How can you tell when a heater core needs to be replaced?
Determine whether you’re smelling antifreeze, seeing wetness on the passenger side floor or getting a greasy mist on the interior of the windshield when the defroster mode is on the temperature control panel.

Do you really need an engine block heater?
Starting your car and leaving it to idle for 5-10 minutes does not replace the need for an engine block heater.

Besides, with the planet on fire and all, it’s probably best not to leave your vehicle idling.
What’s the difference between circulating and non circulating engine block heaters?
Inline heaters require some work, as they are spliced into a coolant hose. Circulating models use the existing pump to spread the heated coolant throughout the system. Non-circulating inline heaters are also spliced into a coolant hose, but the heating is restricted to that spot.
Where is the freeze plug on an engine block heater?
