need help with my cressida

Hey guys i just got a 1978 cressida with only 70 thousand miles on it. Basically its in good shape no major dents and minor lower area rust. I need to find some specs on the cars engine. It basically has a cooling problem and major coolant leak. But otherwise shes a sound car. Minus the basic interior due to age. Shes my project but any help or info on these models would be appreciated =)
