The invention relates to a method for soldering an all-aluminum heat exchanger, particularly a coolant radiator ( 1 ) for motor vehicles with a collecting reservoir ( 2 ) inside of which an additional heat exchanger ( 4 ), particularly a transmission oil cooler is placed. The invention also relates to a heat exchanger produced according to this method. The invention provides that the additinal heat exchanger ( 4 ) is, according to the so-called Nocolok(R) method, firstly soldered separately in a vacuum before being soldered together with the all-aluminum heat exchanger ( 1 ). The additional heat exchanger ( 4 ) is attached to the collecting reservoir ( 2 ) only via connecting sleeves ( 5 ) and soldered nuts ( 7 ).
