So I'm going to replace the thermostat and I went online to check out the parts and on the site it asked me what temperature range I wanted. I guess lower is better but I'm really not sure what to get.

How do I decide?

Thanks!

 

The simplest solution is to buy it from the dealership, then you have nothing to worry about. Most people recommend the honda one.

I think it opens up at 180, but am not sure on that.

 

OE should be more around 192 F....or go to the dealer.

 

Back in "the good old days" a lower temp T-stat was a good idea, but now having a different temp can cause the computer controls to go jabber wacky and start throwing CEL codes.
Consider that there is a SB about opening the hood on the ULEV Accords in the winter, and that simple temp change can trip a code.
