| Engine And Engine Cooling problems |
The engine cooler has a know defect that gm has put out service bulletins for. The engine cooler is cracking, mixing oil and antifreeze that is creating a sludge that runs thru the entire system. Gm wants techs to attempt to clean/flush the engine before they approve a new engine to be ordered under warranty. Gm is aware of the problem and there should be a recall out on the problem according to the service manager I spoke with at the dealership my truck is at currently. I was told the expected time frame is up to 3 months for the work to be completed, with no loaner available that is equivalent to the vehicle that went to the shop. The recall is necessary because if the engine has a major failure while driving it could cause an accident, if the vehicle is hauling a heavy trailer that could be detrimental because the truck can haul up to 40,000 gcwr.
The engine oil cooler failed causing engine oil to leak into the coolant system on my 2024 chevy Silverado 3500hd. This requires a full replacement of the coolant system. In addition, excessive sludge buildup inside the motor is caused. This is a known issue with gm for 2024 diesel vehicles. Gm has released a service bulletin but is fighting my local dealership on the required repairs.
At approximately 35,126 miles the oil cooler cracked and flooded my engine cooling system with over 2. 5 gallons of oil causing catastrophic engine failure.
