Update** Problem solved: After changing the head gasket, it ran ... Overheating problems with Chevy Malibu '01 .... Malibu 3100Intake Manifold Gasket Inexpensive Miracle Repair - Duration: 12:21. by Upub5 42,848 views.
Well, a faulty water pump could cause the engine to overheat fairly quickly, but additional pressure in the cooling system is usually caused by a leaking head gasket.
1. Remove mounting bolts and remove upper timing cover and gasket. Drain coolant into clean bucket. 2. Loosen the 4 water pump pulley mounting bolts. Loosen alternator adjusting and mounting bolts and remove the belt. 3. Remove the water pump pulley bolts and the pulley. 4. Remove the water pump inlet mounting bolt from the side of the block and then remove the 2 nuts attaching the pipe to the water pump. Remove the pipe. 5. Remove the mounting bracket bolt and then remove the dipstick tube. Plug the hole with a rag. Remove the right hand under cover and the power steering adjusting bracket ( if it has power steering). 6.Remove the 3 bolts and remove the water pump. Keep coolant OFF the timing belt (plenty of rags to soak it up)., Remove the O ring from the block. 7. To install a new pump, start by replacing the O ring in the block. Then the reverse of these steps. 8. Water pump mounting bolts are torqued to 11 ft.lbs only. Also replace the O ring on the dipstick tube and coat it with oil before reinstalling. 9. Refill the cooling system and run the engine up to operating temperature, with the heater running. This will force the air out of the system. Once the air is out top up the rad and replace the rad cap.
Your Malibu is equipped with probably the EASIEST water pump in the word to change.
Drain the cooling system. Loosen the water pump pulley bolts. Remove the drive belt. Remove the water pump pulley bolts and pulley. Remove the water pump bolts, pump and gasket. Clean the water pump mating surfaces. Install the water pump and reassemble in reverse order
Hint: The O-ring that seals the water pump is much easier to install if you use a little dielectric grease to "stick" it to the water pump before installing. This O-ring needs to expand and contract and move freely in the water pump groove due to extreme changes in engine temperature. The dielectric grease will actually help accomplish this. DO NOT use RTV silicone to "glue" the O-ring.
WELL YOU NEED TO DRAIN COOLANT SYSTEM.PLACE A LARGE DRAIN PAN UNDER THE RADIATOR TO CATCH COOLANT WHILE DRAINING RADIATOR.ONCE ALL COOLANT DRAINED OUT.REMOVE DRIVE BELT.REMOVE WATER PUMP PULLEY.REMOVE POWER STEERING PUMP AND MOVE IT ASIDE.THEN REMOVE WATER PUMP.MAKE WATER PUMP MOUNTING SURFACE CLEAN THEN INSTALL NEW WATER PUMP AND GASKET IN PLACE.IF WATER PUMP GASKET IS PAPER TYPE PUT GASKET SEALANT ON BOTH SIDES OF THE GASKET.IF YOU HAVE RUBBER GASKET DONT USE NO GASKET SEALANT.INSTALL NEW WATER PUMP TORQUE LONG BOLTS TO 25 FT LBS AND TORQUE SHORT BOLTS TO 16 FT LBS.TORQUE WATER PUMP PULLEY TO 115 INCH POUNDS.TORQUE POWER STEERING PUMP BOLTS TO 25 FT LBS.THEN INSTALL DRIVE BELT.FILL THE COOLANT SYSTEM.START THE VECHICLE AND CHECK FOR LEAKS.
(step 1 ) the torque specs for the heads are---1998 through 2001 are 37 foot lbs. ( step 2) rotate an additional 90-degrees (1/4 turn). intake manifold bolts ( lower ) step 1-- 62 in-lbs, step 2--115 in-lbs. intake manifold bolts/studs ( upper ) 18 ft-lbs. this is for the 3.1 v-6, have a good day!

if it got the 3.4 in it it a walk in the park. take the belt off 4 pully bolts then 5 water pump bolts clean off old gasket then reinstell. look at water pump real good it only goes on 1 way. good luck. o brake the pully bolt loose before you take the belt off.and youll need a small pan to drain anti freeze it
it is located behind the power steering pump. You need to remove the
power steering pump to get to it which requires removing the engine
mount next to it to get the bottom bolt out of the power steering pump.
The sensor is directly behind the power steering pump. You can follow
the cable that goes behind the pump. It is the only one there.
