Abstract: By using the coincidence degreetheory, new results on the existence of T-periodic solutions for the Lié nard-type equation with delays
x''+f_1(x)|x'|^2+f_2(t,x(t),x(t-\delta(t))) x'+g(t,x(t-\tau(t)))=p(t)
are obtained, which improve and extend some existing ones in the literature.

Key words: Liénard-type equation, Delays, Periodic solution, Coincidence degree
