Caddynut Posted September 15, 2007 Report Share Posted September 15, 2007 Well, going against the odds, I put bars stop leak in my coolant in my 92 Seville since my newer waterpump seal had a leak and amazingly...it worked!!!!, but now I get "VERY LOW REFRIGERANT" message even though it is full. I guess that crap did something to the sensor. My question is....WHERE IS IT?? 2008 BMW 328xi 2007 Chrysler Aspen 2001 Cadillac Seville STS 2000 Ford Ranger XLT1998 Mitsubishi Spyder Convertible 1996 Saturn SC-11991 Ford F-1501979 Chevrolet Caprice1968 Ford LTD1965 VW Beetle "Herbie The Love Bug Replica** 1961 VW Beetle Link to comment Share on other sites More sharing options...
Ranger Posted September 16, 2007 Report Share Posted September 16, 2007 Coolant and refrigerant are two completely different and separate systems. You are low on refrigerant (freon). Link to comment Share on other sites More sharing options...
MAC Posted September 16, 2007 Report Share Posted September 16, 2007 If the Seville uses 134a then a can of refrigerant with leak sealer and leak detector might stop the leak. But you should use a pressure gauge so you don't over fill. Link to comment Share on other sites More sharing options...
Caddynut Posted September 16, 2007 Author Report Share Posted September 16, 2007 I am sorry....LONG DAY YESTERDAY. It says I am low on coolant, but the radiator is full. Where is the coolant sensor located? 2008 BMW 328xi 2007 Chrysler Aspen 2001 Cadillac Seville STS 2000 Ford Ranger XLT1998 Mitsubishi Spyder Convertible 1996 Saturn SC-11991 Ford F-1501979 Chevrolet Caprice1968 Ford LTD1965 VW Beetle "Herbie The Love Bug Replica** 1961 VW Beetle Link to comment Share on other sites More sharing options...
Ranger Posted September 16, 2007 Report Share Posted September 16, 2007 The sensor is in the surge tank and is not serviceable. You have to replace the tank. Link to comment Share on other sites More sharing options...
adallak Posted September 16, 2007 Report Share Posted September 16, 2007 I was not able to find low coolant sensor in the FSM. There is only coolant temperature sensor close to thermostat. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

BodybyFisher Posted September 17, 2007 Report Share Posted September 17, 2007 Which car are we talking about the 4.9 does not have a low coolant sensor but the NS does.. Caddynut started by talking about this 92 4.9 AC and I THINK he then began talking about his 01 STS 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...
Caddynut Posted September 18, 2007 Author Report Share Posted September 18, 2007 To clear up the confusion (yours and mine) My message is low refrigerant in the '92. Just checked the code this morning. Like I said before...LONG DAY...not deciphering things to clearly. I am not worried about it since my compressor didn't work this year anyway.... 2008 BMW 328xi 2007 Chrysler Aspen 2001 Cadillac Seville STS 2000 Ford Ranger XLT1998 Mitsubishi Spyder Convertible 1996 Saturn SC-11991 Ford F-1501979 Chevrolet Caprice1968 Ford LTD1965 VW Beetle "Herbie The Love Bug Replica** 1961 VW Beetle Link to comment Share on other sites More sharing options...
