Ok, I have a 1994 ford explorer. I filled the cold fill reservoir up, drove it all day and was fine. Checked later that night and cold fill was empty, so I filled it once more. When I started her up today I let her warm up for 10 minutes or so (cold here) backed her out of the garage and put her in park to lock up the house and when I went back coolant was leaking badly! Well I drove her to the gas station to get gas and the pouring stopped?? Could I just have a bad cap causing it not to leak back into the reservoir and spilling out somewhere? It didn't appear to come from the cap. ANY thoughts?? Also the temp gauge read about halfway (un normal for her) Then I turned the heat on and it went back down. After a few minutes it went back up so I turned the heat back off and it's been ok since.
sorry, I forgot to mention, I checked the radiator ( took the cap off) after I got back from the gas station and the radiator was still full. And yes, it was antifreeze it was leaking. Thank you everyone for you'r input!
 
You have a few possible problems with the truck. The first possible problem is that the reservoir tank could have a crack at the overflow or supply hose inlet/outlet. A second possibility is the reservoir bottle itself is cracked somewhere besides the ports. When the truck is wanting coolant its leaking out of one of those ports. A third possibility is that a hose has a crack or hole and running out when engine is wanting coolant. A fourth possibility is the coolant leaking from the radiator fins and the use of UV dye would assist you on finding the crack. A common leaking area the port holes on the water pump. The fifth possibility is the thermostat was stuck closed for a few minutes to cause the leaking and the thermostat reopened after the coolant pressure went back down.
