2002 Town and Country losing coolant
 

I need help trying to figure out where my coolant is going. I drive the van and when I stop at a light I see steam and a little blue smoke coming out from under hood. When I look under hood, I see a small wet spot by oil pan where the coolant tube is and oil pan has a little wetness on it as well. I also have a small spot of coolant that appears on a engine bracket near the thermostat as well. Engine temp goes halfway up but doesn't overheat. I thought it was a head gasket at first but now I'm not sure. Not sure which way to go on this and I can't afford to pay a garage right now. Any suggestions would be appreciated. Thanks.

best bet is to put a pressure tester on it and look for the leaks no one online can help with a leak location.

Oddly enough I replaced the radiator cap and the leaks stopped. Is it possible the engine was building up too much pressure and the cap was not allowing it to vent? Still need to have system pressure checked. Thanks.
