Question about 1998 Ford Mustang
Is coming from top of engine
If you have coolant leaking from the top of your engine then you have either a bad hose or your thermostat housing is leaking and requires a new gasket. Either one is an easy fix for anyone with even basic mechanical knowledge. Just ask your local parts shop to point out the problem to you.

SOURCE: 1998 mustang gt coolant leak
I just had the same problem. Ford design the intake manifold with plastic water crossover which cracks. The coolant will leak onto the top of the block and and then down the back of the engine. This intake design is a known defect and was ocvered under by Ford for 7 years past the date of mfg. The crack either is in the crossover or the thermostat housing. I happed on this when I found the same leak and traced it back to the thermostat housing. I changed the thermostat, but it leaked worse. You can pickup a aftermarket for $200 and it's about 4-6 hr job to replace.

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck
