    Transmission cooler replacement to do or not?

    Looking for comments on replacing an original transmission cooler on a 1996 250 hino wo6ta. I have not had any issues with either one and have them both off for cleaning, there was some scale with partial blockage of 2 tubes but this cleaned up easily with a muriatic acid soak. Do people recommend replacing these or simply clean and maintain? Thanks!

    Depends on what kind of raw water goes through it as much as anything. Fresh water is usually kinder than salt water. I suggest having them pressure tested before you reinstall them. Iiwm, and I’m in salt water most of the time, I’d be shopping for replacements with a plan to replace them pretty soon.
