It should be on the left or right side of the engine in one of the freezeout plug holes
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
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
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.
heater core hoses not hot
in the block...
No
on bottom side of engine
Where is located the f150 engine serial number stamped in the block
The number 5 engine cylinder is misfiring
supercharge it.. And they wonder why we have global warming.
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.
