Where Is the Connection for a 2010 Dodge Ram Engine Block Heater?

The 2010 Ram was just a year removed from a significant redesign.

There are not many things worse on an engine than initially starting it on extremely cold days. Not only are all of the seals harder than usual, but the engine oil becomes thicker and the fuel doe not burn as effectively in a cold combustion chamber. Dodge solved this problem by offering an engine block heater on all 2010 Ram models. This dealer-installed option increases the temperature of the block to help negate the adverse effects of starting its engine when it is very cold. Dodge routed the engine block heater’s connector so it remains out of the way, but is easy to access.

Things You'll Need

• Grounded extension cord
• 110- or 115-volt electrical socket

Instructions

1. Open the Ram’s hood. On the Ram 1500, look between the radiator and the front grille on the passenger side to find the engine block heater’s connector. On the Ram 2500 and 3500, find the engine block heater connector routed through the grille, just above the passenger side tow hook.

2. Pull the engine block heater connector through a gap in the grille, if necessary. Remove the tethered cap from the heater’s plug and plug it into the end of a grounded extension cord -- one that accepts a three-pronged plug.

3. Plug the other end of the extension cord into a grounded, 110- or 115-volt electrical socket.

4. Allow the truck to sit for at least one hour as the engine block heater warms up the engine coolant.

5. Unplug the engine block heater and press the tethered cap back over the plug. Start the Ram’s engine as you normally would.
