3 way coolant valve

I'm up here in Efland I would just wait until it fails You can do anything you want proactively maybe it's been replaced already by the last owner who knows they generally tend to go to about 200-250,000 or it's already been placed possibly by mistake before because well whenever happened the coolant control valve generally won't create a whole lot of hullabaloo when it starts to go bad you'll notice some weird things happening in relation to how things are happening but that's about it slow down and get where you're going and change it when you get a minute by the time it cools off you'll be able to drive again for quite a bit until anything really goes on but generally there's no reason to proactively do that.
