How do you replace the water pump on a 1991 Cadillac Deville 4.9L front wheel drive?
It is a big job so get a manual from the parts store.
i just did mine the other day, What you want to do go get your water pump and your gasket and blue gasket sealer a big tube not them little packets,remove batter and raidiator overflow, leave the belt on and loosen the 3 bolts on the pulley(which is a pain in the ass, use a screwdriver or another wrench 10mm i think, then remove the belt and remove all the other bolts holding the pump to the engine face, there are alot of them just to warn you, after you remove the pump scrape off where the old gasket was with a putty knife, apply gasket sealer to the gasket and then place on the gasket then the same with the pump, you then have to put the bolts back in and then you have to tighten up the pulley by hand then put belt on then tighten bolts more, although it did look like there was lock tight or something on the pulley bolts i removed i didnt put nothing on i just tightened them as much as i could i have not checked there tightness yet though, if you do this then you may want to check them a day or two after
This is all correct, but some tips: after scraping the block clean, spray with brake cleaner and wipe clean with a rag. Also, dont use that silicone goop. Instead use high tack. Its much cleaner and goes on much neater. I have a more detailed description as an answer to a 92 caddy water pump replacement that will work for all 4.9L Here it is:
- Remove the coolant overflow bottle.
- Remove the battery.
- Loosen the pulley bolts.
- Loosen or remove the drive belt.
- Remove pulley bolts
- Remove all studs and bolts from old water pump.
- Pull old pump off. Use a screwdriver to start it but be careful not to bend the old pump. Also, tapping the center of the pulley lightly with a hammer may help loosen it. If it is hard to get out, check and make sure all bolts are removed. When you remove the pump, there will not be enough room to remove the pulley drum from the pump. This is important to remember when installing the new water pump.
- Scrape area off with a gasket scraper and razor blade to remove old gasket. Make sure its clean! Spray it with brake cleaner and wipe clean afterward.
- Spray both sides of the new gasket with high tack. High tack works much better than the goop because it is clean, even, and seals well.
- Slip gasket in carefully and be sure it fits properly over bolts and is in correct placement against block. Press down to ensure seal.
- Spray the inside of the water pump with high tack evenly.
- Install water pump into correct place against block making sure that pulley drum is already hanging from new pump or you will not get it on afterward!
- Install bolts and studs and tighten down.
- Install pulley screws and tighten as best you can.
- Reinstall and tighten drive belt.
- Finish tightening pulley bolts.
- Reinstall battery and coolant overflow bottle being sure that bottle is empty.
- Let sealant dry overnight.
- Fill system with water next day/morning and run/drive car as normal until you are sure it is not leaking.
- If no leaks exist, drain system and fill with proper coolant mixture.
- Return old water pump in box for return on core fee.
Ive done this twice on a 92 Sedan DeVille, so just post any questions you have. If your wondering why I did it twice, the part store sold me a bad pump that went out within two months.

Replace the shocks, or struts if equipped.
What is the unit of measures for resistors?
Resistor values are given in ohms. A value may be selected to deliver a specific current at a given voltage. This is given in what is known as Ohm's Law where:
Voltage (V) = Current (A) X Resistance (Ohm)
A 12ohm resistor placed across a 12V battery would pass 1Amp of current and put out 12W of heat.
How can you tell when the engine is bad on a 1994 sedan deville cadillac?
The most serious problem that a 15 year old Northstar would suffer from is a bad headgasket. There is a relatively easy procedure to test for the presence of exhaust gases in the coolant. Most larger auto parts stores have the kit to do this. It is the only FOOLPROOF way to test for a bad HG, other than a cylinder pressure test. Northstars, despite their (unearned) bad reputation in some circles, are quite well designed.

Water pump for 96 Cadillac deville?
The water pump is on the front of the engine. If the pump goes bad, the engine can over heat causing severe damage.
1. Turn ignition switch to the ON position. Do NOT start the engine.
2. Simultaneously push and hold the OFF and WARMER buttons on your Electronic Climate Control panel for 3 seconds and then release them and while watching, you'll see your fuel data display change.
3. On your fuel data display, you will see LETTERS & NUMBERS displayed. Be prepared to write them down. As they run through fairly quickly, I suggest making a column list ahead of time on a piece of paper. Heading each of the four columns in order with these codes, EE And E And FF And F . Then as these codes flash, write down the number displayed under each of these coresponding codes number
Then when it stop's at .7.0 the code's are done.4. Turn ignition switch OFF.Now once you have the error codes, the answer to your question maybe at your finger tips.Good LuckAsk Jack
NewCheck that none of the wires are touching the exhaust manifold, you can use tie straps to tie the cables so that they are not touching or near an extremely hot surface. You can burn up a wire and cause SERIOUS engine damage, if its been goin on for 2 weeks or so get your front motor mounts checked out, theres a possibility it may have cracked.Did you change the rotor button as well? This problem your describing really needs to be described in much more detail as to how and when this miss started the more information you can provide is the easiest way for others to understand your situation. , EzForJesus
Is it possible that you inadvertantly tossed out the grounding strap when you replaced the cap? That might be your problem...I would just hit a junk yard and grab another one. It's a cheap way (about $5) to see if that troubleshooting works. If not...the mid to late 80's and newer are known for electrical frustrations with that computerized stuff. Good luck!
You might want to check the timing. I'm not sure how to adjust it but you definitely need to see where it's at. Also how many miles are on it? If it is a lot the timing chain may have stretched and may need replacing.
Make sure that the wires are properly routed to the right cylinders. Also make sure that the wire snaps into place when connecting them both to the spark plugs and the distributor cap. If a wire is not properly seated to the plug or to the distributor cap the cylinder that the wire goes to can fail to fire properly. Believe it or not the voltage that needs to go across the tip of the spark plug is aroung 16k volts, not a whole lot of amperage but it insists it get plenty of volts. Improperly connected wires can realy play havoc with the way the engine runs.
