Howdy gang. I posted this in the A/C-Cooling category and I've had little to no hits. The /6 portion of the site has always been incredibly helpful so here I am.

The car is a '74 Duster, 3.7L 225. My stock radiator has the CCEGR control valve, but is in rough shape. I'm looking for a new one, but Google is confusing it for the actual EGR. My first question is this:

1. Is there a good lead for this particular part? Someone mentioned going to a Dodge dealer (but I don't trust dealerships for more than one good reason). I would rather order online.

2. I plan on installing an intake from a late 60's slant setup. The EGR, which is linked to the CCEGR, is not featured on that year model intake. How would I go about bypassing the CCEGR and is it wise to even do so?

Thanks for the help. If I need to post a picture of the valve in question, I'll do so tonight when I get my hands on it.
 
First question. Do you have emission inspection in your area? If you do, you might have a problem if you bypass the EGR system.

In the state of Texas, all emissions are welcome. Lol
 
Pipe plug.
Many replacement radiators come new in the box that way because not all cars that a particular radiator will fit had this. Can't remember if 3/8 or 1/2 NPT
I'd rather go with a brass one over iron.

I was thinking the same thing, but leave it to me to assume its okay and destroy my vehicle somehow. Lol Thank you for the reply! In the meantime, though, I plan on leaving the EGR on the stock manifold and stock radiator. Any idea on where to find the CCEGR?

Generically, it is referred to as a thermal vacuum switch/control valve. Try searching for that & see if You get any hits associated with Your model & year. If a part number were visable, that'd be a 1st-search. If I find a part# later, I'll post it, if nobody beats Me to it.
 
Go to eBay and search for 3837622 and pick the one that looks like yours.
 
Here is what I'm working with. I have had little to no luck finding this exact replacement, although I am fine with getting something that looks different, but with the same use and result. My only issue is that I have no idea what this little job does, nor do I know what to look for. They all seem so different. Thanks again for all of your help.

I take it I would need to plug one of those ports?

Why? install the correct valve, and connect the vacuum lines per the factory diagram, if you keep the egr valve on the engine. If not keeping the egr valve, don't even bother with the temp switching valve. Go to mymopar.com and download the proper part and service manuals.
 
The EGR system actually has benefits on a stock or near stock engine. It cools the combustion process and can pick up mileage a tad. It also helps fight detonation.

Because the original has two ports. The one you sent (thanks, by the way) has three. I only have two hoses available to run. I don't want to lose pressure. I have the proper manuals.

That's what I read. My intake, as it sits, is in pretty poor shape. The intake I was able to pick up on the cheap was in much better shape, it just doesn't feature an EGR attachment.
 
You really should purchase a 1974 Dodge or Plymouth chassis service manual. They are usually found on eBay for $25 to $50 dollars. The manual explains how it works and the testing procedures. The valve in your photo is the one installed on the factory assembly line. Replacement valves from Chrysler or aftermarket companies have a slightly different design, but will work.

If that's the intake you plan to run, then simply eliminate the entire EGR system. That's what I would do.

It prevents the EGR valve from operating until the engine reaches a specified temperature.
