Do 2001 Limited Excursions have a plug for the glow plugs? Also, how many glow plugs do I have?

 

What do you mean by plug for the glow plugs?

You will have 8 glow plugs. One for each cylinder.

 

8 Glow plugs ZD-11. Four on each head. They are located under the valve covers. Each "bank" of glow plugs has a UVC harness (Under valve cover)
CM-4884 (2).

 

Each glow plug has its own "plug" your 7.3 has 8 if you buy the good ones they're around 15$ each. I bought some for 11$ a piece that are good from oreilys. U have to pull the valve covers and your turbo piping on both sides air intake also. But if your not white smoking on start up u don't have a glow plug issue if u are it could be the stancore(spl?) relay located on the top right hand side of the block behind your fuel bowl

 

Oh yeah and while your in there save yourself some headache inspect each "plug" for the under valve cover harness if they are looking a little burnt replace em. Also do a .50 cent mod it will most likely save u a lot of anger an frustration

 

The OP may be asking if the truck has the ability to plug into the wall to warm up the motor in cold weather with the block heater...I know my truck was made in Kentucky and it does have a plug, I use it a lot in the winter!

BUT i think I remember something about trucks built for southern states not having this....seems unlikely to me me, but could be true.

It is usually found in the front bumper on the drivers side. Other people on this site can tell someone how to track it down from the engine block, in case it is just missing the 110v plug

I am getting ready to replace my glowplugs today so I am hoping not to need the block heater as much as I have in the past few years...

 

If it is the block heater you are looking for, it is located on the drivers side. The heater element actually plugs into the oil cooler housing. The rear part where the oil filter threads on. The cord runs from there to the front bumper. It may be stuffed down in the area where your trans cooler sits. They fall down in there from time to time.

 

Hi Ed,
Yes that is what I was talking about just did not know what the correct name is. My truck was a west coast truck originally so I'm not sure if I have it. I will look. Thank you so much!

 

I was told by a pretty good mechanic that if you use the plug in heater a lot. It could cause a buildup internally around the glow plugs and you may have to pull the head to get them out. Anyone heard of that? Perch57

 

I don't see how, it's a heater element that warms the oil down in the pan (I believe). It doesn't get anywhere near the GP's as far as I know, and it is only 1000w, it's not like it cooks anything.

 

get a different mechanic. that one is a failure.

 

im thinkin his "mechanic" is thinking of the non-motorcraft plugs that swell up and break...

 

I have always been under the impression that the block heater element is in the cooling water jacket to warm the coolant up warming the whole block, not just the oil.

 

MRSVEGAN,
I personally just finished changing my GP's only because of the mileage on the truck and I plug my block heater in virtually year round.....I know it may not be necessary, but then you are not using the GP's to heat things up. Mine were virtually new looking with no ohm issues.

 

Your glow plugs still are energized on warm up even if you are plugged in. If your truck has been sitting for a few hours, even in 90 degree heat, they will energize for a 10 second or so period. If it's colder out, they will energize. Maybe not as long, but you'd be surprised just how much they come on. A glow plug LED is an enlightening thing. (Pun intended)
