Question about 1997 Pontiac Grand Am
Smalll hose underneath the engine towards the firewall is leaking as it looks like a possible drain outlet. Shaped like a number 7. Currently just water coolant water running right through it. Would like to know if this is a drain plug and what I need to get it repaired.
This L shaped hose is a drainage for the heater core compartment. Once we removed the panel to the heater core it was obvious the heater core was leaking into this compartment. We changed the heater core out and the problem has been solved :)

Hi Oceanfront 98!
The small hose goes to the heater core inside the car. Not being able to see the the piece you describe, I can't tell for certain... it might be a drain, but is more likely a control valve, regulating the amount of coolant directed to the heater.... But whatever it is, the leak needs to be fixed.
The most common problem is a loosened hose clamp --- make sure the clamps are secure, The next most common problem is a crack in the heater hose --- if this is the problem, there is usually enough hose that it can be trimmed back an inch or two (after loosening clamp and removing the hose from its fitting) and reattached and clamped, providing the crack is at the fitting. If there is not enough slack, or if the hose is cracked further downstream, then the hose needs to be replaced. The third possibility is that the drain / valve is leaking itself --- and this would also require replacement.of the faulty part.
A temporary fix can be done by bypassing the heater core and valve --- this is done by connecting a hose directly to the two fittings on the engine where the two hoses from the firewall were connected. This will stop the leak, but you will not have interior heating.
