Water Pump Pulley Removal on 2010 (how to remove bolts?)

[pbody]

How do I remove the water pump pulley bolts? I removed the belts, headlight, and raised the engine after removing the mount bolts.

Do I need to put the belts back on to remove the bolts? Or is there a trick to keep the pulley from moving when I turn the bolts? The screwdriver trick does not work on this car.

you REALLY need the GM special Tool to do this job properly, it saves a TON of Time and Headache (and prevents damage to expensive bits!); there just isn't enough room for a ratchet (even a 1/4" is too large for the gap between the Water Pump pulley bolts and the frame rail), and a Torx socket. Also, the bolts that secure the water pump to the block are external torx and are difficult with a set of standard external torx sockets, and the special tool has the proper size and length for the pump bolts. the tool number is EN-49201, and you can find them all day on Ebay for WELL BELOW what GM asks for it!

5mm Allen socket for the 3 bolts , must be the socket the normal ones you can't really use

You don't need a special tool. Remove the wheel, and loosen the serpentine belt. Remove the air box. Remove the nut that holds down the AC line. Pull up the line hold down and put the nut back on the stud (for safe keeping.) You can turn the water pump pulley by turning the power steering pump pulley. You can hold the water pump pulley in place by holding the ps pulley. The torx socket can fit on the water pump pulley bolts one at a time in the same position. This is also the best method to remove and replace the ps stretch belt.

Another way to hold the water pump pulley in place to torque the bolts is to tension the serpentine belt. Tighten one WP pulley bolt. Then loosen the serpentine belt to rotate the WP pulley. Tighten the second bolt. Loosen the serpentine belt again to rotate the pulley, and then tighten the last bolt. Simple.

Mine have 3 torx bolts you need a 1/4 short torx socket and and a rachet they are 8mm thread so a long rachet helps leaving the belt on and turning the crank to get to the bolts pulling out the right headlight opens up things
