QuestionHi Rob, I just bought a 96 Eldorado and a few days after its starts giving me warning messages on my dash board, Change Engine Oil, Check Coolant Level, Coolant Engine too hot, Engine Overheating, Vehicle Speed, Idle, and I start noticing the Service Engine Soon lights is on, So I took to a Dealership and have it Lube (engine oil, top-up the coolant) When I came to pick it up the service engine sign is gone, However, after driving it for 10min. all those message start flashing again so as the service engine sign.
I wonder if it something major or just some faulty sensor what causing those. What is the best thing to do? Help for some advise and Thanks for your consideration.
AnswerHi Pedro,
The problem with the check engine light going out, makes the driver think whatever problem caused it to go on is now fixed.
To have all those issues tells me it is a computer problem. When the light comes on, the computer should store an error code(s) that aids in diagnoses of the problem.
The dealer has a scanner that plugs into the OBD II (On Board Diagnostic) port on the lower part of the left side of your dash. The codes will come up telling the tech what the problem is.
Unfortunately, there is not a majic bullet to fix these cars by yourself.
Once the car is scanned and you know what the problem is, you can commonly go to Ebay and get a sevice manual for your car and sometimes the parts for a lot less than Cadillac charges.
Good Luck
Rob
