Description: NOS Mopar 16-LBS Stainless Steel Radiator Cap Part # 3781830 B5 Made in USA Feb 1975 - 48+ Yrs Old Dodge-Chrysler-Plymouth-Jeep Part# 3781830 Center Stamped B5 Build Date Feb 1975 This is a stainless steel radiator cap not zinc plated. This NEW OLD STOCK (NOS) vintage Mopar radiator cap is stamped with the part number 3781830 and the Chrysler "Pentistar" emblem. The center brass rivet is stamped B5 which means the date of manufacture was Feb 1975. The outer edge of the cap says "KEEP TIGHT" with arrow and "DO NOT OPEN HOT". Fits many, many Mopar (Chrysler - Plymouth - Dodge - Jeep) applications with a wide range of years. Please make sure it fits your application before bidding. NOTE: This radiator cap is what is referred to as a "Partial Pressure Cap". On a partial pressure cap, the vent valve in the center of the rubber gasket is NOT spring loaded to close. If you pick-up a partial-pressure cap and shake it a little bit, the vent will flop open. (On a full pressure cap, the vent is spring loaded to stay shut with a light spring.) "For 1974, the radiator cap was changed to a new 16-psi version designed for use with the new coolant recovery system and used part number 3781830. The new style cap did not have ears like the earlier designed caps." - Original Challenger & Barracuda: 1970-1974 By Jim Schild page 119 This is a "New" OEM or NOS Radiator Cap that was made in the USA. It is NOT a reproduction or a Chinese copy. This part comes with NO OEM packaging and here's why: These radiator caps were part of a radiator repair business and inventory that I bought from a guy back in 1989. He worked up in Detroit either for Chrysler or maybe a radiator supplier to Chrysler. I can't remember which. I received them back then in large bulk containers as they never had packaging. So I've had them for over 34 years. I got out of the radiator repair business in the mid '90's. It helped pay for college and taught a lot of patience.
