Default Coolant leak from oil pan?

After changing the cam sensor interrupter magnet, I started the car and there was coolant leaking. It looked like it was coming from the oil pan. I tightened the three bolts closest to the timing cover and it stopped leaking.The oil doesn't seem to have coolant in it. Is there something wrong?

Coolant can leak from a number of places on the front side (passenger end) of the engine and drip down off the pan. Places to look include: water pump weep hole, lower rad hose fitting to water pump, tensioner bracket elbow o-rings, coolant elbow and o-rings, heater hose fittings at tensioner bracket, and lower intake manifold gaskets.

But it stopped leaking after I tightened the bolts on the oil pan.
