I'm in the middle of a radiator change. I have the old one out and am expecting the new one in a couple of days. I ordered some more Volvo coolant and was told by a Volvo dealership that I need 4 O-rings; 2 for the oil supply and return lines and 2 for the transmission fluid supply and return lines. I'm also supposed to need 4 white "spacers," one for each line.

I see the two O-rings for the oil lines and I'll replace them.

I don't know of any O-rings on the transmission lines. Even when I've flushed the transmission fluid, I've never seen an O-ring on that line. Am I correct in thinking there are no O-Rings on the transmission lines or am I not looking hard enough? I looked on the inside of the old radiator and didn't see any either.

And what are these white spacers, I don't see those on any line. Nothing about any of this in the Haynes manual or Bay 13.

I want to get this right. My plan WAS to just reinstall the lines in the new radiator with new retaining clips. It would be nice to see an exploded view.
