About 99k miles so coolant change is needed. Question: where is the plastic heater hose connection that fails located. I assume on firewall, but not sure. Part number or official description would be great.
anything else I should know about coolant change?
thanks

 

Passenger side. Between the back of the engine and firewall. Take the engine cover off and grab a flashlight to get a clear view.
