Have a Car Question? Ask a Mechanic Online.
Hello. Welcome to Just Answer. Please allow me to assist you. Whilst this is a question specific to a BMW, this is also a general type question where the manufacturer of the vehicle in not critical.
Technically, the 'coolant exploded internally' is not very precise as to what happened. If a hose ruptured, and caused the coolant to be lost, or something impacted the radiator, the coolant would also be lost. This would cause the car to overheat and seize the engine. Changing the oil, sadly, would not cause something to go wrong with the coolant. However, not having enough oil in the car an cause the engine to develop an overheat condition where the coolant hoses could rupture. Rare, but it can happen. The first thing to do is find out how much oil is in the car. Then have the exact cause of the failure described to you in great detail. Just saying "the coolant blew out and you need an engine, Sir" is not a good answer. Can you get that information and get back to me? Thanks
You want to know if the engine is full of oil....If the oil pan drain plug or the oil filter are loose. You want to know exactly what component failed and allowed the coolant to escape the cooling system. A hose, a radiator, the head gasket, block or cylinder head failure, etc. Exactly what caused the coolant to escape. DO not settle for a general answer. You want to know exactly, and no 'maybe this happened, maybe that happened".
ok Please let me know
Legally, if the words "Customer states: Check the cooling system and advise if any issues are present" are not on the repair order, they are not legally bound to anything regarding the cooling system. Again, legally speaking, they were contracted to do an oil change.....Nothing more, unless they put on the repair order, or gave you a check list where additional things were checked and verified as good during the service. If you have this check list, and something that was verified to be OK at the time of the service actually was bad, you have a really good case. Most shops 'top off' the fluids as a courtesy. This is not mandatory during an oil change, but is a good idea that they do it to improve customer satisfaction. If there WAS a problem that they saw, and did not notify you, yes, they were legally bound to tell you the deficiency. If they missed a leaking hose, etc, and did not tell you, they could be found guilty of 'contributory negligence', ie they neglected to address something that would have resulted in a catastrophic failure.
This is where you need a really good lawyer...the negligence aspect.
You are very welcome. I will be here.
That is unacceptable. You can run this car with no coolant in the expansion tank and not have a critical overheat condition. The expansion tank is there just to catch and hold the expansion of the coolant. As the engine warms up, the coolant warms up. Hot coolant expands, and it needs someplace to go. Hence the need for the expansion tank. As the engine cools, the coolant decreases a bit. I am not comfortable with this explanation. Expansion tanks do not 'burst". They are not designed to hold pressure.
First, you need to contact your insurance company and see if you have coverage on this issue. Some policies do include failures like this. If it is covered, the insurance company will pay for the repair, and possibly sue the servicing dealer to obtain the funds they expended to pay for your repair. Tell the insurance company you took the car for service, and it overheated and seized up. Also tell the insurance company exactly what they told you regarding the failure. Perhaps they will cover the replacement costs. If they do, they will probably install a used engine, which brings us to the following point:
Second, if the car does not have coverage, the next most viable option is to locate a good, low mileage engine from the secondary market. There is always cars like yours that are involved in issues that cause the car to be sold for salvage (flood car/vandalism/tree fell on it/hit whilst parked, etc). A good used engine will not cost 17000 dollars to install. Some automotive places that sell used engines will also provide you a guarantee of fitness on their replacement parts. IE they do not sell junk. If this was my daughter's car, I would look into getting her a used engine. I would not spend 17000 dollars on a replacement.
If I had 17000 dollars, it would be on another car.
lastly, you could trade the car in, blown engine, on another car. You will take a big hit on the trade in value with a car with a bad engine. The best route here is get a good used engine.
Possibly. The laws vary from state to state. You best avenue here would be to consult an attorney in your location. If you have evidence that supports they neglected to address an existing issue, you have a really good case. A word of caution here: Do NOT let any further diagnosis or dis assembly occur on the car if you enter legal proceedings. Have the car towed to a place that your lawyer trusts, someone with expert witness credentials.
that is saddening. I would contact your lawyer, and see if you have a viable case. If not, I would look into a used engine replacement
