FAQ

Will CPP 3313272 fit my 1989-1998 Dodge Ram 5.9L 12V Cummins?

Yes. This kit is designed around the Cummins 3313272-style freeze plug heater and fits 1989-1998 Dodge Ram 2500/3500 trucks equipped with the 5.9L 12-valve Cummins B-series engine. Always confirm your block uses the 2-1/4" freeze plug bore before installation.

How much does this heater help cold starts?

A 750W immersion heater can make a dramatic difference in sub-freezing weather. By pre-warming the coolant and block, the engine spins easier, fuel atomizes better, and you get less white smoke and fewer hard-start events, especially on older 12V trucks with large injectors or high mileage.

Can I run the CPP 3313272 freeze plug heater with other block heaters?

Many customers pair this freeze plug heater with other CPP cooling upgrades, but you should avoid overloading a single household circuit. If you run multiple heaters (block, oil pan, or coolant), split them across separate, properly grounded outlets and follow the amp rating of each device.

How long should I leave the heater plugged in?

In most climates, 2–4 hours before startup is enough to warm the block and coolant. In extremely cold conditions, you can leave it on overnight as long as you use a heavy-duty, outdoor-rated extension cord and a properly grounded 120V outlet.

Do I need to remove the transmission or major components to install this kit?

No. Installation is done at the freeze plug location on the side of the block and typically does not require transmission removal. You will need to drain coolant, access the plug area, and have room to remove the core plug and install the heater element. Some applications may require removing brackets or accessories for better access.
