Check the zinc anodes; a new zinc anode is 15
mm in length; if a zinc anode is shorter than 7
mm it should be replaced.
Check and replace the zinc anodes as follows:
• Stop the engine.
• Close the sea cock.
• Remove the zinc anodes from the heat\
exchanger housing and the after cooler re-
spectively.
• Replace the (new) zinc anodes and the cop-
per rings.
Use a sealant, for example Loctite® Thread
Sealant with PTFE or LOXEAL® 18-10 Pipe
Sealant.
• Open the sea cock, start the engine and
check for leaks.
