Bad waterpump?

The Story
So 2 days ago (sunday) it was like -10F (did not start the jeep at all this day)

yesterday mourning when i started my jeep (-3F) it started a bit hard. Sounded like a bad battery.. pretty normal in the cold. Nothing noticeable. My drive to work is about 5 minutes so the jeep never has a chance to fully warm up (maybe its at full temp at about half a minute from my job). I let it warm up in the mourning every mourning till the temperature needle moves up halfway on the letter and then i go.

The problem

So today i went to work. No problems at all. I got to work and parked it. At work i had to drive to another place so i started my jeep and turned the heat on. It went hot, then it went freezing cold. Half a minute later it got warm again so i thought maybe the heater core didnt warm up yet so i continued on. Down the road my temp gauge was fully warmed up and started going up a bit and then went down to 210 again.

Well i got to the other place with no noticeable problems after that. On the way back i checked the coolant level.. pretty low so i went to the gas station to get some coolant and filled it up (both radiator and the coolant bottle)

On the way back same thing again with the heat.. it went completely cold for a minute then went warm again and stayed warm till i got back to my work which lead me to believe it was just low coolant.

The leak
I got to my work building.. Get out of the jeep to find coolant leaking around the drivers side of the engine however it seemed like it was leaking from the front, going between the cracks where the crankshaft case bolts to the block and then dripping at the edge where the engine meets the transmission. (No not coming from between the cracks, just going through them like water through aqueducts)

We got a tons of snow today (all day) so on the snow underneath the jeep i saw 1 smaller leak in the front of the engine and the huge leak in the back where the coolant was coming from the front.

I have 1" tcase drop to explain the uneven levels of the engine. Also i do not smell any coolant at all when i have the heat on nor do i have coolant leaking inside the jeep by my feet.

The jeep is currently at my mechanics shop. I cannot do the repair since its about a foot of snow, its about -5F and at last i do not have a garage.

could be a bad water pump it's most likely coming from the weep hole on the pump.here are some pics of when i did my pump.
My progress so far on my water pump.

same problem
i just got a hi flow pump from summit yesterday. i grabbed a turbo city/rock-it high flow housing and 180 thermostat while i was at it. ill let ya know if that fixes it... i dont know about the heat...i have that problem too and im hoping this fixes it...(the air pressure coming out of the vents is noticablly lower too...) good luck with yours!

I kick my self in the back every time i think about it. I should have replaced the coolant after the dealer replaced my radiator. They put in crappy coolant.

When it was leaking today.. it was nice and brown. far from the usual neon green or bright ATF red..

like i said man i kick my self in the back every time.

see the funny thning was when my jeep was off at the gas station and i was filling up with coolant, there was no noticeable leak, as soon as i started it and pressurized it, it started leaking.. however the fact that the coolant was low (since it was leaking).. it did not take any coolant from the reserve bottle.

if its a leak because of a bad hose, i would be jumping from joy although it would explain the cold heater problem would it?

well what you need to try and do it over heat it but with t being -20 out everyday it is damn near impossible.

IF you can't get it to over heat then it is not the pump. It is something else. If it over heats it is the pump.

thats not going to tell you anything. if half the fluid is on the ground, itll overheat regardless of water pump. the lack of heat was probably because it was low on coolant there was air in the heater core. most of the time when i've seen a water pump go out, itll leak a little, but ive never seen one just gush out. i did have one howl like a banshee and not leak at all.

the next big problem is that the temp sensor is located on the end of the chain when all the coolant is coming out. There is no sensor inside the engine so the water pump can be frozen. Not pumping any fluid and the sensor is just sitting there in the corner measuring that coolant and not the real temp of the coolant inside the engine.

usually if the waterpump seizes up, you'll hear some uber belt squeeling

Trip.. A lot of people had a rough year this year.. I mad not even half of what I mad a couple years ago.. or the year before this.. Life sucks when you need money.lol

As for the leak.. I recommend you get a pressure pump, Buy it and return it (up to you to keep it). and find out where the leak is coming from first.

don't wast your money replacing parts just yet. if you cant find the leak take the belt off and spin the pump by hand to feel if there is any play or bad bearing noise. if so then replace the pump and go on from there.

