Just wanted to see what everyone suggests for preventative maintenance on a 140K miles H2 to ensure continued operation.

I have already sealed all roof vent with silicone, replaced the radiator (seeping on left side plastic tank), replaced oil pressure sending unit and the normal maintenance (tranny & gear box flush), tune up, etc.

What other things would everyone recommend?

Thanks in advance!

 

Replace the exhaust manifold bolts with an ARP stud kit.

 

At 140k, I would check the suspension and ignition switch.
