I'm trying to remove the crankshaft pully off of a 2000 Oldsmobile intrigue. I was able to remove the center bolt bolt the the pully doesn't have any holes to use a puller with how can I take it off.

13mm socket with a 12" extender to remove the bolts.

It is very easy! Take off belt by putting a wrench or socket on tensioner pully and rotating it. belt will come right off. You will have to drain coolant. then take out all of the bolts holding the water pump on. you will have to remove the power sterring pump to get to the very back bolt. Make sure you clean old gasket off of the motor and install new gasket with sealer. reassemble in reverse order.
On '98s at least there is an access hole in the p/s pulley that gives you access to that last bolt
I found no access hole except through the power steering which was easier to remove than the PS pully that a pully remover does not have sufficient room. Two bolts top and bottom through the access holes for the PS pump and it is out of the way of the last water pump bolt.

The crankshaft pulley will have one big bolt in the center and it takes a lot of torque to loosen it. Once the bolt is out ( after all the belts are removed) you may need a tool called a harmonic balancer puller. It will have slots in it that you put bolts through and bolt it to the pulley, then there is one large bolt in the center that presses against the crankshaft and forces the pulley off.

its on the top of the motor in the front by the cam shafts.

Hello: Something doesn't sound correct. Is the water pump driven by the belt that drives the alternator, a/c compressor and power steering pump? If so the you may have to tap on it with a hammer to break it loose from the engine. Make sure you clean all the old gasket off before installing the replacement.

. Its above the starter going into the side of the block. (front side of the engine) Disconnect the battery. Remove the starter. Remove the wIre CONNECTOR plug to the sensor. The sensor has 1 bolt holding it in. Remove the bolt, you may have to wiggle the sensor at the base a bit as you pull it out. Replace, and make sure it is pushed in all of the way. Replace the bolt, wire plug, starter, reconnect the battery.

This is a quick answer. Its above the starter going into the side of the block. (front side of the engine) Disconnect the battery. Remove the starter. Remove the wore plug into the sensor.

Should be located around 11:00 on front of engine at crank pully.

Normally...three bolts for the pulley assembly, and one large center bolt, and yes...a steering wheel puller will work, but make sure the puller doesn't sit into the center hole threads, or they will be destroyed. Sometimes a nut in here will prevent that.

Im not sure what engine you have since this information was not provided. But the Power Steering Pump pulley usually has some 'holes' on the pulley in which you can get a wrench through to loosen and remove the bolt.
