Pair your element with a fresh cord and inspect coolant condition for best results.

Frequently Asked Questions

Which block heater element fits my 1989–1993 5.9L Cummins?

Most first-gen trucks use the Cummins 3916127 element. Verify your VIN/engine tag and model year before purchase.

Do I need a new cord with a new element?

It’s good practice. Heat cycles and weathering can degrade cords; replace if the insulation is brittle or plugs show corrosion.

Will a block heater help batteries and starters?

Yes. Pre-warming the block reduces cranking effort, improving cold-start reliability and extending battery and starter life.

Where can I find related cooling parts for my 1989–1993?
