DD13 Cylinder Head and Cylinder Head Gasket Change
ISSUE
Detroit™ made a cylinder head casting change for DD13 engines to improve cooling in April of
2015 with engine serial number 471927S0336887. The 471932C effective point is
471932C0200669. The oil drain passages on the exhaust side of the cylinder head were
modified. This change also required cup plugs to be installed in the deck of the cylinder head. A
new cylinder head gasket was released with the cylinder head change. See illustrations below.
Figure1. New DD13 Cylinder Head (Left) and New DD13 Cylinder Head Gasket (Right)
REQUIRED ACTION
When making repairs to a DD13 engine with the new cylinder head design, the correct, new
cylinder head gasket must be used. The new cylinder head gasket part number is
A4710161220. This new cylinder head and head gasket can be used on any DD13 engine with
oil drains in the cylinder block that have the same shape as shown above. The new cylinder
head and head gasket cannot be used on earlier cylinder blocks with square oil drains.
PartsPro was updated to reflect these changes. Detroit always recommends using PartsPro
and the latest service documentation when making repairs to Detroit engines.
