well today I was TRYING to change out my thermostat, but guess what?? Can't get the belt tensioner bolt to budge. So a friend came over and told me that my thermostat is fine its my water pump thats not working. He said that since my thermostat tube is cold and my other tube coming out of the motor entering the radiater is hot water is getting circulating. Well now I'm really pissed. So is he correct? is my water pump really gone. then how much will it cost to get fixed??? O yeah when my car gets hot my fans don't work either. Any help will greatly be appreciated.
