little more hiss from work done ?????

[Rob D]

finally got my egr delete and 4" turbo back straight pipe exhaust installed and have the xrace from innovative installed. i am hearing a more of a hiss inside from what seems like the engine side. would this be natural from the changes or should i not hear it. it is not overwhelming and dont hear it at idle. i am thinking the new up pipe may be the culprit or the connections to the turbo. the clamps on the turbo both seem to be on correct and tightened up properly but if it is not normal to hear a little more hiss then i am leaning toward the new up pipe with the metal gasket.

on a side not the tune and exhaust are awesome. i also flushed the coolant and filled with chevron elc.

Stop right there, you are not suppose to put any other coolant in a 6.0. You need to only use the Gold coolant from Ford for a 6.0.

Hissing noise like you said is probably the up-pipes.

From what i have read on the site if you flush all ford gold coolant out the elc coolant is ok. That being said i only use ford gold.....

I personally use CAT elc - Im in the Marine side of the diesel world, and coolants similar to ford Gold cause silicate dropout and like to plug very important and costly things. However, if maintained correctly, ford gold is great.

Im not a good maintainer of my personal vehicles coolant. So i prefer the ELC

It is your up pipe or your y pipe it happened to me.. those clamps are tricky you need to make sure they are perfectly lined up. make sure you fix it soon your motor will be covered in soot.... Only use Gold coolant from Ford for a 6.0.........

well i took a 100 mile trip yesterday and when i got home i checked hoping to see a sign of where the leak might be, but there was nothing. no soot or discoloration.

as far as the coolant thing. the elc's are compatible with all other coolants but the more it is mixed with others the shorter its time to work (according to the lable). also according to the lable it is safe for all components and meets and exceeds most if not all manufacters of autos and equipment coolant requirements. so with all that info and the fact that maybe the no silicate could be a good thing, why would it not be worth a switch. i know some here are on the sarcastic side and have been running elc for sometime.

now i need to figure out this extra hiss.

I would say its the clamp from the up pipes to the turbo, my buddies did this after a turbo removal, loosen the bolts down at the exh manifolds and remove the clamp at the turbo re align it install the clamp, then torque the bolts down at the manifolds and re test for the hiss I bet it goes away. As for the coolant, as long as its a heavy duty diesel rated coolant, not just your regular prestone or peak stuff u get at the parts joints you'll be fine, I recommend flushing the system though. Personally I don't recommend the red colored elcs...especially the cat stuff, I've seen a lot of coolant leak and seal leaking issues with this stuff, I work for cummins and mainly work on semi trucks and I've seen this many times I'm not saying this will always happen its just something I've seen and don't like, I myself plan on flushing and filling with fleetgaurd es complete extended service coolant, its blue in color this is what I use at work in everything and see good results. I don't like the ford gold, and see no real reason to use it.... Just saying.
