Question about 1997 Plymouth Breeze
If you replaced the cap and thermostat and it's still running hot you either have a bad cap/thermostat (they can be deffective even when new), a blockage somewhere in the sustem, or a worse leak then you think you have.
When the car is running at temperature are the upper and lower hoses hot to the touch and pressurized? If the top is but the bottom isn't then you have a curculation problem. You didn't tell us where it sometimes leaks fluid so I can only assume it ie at the pump, at the t-stat, at the head, or at the hose connections. If you have bad head gaskets the leak won't be to noticeable but could allow enough fluid to leak out causing an over heating condition.
For starters, I would inspect the entire system to make sure the circulation is good and also fix that leak.

The first thing I'd make sure of is that the cooling fan is working properly. When it starts to get hot, pop the hood (with engine running) and make sure the fan is on. If not, it's most likely the temp switch/relay.
If the fan is working ok, have you ever flushed the cooling system? Most people neglect to do this. With a 13 year old car, chances are there are deposits and scale buildup in the radiator. You can buy a flush kit for under $10 at most auto parts stores. Also pick up a bottle of the coolant system cleaner. Directions are included with both the flush kit and the cleaner. Flush it really well, then top it all off with fresh water/antifreeze mixture. Amazingly, this solves many of the overheating problems people experience after they have thrown money at thermostats, caps, etc.
