A water manifold routes or combines coolant lines within the engine cooling system. Even when two parts look similar, their connection points and OEM references may differ.
AFES water manifold references
AFES product data includes references such as YC1Q 8K520 AA, 4C1Q 8K520 AA, 6C1Q 8K520 AB and BK3Q 8K520 B2B. The search system matches these codes regardless of spaces and hyphens.
What data is needed for correct selection?
The Transit generation, engine, power output and production year should be checked together with the OEM reference. Commercial vehicle families can contain different cooling circuit revisions within the same body generation.
Verification before installation
The application table on each product page provides an initial match. Final compatibility should be technically confirmed using VIN/chassis data and the connection layout of the installed part.
