It comes out from under the dash. Take out the glove boxes, the console, all under the dash dust covers, eleven 7 mm screws on the core cover, run car up on ramps, disconnect the hoses, remove the drain, remove the lower cover, remove the four 1/4" screws on the core and it will almost fall out. Reverse to install the new one.
