Oil Cooler and Delete ??

1589 Views 7 Replies 4 Participants Last post by  Ford06
I just started pulling a 29' 5th wheel and my EOT and ECT deltas are 15-18 degrees on average. I installed a coolant filter and switched to Zerex ELC in the last two years. Engine has 157K miles. I'm pretty sure my oil cooler needs to be replaced. Is this the time do to an EGR delete as well ? Should I do a delete ? Will I have to do a tune to get the computer from throwing a code ?

I don't think the early '04 was a problem with the removal throwing a code. I think it is 05 and up. Late 04 may be a toss up as to whether the updated parts were used in it.
)4's were different early vs late builds. Is the EGR cooler round or square?
Rock Doctor: Do you know what size freeze plugs that takes?
