When do you turn on the grid heater?
When do you turn on the grid heater?
At the time you turn the ignition key to the ON position the PCM / ECM looks at the IAT (Intake Air Temperature) temperature and determines if the manifold is cold enough to need pre-heating. Typically this occurs when temperatures are below 55-65*F.
Why does my car’s grid heater keep coming on?
Driving at low speeds can make the grid heater stay on seemingly endlessly as the cold air is driven into the engine at a high rate with the grids failing to heat it up to the temperature that the grid heater (s) turn back off.
When to use a block or grid heater?
When temperatures are below 0*F it’s suggested to cycle the grid heater twice to help aid in starting. Block Heater use can offset intake temperatures, since the block will warm incoming air. As in anytime you start the vehicle and grid heaters are active it will take longer to recharge the batteries.
How does a grid heater work up a hill?
Basically, you might be going 15mph up a hill and the grid heater will cycle on and instead of turning off the next second like normal, the threshold temp is never met and the grid will stay on for a seemingly endless time. Like I said, the conditions have to be perfect in order for it to do it.

How are the elements of a grid heater determined?
There are 2 grid heater elements. The PCM / ECM will determine if one or both elements will be used. Here are the times and temperatures you should see. When temperatures are below 0*F it’s suggested to cycle the grid heater twice to help aid in starting. Block Heater use can offset intake temperatures, since the block will warm incoming air.
