Just above the water pump on the right side should be a code. The letters are the month A=january L=december the next two digits are the day it was cast the last would be the year A156 = Jan 15th 2006

Re: How do I find date code on 5.3 liter engine ?

Not trying to revive an old thread, but the months are as follows:

A = Jan
B = Feb
C = Mar
D = Apr
E = May
F = Jun
G = Jul
H = Aug
J = Sep
K = Oct
L = Nov
M = Dec

Source: I've got a "M066" date coded LQ4 block. It breaks down to be cast on Dec 6, 2006.
