Just checked my intercooler and oil cooler zincs. Both were completely shot after only 85 hours and about 4-5 month's service. Both had come apart in large pieces. I removed the aft plate to the intercooler and cleaned out the debris. Some of the lower core holes were blocked.
Any thoughts on the use of these zincs? Obviously, if they're deteriorating that fast internal corrosion is a concern. On the other hand, if they perform their job by breaking up in pieces large enough to block small cooling passages, well, that's also a reason for concern.
Anyone else experience any problems with these zincs? My last Volvo was a KAMD44 and though it didn't have any internal zincs, it didn't seem to suffer for the lack of them.
