The 3.0-liter V6 diesel engine has a block heater installed, but many times the dealer does not order the engine block heater cable with the new Ram trucks. If a truck is missing this obvious 3-prong/110 volt AC cable (it should be on the passenger side of the engine underneath the exhaust manifold), Geno’s Garage offers a replacement. The Geno’s Garage block heater cable is an affordable alternative to the expensive Mopar OEM block heater cable and it is easier to install in the tight confines of the engine compartment. MSRP $15.95. (800-755-1715/www.genosgarage.com)
