  1. Another new oil cooler?

    6.4L Power Stroke - Technical Info
    First post So my EOT is getting up to the 230s running 80mph without a trailer, while my ECT is 192 and never goes above that. I replaced the oil cooler 6 months ago and have a filtration kit on it that I change every 4K. Could I really need yet another oil cooler? It’s stock ride height...
