I replaced my radiatior on my 92 745t last summer. What a nightmare. Not the job, but getting the correct part. I had 3 different places order the wrong radiator. But they were all the same wrong rad. I had to take the old part to the parts store & they finally got the correct part. It was a nissens aluminum core with plastic tanks. I went to nissen's web site & traced the part backward by number. It came back to a 940 not a 740. Aparrently that is why I kept getting the wrong part.
