Yes it is on the drivers side of the front bumper. On a cold say you can feel the difference in the temp.

You can also hear the coolant gurgling at a low simmer if you put an ear to the driver side wheel well. On some trucks the coolant temp gauge will just rise off the cold mark, key on of course.

The pan won't heat up, because the block heater heats the coolant in the block, not the oil in the block or pan.

It could be that you need to replace the plug on the end of the cord.

Just went through this with my truck. Everything "looked" good but was not working. Ordered a new plug/cord from ed, yanked off the old one and seemed fine but was just old and brittle. Put on the new cord and plug and works perfectly again Just because it looks good, doesn't mean it is. Easy way to tell is at nite when you plug in you will see a "spark" letting you know you have some juice. My old one didn't, now the new one does. Very easy and cheap to replace and 95% probably your issue. If its the heater element itself that goes into the block. That is more involved and requires draining coolant, or if you are fast getting a small coolant bath...lol

This is what I have read.

"They all came with the heater element. "Block Heater" was an option and if ordered then the heater cord was added. If you don't have the cord you will still have the element and only need buy the cord and put it in".

So if there is no cord look for the element. I may be there.

Question I have is when plugging in the BH cord, I get the "spark" but it then trips the GFI outlet my extension cord is plugged into. Have tried different outlets and same for all I tried. Could the plug still be bad even though it does "spark"? '99 f350 272k miles. Thanks, doug
