Industrial 12339486 Engine Temperature Transmitter

The AM General 12339486 Engine Temperature Transmitter is a coolant temperature sending unit that measures engine coolant temperature and transmits a signal to the dashboard gauge in military vehicle engine monitoring systems. Designed for AM General HMMWV M998 series and Hummer H1 with 6.2L and 6.5L diesel engines, it operates on 24 VDC and uses a 3/8 in NPT thread with a threaded engine/coolant passage mounting to integrate into the cooling system. The device implements a variable resistance temperature sender principle, uses engine coolant as the sensing medium, and carries alternate part number 5569626 and NSN 6620-01-194-6586. Common replacements include AM General 5569626 Engine Temperature Sender, TS6058, and TS6059.
