Raiderdave517 Posted September 20, 2016 Report Share Posted September 20, 2016 Good morning everyone. I own a 96 seville sls, 4.6l. I have had some over heating issues in the recent past and I noticed something odd this morning. I haven driven the car all weekend from Friday at about 6:00 pm until today Tuesday. When I started the car the DIC indicated that the car was already at 77°. Is that normal? If not what should I do first? Link to comment Share on other sites More sharing options...
BodybyFisher Posted September 20, 2016 Report Share Posted September 20, 2016 Well the car's temperature when it cools off will drop to the ambient temps. What is your outside temp? Sounds normal to me.

rockfangd Posted September 21, 2016 Report Share Posted September 21, 2016 sounds normal to me. Your Seville has digital readout for coolant temp? That is a setting that has to be changed to get it.

Cadillac Jim Posted September 21, 2016 Report Share Posted September 21, 2016 The car takes several days to drop to ambient temperature, particularly if it is garaged and not subject to winds. 71 F after resting for a weekend is normal, if it is a few degrees warmer than the garage. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

BodybyFisher Posted September 21, 2016 Report Share Posted September 21, 2016 In addition, if there was a problem with your ECT sensor being out of range, you would set a code. These are the types of codes the ECT could set if the system detected a problem: DTC P0115 Engine Coolant Temperature (ECT) Sensor Circuit DTC P0116 Engine Coolant Temperature (ECT) Sensor Performance DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage DTC P0119 Engine Coolant Temperature Circuit Intermittent Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Raiderdave517 Posted September 22, 2016 Author Report Share Posted September 22, 2016 Thank you for all of your responses. The car sits outside, and the morning that I noticed the temperature reading, it was about 71° outside. Link to comment Share on other sites More sharing options...
Cadillac Jim Posted September 23, 2016 Report Share Posted September 23, 2016 If it sits outside, then it may read the outside temperature after sitting overnight. It's hard to say what it will read, because in the coolest part of the evening just before dawn, the car may cool to the point that it will actually be cooler than the outside temperature by 7:30 AM. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
