Hello Everyone! I'm attempting two auto repairs concurrently. One is replacing the battery cables on a 1994 Nissan Sentra GXE 1.6L (manual transmission) in the hopes I won't need to replace the alternator. The other one, which is what this thread is about, is a 1992 Ford Explorer Sport 2WD (automatic transmission). I'm replacing a blown head gasket, and I've gone through this site looking for advice. Another source of information has been the Chilton manual. At this point I'm stuck trying to remove the radiator, and my problem is where the transmission cooling lines are connected to the radiator. I circled the lines. In the manual there is no mention of these and I could be wrong about what they are. My question: how do I disconnect them? They're on real good.
