Olny if it is making a grinding noise or leaking right behind the pullie

 

If I read things correctly, you took the top radiator hose off with the radiator full, engine running and engine up to normal temp. If you had no flow coming from the engine then the thermostat was stuck closed. Make sure my assumptions are correct, because if the engine is cold, no water will be flowing through the upper radiator hose.

 

There will be coolant in the upper hose if the car is up to temp. because of the pressure throughout the system... If you dont have pressure then that is another problem...

 

If the car is up to temp, water shoud be flowing through the thermostat, upper radiator hose, into the radiator.

 

i will try this agian but this time i will just squezz the hose instead of taking it off

 

Good idea.
Or I have another way that I think is the best. Use a thermometer in the radiator.
With the engine cold, remove the radiator cap, put a thermometer in the water, start the engine, when the temp gauge gets to normal, the thermostat should open allowing hot water to flow to the radiator, you should then see the water in the radiator heatup as shown on the thermometer. If the engine temp goes above normal and the thermometer in the radiator does not show hot water then the thermostat is stuck closed.

 

yeah i got it up to operating temps and the hose was Colddddd, so i called a buddy over to see what he thinks, and he think the radiators fine its just the thermo

 

The only thing i though was that if it was the thermostat wouldn't it heat up real fast, because it takes a long time for it to heat up

 

where were you looking?

The heat up will be the same up to normal temp. Keep in mind the thermostat is closed, blocking flow until operating temp is reached, then it opens to maintain temp. It works like a temperature control valve to maintain engine temp. If it is a 180 degree, it will not open until the water in the engine gets to 180.
