Am I wrong?,were both used?
I bought ones from Ames for the 73,.....481776 but with white markings very similar to the yellow marked one you show,it looks correct but not exactly like yours.

481776 is the part# that my GM parts book lists as all 71-75 f body. My book is dated 1978 so it could have changed sometime in that time. I also think that the 481776 is still avalible from GM.


I also show that the 480200 is still a good part#

418776 was dicontinued by GM in 2002.
The pic of the 73 SD has a hose #489876,which is actually the hose on my 79 and is correct for a 79 W72,I confirmed this.
That's why I am curiouse about the 489876 on a 73 SD..........

..........from what I understand 480200 IS STILL AVAILABLE from GM,,,,,

But what about 481776? If it was discontiued in 2002 somebody should tell GM parts Direct because they still show it. I have found there listing to be very accurate. Could they be 6 years behind?

Well,we know GM has been a bunch of bone heads lately not listening to their loyal few left don't we?...........IE no F'n TA in 09,just Craparo
I called Marquardt Pontiac and Jenning Chevrolet....yeah i know,but they "did" carry Pontiac parts,and they told me first yeah,it's available,then a pause.......uh..sorry,it was discontinued
YO told me they were dicontinued in 02.


HOWEVER...........I was told by an unnamed sourcethat 418776 is the replace ment number to 489876.................
....however you have to cut off the #418776 when putting it on...

..... THE PLOT THICKENS

[165th]

Fatherandson, regarding the '73SD, it's an 18K mile car, very correct, and no reason to believe it's not an original hose. I specifically questioned the owner about the hose as I then used it as a go-by for the Brewster car.

Here's a GM 481776 hose. It is longer on the radiator side, but can be cut and still retain the stamp. The GM lettering is not the same as 'back in the day'. I quickly stamped a 489867 on it for comparison sake.

If that number changed, it changed before 1978 because that is the date of my parts book. As I said earlier the 418776 is listed for ALL F from 71 to 75. My book ends with the 75 model year

[165th]

This may be really oversimplifying things, and of course, it's based the data collected for, well, two days and 3 cars, haha, but it appears there are 3 generations of 489867:

1. '73 thereabouts, like the one I made the stamp of, yellow lettering.
2. '77 thereabouts, with RADIATOR spelled out, but the arrow shorter and the triangle moved, white lettering.
3. '79 thereabouts, with RAD and arrow longer again.

And, it seems it would be easy enough to verify the correct part no. for early cars to see some 418776 on original cars.

[165th]

I forgot I had this picture. Here is the top radiator hose from a Scott Tieman restored '73SD Formula. This car has been seen on calendars and Hemmings Muscle etc. It appears to be a NOS hose he used on the restoration, or possibly the original hose.

This picture and the Red '73SD TA were taken at the 2006 TA Nat's. Scott had just finished the car.

I was having a little fun with the 3rd pic. How often can you get a pic of a Brewster Green SD Formula in the dog dish of a Florentine Red SD Formula?

[1977blackta]

Yes, GM 481776 IS still available and also GM 480200 (lower hose). I ordered both a couple weeks ago.

I think that is correct though, you will have to cut the length on the top hose. I will have to look at mine next time I am in the garage. It is at my parents house across town. Doing a major detail job.

Mine is a 77 400 W72 manual transmission.

Really?
Mid telling us where you bought it from,cause i called two dealers and five resto places.
All told me it was not available and discontinued.............

[Norwood]

Duane, http://gmpartsdirect.com/ order them up....and order me belts,9433749 and 9433751 Thanks

[1977blackta]

I work at a GM dealer. I bought it there.

Make sure you have your number correct. I saw in an earlier post you had the number listed as "418776" instead of the correct number "481776".

Part number 418776 probably WAS discontinued in 1992 if that is the number you gave the dealer. Tell them the correct number "481776".

If you did give then the correct number, then go to another dealer because they are not being very supportive in my opinion.

Good luck to you,
-Doug

PS... likewise, as Norwood says, try GMPARTSDIRECT.com Another great source!

I've been looking over the pictures everyone has posted, and been studying the numbers associated with the yellow 76EX50 that is also marked on the hoses. There is a number after the 76EX50 that I'm convinced is a date code for manufacture of the hose.

My upper hose has: 76EX50 8M04 - December 4, 1978 (In this type of datecoding, sometimes the letter I is skipped).
My Lower hose has: 9B06 - February 6, 1979
Build date on my car is February 21, 1979

FatherandSon has 8K24 - November 24, 1978
Do you happen to know the build date of your '79TA?

Coolbird has 6K28 - November 28, 1976
Do you happen to know the build date of your '77TA?

Even Norwood's NOS hoses have codes that could be interpreted as date codes:
5L18 - November 18, 1975
5F02 - February 02, 1975

Finally, there are other letters after the datecode that I don't have an explanation for.
Thanks!

165th,

Wouldn't the 5F02 hose be June 02, 1975?

Just making sure I am reading correctly!

[165th]

Yes Black, you got it right.

Also, the K in Fatherandson and Coolbird should be October, not November.

I think I sent that email out too early this morning!

Yes, I know how mornings can be all too well!

165th,

Father&Son73T/A was asking about this in another thread so I thought I would add info here. I believe my '74 Formula has the correct (original) upper hose (pictures posted). As you can see from this and the original 73SD hose you posted earlier, the date coding was more traditional (6 xx 3 on your picture. 9 19 3 (built 10A) on mine).

I would agree with your curiosity about the yellow 489876 on the 73 Formula. I saw another restoration done by the same guy on a 1970 RA IV where he put a yellow stamping when I know without a doubt that 1970's had a white 480203top and 480201 bottom stampings. SO just because it is a nice restored rare car doesn't verify it is correct,could be.might very well be ....but I would want verification elsewhere besides just that car.like a GM book...or a verified original car. any 73 Firebird would do.. ..
