    I have a nice 2015 Gen 3. Only 70,000 miles (II live on Guam, you can't drive very far without falling in the ocean). Got a check engine light today, code P261b, appears the water pump is failing. Obviously I won't drive it, and will replace the pump. Is there a gasket I need to order, too? Anything tricky about draining and replacing the coolant?

    Worth replacing the thermostat too?

    Doesn't hurt to change the thermostat also.
    Fill S L O W L Y! And you shouldn't have a problem.
