Oooh pretty

They are! To bad they don't stay looking like that!

Wait they don't?

They do glow! They job is to heat up the inside of the engine to help it start in cold weather! Because they are exposed to high heat they don't look so pretty after a couple of years!

Yep, and once the engine reaches operating temperature they stay off. If they glowed all the time they'd eventually swell and pop which is bad news. They're no fun to get out once that happens and that's why I always advise going with OEM Motorcraft glow plugs in a 7.3 because the aftermarket ones are always a gamble. Never seen Motorcraft plugs fail but plenty of the cheaper aftermarket jobbies fail and it ends up costing the customer more anyway. OEM's only cost about $90 so why risk cheaping out on it? Way cheaper than they were when the 7.3 came out, they used to be about $100 a pop back then and injectors were about $1000 a piece.. Thank God all that's changed or I wouldn't be able to afford my 7.3 haha!

Aw that stinks :C

It fine! They arn't seen much!

But if i had one i would leave it out of my car and just stare at it....................................................................................................for.......................................................................................ever..............................................................................................and..............................................................................................................................ever.........................................................................................................................................and....................ever

Could be done but try not to burn anything down! They run about 1,000 ^F!

Hey, those aren't supposed to be blue :)

I know but it's a surprisingly appropriate color! :)

I think the last blue thing was 1980

There was a Ford 401 that keeped the Ford blue until the 90's maybe. Might be late 80's. Not much info out their on that engine. My dad had one in a F700 but he sold that truck early 2000's. Kinda sad that engines lost their color and chrome for plastic and black. :'(

What is the f mean?

What the F do you mean? :) Just kidding, in and around 1947-48 Ford decided to split from the car based pickups and make a separate chassis for trucks, the first truck was the F1, later years had the F-1 be a half ton, F-2 3/4 ton and F-3 being a 1 ton. Later in the 50's the F1 became F100/150 then F-2 F250/ F-3 F350, So the F designation has been for Ford Trucks (from F100-F850) and E series are vans. C series was a cabover delivery truck.

I think his inquiry was about my previous post where I said "They run about 1,000 ^F!" In which case the "F" means Fahrenheit. I put that in there because this is the world wide web and 1,000 degrees Fahrenheit is way different that 1,000 degrees Celsius or Kelvin. None the less there is a lot of good information in your post!

So if i touched it it would hurt

Probably not. It might damage nerve endings in which case it wont hurt.
