| possible blown head gasket help! The other day im towing a light load and the coolant light came on so i topped it off later on that night and ran it with the cap opened and noticed the coolant resivoir is bubbleing purfusly and with the cap on for a while warming up my upper hose is rock hard. no overheating ever or mixed fluids those are my only symptoms. pretty sure its a head gasket but wanted to see if anyone has had this problem like maybe if a thermostat stuck closed would do that or something i dont know. ANY ADVICE HELPS THANKS!

I wasn't pushing fluid yet. But I had a hard upper hose. One cylinder was blown and three others were starting to blow. If you're up for the challenge then go for it. It's a great way to learn about our trucks.
