Hello. I have a 2006 dodge durango,4.7 liter. I drove it for five miles and the temperature gauge shot up. Got it home and it started spewing coolant. It's coming from the casing behind the thermostat housing. Not sure what part it is or what caused it to leak. It's on the passenger side of engine. Has a pulley on it. Seemed to be pouring out of the gasket there. It's my daily driver. Any help would be greatly appreciated. Thanks
