Engine Block Heater Test.....

[SHOWOFF]

Cold weather is coming up. How do you test to make sure your Engine Block Heater is working? Purchased the truck used 3 months ago and it has the cord installed. I want to know how I test to see if its working or not. Anyone know?

Turn stuff off in the house, look at the speed of the power meter, plug it in, then if the meter looks like its ready for take off, its working.....

Or in all seriousness, plug your sct in ( i assume you have one based on your sig) and look at coolant temp, then plug the heater in and see if it rises slightly. Best to do this at night...

Just plug it in at night, then the next morning start it and turn on your heater and see if it blows warm or cold.... or plug it in for a few hours then feel your oil pan it should be warm.

Plug it in and listen for a faint noise coming from the right side of the engine / fenderwell area. Mine always makes this very low hissing ( not sure if this the best way to describe ) noise.

when you plug it in you will hear the plug "snap" if you hear or see the power (i have a clear plug) its working
