Meg, According to the FSM for your car the radiator cap should be rated from 14 to 16 pounds, depending on whether or not the car has air conditioning. http://www.imperialclub.com/Yr/1963/FSM/Group07/Page01.htm The parts list for the 63 shows the radiator part number to be 2524991. http://www.imperialclub.com/Yr/1963/FSM/Group07/Page01.htm That doesn't mean the radiator currently in the car is not capable of doing the job. But if it's old and leaking it should be repaired. Personally, I'm not one for patching or repair in old radiators. I just spent $300 to have the radiator for my 68 LeBaron completely rebuilt. To me it's well worth the investment to insure a cool running and trouble free ride.

I want to thank each of you for the warm welcome to the club. I figured I might as well take advantage now with a few quick questions. Honestly nobody knows what an Imperial is, let alone how to work on one...so this is actually my best bet. About a month ago I bought I new radiator cap (13lb.) for my '63 Custom 2-dr. and about a month ago the seam on the top of my radiator developed a couple splits in the seam. When I took it to the radiator guy he told me he thought that I poundage was too much. From what I gather reading old messages on the site, 13 is correct. I don't know if the radiator is original or not, or if that even makes a difference. I do know that it has 2276855 stamped on the top left with DP AC and on the top right it instructs on using Mopar fluids. If anyone CD can let me know if I should indeed keep the 13lb. cap and just have the top reseamed, or basically any information to help me would be fantastic. Thanks again ahead of time~ *Meg* (and Ms. Pearl) ________________________________________________________________________ FREE for 30 Days! - Holiday eCards from AmericanGreetings.com http://track.juno.com/s/lc?s=197335&u=http://www.americangreetings.com/index .pd?c=uol5637 ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
