There isn't a fuse for the engine block heater , it is like the heating element
in an electric kettle , as long as it is plugged in and you are not using a timer
or some other device that controls the electricity , then the block heater is on
( assuming that there isn't a break in the block heater cord , which has
happened to me a couple of times , where I've had to put a new " male " end
on the block heater cord ) or something wrong with the heating element
How do I replace the block heater in my 1998 F150 4.6L?
5.4 i believe is a gas engine. gas engines do not have a standard block heater, this would be an extra added by the owner the diesel engines have a block heater, and if it has never been used the cord and plug will be found rolled up between radiator and grill
The fuse block on F150 2004 and later is located behind right front passengers lower kick panel.
block heaters are not standard on f150's. Thus if it was ordered with the option, dealer added or aftermarket installed it may have a block heater. Best way to find out if there is a block heater is to look very closely behind the grill and look for a plug that looks like a male end of an extension cord.
in the block...
No
Usually there is a fuse identification pattern printed on the inside of the fuse block cover. Owner's manual will not say what each fuse is for, it only tells you where to locate the fuse block(s).
Where is located the f150 engine serial number stamped in the block
In most Ford pickups you will find 2, 3/4 rubber pipes about 6" apart coming out the engine side of firewall. One will usually go to water pump or near it on the block, the other will go the rear of the block.
The starter on a 97 Ford F150 4.2 V6 is located on the bottom, left side of the engine. It is bolted directly to the engine's block and receives power from the battery.
I'm not a mechanic / technician but I was looking at fordparts.com and the picture shows ( 3 ) different options . The core plug on the passenger side of the engine block nearest the front ( closest to where the alternator is ) Or you can have two block heaters on the passenger side of the engine block using the front and the center core plug , or it looks like you can have a block heater on the drivers side of the engine at the rear core plug . One thing they all have in common is that the heating element faces UP on a 1991 Ford F-150 351 / 5.8 liter V8
One the engine block on the 302 and 351's
