Duramax Coolant Temp Gauge Not Working June 06, 2018, 11:21:13 am Yahoo Message Number: 16694Good Morning, All-I own a 2005 Gulfstream Endura 3640 with the 6.6 LLY Duramax Engine with no mods. My OEM Coolant Temp Gauge does not work however my Scan Gauge does show the correct coolant temp and my truck runs fine. Can anyone tell me if the OEM Gauge has its own sensor and can you direct me to the sensor location?Any information would be greatly appreciated. Thanks, Vern Quote Selected

Same issue as you are experiencing with the sensor working but the dash gauge displaying random temps.GregOn Wednesday, June 6, 2018 10:34 AM, "mnsprk47 mnsprk47@...
