. I have to turn off the coolant filter to report those temps as if it was running stock. I will do that tomorrow after work. I have some pic but I don't know how to post them on here.
