Clean rebuildable water pump core, CASTING # 400269 PART # 230337 or 230900.

The application is 68 442 with HD cooling AC and automatic.

If these things have a date code I need it to be prior to the 3rd week of Sept 67.

Looks like pn230337 may have been superseded by pn203900 around Feb 73. Part # 230900 should have the same 400269 casting #?

Please reply with price pictures of overall pump and gasket surfaces. Please include delivery to 14623 zip

Ha, you're like me dyslexic. You mean 400296. I didn't see it for sale unless its way back in the classifieds?

I edited my initial post. Looks like these pumps could have either PN but should have the same cast #? The 230337 PN was superseded to 230900 sometime around Feb 73.

Do you know if these castings have dates? If so I need one dated prior to the 3rd week in Sept 67.

Thankx for the replies Junior and 442.

nope. 400269. although it's known to have a poor mold, so can also appear as 296 and 268.

yep, they have julian dates. I don't recall what his is dated. it's only the day, no year though.

Then this chart is wrong? If so we need to let Kurt and Joe about it.

The chart is wrong. It is supposed to be 400269 for '68-'69 model years with heavy duty cooling or A/C. The pump with the date code of 213 that RocketDevo has would work nicely for your build date of the third week of September 1967.

he sold it

Randy this is a Julian date code, right? So August 1st...day 213 of what year??

droldsmorland

Rocket,
Can you decipher the other Letters/Numbers? D2 D1 D4? Day 1 day 2 etc of a given week?

Whats the A on the 213?

What impeller does 213 have?

The 213 as Randy said should work for my O9C build.

Thanks for the follow-up Junior...By the way, GT-37 400 with a stick, poor mans GTO(junior supercar) very cool car! Is that the one I saw in Hemmings MCR?

The "213" or any numbers that appear in that spot on the water pump are the three-digit Julian date. The year wasn't on it so, for the 400269 water pump, that could be either 1967 or 1968. Several parts on the Oldsmobile engine are like that as well.

if it's the one that a Hemmings restoration profile was done on, no. But I did meet them a few years ago. They have the only other 70 GT-37 I've seen in person. Theirs and mine are both cardinal red cars built in Fremont a week apart. They are the original owners, I'm the 5th owner of mine. They have a 350 stick car, mine is the rare 400 stick. As rare as my W-31 is, it's common compared to the GT-37.
Mine has been in some Hemmings Muscle Machines articles on the Pure Stock Drags.

now back to your regularly scheduled wanted ad thread

As others have said, the Julian date is a number of the year, there is no reference to actual year. The "D4" I believe is the day of the week. I do not know what the "A" by itself means, most likely another internal way of tracking the casting process.
All three pumps were rebuilt with the original cast iron impeller.
Thanks
