Well, i took the thermostat out and checked the Spring, not ceased and still very light to push. Then the thermostat was put in with the spring facing the back of the engine. Now, I also took out the themostat and it was still doig the same...now, I went to go work on it, and now the car is running on 3cyls. I dont know what's going on, but it was running like new when I got it., except for the overheating. I also would like to know where the waterpump is located. is it in the timing belt cover, run by the belt???
