Im changing my water pump and it has a pully that the belt gos on in front of it and the pully has 1 big bolt in the middle of it and like 4 small ones around it and when i try to undo the bolts the pully turns and im not quite the mechanic but i do know that the pully has to come off 1st so how do i take out the bolts without the pully turning???? and yes the belt is off and battery id disconnected and the car is not hot it hasnt ran in days. and it has a 3.4 v6
For the best answers, search on this site https://shorturl.im/awNHT Did you hit up both bleeders? Run the car until the thermostat opens. You'll know when because the cooling fan will cycle on. With the car running, and the Rad cap off, start with the bleeder near the thermostat housing (RH side as you're looking at the motor from the front.) Leave it open until you have steady stream of coolant flowing. Close, and move to the bleeder on the left. It's on the metal tubing above the water pump. Same thing, open until coolant flows. Close bleeder, then run the engine up manually at the throttle body. Keep adding coolant to the radiator untill it's topped off with no bubbles coming out. Cap the radiator before letting off the gas. Fill the resevoir, to the full hot line or a little over. Any random small bubble with make their way to the res, being replaced by fluid.
Leaving the belt on with tension to hold the pulley while you break loose the 4 bolts is the easiest way... you will have to come up with a way to hold it still while loosening the bolts... one way is to take a good sized flat tip screwdriver and while you are holding it wedged between the shaft and one of the bolts while breaking the other bolts loose..
actually it works better if you leave the belt tight on the pulley, the tension holds the pulley so you can loosen the bolts, and even that big one, I think, you will need a decent pulley puller to get that pulley off, I suggest you buy a new water pump if you can afford it, otherwise you will but putting water pumps on every year or so, as rebuilt are not long lasting, best of luck, be careful around that radiator with the fan.
