Engine Serial Number location and Coolant?
OK, I have been turned on by all the engine coolant flushing and bypass filters, etc..... Its a project I want to try and I have Gooches, WoodnThings and SpringerBobs writeups. I have 130k and I am sure its never been done so it is time. What I am not sure about is.....
I see a lot about using ELC coolant depending on the engine serial number, where can I find this. I have a F350 2000. I suspect the local Napa store carries a good ELC, with the upper radiator hose that goes around belt, etc... I read that the sn# determines which ELC I can use if at all.
Does it seem like a DIY process, then having to dispose of it versus a mechanic doing this?
Thanks again for the help, I love this forum and all these inexpensive projects for peace of mind. Although I am too nervous to do the .50 cent mod because I don't know what to remove to get to valve covers. Or the gas tank mods because I am too nervous (self imposed because you guys have always helped here).
I read a good article on reverse lights but the pictures didn't show up, does anyone have the actual wiring diagram? I like the idea of how bearhunter had it wired up.

Early '99 and older need to stick with a traditional "green" coolant.
You have a MY 2000 rig so you're fine.

To answer your question though, here's the info:
The following information from Gooch pertains to why ELC's are not recommended for use in early '99 7.3L PSD's.
-------------------------------------------------------------------------------------------------------------------------------
Mostly it's the injector cups. International, who made the engine, found some compatibility issues with the older injector cup material, sensors, front cover, seals, gaskets, o-rings, and probably some other stuff when using coolants that contained organic acid technology (OAT). Coolants like ELC's (usually Red) and G-05 (usually Gold) will have these OAT's. Conventional coolants (usually Green) will not.
So International revised those components on all 2/2/99-up build engines (SN 940614-up), and began recommending and factory filling with HD ELC coolants mid-year 2000. Never looked back.
You could use HD ELC's in the older engines, but you run the risk of having to replace the cups and maybe some other stuff. I always try to recommend conventional coolant meeting ASTM D4985 with SCA or a pre-charged conventional coolant meeting ASTM D6210 for those. But it's your call, and some owners use the ELC in their older engine successfully. For the 2/2/99-up builds I would highly recommend upgrading to HD ELC.
BTW, if you need to check the build date of your engine, you can find it on the valve-cover tag (driver's side), or stamped on a machined surface on the underside of the engine, behind the oil filter and just ahead of the bell-housing cover. You may need to wire brush/clean it to read it.

What do you mean I have your 2000 rig? LOL... oh, you mean you have one just like it. 
I thought I purchased this from you or something.
I noticed the coolant looks green, but is very dirty "ish".
I noticed that info, thank you, what always confuses me is late 99, where is the cutoff and its a 2000 with a late 99 motor, etc.... but I get your point, thank you.

You have a model year 2000, no where close to an early '99 MY rig so you're good to go.

The engine S/N is located right behind the oil filter housing. It is a machined surface on the block. You should be able to read it there pending any corrosion. The vertical number is what contains the S/N as shown. The horizontal number is the last digits of the VIN, so you can verify the VIN to the block if you can read it.
You can easily do the fifty-cent mod. Pulling the valve covers is no big deal. Just remove the IC pipes and you will see the path.
If I were you, I would not worry about ELC. It is good for long term, but can be expensive and unless you run a ton of miles, may be a waste. The Gold coolant works pretty well and also lasts 50-100k. Just an option for you.
