You ran it hot. You could have head gasket trouble, scarred cylinder, warped compression piston rings are all of the above. Better check your blinker fluid too.

Hi
If you drove your car further than just pulling over and stopping after the fan broke you could have done serious damage.
An over heated engine has the potential for many problems but the most common is a blown head gasket. This is the part that creates the seal between the top of the engine (containing valve train, intake, exhaust, spark plugs, etc.) and the bottom of the engine (containing the pistons, crankshaft, oil pump, etc.).
This gasket will blow to relieve the excess pressure caused by an overheating engine (which can actually make your coolant boil producing steam). Repair will be expensive but is do-able and fairly routine.
Other possiblities are a cracked block, broken rings, badly scored cylinders, burned or broken valves, etc. All of these are more expensive and some (like a cracked block) are even questionable doing depending on the value of your car.
One simple thing to check first. If the installer of the fan bumped, damaged or somehow changed the wiring to the injectors, or the spark plugs, or another sensor, this could cause your symptoms (and would be way cheaper to repair) so check it out first before assuming the worst.
A quick check for a blown head gasket: After the car has been driven enough to get fully warmed and the engine has been off for half an hour or so, pull your dipstick and see if there is foamy or bubbly oil on the bottom of it. Water (from coolant) will almost always mix with the oil if the gasket is blown. You could also look for shiny, multicolored liquid material floating on the top of your coolant (oil) but this is less likely to happen.
A mechanic can check the electrical side of things quickly and cheaply by putting your vehicle on a diagnostic testing machine.
Your engine's computer "talks" to the computer in the machine and together they arrive at the cause of the problem. This is much more comprehensive than a simple "code reader" that is placed on the engine connector.
At any rate, get it checked out. If the gasket is blown, you will do further damage by driving the car. If it is just a bad wire, you are wasting fuel and could do damage anyway.
Any help?

if your car has aluminum heads, and you over heated it, you very likely(if not definately) warped the head, this would allow coolant to be sucked into the cylanders, and they don't like water in there when they're trying to burn. There are a number of test you could do, check you oil, is the bottom of the dipstick white, if so you have water and that's not good, second, pull the spark plugs , any fluid in there??

Since you don't say the brand of your car or the engine, I can only guess. If it has an aluminum head, it could have cracked the head, warped the head, or just blown the head gasket.

it would appear to me that your fan was either not installed right or was damaged and is vibrating. even the smallest bend can make it wobble and shake. also are you sure the car over heated because of the fan? if you were on the highway that should not matter because the wind speed would cool the radiator.

Head gasket,or cracked block,or warped head. Hope the main bearings are not blue.Aluminum heads will not take much overheating.

overheating is not good for an engine. you probably blew the finneghan pin or the stratus rod.
