I have a 2000 jeep grand Cherokee 6 cylinder. It's been leaking fluid for over a year but I was only having to add to the reservoir every few months. Now I'm having to add to it every couple of weeks. I think it is the water pump but I'm not sure.

I hear they have these places you can go to find this type of stuff out...
|
|
my advice, is: get your junk fixed before you have to buy a motor. that's expensive, and no one's gonna buy any vehicle that don't run unless it's for $.10/dollar.
do what you want. |
|
If you have the tools and the space. pumps typically cost less than a 100 dollars and it shouldnt take more than an afternoon. But ive never worked on a jeep straight 6, only a 50 year old Chevy 215 I6. If you take it to a shop, I would guess 250-300.

$400 in my area at the shop.. I do 99% of my wrench turning so it would only be the pump, gasket and coolant..For a 2000 I would probably do a flush and change the belt and both hoses..

Shrouded mechanical fan + not a lot of space = taking a bunch of stuff off before you ever get to the WP. It can be done with a minimum of tools, but plan on the day if you're working alone. <== 2000 WJ 4.0, and the only major work I've had to do to the motor in 215k miles is change that water pump. ETA:Yeahboxes, some 00-01 Grands had issues with cracked heads. It might be worth having a mechanic check your vehicle out before you go changing parts out. |

Between $50 and $900 for labor on having it replaced. Depends on how much other stuff needs to come off to get to it.
Some cars practically need the engine pulled to replace it, like the Buick Skylark, which is the higher price replacement. With the quad 4 engines, if the water pump dies, you may as well put in a "fresh" used engine if the car is worth keeping at all. |
|
however much a pump and gasket cost and a case of beer... this is not hard to do. If you have 0 experience give said beer to friend who does..

I had to have it done at work last year and it was $300 at a little garage. (On a Chevy 3500 with 454)
I did one own my own truck last year for $37. (Not including the hoses I went ahead and replaced as long as I was in there) |
|
My wife who isn't particularly mechanically inclined did it on her Wrangler with only a little help from me. The wrangler uses the same I6.

Isolate the location of the leak before you start tearing up stuff.
Also how does your oil look? Also how many miles on this beast. Might want to preemptively change it regardless of if it is the source of your leak or not. |

(Not including the hoses I went ahead and replaced as long as I was in there) Yeh, that's an important aspect of the whole deal: Since you've already gone to the trouble of pulling all the pieces that block access to the water pump, why not replace all the other failure-prone items in the neighborhood, while you're at it? Things like: 1. The thermostat. 2. The fan and accessory belts. 3. Radiator and heater hoses. On a high-mileage vehicle, it might even be worthwhile to replace the radiator, fan clutch and belt tensioners. If just one afternoon of work and a couple hundred bucks in parts could eliminate 60-80 percent of the most likely failure points in your vehicle, wouldn't it be time and money well-spent? |

Check the condition of your oil carefully. If you have the 0331 cylinder head, there's a chance that the head is cracked and you are losing coolant into the crankcase. You can sometimes see the crack by looking in the oil fill cap.
Hopefully, it's just the water pump seeping. If so, it's not a difficult job. A moderately skilled hobbiest mechanic should be able to change the pump in a few hours. I'd suggest changing the thermostat at the same time. Make sure to give the hoses a good looking at. |
|
are you sure its leaking from the pump? make sure you locate the leak before you go tearing shit up and spending money on parts.

Go to autozone and buy a water pump. It will probably cost about $100. Get a tube of silicone sealant too.
Now replace it with the bad pump. If you need help there is a step by step guide somewhere on the internet. |

I think I need a new water pump too. I noticed some corrosion around the pump, and had to add more water than usual last week.

