I replaced all the hoses and clamps. I guess I'll just make sure everything is very tight, and keep an eye on it to make sure it isn't leaking any more.

So, I installed a new radiator on my 97 Legacy. Afterwards, both the coolant hose, and the transmission coolant line were leaking. Is there some trick to properly installing hoses that I don't know about? I thought as long as the hose was on, and the clamp was tight, there wouldn't be problems.

I put in a new timing belt. The marks are all lined up, but these marks on the camshaft sprockets that are supposed to be lined up are not lined up. Is this ok? http://coconut.xen.prgmr.com/belt.jpg

My 1997 Legacy had an OBD code P0141 (O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)). I assumed the oxygen sensor was bad, so I went under the car with a multimeter and checked, but the oxygen sensor heater was fine, according to the multimeter. So I reset the code, and the check engine light stayed off for a couple days, but then it came back on, with the same code. What do you think the problem is? I'm wondering if the wire or plug leading to the oxygen sensor is bad, and if I should figure out how to replace the wire. Thanks.
