08 RDX 100,000 mile service
 

I'm looking for info on what to replace and maintenance for 100,000 mile? Advice is appreciated!

Do you have a detailed service history of the car so far? Yes/no to that will help determine what you should consider at 100k.

thanks CSmoney!

About two years ago I got mine, in Canada @208000km.

Thanks to the contributions on this site, at the time also did:
A) All three pressure switches for the automatic transmission were replaced with Acura original parts from dealership. Kept the old ones, search about "Diy – transmission pressure switches replacement", thank you "https://acurazine.com/forums/members/dcmodels-271275/"
B) the water pump, auxiliary s-belt, mechanic assessed belt had not been recently changed.
C) the relay for the air conditioning circuit was also replaced, was a cheap preventive item.
D) CHECKED the valves, and only 2 required adjustment.
E) replaced the power steering tank, has a filter built-in, non removable, best time to do it before completely replacing the power steering fluid.
F) the valve cover gasket had signs of leaking-maybe, no leaking signs ever since.

I chose to add a block heater (little item to help engine start easier around here in winter, so had no problems starting up despite last year reaching a record windchill cold of -37C - coldest since 1938 when temperature recording started here).
Also, could not straighten out the fins on the original intercooler (~85% were bent, blocking the cooling airflow, I gave up after several days of back aching attempts) so happy to have had ETS cooler as replacement, your situation may be different.

Maintenance minder subcode 4?