If you are asking this question, then I would recommend taking it to a reputable repair shop. You need to establish a relationship with the repair shop. It will save you money and aggravation in the long run. They know which part brands hold up and which ones do not as they have to warranty the work. If you don't have the skills to work on the car then it is best to pay someone to do the work.
You are looking for a Mom & Pop shop that have been in business a long time. Check out you church bulletin as these sort of shops often advertise in them; talk to other folks you know who pay to have their cars repaired. I can do the work myself, but I can also make a hell of a lot more in the same time period doing something else. |

water pumps are typically very easy to change if you have a socket set and a minor amount of mechanical ability.
ETA: just re-read your post, can you tell where it is leaking from???? If not, and you are only needing to add every couple of months there is this thing call evaporation that wrecks havoc in liquids (sorry for the tone, LOL). I have to add alittle to the overflow every couple of months in my ram and there is no leak, it is simple evaporation. How much antifreeze are you having to add at a time? J- |

Yeah, replace the thermostat. When I did my water pump I chose not to do the thermostat because I was fucking lazy, even though I knew I probably should. Six months it stuck and the truck overheated and left me stranded. |

Simple I did it on my Mom's Jeep to save her the mechanics fees.I also replaced the thermostat and radiator because they were also shot for a total of around 275.00.I'm a mechanic though.Listen its not that bad its a half water pump.Remove the serpentine belt then the fan or vica versa to keep the pulley from spinning.After you remove hoses from the pump.Remove the hardware holding the pump and clean the half surface.Its a paper gasket so don't put any other gook,silicone or gasket maker just spray adhesive to hold the gasket,if its the oring type put some light grease or vasaline to keep it in place then install the pump and torque the hardware to specs to make sure it goes on evenly and you don't end up breaking bolts.

J- I just changed the water pump in our 2003 Dodge Ram delivery van last week. It was a royal pain in the ass, and that whole van is a pile of horseshit. I wish a slow, tortuous death upon the entire engineering staff that designed that festering pile of ape anus. A bigger piece of unadulterated Taco Bell induced diarrhea on four wheels has never existed. That van is the pinnacle of AIDS infested engineering; thee preeminent example of a woefully inept, unsatisfactory and utterly insufficient education. That manufacturing "marvel" lacks even one minuscule redeeming quality. But anyway, changing a water pump isn't the end of the world if you have even an inkling of mechanical ability. |

dunno if its been mentioned yet. i started using a mechanic i found on craigslist. lotta small shops having hard times right now. DEEP discounts for professional work.

Must be different on your van. J- |

When 3/4ths of the engine is only accessible by taking apart the driver's compartment, you've got to know that working on it is going to suck. Gotcha, I can pretty much stand in my engine bay and the WP is right on the front of the engine about a 2 foot reach down. Different beasts it sounds like. J- |

If your gonna do it might wanna go ahead and replace the timing belt/chain while it is opened up.

If you have the extra money, it beats doing it all over again (, and probably in the middle of winter) when the timing belt fails. http://www.autozone.com/autozone/parts/Timing-Kit-component-Timing-Set/_/N-8znax?itemIdentifier=964096&_requestid=2483785 Timing Kit/component/Timing SetFor your 2000 Jeep Grand Cherokee 4WD 4.0L MFI 6cyl Price: $127.99 |

Dude seriously do it your self. Super easy and a great excuse to drink beer and mech on your rig
|
|
As noted, the actual replacement is usually pretty simple.
Getting to the damn thing is the problem. Use Permatex on the gaskets, and make sure the sealing surfaces are clean or the seal can be very iffy. Single edge razor blades are your friend it getting the surfaces clean. |
|
When water pumps go, its usually a large catastrophic leak that you would notice.
I would look more into blown head gasket, leaky radiator, or leaking water pump gasket. My personal opinion, is that it should cost should be around the price of parts, busted knuckles, and a sixer of beer. But I am a cheap bastard who refuses to pay others to work on my vehicles. Unless its something that the cost of tools would be way more than the price of the vehicle. I wouldnt be able to give you an accurate price for a mechanic. I havent used one in 13 years. |

My first mustang started out like that. I pulled one of the front drum brakes to inspect the shoes. I accidentally broke the shoe while putting the drum back on. After I was done fixing it. I had added disk brakes, undercoated the car, replaced the trans valve body, intake, carb, shifter, carpet, etc. All because I had to take parts off to get to what I was working on. |
