Choosing a 6.0L Power Stroke oil cooler means quality construction, planning the EGR cooler at the same time, and committing to a full coolant flush.
Quality matters here
The 6.0L oil cooler plugs with sediment, so a quality replacement and, critically, a clean cooling system determine how long it lasts. Buy a quality cooler and address the contamination that killed the original.
Do the EGR cooler too
Because a plugged oil cooler starves the EGR cooler and access is shared, replace both together. Doing them at once saves significant duplicate labor.
- Bundle the EGR cooler
- Fresh, correct gold-spec coolant
- Consider coolant filtration
Flush the system
A new oil cooler will plug again if the contamination remains. A thorough flush and correct coolant are as important as the cooler itself.
Frequently asked questions
Should I replace the EGR cooler with the oil cooler?
Yes. They are linked and share access, so doing both together saves duplicate labor and prevents repeat failure.
Why flush the cooling system?
The sediment that plugged the original cooler must be removed, or the new cooler will plug again.
Does coolant filtration help?
Many owners add it to keep debris out of the system and extend the life of the new coolers.
