Diameter measurement of cap and Chrysler compatibility
This fit perfectly on a 1986 Chrysler LeBaron so would likely work on any Chrysler, Dodge, K-car of the 80s. Exact dimension for this part of inner ring diameter that goes on the reservoir opening is 3.9 cm.

Ajuste perfecto para el depósito o botella de recuperación del anticongelante. El diámetro del tanque de recuperación del anticongelante de la Town Country 2012 donde va el tapón, mide 40.5 milímetros aproximadamente. Y este tapón marca Dorman le quedó perfecto. El material está muy bien, es duro y resistente.
