Yellow Fan upgrade to Black Fan?


(Greg) #1

Looking at slowly renewing my cooling system - I still have the original yellow fan in my 1988 XJS.

I don’t see any cracks. Is this a must replace item ASAP?

Also, I see OEM at about $188, and aftermarket Eurospare for $75. Who makes the OEM? Is Eurospare fan a piece of junk? Quite a big price difference. And my fan clutch seems fine. Re-use?

Thanks

I didn’t see any cracks in mine ,either, until I removed and cleaned it. I figured I would sooner replace it BEFORE it came unglued and changed the appearance of my hood. Your choice!
I replaced my 30 year old clutch with a new Hayden 2747 HD unit Very happy with results. Bought the black fan from one of the usuals. Aftermarket.
Some will tell you to go electric, but the PO just replaced the alternator, so I left well enough alone. Once you get your ECU back, I think you might be tempted to discover the upper RPM limits on your engine… (and so will your yellow fan)

Yup. circa 71, I removed the “lump”: from my 83 XJ about to become a V8. As in the picture, cracks at the hub, but in my car, a lot more. I tossed it, lest it cause someone grief. A back story goes with it. but, I’ve tossed it as well, trusted, Misplaced…

Thanks for the advice. Yeah, it sounds like these yellow fans do eventually go, similar to the Lucas distributor eventually seizing. Is it a heat thing, mileage thing, or age thing? LOL, yeah, testing 6000RPM may test my fan.

It doesn’t seem too hard of a job? Should probably do it while I’m replacing all hoses and thermostats. Glad to know the aftermarket fan is fine, lot of savings there, which will pay for the clutch. May as well replace clutch while it’s apart, I guess. Don’t want to do this job twice. Thanks for the Hayden reference.

According to The Book, the GM Hayden 2747 will fit to the old yellow fan, but not fit with the new black fan? Are there modifications you had to do to black fan?

The blades of the black fan need minor trimming to fit the clutch. (Dremel)
BTW, my fan came from Welsh.
I’ll try to find a photo. (of the trimming)

One fan blade pic- AND, This is what my radiator looked like inside. Same age as yours…

Greg,
I replaced the old white (that turned to yellow with age) cracked engine cooling fan (EAC3265) with a new black 11 bladed fan (EBC4553) a couple of years ago in my wife’s 1990 XJ-S convertible when I cleaned up the engine bay. I reused the original clutch (EAC4751), had no issues, and didn’t have to trim anything.
If you search the archives for “black engine cooling fan EBC4553” you will find a lot of helpful information about what I did and related comments and suggestions from others. Some of which I followed, and others (like replacing the clutch) which I did not follow. :slight_smile:

It’s highly recommended to change the Yellow Fan Greg.
If you plan to take the radiator out, also highly recommended as it will most certainly be like Dave’s picture, it’s very easy, otherwise it can be quite fiddly.

The Black Fan is the same with the Range Rover P38, direct fit and inexpensive.
I got mine a long while ago from Britcar, I don’t remember if it was a Eurospare, but works fine.

Two months ago I changed also the Fan Clutch and put the Hayden 2665 (standard).
The fan fits perfect and no trimming was needed.
I was skeptical about the 2747 (heavy duty), I was afraid it might make a lot of noise.
So far so good with the 2665, albeit summer hasn’t come yet, but it sure moves a lot of air!

Best,
Aristides

So this one needs no altering of fan blades? I think I’d rather do that. HD may be too heavy duty for the cool Seattle climate.

Thanks Paul, I read through your thread from 3 years ago. Apparently Kirby thinks you’re insane? :wink:
