Typically the first cooler that your seawater sees coming from outside the boat is the transmission cooler. It is also the most expensive one to replace if there is a failure. So this cooler should be put on its own schedule. If raw water was to get in the transmission this could cause you to have 3 to 5 transmission oil fluid changes to remove the sweater from the gearbox. And sometimes that still is ineffective. If it’s saltwater you’re trying to remove, it’s even more harsh. So creating a preventive schedule for changing of the transmission cooler is critical. It should include regular anode checks up front and some relationship with an experienced marine mechanic if your experience base is low.
The others, which include your fuel cooler, power steering cooler and engine oil cooler are also critical to the boat’s operation. They should also be checked as above but with less intensity unless anode replacement from your transmission cooler check becomes a unusually frequent. The first two coolers are the most likely to see electrolysis. Use those checks as a guide for developing a replacement schedule for the rest.
