Default Leaking coolant after I put in new injectors!

I put bosch remans in my lb7 yesterday and now I am leaking coolant. The puddle appears to be on the drivers side, towards the front, slightly towards the middle. I am getting about a silver dollar sized amount every two hours. I am hoping that someone can give me some ideas as to where I need to look first. Thanks for all of the help!

Any discoleration in oil ?
T-stat ?
Not too sure whats on that side .. check hoses .... pressureize the system and start looking around .. bound to be something small ...
