How to change a water pump


First drain the coolant if possible (you will find a drain **** on the bottom drivers side of rad). Loosen the water pump pulley bolts while serpentine belt still attached (10mm X 4). Remove the serpentine belt, and plastic diagram bracket just above the waterpump. Remove the (8mm bolts X 5) holding the water pump to front engine housing. Note the little arrow or triangle at the top of waterpump when removing, it will help you to install new water pump in same location. Scrape off most of the old gasket material, use fine sand paper to clean engine surface as best as possible. Install new gasket to water pump, and align the holes (it only goes on one way, and maybe upside down if they don't line up). Locate arrow and reinstall, torque 5 bolts to 89 in/lbs tight but not too tight. Reinstall pulley, serpentine belt and bracket. Tighten the pulley bolts, refill coolant (close drain ****). Just above the waterpump there is a coolant hose with a little 7mm screw for a bleeder. Open the bleeder (engine off). Continue to fill rad with coolant until it comes out bleeder. Close bleeder and test run. Recheck the coolant level later when cooled.

Where can I find a diagram for the cooling system on a 1998 cadillac deville online? We need to know the position of the thermostat, and water pump.


Hello: I don't know of any free information unless you join a website called AllData but I can explain where the thermostat and Waterpump are located on a Cadillac Northstar engine.
Thermostat: Follow the lower radiator hose from the radiator to where it hooks to the engine. The nipple where the hose connects has 2 10mm bolt heads, remove the bolts, the thermostat is behind it, note the position it comes out so you can install the new one the same way. Waterpump is in the same area, remove the 4 10mm bolts that hold the cover of the Waterpump housing. You may have to remove a heater hose. You will have to have a special tool (can get one at Advance Auto Parts) to remove and install the new Waterpump. Both of these items are on the drivers side on the engine.

Procedure on changing waterpump


  1. first drain the cooling system.
  2. loosen bolts on the waterpump pulley and remove the inner fender cover on the pass/side.
  3. remove the surpentine fan belt, note; make a diagram of the belt routing so belt will go back on the right way.
  4. remove the bolts you loosened on the pump pulley, use a pry bar to pry engine back to have enough room to remove the waterpump pulley.
  5. remove the bolts holding waterpump, you will want a pan under the van to catch coolant when waterpump is removed,
  6. remove the pump and clean old gasket off the block and install new pump,
  7. reverse to install new pump and fill system with coolant allow engine to run until thremostat opens,hope this is helpful. heres a few diagrams of the waterpump and the cover and the belt routing, good luck and hope this is helpful.

Need to view a diagram of 2002 cadillac deville engine to know what small belt came off of on drivers side next to engine


Hello, That belt drives the waterpump, if the belt came off then you have a problem. Either the pulley on the tensioner is locked up or the waterpump is locked up. It may have destroyed the pulley on the camshaft that drives the waterpump. Remove the black metal guard that covers the large pulley. Hope this helps to get you started.
