heater core swap 1990
My 1990 just got a new heater core this weekend. It would have been a quick and easy job, except that the new core I bought was a different part. I fired up my old '76 Lemans and ran back to O'Reilly to swap it. I took in the leaky one for comparison. He said that my car is actually a 1991. At least that'* what the heater core catalog suggests. The leaky one looked just like the 1991.
How do I determine the build date? What other parts are different from a 1990 to a 1991 LE? Was the guy at O'Reilly just trying to save face because they sold me the wrong part?

He could be trying to save face...
But you will want to look at the vin Number
1G2HX54C3M <---- M is the 10th didget which is 91 model year... L will be 90 Model year...
My 91 SSE has a build of 9/90 and the LE has a build of 10/90

VIN is L, title says 1990. I didn't see the parts manual in the store so it makes me wonder. I like the store, good prices, I seem to get the wrong part about half the time. How do I determine the build date?

The sticker on the driver'* door says May of 1990. I guess that was late enough in the model run to start phasing in the new stuff. I wish I could have used the 1990 one because the lower nipple on the core was angled up slightly. The mechanics at the dealership must have complained that it was too easy to reach this way so they changed it. The other difference was that the 1990 was noticably thicker than the 1991.
Just noticed that the owners manual is for a 1991. All the paperwork says 1990.

Didn't you pay like $120 for yours? Mine was only $40 US. I don't know what the exchange rate is like...
Like I said, I like the store, the prices are usually much better, they have a large warehouse/store in town, and for the most part the staff is reasonably intelligent. I have found them to be the best in my area based on my personal experience with other makes and models of cars over the past 25 years that I have been working on my own vehicles. Getting the wrong part isn't always the fault of the store or parts clerk. Sometimes they are numbered wrong at the point of manufacture, and as is probably the case in my... case Pontiac, in their infinite wisdom saw fit to change heater core styles in the middle of the model year and didn't bother to tell anyone. Or maybe they just ran out of 1990s toward the end and started using 1991s because that was what they had laying there handy. At least the SOB doesn't leak anymore. Now we're having short-sleeve weather

And yes they could have started using the newer stuff party way through the year... The 1991 Bonnevilles are a bit of a marvel... They had most of the newer stuff that the 92 models used... There were also some structural improvements to the 91 unibody as well...
But there were changes between these cars from 1987-1991...
