Does a 1995 dodge ram truck have bleeder valve in the cooling system?

No, a 1995 Dodge Ram truck does not have bleeder valves in the cooling system in the same way some other vehicles might. While there might be a petcock or drain valve at the radiator's lowest point, this is for draining coolant, not bleeding air from the system. Air is typically purged from the 1995 Ram's cooling system through the process of running the engine and allowing the system to pressurize and naturally expel air. Some air might escape through the overflow reservoir.
