 Hi  well it is under the dash on the passenger side in back of the glove box. To remove it is a pain. You must remove the heater hoses than remove all of the bolts that hold the heater core in and the glove box . than it will come out with some effort. Why do you think it is bad, if it is not leaking it should be ok.
