The first thing I would check is the head gaskets. Most likely this is the problem. Hopefully it is not a problem with the block. It could also have a problem in the intake area. If the engine overheats, and since we already know there is a loss of coolant, be sure the fan works, rad is good, thermostate is good and replaced, and stop driving the car. More damage will occur. The job to change the head gaskets is very expensive. Hours of labor are around 20 or less. Plus the cost of having the heads checked and serviced. This must be done. Just the heads alone are around $ 600.00 to service. Has the intake manifold been replaced yet, if not, there is a recall by Ford. The cross over where the coolant thermostate is is made of plastic. the new ones are not. The plastic will crack and develop a leak, mostly to the outside of the engine, but it is possible to leak in the inside, check that also. First, a pressure test of the system might help find where the leak is. good luck, if u need more info, ask me on my message board. Good luck.
The engine is overheating.
could be your thermostat or you have no antifreeze coolant or your water pump is going bad
If it is a vortec engine, it is probably the lower intake manifold gasket. In most cases you can smell it when the engine is hot.
if fans are working and thermostat is good welcome to the world of northstar famous headgasket/faulty headbolt and stripped block crap engine problem
The engine could possibly seize.
the freeze plugs on the side of the motor could be done.
One common cause is when you need antifreeze fluid for your radiator. Often times, the liquid becomes completely used and that is when your engine heats up, which could further result in a cracked radiator.
It could possibly be the thermostat or the cooling fan. Let the engine warm up and when it gets to 232 to 235 degrees the cooling fan should come on. If not you need to go from there.
Overheating the engine shouldn't effect the transmission. Overheating the transmission could.
Look just below the water pump to see if any antifreeze is visible. Water pumps will sometimes leak and drip out antifreeze. Check the engine oil to see if antifreeze is mixed with the oil, indicating a blown head gasket.
Valves will clatter if the engine is overheating.Valves will clatter if the engine is overheating.
Could be a problem with the engine cooling fan , water pump , restricted radiator , any body else have any ideas ?
