packick Posted February 7, 2012 Share Posted February 7, 2012 (edited) I just pulled the radiator out of my 55 Century and noticed some numbers on the top of the side that faces forward (opposite side of the hose inlet/outlet). Here is what I think a couple of the numbers mean:Harrison (the maker of the radiator)3133727 (which I assume is the serial number of this particular radiator)Those were easy to decipher. But I also found these numbers:R-2755 BMy assumption is the the "55 B" means the radiator is for a 1955 Buick. I have no idea what the R-27 means, unless it is the model number of the Harrison radiator.Does anyone know how to decipher these numbers? If not, it's not the end of the world. I am just curious.Thanks. Edited February 7, 2012 by packick (see edit history) Link to comment Share on other sites More sharing options...

VickyBlue Posted February 14, 2012 Share Posted February 14, 2012 R27 56 B on my 56 Century too... Link to comment Share on other sites More sharing options...
packick Posted February 14, 2012 Author Share Posted February 14, 2012 OK. So the 55 and 56 are the year car the radiator goes into, and the R27 must be the radiator model? Or does R27 only fit a Century? Does someone with a 55 Special want to share their radiator numbers? The mystery continues. Link to comment Share on other sites More sharing options...

Guest kaycee Posted February 14, 2012 Share Posted February 14, 2012 I wonder if the R27 indicates radiator cap number? kaycee Link to comment Share on other sites More sharing options...
bhambulldog Posted February 14, 2012 Share Posted February 14, 2012 I know that '55 was the first year for 7 lb psi caps. Before were 3 lb psi caps Link to comment Share on other sites More sharing options...
1957buickjim Posted February 14, 2012 Share Posted February 14, 2012 Here's what the master parts book says - 1954/55 Group 1.219;- Core, Radiator; PN 3133727 - All cars with CC (Car Cooling - A/C; DF (Dynaflow) or both. Assuming your car has a Dynaflow transmission in it. If not, the correct radiator should be 3131176 for a manual tranny. 1956 : P/N 3134596 Special with Manual Transmission; P/N 3134597 For all 1956 Buicks with Dynaflow transmissions. Not sure of the R27 designation, perhaps it is the number of rows in the core for build purposes. Hope this helps. Link to comment Share on other sites More sharing options...
