How do I replace the block heater in my 1998 F150 4.6L?
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.
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
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
Check out the Google Images and search for '93 Ford F150 heater hose'. you should find it there.
It's the block heater. I had the same problem.
It is nnear where the heater core pipe enters the block. It is where a distributer would have been before EFI.
It is a pain in the neck. It is located under the dash behind the glove compartment and looks like a tiny radiator. Good luck.
How do I locate the heater blend door actuator in a Ford f150 pickup
Im not sure, but why the hell would you want to do this?
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
in the block...
