Howdy Monte fansThere's not a lot of working room, so make sure you bring all your patience into the shop!First step, disconnect the negative battery cable, take the rad cap off, the reservoir cap off and, if you have one, open the bleeder screw on the thermostat housing 2 or 3 turns.Take out the rad drain plug (located in the lower left corner of the rad) and drain the rad.Next step, remove the plastic coolant recovery tank (screw at the top,nut at the back and plastic pin at the bottom)there's a small belt guard just above the water pump that needs to come off next.There are 4 bolts that hold the water punp pulley on and the next step is to loosen them by wedging a screwdriver between two bolts and working your way around with a wrench. Now you have to take the bolt out of the center of the serpentine belt tensioner and take the tensioner off. Move the belt out of the way and finish taking the bolts out of the water pump pulley.There are 5 bolts that hold the pump on, back them out and the pump will come off with a tap froma soft hammer.IMPORTANT! - 3.4 pumps have a locating mark at the top to align them properly. Make sure the replacement pump has one and that the pump is identical to the one you took off.Clean up the bolt threads, gasket surface and bolt holes, give the engine surface a wipe with acetone and reassemble in the reverse order.Remember to tighten the pump bolts in a circular pattern, a 1/4 turn at a time so the pump doesn't warp.Always use the recommended torque specs, aluminum just loves to bend and warp if ya don't.

Drain the water from your 1997 Chevy Monte Carlo cooling system. Remove the water supply hose. Remove the thermostat housing retaining bolts. The thermostat will lift out. Reverse the process to install the new thermostat.
