Just a thought ive had after deciding to do an oil change on my autobox , my previous autos have been 3.0lt and 2.8 fords ,these have a problem with the oil cooler on the radiator , they tend to leak between the rad and cooler,this as you will know results in a knackered box , so i have always fitted a stand alone oil cooler usually 13 row , what i was wondering is do volvos suffer the same problem , as if i am doing an oil change it would be an ideal time to fit one
