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, no sign for full-hot). Then after I drove it to normal temp. 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?

There is no overheating/high temp.

Yes it goes into the system, as long as its on full mark and is not leaking you are oK.

Thanks so much for your help!

So what you are 100% saying is that the coolant gets sucked out of the radiator reservoir and pumped around through the cooling system. Then when the car is cold it flushes back into the reservoir?

Thanks again for your time!

I can't thank you enough. Everywhere else that I asked said I had a leak, I was certain they were wrong. Now that I have an explanation from an expert i'm happy!
