Heater core?

yes the heater core is blown you can bypass the heater core on these vehicles fairly easily find the two hoses going from the motor to the firewall unhook them from the firewall get a radiator flush kit from walmart or any other place autozone advance etc. use the corresponding tube size and clamp the two together this will work to get you where you need to go you will not have heat in the vehicle but its summer this buys you time because the heater core on that car is difficult to get out not impossible mind you difficult the part is cheap as things go the labor will kill you in cost you may want to try it yourself get a haynes manual from the parts store read through the section on the heater core twice take a deep breath and go for it.....oh after you bypass the heater core check the system for excessive preassure when first cranked because usually they dont just go out also it probably time for an intake manifold gasket they will use water these cars are super easy to work on up top with a manual parts are affordable let me know if I can help further
