I have a 2016 RDX AWD and have 100k miles. I mainly drive in town and on longer drives in the mountain areas. I am wondering when I should replace the upper/lower radiator hoses and the thermostat? I am asking here since maybe other members can share their experiences so that I might use the information as a guide. Thanks in advance.

 

Change the coolant when you change the timing belt, but don’t touch the hoses, they easily last more than 15 years. The thermostat can be replaced preventively in the range of 150-200k miles.

 

Ditto. That's how I'd do it.
