You first have to figure out if the engine is really overheating or the alarm is not working correctly. Is the water flow out the exhaust normal? If it is and the water temp was really 138F, then the issue is with the alarm circuit. Note that typically the temp gauge is operated by a sender which is variable resistance and the alarm is operated by a temperature switch. The sender and switch are usually separate devices though sometimes combined into a single assembly.
