So I was doing some tinkering under the hood this weekend (cleaning up the POs shoddy wiring job
) and noticed on top of the EGR cooler theres a 5 / 10 written on it in grease pen. I'm assuming that correlates to it having been replaced at that time. The OASIS report showed up clean on the truck and there was no records of it having been done at the dealership or in any of the paperwork I have for the truck.
Is there a way to tell if it's an aftermarket delete / cooler setup without having to actually tear it out? I'm wanting to toss in a BPD Delete setup but going to save the coin if there's already one installed. The truck still has the stock EGR valve in place and plugged in with no CELs. I have yet to pull the EGR valve itself and see if it's clean / sooty / wet.
Coming off the pipe from the Oil cooler is a blue hose boot which from what I can gather is rather common for both stock and aftermarket setups. Based on the pictures I've been able to find the overall setup / dimensions of the stock and aftermarkets look the same from the outside.
So, is there any way to tell if my truck has an aftermarket cooler / delete installed without removing the EGR cooler?
