I'm having trouble finding a parts supplier to replace the rather unique pressure cap on this 2001 TMD22 heat exchanger. I'm worried there is a leak in the tank at the neck of the pressure cap, but I'd like to start by first replacing the cap and sealing ring...
Any advice?
Here's the parts - it's more than one: https://marinepartseurope.com/en/dealer/mpe/category/marine%20diesel%20engines/product/tmd22a/explodedview/54168814?catalog=7744150&functiongroup=Cooling%20System&img=47008.png&header=Expansion%20Tank
Oops. I was looking at the heat exchanger diagram instead of the expansion tank. Thanks for the quick reply!
