coolant leak

[00svtlightning]

I have noticed a coolant leak under my truck. Its an 03 psd with 163k miles. Ive noticed a small residue around the cap on the coolant tank. I am wondering if the coolant leak is egr cooler or egr line. I also have to replace the icp sensor so if i need to replace cooler i am going to wait about sensor since ill be removing the turbo. The anitfreeze level has gone down very slowly over the last 5 months id say i havent had to add any but its at the add mark now. At first i assumed headgaskets but now i am thinking cooler cause ive got all this antifreeze on the bottom of the engine. Also the icp may not be the problem ive got the low icp pressure low code, truck will not start, im wondering if it could be the hpop. Id like to know so i can change all these parts at one time.

ive just found coolant leak its the orange hose under the turbo. looks like the turbo will have to be removed to fix?

I have the exact same problem. This weekend I removed the turbo to change the hose and I am going to change the ICP sensor too because I think I have an oil leak from it. Pain in the rear end.

I am going to take my icp and ipr and try them in a truck at work and see if there bad that way. If there good its more than likely my hpop. Luckily the trucks at work have a doghouse for easy acess to the rear of the engine.

the turbo doesnt have to come off to fix it , take the cac tube off that side , and remove the two torx bit screws out of the housing , pry carefully up and the whole thing will come off , reinstall the new hose and reinstall the housing as a unit

Ive got too take the icp and ipr off one is bad hopefully if not then the hpop is, so i figured with the turbo off ill just change the leaking hose then. And since i am going to check the sensors in a test truck at work which has a doghouse for rear access, it will be just that much more taken off if my hpop is bad. Besides i couldnt even feel the icp valve and just barely see the ipr. Looks like id be time ahead removing the turbo.
