Radiator replacement: 1983 300D
Hey, folks. How hard is this job? My radiator has developed a serious leak.
From the Haynes manual, it really doesn't seem all that difficult. (Detach top and bottom hoses, detach fan shroud, remove retaining clips from top, etc.) But I wondered if any of the steps were tricky one a feller got himself in there. Thanks! Glenn

seperating the oil cooler from the rad is slightly tricky remove the upper bolt and bracket, crawl under, loosen the lower bolt, no need to remove it.
gently pull the oil cooler free, then proceed with rad removal. John

Anyone be afraid of putting a decent used radiator in this car? I can get one for $60 plus $15 shipping from a lot about half a state away. New is closer to $300 and up.

Every car represented on this forum has a used radiator.
If it looks good, doesn't show any signs of leakage, or deterioration of the plastic parts-particularly the top nipple, I would not hesitate. In fact I just installed aused radiator from a member on this very forum. It is entirely satisfactory

Radiator removal/replacement is super easy. I would highly recommend having on hand a new drain plug. They almost always break!
And, I just love the color of your car. Especially the interior!!

Just pulled the one in my '82. Maybe two hours ago. Replacing water pump, weather moved in, partially done. I ground down the outside of a 10mm box end wrench to get to the fan bolts. The four that back out of engine, you'll need to rotate engine to access all. Go with vstech, my biggest problem was removing shroud. With auto tranny, you'll need to remove the two lines, on bottom, 19mm.

Can the shroud be removed without removing the fan?

I took the rad out first, then shroud, then fan. I knew I had to remove all, hence the order. The shroud could not be taken completely out of the way, just removed from rad, and hung on fan. You may be able to remove fan first, sure would be eaiser to get shroud out of the way, then again, maybe not.

i replaced my radiator quite easily. its not too much trouble. like said earlier, the hardest part is seperating the oil cooler. i didnt have trouble removing the fan and shroud considering they came out in pieces after i hit a tree

if you work on the bottom, you can do it without removing the shroud, but it ain't easy. I broke down and pulled the fan, then the shroud, then the oil cooler, then the tranny lines with a new rad ready to drop back in, only lost 1/4 quart of fluid!
and I did it all except for the lower oil cooler bolt, from the top! John oh, get a REALLY GOOD 10mm to remove the fan bolts... they are tight! and they strip off easy.
