Water pump is located on the side with all the belts. Find the water pump pully and LOOSEN the bolts that keep the pully on the shaft of the water pump. Once they are LOOSEN remove the belt. Then you can remove the pully bolts the rest of the way. Pully MIGHT be stuck on there, a couple of taps should loosen it enough to where you can pop it off by hand. Now if I recall this vechile correctly, there MIGHT be another pully that will hinder you. It's just easier to take it off right away. It's right above the water pump. I BELIVE it's an idler pully. Dosn't do anything but to help keep the belt on it's correct path. There should be one bolt in the middle of this pully, undo the bolt and pully will pop off. Make sure you REMEMBER how it was on. So that you put it back on the right way. Then, there are 2 or 3 different sized bolts that keep the water pump on. Remove the bolts, one at a time, and make sure you REMEMBER where they went. If you remember now, it will save time guessing later. Ok, once you are sure that ALL the bolts are removed, you can try to pop off the pump. If it dosn't come by hand, use a screw driver to pry a corner up and then do the rest by hand. Once it's off, it's time to clean the motor side of the pump. See, on these cars it's not a complete pump like it use to be, it's a half pump. Meaning, when you look at one side you can see the fins that move the water. Anyways, when you are at the parts store, pick up some emery cloth. It's sort of like sand paper. Well, once the pump is off, use a razor blade and scrape off the silcone that's on the block. Then use the emery cloth to make is nice and clean getting all of it off. Once that's complete, put the new gasket on the pump and reinstall. Put all the bolts in BEFORE tighting them down. And when you do tighten them, do it by hand! Using an air tool will break the bolt or strip the threads in the alunimium block and then it has to go to a mechanic. Once all the bolts are tight fill up the reservor to check for leaks. Also go back over the bolts one more time and make sure all are tight. Doing this now, will save you headace later. Then put the rest of the things back on in the order you took them off. That's it exepct for bleeding the cooling system. I assume you know how to do this, if not, let me know.

  • I changed the water pump on the 4.5, 1990 DeVilll , twice, both times to make things easer, I loosen all motor mounts on the tranny end and removed the nuts on the mount at the pump end, and jacked the engine up about 6 inches, be sure to put a 2x4 across the oil pan and tranny, this puts the pump where you can get to the bolts., there is a gasket behind the plate the pump mounts on, when everthing is installed,,,sloooowly lower the engine down with a large enought screw driver line up the mount bolts... I'm planning to do this again on a 89 devill, have a Blessed day...pep

How do I replace the water pump on my Cadillac Deville?


Hi.

Here the instructions.

  • Take off the plastic cover located near the top of the radiator if present.
  • Remove the protective shield located on top of the belt pulling the water pump. You will need to undo two 10mm nuts and one 10mm bolt.
  • Undo the 10mm nut that holds water pump housing togeter with the oil dipstick.
  • Take off the air intake assembly.
  • Move the PCM computer to one side, ensure that the module is safely placed.
  • Release the belt tensioner using a big flat screwdriver.
  • Remove the serpentine belt from the water pump pulley
  • Remove the upper radiator hose. This is held by a metal clamp. Use plyers to remove the clamp.
  • Remove also the clamp from the thermostat housing bypass hose, without removing the hose (you have to bleed coolant first).
  • Unscrew the four 10mm bolts that hold the water pump housing and letcoolant drain from water pump plug. At this point you can also removethe lower radiator hose to drain faster.
  • After coolant drains remove the water pump housing.
  • At this point you have to use a special Water Pump removal tool onwater pump cand turn clockwise until the pump is sliding off thehousing.
  • Remove the pump and the o-ring located inside the water pump housing.
  • Clean and grease the area, put a new o-ring and install back water pump housing
  • Install the new water pump using the special tool and following operations in reverse order.

You may need to use sealant tabs from a Cadillac or GM dealer. Here is what you need.
Better going to your local dealer to get the best product for yourCadillac. You will also need a 3/8'' ratchet, socket and extensions

Youmay also need to replace the housing cover gasket. You will need toreplace the O-Ring, that usually comes with the new pump.
When installing new pump you must also ensure that the new pump is aligned correctly,one of the tabs on the pump housing is different and will lock up the pump, so it must bealigned properly while installing.

Coolant leaking under vehicle


The heater hose that run behind and below the engine has a plastic Y split where the hoses run to the thermostat and in to the firewall to the heater core. The plastic piece can crack and cause leaks as well as overheating. Easiest way to see it is standing on the driver side of the car and looking down behind the engine with a flashlight while it is running.

Check engin light comes on and vehical shutters when trying to excellerate. checked water and it was out, put fresh atifreeze 50/50 mix and it is still doing same thing. this vehical has a new water pump...


If you replace the water pump and thermostat and nothing is leaking, and still the coolant is low, then you vehicle is burning coolant, that give you a misfire and a flashing check engine light. so look like you need a head gasket job.

Sorry if I don't put things in a nice way.
If the thermostat is bad either the temperature is low, or is hot but no misfire (chatters)

How do you replace a fuel pump for a 2000 hyundai sonata, 2.4 engine? Where is the fuel pump located?


You will have to obtain a siphon kit from your local auto parts store and siphon the gas out of your gas tank, you will need to drop your gas tank out of your vehical, the electronic fuel pump is located inside the gas tank, the reason for removing the gas out of the tank is because of you try and remove the tank with it halfway full or full the tank will be to heavy and you run the risk of dropping it and ripping off the delivery and return lines as well as the electrical connections for the pump from the vehical, so make sure you have a way of draining the gas it will make your job much easier as far as removal of the tank is concerned......
