i have a mid 90's 853c bobcat. i think the waterpump is bad.....i put a new thermostat, flushed radiator, and after all this i open cap when i started it and had my son rev the engin up and down to see if the coolent was moving in the radiator.....nothing seemed any different when he revved it. fluid stayed at same level, and did not seem to move. i dont have any leaks near the pump that i see, but after all i did i am stumped. does this sound like the water pump? if so where can i order the parts online? local shop is terrible, and i would rather not deal with them. thanks alot.
