I have a small coolant leak around egr cooler!!

[08 King Ranch 6.4]

Under my truck today using some liquid wrench on some bolts preparing them for removal and noticed a small leak looks like it is coming from the coolant line on the lower egr cooler but I am not 100% sure. What should I do?

[Doss]

Depends on several things.

Do you want to go ahead and buy a tuner and EGR delete kit?
Do you want to buy stock coolers and replace the bad ones?
Do you want to buy upgraded coolers and replace the stockers?

Thats what I was thinking. Out of the three options here I sat down and ordered all the goodies. Mini max, S and B cai, sinister egr delete, and 4" flow pro. Hopefully I made all the right choices. THOUGHTS PLEASE???

EGR delete with elbow? Regardless, I think if you ordered all that stuff you should be fine. You'll just need one good weekend to tackle the whole install.

While you're at it and in a spending mood, get a coolant filter and some new coolant for your truck. It's a good time to do both since you'll need to drain the coolant from the radiator and overflow tank to install the EGR delete.

1 No elbow. Should I? If so, what is the pros of it?
2 coolant filter??? Didn't know there was one can you please explain the pros of it. Shouldn't coolant just be coolant with deletes installed?

I asked that wrong. There is nothing that mixs with coolant with no deletes. Right? What does the coolant filter filter out of the coolant?

Check the upper rad hose for the leak mine was leaking there and it was directly under the cooler if the hose ends are black in color they are the old design with single o-ring the new ones have double o-rings and have white ends.

I replaced that hose last coolant flush. I can't find the leak it is very slow

Check your radiator itself. The seal between the aluminum and the plastic tanks can start to leak. I've had that problem.

Make sure you didn't puke, I went under my truck looking for a oil leak and notice my lower cooler was a little wet, but then I start to think about my puking problem that I was already aware of, so I opened up the hood and saw my degas bottle that was wet and leaked down on my cooler. You might want to take a look at that, I know it's not really common on a stock truck to puke but you never know!
