Hey cal thanks for the pictures. yes I replaced those parts today....unfortuantely when i went to replace the pressure switch with the 2 pigtail wires, i was sprayed in the face by something......mostly air and some grren stuff, but i still replaced them. same thing happened when i replaced the thing on top of the valve...i guess the a/c cutoff switch on top of the cylinder head....hot water/coolant sprayed out everywhere. so i know how to replace the lost coolan/water, but what do i need to do to replenish the stuff that came out of the receiver/dryer?
