I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

If I understand your problem correctly if sounds as if the engine mount bolts broke which allowed the engine to drop which may have kinked your radiator hose, that caused a flow problem and the engine over heated.
If this is what you are saying it is possible the inner liner of the hose ruptured and folded in causeing a restriction in the hose, this use to be fairly common with hose's in the 50's and 60's but is pretty rare these days.
You need to check the hose for soft spots, if you do not find anything there its time for some tests, the first would be to remove the thermostat and run the engine to see if you have flow in the radiator, if your radiator has a cap at the side tank run the engine with the coolant a little low, if there is flow your will be able to see the coolant coming out of the tubes inside at the top of the core. If there is no flow you need to take a better look at the hose and possible the water pump impeller.

yes. the impellor on these engines have a tendency to come off the water pump.First you can see if the pump is working by removing a heater hose then have someone to start the engine. if the water sprays a good, solid stream out then the water pump is good. if the water just barely comes out or not at all then the pump is weak or "bad".

Did the engine overheat before the water pump was replaced? If so, you may have a warped cylinder head and/or blown head gasket.
Was the radiator full of rusty-colored liquid before you flushed it? If so, your radiator is probably restricted with rust deposits in the cooling tubes. Flushing WILL NOT get this stuff out. The radiator MUST be replaced if this is the case. Your heater core is probably not in real good shape either, so you should be expecting some heating problems this winter.
If the above is not the correct answer, then you should check to make sure the temperature gauge is not "LYING" to you. This could be caused by a defective gauge, a bad temperature sending unit, or faulty wiring.
The way to check this is with a scan tool that can read engine data and an infrared thermometer. While reading the coolant temperature data from the computer, check the cylinder head temperature with the infrared thermomometer. The readings you get should be within 5 degrees (F) of each other. If the computer data does not match the thermometer within the 5 degrees, then the sending unit for the computer should be replaced.
Then look at the gauge to see if the gauge reading is appropriate to the temperature readings that you took. Normal operating temperature is between 190 and 230 degrees. This should place the gauge at slightly to the right of center to about 5/8ths of the way to HOT. If the readings you took are OK and the gauge is reading higher than this, then you should try replacing the temperature sending unit for the gauge and see if that fixes the problem.
Please note that there are TWO temp sending units: One for the gauge and one for the computer.
