The car is the 2014-2019 CTS models. its a 2.0l Turbo. recently I seen the temperature guage elevating, almost to the redzone. I immediately pulled over and shutdown the engine.
affer looking under the hood. I saw the coolant tank bubbling like crazy, lower tank empty and the fan wasn't on. What is going on. Everything running hot! why the fan isn't on, and i see no leaks!
Update:
1.)The bubbling was because the coolant system needed burping. (Run car with coolant cap off then reput cap on)*Don't if the car is hot, wait for it to cool down!!*
2.)Coolant empty or low, found a hose leaking right at the connection. mines was upper hose that connects engine and coolant. *Used pressure test*
3.)and the biggest issue Overall *Overheating* with Fan not running. Somehow, someway, somebody, i think, had to change my Fan timing that tells it to come on. Found the fan was coming on around 250° when factory recommends 190°. making it nearly impossible for the fan to come at such a temperature, car will be overheating by that time. Luckily the mechanic had a computerized tool that could change the timing. Now it runs when it suppose to and car isn't overheating!!Wow
Had Stealership quote me for a new engine at 10k dollars. LMAO. ppl stay away from crooks please. If you know you been Maintaining and regularly Maintenancing your car, then the car should not be failing on you especially major components that cost a fortune. Beware!
UPDATE Year Later: The mechanic fix did not last. luckily i found a Cadillac Dealership that had just built and moved into town. The people working there takes pride in Cadillac cars and will get to the root of the problem unlike other Dealers i encountered.
The Bubbling was caused by Coolant Hoses that had very tiny cracks, so small most mechanics will miss them. The fan had wore out. Dealer Replaced Fan and Hoses, my car now runs like new and this is over a year now.
Got to find the right people/Dealership. Trust your gut, most out here is a ripoff. But Good people/businesses do exsist.
Hope this helps others!
Thanks and Happy New Year!
