Okay well the title explains it, but I will go into detail. On a 4.6L V8 Cougar there isn't a 'direct' cap to the radiator, the reservoir is the only way to add coolant. Well, before I drove it, it was on full-cold(thats what it says on there). Then after I drove it to normal I looked and my coolant was all out of the reservoir. Does it go into the system this way and then fill back up when its cold or is this something bad?
