62 Coolant Supply Tank Sticker

[Michael H.]

Looking for the part number for the sticker that would have been on the coolant supply tank for 62. The part number would be in the 62 AIM.
Also, a brief description if possible.

Thanks.

They readily sell all the decals/stickers thru Corvette Central.

Caution sticker -P/N 3718263

Thanks Donald. That's exactly what I needed.

Interesting that the number is so low, numerically. That range would originally have been used some time in the mid 50's. I would have expected a number closer to 378xxxx for 62.

Michael,

That Caution Sticker (GM 3718263) was first used in the mid-50's. Adams Vol. 1 says it was used on the radiator top (RH side) from late 1956 through 1957 (p. 150), and then brought back again on the expansion tank in 1962 (p. 407 with drawing), but photos show it being used in 1955 (p. 58), 1956 (p. 123-124, you can just see the corner of the sticker) and 1957 (p. 175). There is a close-up of this sticker on either a 1961 or 1962 on p. 350, but it is a repro. The wording conflicts with the drawing on p. 407 ("Cooling System" vs. "Coolant System") and the word "Fahrenheit" is incorrectly spelled "Fahrenhiet" on the repro sticker (sort of like the old "Refrigerent" labels). Since one is a drawing and the other is a repro, with no clear photo close-up of an original, I don't know yet which (if either) wording is exactly correct:

.......CAUTION
THIS COOLANT SYSTEM (or "Cooling System "?)
..
....FAHRENHEIT BY
....GM PERMANENT
...TYPE ANTIFREEZE (should there by a hyphen between "Anti" and "Freeze"?)


The GM 3718263 "Caution Sticker" is called out in the 1957 AIM on Section 13, Sheet 3. It is called out again in the 1962 AIM, Section 11-13, Sheet 5. I don't have any other C1 AIMs to check, but Adams says it's not in the 1961 AIM (p. 351, Vol. 1), and the copy of the relevant page from the '61 AIM does not show it (also p. 351 of Vol. 1).

Close, for the other Caution Label that goes on the Radiator, GM 3764584.


Relevant to midyears, when the small, nearly square GM 3718263 Caution Sticker (ref. previous post, "") was moved to the Expansion Tank in 1962.........................CAUTION

AND IS DESIGNED TO OPERATE ON PERMANENT
TYPE (ETHYLENE GLYCOL BASE) ANTI-FREEZE ONLY.
IF NON-PERMANENT TYPE (METHANOL BASE) IS USED,

(example above shown in Adams Vol. 1, p. 407)

on the radiator in the 63-64 AIMs, but they are discussed here in the archives and in the 63-64JG (p. 130), and they are shown in lots of GM photos and publications from the time.

So even though the second Caution Label is not shown on the radiator in the 63-64 AIMs, that's where it was in the 1962 AIM, and that practice was apparently continued 1963-64. There are early GM photos of 1963 Corvettes with the small nearly square Caution Label on the Expansion tank, and the long rectangular Caution Label on the LH radiator top, just like 1962.
