1997 cadillac deville water pump

Michelle,

The 1997 V8 engine in the car is fitted with coil packs which are quite visible on the top of the engine. These need to be replaced when they eventually fail as is common.
Here is a video on the coils which may help you.................

Hope helps.

Try to flush and fill with new fluid to get the passageways free of sediment.

Or, try to see if the fans are coming on at the right speed at operating temperature. May require new fans/relays/wiring to fix this problem.

I have a 1997 Cadillac Deville that was overheating its Northstar engine and it required service amounting to about $700.00 or so from an auto electric shop, but afterwards it ran cooler.

Good luck on this repair.

easy fix, go to local parts store, a special socket is needed to do the job!

check all hoses going to water pump and make sure they are not leaking, if hoses are not leaking then pump is going out. need to replace asap, if car has northstar engine DO NOT GET IT HOT average cost to replace head gasket on northstar is $2300.00 plus

you don't, the water pump has pulley built in. (it's located on the driver's side in the rear of the engine in case you mis-understand that it's on the front of the engine )
there's a special tool to remove and install the water pump.
if you have the tool the the job is very easy

the belt is on back of head,no hard to do.remove cover,release tension, by pulling back on tensioner.
with car off grab belt with your hand and pull,this way you can see how tensioer releases tension.

NOt enough info. Where is the water coming from top or bottom? Could be a leak at a seam, could be a loose cap, could be a leaky overflow bottle, could be a loose hose connection and it could be a crack or leaking hose.

Northstar? If so get one at your local auto parts store!
