I'm gonna finally tackle the coolant expansion tank. It really needs to be changed. My shop mentioned it to me last time I was there. It's the original Volvo and is showing those hairline cracks on the fender side. Anyway, I was wondering if I should change the lower expansion hose as well. It looks to be original in that it has VOLVO stamped on it but appears to be in good condition. Do I leave it alone or change it while I have the tank out? If I do remove the hose, how much coolant comes out of the radiator? Just don't want a big mess. Or should I leave this hose alone?

Bonus question: I know there is the turkey baster method in removing coolant from the expansion tank. But the other day I tried it on a water bottle and it looks like the baster only fills up not even half of the tube. And I noticed that when the bottle was near empty, the baster loses its suction ability and what little water is sucked up quickly falls out of the baster once it breaks the water surface. I was wonder if the siphon method works, using aquarium tubing and sucking on one end to get the coolant flowing out. I'm just afraid I might suck some coolant! Good idea? Yes, no?
