Install location codes are from the manufacturer's guide (LF = left front of block, RR = right rear, etc.); "position" is the element's clock orientation during install.
First: check whether you already have one
In Canada, block heaters are frequently installed at the port, the dealer, or by a previous owner — and then forgotten. Look for a two- or three-prong plug on a black cord near the grille, bumper, or tow hooks, sometimes still zip-tied from the factory. If you find one, test it before winter with our 5-minute multimeter test.
If you need one installed
A frost plug (cartridge) block heater for the Ram 1500 typically runs $40–$120 CAD for the part, plus shop installation. See installation costs in your city — and book in October, before the first cold snap fills every shop calendar in the Prairies.
