Willys CJ3B Jeep Radiator Cap. CJ3A (Late), CJ5, CJ6, Pickup, Wagon, Jeepster.

CJ3B Radiator Cap, 7lbs,  $8.95

This item is a very high quality new production radiator cap.  For 1 5/8 inch ID filler neck.

Correct for many older jeeps including the Willys CJ3A (Late style / radiator mounted to grill), CJ3B, CJ5 (55-71), CJ6 (55-71), Jeep Commando (67-71).

This cap is not correct for MB, GPW, M38, M38A1 or CJ2A.    Also not correct for early CJ3A (2 1/8 Inch ID filler neck).

If you are not sure if this is correct for your Willys / Jeep measure the inside diameter (I.D.) of the radiator filler neck.  If it measures 1 5/8 inch, this is correct.  If it measures 2 1/8 then this is not correct. 

You will be very pleasantly surprised with the high quality of this item.  I use these caps on my jeeps.  Your jeep’s cooling system will never work correctly until you use a correct and quality radiator cap.
