    Default 302 CFI EGR cooler, later design

    When I did a search I found scant mention of this unit and it's apparently uncommon. So in case the information helps anyone, here's what I can piece together for posterity.

    302 CFI cars from '83-'85 were fitted with an EGR cooler that was teed in to the heater hose. I found that my '85 has the cooler, but not with ports for coolant lines. This is it:

    Looks to be about the same shape and size as the original design, but without the ports. The part number on this one is E7PE-1H464-AA, which I can't find a single reference to anywhere. There's one on eBay with the part number E7PZ-9F464-AA that looks the same, and is what the Master Parts List shows. There was a TSB for this, 87-1-15, but after looking around all I could find was the cars it applied to (everything with a 302 CFI) and not the details of the problem/solution.

    My car has a Ford "Authorized Modifications" decal on the fan shroud which I've always wondered about; quite probable that it was for this.

    The revised cooler has a baffle inside with a screen on each side of it. I'd surmise that the screens are there to collect debris before it gets to the EGR valve. Mine didn't appear to be plugged, although I did clean enough carbon out of it. (The port in my throttle body spacer was completely blocked, however.) Some companies made an EGR gasket with a screen for likely the same reason.

    I know some people omit these, but I didn't see any harm in leaving it in and it was certainly less risky than trying to get the studs out of the TB spacer.

    For your amusement, here's what the Ford shop manual said about the original design: "The 9F464 is quite rugged, 100 percent tested, and virtually trouble-free."

    I vaguely recall reading something about this years ago. The problem was basically that cookies got stuck in the stock cooler and would jam up the valve. The TSB (pretty sure it was a TSB) basically said the fix was to remove it, or maybe it was to remove the cooler hoses to it. Either way you did something to the cooler and it was supposed to quit making carbon cookies that jammed up the EGR valve.

    Is that what that is? That went right into the dumpster doing a carb conversion on my 84, along with 150lbs of other junk they hung on these motors.

    Mmmm, cookies. Interesting bit though that is. I'd likely do the same thing as Jeff though if i had CFI, or just put a coyote in it.

    A carb swap has crossed my mind, but keeping the CFI functioning well enough to run the car is less work. (That, and if I'm going to go to the trouble of a carb swap I'd do a 4-barrel, which is more work...)

    The EGR valve on my car had only a film of carbon on it and seems to work properly, so if that's what the redesigned cooler was supposed to do it seems to have worked.
