MY caddy over heated. i notice it said check coolant level but i had just put antifreeze in it about a week ago i checked it everything looked fine i drove for about 15 minutes and the temperture would not go down pass 215 eventually it began to go up quickly, then the temp reached 257 and idle engine, engine hot, coolant hot started flashing on my screen as soon as i made it to my house it started smoking when i looked under the hood i see that antifreeze had leaked but i dont know where it came from. i dont think it can be the thermostat because that was replaced about 4 months ago. does anyone know what may be wrong?

This is an 8 cylinder (not Northstar)with 42,000 miles. Since June it has not always been starting on the first try. After jiggling the gear shift, it would start up. Yesterday it would never start. It was towed to the dealer. Once it got there it started right up and again this morning. No faults found on the computer. They are trying other diagnostics. Has anyone else experienced this problem? Any thoughts/suggestions? Thanks.

You dont say what year the deville is....but on my old 93 deville I had that problem...and it turned out to be the alternator. Could that be it..? sometimes it would work and sometimes not...until one day it just gave up the ghost totally.

Replying to: bep (Sep 13, 2007 2:59 pm) Not much idea about starting problem, it could be several things. There is a 'neutral safety switch' located somewhere on the shift mechanism (jiggling the shift) that will only allow the vehicle to start in park or neutral. There is also a brake safety switch that will only allow it to start when your foot is on the brake. If either of these is failing, it could fail to start. A weak battery might not start, but after being juggled around recover enough to start. A positive or negative cable that has corrision might come and go. Intermittent failure in the ignition switch. Lots of things. When it comes and goes (unless it's a weak battery - this could be tested), it's tough to find electrical problems, when it is 'gone'. |

I have a 2002 Deville with North star 4.6L engine and about 80000 miles. The "Check Coolant Level" light stays on even though I have had the water pump replaced and re-checked and I make sure coolant level is correct in reservoir tank. The temperature gage indicates normal temperature during operation, so it not overheating. Just had it checked for a non-related issue and repair shop could not see any error codes or messages. Any ideas what this might be, or what to check?

I hear the coolant level sensor is located inside the reservoir tank. Hopefully one of the experts will chime in on how to check it. Maybe just a loose connection?
