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 using an outlook monitor and by putting cooled off water back to the degas bottle I'm running 8 degrees cooler.

Gotta go to work, talk to you guys later.

 

This is intersting maybe worth further testing..

 

Can you take some pics and post them so that we can see how you placed your coolant filter system?

 

My coolant filter made zero (0) difference in operating temp. And I watch temps closely.

 

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.

 

20 mile test 10 with cooler oil temp 207 water temp203 10 without cooler oil temp217 water temp206 at 75 mph on the freeway pic later

 

look at the degas bottle it doesn't make a loop with rad to cool the water
so you are putting hot on hot

 

Yes, it is hot flowing to hot. But the purpose of the coolant filter is not to cool the water, only to filter it. The radiator does the cooling, and the flow through the radiator is the same whether you have a coolant bypass filter or not. So the net cooling load should not change. The only thing you could possibly expect is that your cabin heater would not work as well, but the hole in the bypass filter is so small that I don't think you can even notice any difference there.

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.

 

all i can say is try it and you will see a dif trust 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.

 

I think he may have a air bubble running around the cooling system....Scott
