what i have done
 

Thanks for all you diesel guys with the info on these 6.0's. Since reading this forum i changed my fuel filters, installed a coolant filter, and cleaned my egr valve. already knew how to do the other easy stuff. next is a edge monitor for coolant and oil temps. then its new egr cooler and sct with mild tune! JR

Hey man, Nice job! I have 6 different boxes full of parts to bolt onto mine when I get some free time...

Sounds like a good start! You going with a bulletproof EGR cooler I'm assuming?

yep
 

Yep the bullet proof or the sinister. I forgot, i also ran down the vacum leak that was causing my air conditioner to run thru the defrost. this site is great!

I still need to do that myself haha

Being in the People's Republic of California stinks when it comes to bolt ons. If your smog test is every 2 years, I'd have 2 exhausts, one cat, one 4" staight pipe. A friend maintains 2 h-pipes for his Mustang there.

Regardless, one step at a tim3, check temp split before doing egr, or you'll take it apart again for the oil cooler like I did.:argh:

so thats why my ac blows through the defrost

i have been banging my head trying to figure out why it is doing that

I just seen this about the A/C I was wondering if anyone has/had this issue. A/C and heat both will work fine for about 20-30 min or so. Then it will stop blowing the air strong. I can hear the fan blowing on high but hardly any air coming out of the vent. If I shut it off or switch it to defrost or the feet setting it will come back. Somtimes the A/C I think freezes and I have to turn just that off and then the air will blow strong after a min or 2, then I can turn the A/C back on. Any one heard of this?

yep
 

it was pretty easy. followed the write up on how to diagnose and fix. Hint: before you take your dash apart, check all the engine compartment hoses:) :dang::dang:

idk about the laws in cali but if i were you id just get the egr deleted. Iv heard bulletproof is the way to go though.
