A car block heater is a little electric heater inside your engine. It keeps the engine block toasty, and its coolants and oil warm. Plugging in your car using the block heater makes it run more smoothly when it's extremely cold. Some block heaters run directly off of the car's fuel or diesel supply.

Asked By: Guruparan Giritharan Date created: May 08, 2022

2-3 hrsI've found a block heater will usually start to make a noticeable difference in as little as an hour, but in your case with weak batteries, I would leave it on for a couple hours before startup and see how that works. 2-3 hrs would be sufficient enough if you were to put it on timer.

Which is better block heater or oil pan heater?

A block heater keeps the coolant from freezing, and makes gas vaporize faster so the engine doesn't run as rich as long before going into closed loop. A circulating heater does the same, but also gives you cabin heat sooner. A pan heater keeps the oil from gelling, so you can run thicker oil in a worn-out engine.
