There are two heater hoses going through the firewall that connect to the back of the cylinder head & water pump outlet.
First step is to buy the Haynes manual or download the FSM for free at www.xenons130.com/reference

went to the junk yard today got a lot of stuff, including heater core, what a job to get that out, there has to be an eaiser way. got the heater part off the block got tail light. headlight boot, seat belt and a bunch of other goodies. what king of presure should i test the heater core up to? also which is easier the pull the dash and cross bar or ac unit and fan?

The radiator caps are rated at 12-15psi... no need to go above that.
Pull the dash and cross bar. It's easier than contorting your arms and working upside down. And we even have several "dash pulling" write ups.
