I recently replaced the glow plugs on a ‘96 Ford F250 pickup with 7.3l Powerstroke engine. This particular vehicle is also equipped with several Banks upgrades. I found some good articles over at powerstroke.org for replacing the glow plugs as well as a source for an entire “kit” from the powerstrokeshop.com to do the job right.
The drivers side was pretty straight forward but the passenger side was an little more complicated because of the inter-cooler piping and the Banks Brake. I started on the drivers side and removed the air inlet pipe housing from the compressor to the air cleaner. I then removed the brackets and bolts holding down the valve cover. There was enough room to remove the valve cover without removing the inter-cooler piping on this side. I then removed the valve cover gasket and the under valve cover harnesses.
I had read several warnings about the glow plugs swelling or becoming carbon encrusted and stuck in the cylinder head during removal. One suggestions was to run some injector cleaner through the system before replacing the glow plugs to clean up the carbon. This truck has been running bio diesel for a while and no problems were encountered during the removal of the plugs. A 10mm thin walled deep socket is needed. The rockers are pretty tight so a thicker wall socket will get stuck.
I replaced the glow plugs with the new Ford ones from the kit, as well as replacing the under valve cover harness and valve cover gasket.
As I said, the passenger side was a little more tricky. I had to remove the inter-cooler piping, the alternator and the Banks Brake mounting bolt closest to the valve cover.
The back bolts on the valve cover near the A/C evaporator are a little hard to reach as well. With that done I was able to squeeze the valve cover out. Again I removed the valve cover gasket, UVCH and glow plugs replacing them all with new. After reinstalling every thing it was time to test. This truck will no longer need to be plugged in, even on moderate days, to start. (more…)
