Having problems with your 1992 Pontiac Sunbird ?
Water leak right next to inlet hoses for heater core . could there be a drain hole there
It depends where the hole is located and where the leak is coming from. If the leak is clean water - it is probably normal condensation draining from the AC. Some water pumps have a small hole to indicate when the seals are worn out, when that happens "water" or colored coolant will leak out to indicate it is replacement time. Usually this hole is located underneath the pump and behind the belt pulley.
Yes, they typicaly about the same size as a pen. Make sure that it is just water comming out, and not coolant. If water, this is normall from condinsation, if coolant, you will need to change the heater core.
