Usually you don't - many are not made to be rebuildable. You typically buy a new one and put it in.

How to repair a front pump seal on a '99 cadillac deville concourse

You did not specify which pump. If it's the water pump, you will probably need to replace it, as it is probably the shaft, not a pump housing seal, that is leaking. If it is the housing seal, you will still need to pull the pump to replace it - there is a special tool for this.

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


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.

98 caddy deville nothstar v8 how to replace heater coil have no heat and I'm loosing water somewhere

the heater core in a 1998 Cadillac is very tricky to replace.
start with getting a pressure test to determine where the exact location of the leak is, it may not be the heater core.
if you do decide to pull the dash apart to change the core make sure the battery is disconnected for at least an hour to allow the airbag system to discharge.

Need the location of the PCV on a 62 Cadillac 390 ci. Thanks

PCV valve should be in the valve cover with a hose coming out of it. Pull it straight out, take it off of the hose, and shake it to see if the valve is loose, as it should be.

Water pump still leaks 92 cadillac deville

yes always use gasket sealer on both sides of the gasket. and make sure the old gasket is completely removed but do not use a chisel ar anything as you will leave gouges in the metal and cause a leak. Best to clean it is with some sand paper and just take your time. And just a thougtht but all i use is the black gasket sealer. It seems to wwork the best.

Well,if getting adequate fuel supply to the carb,then the problem is probably inside the carb now.Make certain a good flow of fuel to the carb,and if so,pull the carb off and recheck the floats drop and level height,also the needles and seats inside,and the gaskets for good condition.
