So I decide to get my Eldorado out of the garage. It's had a problem with the climate control computer and I've been waiting to find one. In the meantime I rigged the vacuum lines so I have defrost. Anyway, I put it all back together and test drove it. Engine temp rises. No heat. Engine temp drops, heat comes on. Drive it home. Low on coolant. Way low. Open radiator cap, not quite slow enough and make a mess. Coolant looks bad. Like there might be oil in it. Fill radiator and overflow. Test drive. Throw serpentine belt. I guess the coolant may have sprayed more than I thought. Drive 1 mile home. Buy new belt and install. Top off coolant. Temp is now bouncing around more than it used to. I need to test coolant for hydrocarbons. Could have a blown head gasket. There is no evidence of a leak on the garage floor. Did I mention that when I drove my Toreador MK8 to the auto parts store it wouldn't start when I came out? The starter didn't turn. I don't even think I heard a click. After a couple of tries the power was back. This is completely new. Battery connections look good. It had power; the lights, radio, and stuff worked and still did when I turned the key, but the starter didn't turn. It' started fine the next couple of times.
