A method for dispensing temperature-automotive body sealant includes providing a dispensing system having a pump operable to pump the sealant and a manifold receiving the sealant and operable to temperature-adjust the sealant has an elongated central body and elongated passages extending from the first end to the second end. First and second end caps are detachably connected to ends of the central body. A thermal unit is in thermal communication with the elongated central body and operable to heat or cool the elongated central body. A dispenser is in fluid communication with the manifold and operable to dispense the temperature-adjusted sealant. Sealant is pumped through the manifold and heated or cooled so as to provide a temperature-adjusted sealant. The temperature-adjusted sealant is dispensed from the dispenser.