I had a intermittent problem just like you not to long ago on a ford focus.. I would drove it for a month and it did not overheat, until i drove 50 miles back from san francisco. 7 made 7 stops. then decided to call a friend and left the car there. the next day I went to check it out with some tools and did not find anything wrong. drove it home 20 miles and nothing wrong at all.. So I just replaced the thermostat and nothing wrong ever since.. I sold the car and checked with the new owner a month later still nothing; hes happy with it.

Hope the story was entertaining and helped a but.

Maybe you forgot to turn on your e-fan!! LOL.. Mines working great without the switch.

fan on, heater on high.. nada man, barely got the temp gauge to show about 210.. i'm pretty sure that wasnt the right temp too.

like i said i really cant work on it my self since i have no place to work on it. Its currently snowing again.. It cant fit in my girlfriends garage either so.. lol

im getting a 180 thermostat for my car when i get a predator for it.. (it actually comes with it)

does changing the thermostat from 210 to 180 have any positive affects on a jeep?

is that why jet and hypertech offer then with their chips/programmers to increase performance?

Hypertech:
"From the laws of Physics, we know that cooler air is denser than warmer air, and since horsepower increases as the amount of air and fuel burned increases, cooler air makes more power. Replacing the factory thermostat with the Hypertech low-temp PowerStat will allow the engine to run cooler, making more power and reducing the engine's tendency to detonate. Detonation, usually producing audible pinging or even knocking sounds, refers to the spontaneous explosion of the unburned air/fuel mixture in the combustion chamber. Detonation violently ends the normal combustion process, reduces power, and can severely damage the engine.

To complete your performance package, Hypertech recommends the use of a low-temp thermostat to compliment the performance tuning found in the Hypertech Power Tuning products. A PowerStat low-temp thermostat improves performance in two ways: first by inducing less heat into the intake air and second by reducing the engine's tendency to detonate.

Replaces factory thermostat
No modifications required
Realize full potential of Hypertech Power Tuning
50-State Emissions-legal when used with Hypertech Power Tuning"

Jet:
"Reduced engine temperatures add life to your engine and provide a denser air/fuel mixture which helps produce more horsepower.

Consistent control of engine temperature allows an engine to operate at its peak efficiency no matter what the driving conditions. The factory 195 degree thermostat simply cycles open and closed, this reduces cooling efficiency in any engine. With the JET 180 degree thermostat you get consistent engine cooling and a precise metering of water throughout the engine. Constructed of stainless steel the JET Thermostat offers a lifetime warranty."


TurboCity/Rock-It:
"Hi-flow thermostats are specially built to provide increased coolant flow are higher engine temperatures. Larger openings and more travel result in better temperature control. Available in 160F and 180F . Use 160F for more power, use 180F for fuel economy."

from what i know their chips add a little more fuel. The lower temp coolant thermostat is new to me however i can see what they mean especially on vehicles with watercooled throttle bodies and intake manifolds. When u do an intake, exhaust and expand the throttle body, the engine gets more air however the computer does not see that since the air meter uses temp to measure air flow instead of really counting how much air is going in.

So the computer gets its data from the blind man about the visual appearance of the thief.

our wranglers from the factory seem to be made a little rich in the lower rpm and lean in the higher rpms. In the lower rpm the cooler air flow is just perfect however you get even leaner when you rev that puppy up so the chip adds a bit more fuel.. helping out with proper combustion.

This is the main reason why you have people crying that OOHH THE INTAKE DID NOTHING OR MY EXHAUST DID NOTHING OR THOSE COMPUTERS ARE SCAMS.. they do one which is not really noticeable under the butt dyno and they go out calling it a scam.

i wasnt talking about chipping the jeep.. from what i read at the charger forums the chips do make the chargers better.. especially keeps it from auto shifting when using the flipstick

alright back on story, the guy at the shop called yesterday confirming that it was the water pump leaking. Tomorrow my rig is suppose to be ready. While he was at it, he will replace the serpentine belt. 471 bucks all together out the door.
