You will need to Locate the Belt Tensioner. It has a Large Pulley on a Bracket that Has a Bolt in the Middle and a Smaller Pulley that Goes Under the Belt and Holds Tension on it. You will need to get a Wratchet, Socket, and Cheater Bar. Turn the Bolt On the Top Large Pulley with the Wratchet and Cheater Bar. This will Lower the Smaller Pulley So that you will be Able to Remove the Belt. Please Rate My Response! Thanks!

Need to replace waterpump


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.

Water pump replacement 99 malibue


  • When replacing a water pump, it is necessary to drain the cooling system.
  • Any components--belts, fan, fan shroud, shaft spacers, or viscous drive clutch--should be removed to make the pump accessible. Some pumps are attached to the cylinder block as shown below.
f11-60.jpg Installing a water pump.
  • Loosen and remove the bolts in a crisscross pattern from the center outward.
  • Insert a rag into the block opening and scrape off any remains of the old gasket.
WARNING When working on the coolant system (for example, replacing the water pump or thermostat), a certain amount of coolant will spill on the floor. The antifreeze in the coolant causes it to be very slippery. Always immediately wipe up any coolant that spills to reduce or eliminate the chance of injury.
  • When replacing a water pump, always follow the procedures recommended by the manufacturer.
  • Most often a coating of good waterproof sealer should be applied to a new gasket before it is placed into position on the water pump.
  • Coat the other side of the gasket with sealer, and position the pump against the engine block until it is properly seated.
  • Install the mounting bolts and tighten them evenly in a staggered sequence to the torque specifications with a torque wrench. Careless tightening could cause the pump housing to crack. Check the pump to make sure it rotates freely.
  • The water pumps on many late-model OHC engines are driven by the engine's timing belt. When replacing the water pump on these engines, always replace the timing belt.
  • Make sure all pulleys and gears are aligned according to specifications when installing the belt.

Looking at belt routing below, the water pump is the pulley all the way to the right, will have 4 10mm bolt's holding the water pump pulley, loosen 4 small bolt's on water pump pulley, remove serpentine belt, remove small water pump pulley bolt's all the way off, remove pulley, now you can see water pump, remove small 8mm bolt's from water pump, now water pump will come right off, hope this was very helpful.

Recently bought a 2003 Chevy Malibu. Great car. A couple of days ago it started making a "chirping" sound when in the car and more of a light click when you're outside. It's under the hood but couldn't...


well the chirp sounds like a belt problem but the light click is usualy the lifters try using a higher grade of gas,and hope its not a berring going in the water pump.

Car ran hot twice and is making a squeaking sound


Not much info to go on, but: Most squeaking is from 3 sources. 1.) Water Pump Bearing. Get some water pump lubricant in there quick to avoid ruining that bearing. (about $3.00) 2.) Idler Belt Tensioner You may be able to lube the back side of this with WD-40, but too much is bad for the serpentine belt. 3.) Power Steering Pump, does not sound like you problem.
