EGR Cooler Question
If Ive over heated the truck Ive been told that the egr cooler could melt... now lets say my egr cooler is melted but im doing the egr delete mod. Would I have to replace the egr cooler? or just leave it and make sure the coolant hoses are in good condition?
thanks
thanks

so are you doing the egr delete mod or just blocking it off? they are 2 different kits. the delete kit is just that. it takes it out of your truck completely. the blocking kit blocks the inlet and outlet of the exhaust flow into and out of the egr. if you mean the blocking kit then no, you would not have to replace it because the coolant will just fill the egr tube and still go on about its course. unless of course you dont seal off the ends good enough then coolant would be leaking out the ends of the cooler onto the top of the motor under the intake.
hope that answers your question

Blocking from the up-pipe will block the exhaust flow through the EGR cooler but not the coolant flow. If the EGR cooler has been damaged and is leaking then you'll need to replace or remove it.
- EGR block-off or bypass only blocks the exhaust from going through the cooler
- EGR delete removes the EGR cooler completely, no exhaust or coolant flows through

i am taking pics for those that want to know how to do it or take the pics to someone else and have a shop make it. it is quite simple but time consuming. i thought i would delete it while i put in my headstuds as well.

on another note, you still need that coolant flow that is supposed to go through the cooler.

oh and for the experts I have a question... there were scuff marks in the cylinder walls not all of them but some... they were in a vertical direction looked kinda like dark lines but when we ran our nails across you could not feel any grooves what so ever it was just visual marks, my heads were warped and getting resurfaced but those scuff marks were my only concern... maybe the rings are bad too? i dont know... she never lost any power.

Hey George, How much are they machining off the heads? My understanding is there's not much material for 'shaving' the heads. Just a cautionary note for you, a lot of Techs replace 'em instead of maching them flat.

yea im blocking it off from the upipe and blocking off the entrance and exit to the egr cooler as well. Here are some pics from a few hours ago.. Im also replacing the entire cooling system because I blew the radiator and even went as far as melting the reservoir tank up top behind the air filter...
