Abstract
The subject invention provides a coolant cross-over for circulating an engine coolant between a first engine component, e.g., a first cylinder head, and a second engine component, e.g., a second cylinder head. The coolant cross-over defines a first outlet in fluid communication with the first engine component, a second outlet in fluid communication with second engine component, and further defines a passage interconnecting the first outlet and the second outlet. The coolant cross-over comprises a polymer. A sleeve comprises polyaromatic sulfide and is disposed within the passage for separating the engine coolant from the nylon which forms the coolant cross-over to prevent physical, thermal and/or chemical degradation of the polymeric coolant cross-over by the engine coolant.
