This part apparently works with the cooling/heating system, the part has become caroded and is leaking anti freeze, would like to fix the problem, but am unable to locate the part number and auto part stores are unable to help.

The most common cause is that the system has leaked the freon out. If this is the case, the leak must be located and repaired. It can be anywhere in the system, but more commonly at the compressor seals, the service port valves and O-rings in the fittings for the tubes and hoses. It could also be the condenser or the evaporator leaking.
Other causes would include a malfunctioning control head inside the car, a malfunctioning air-blend door, a burned-up compressor clutch, or bad (shorted or open) wiring in the system.
Inoperative radiator cooling fans can also cause the A/C to not cool.
To put it real simple...it needs to be properly diagnosed to avoid wasting money "guessing" what the problem could be.
Did you replace the thermostat? If not replace it and then have a pressure test run on the cooling system. Also make sure the fan is coming on when it should. If you are loosing coolant with no apparent leak and see white smoke out the exhaust then suspect a blown head gasket.
You may have a cracked head, block or blown head gasket that is leaking combustion gas into the cooling system. If you dont have a combution leak detector kit you can take it to a trusted mechanic tell them the problems you've had and the parts you've replaced. Ask them to check for a combustion leak in the cooling system. A minor combustion leak in the cooling system can sometimes mimic the symptoms of overheating.
Some vehicles have sensors that can control the electric fan with the ignition off to keep the heat buildup that naturally occurs right after turning off the engine.
This can prevent hard starting that can happen with a hot engine.
If it is doing this an abnormal amount, the sensor that is operable with the ignition off may be failing.
Before turning off the ignition, check to see if the engine temperature is pushing the 'red zone;' if it is, then the fan operation may be normal but your engine may be running hot.
Hi dakota_love what we need to verify is if your cooling fan is operating properly, what you need to do is first bring temperature close to redline
(but don't hit redline it may cause a blown head gasket) than you need to open up the hood with the engine running (and temperature close to redline)at and see if any of the cooling fan in front of the radiator is coming on, please update once this part of diag. is completed so we know which way to direct for further diagnostic.
There could be an obstruction in the heater core under the dashboard. It's also possible your thermostat is stuck in the open position. I'd start with changing the thermostat. As far as your A/C goes, either you have a slow refrigerant leak and whomever did the servicing didn't bother to check for leaks and/or the A/C compressor could be malfunctioning. Unfortunately A/C problems can be costly.
