I just recently had some overheating issues on my 4wd tacoma and, after replacing the thermostat, water pump and radiator cap, the truck drives fine with just tap water in the coolant system (which i will replace with real coolant after i'm done testing) but, when i check the coolant spillover tank right after driving, i see it mildly boiling. When a head gasket fails, the water pump’s ability to circulate coolant through the system is impaired, resulting in overheating.
