he has a 2000 model, it's NOT a mazda5
it should not be a big deal to change it out without a manual... usually it can be changed without removing the bumper or taking out the radiator... the radiator does have to be moved out of the way (without disconnecting anything) which gives just enough room to slip the condenser out... it is recommended that 30ml of PAG 46 (ATMOS GU10) oil be added to the new condenser and the o'rings on the hoses replaced during installation... the rest is just evacuating the system and adding refrigerant into the system which is a determined about by mazda (call your dealer to find out if there is not a label on the hood/bonnet
