Video was excellent! Watched it, called Advance and got the pump....done in 2 hours and only cost me about $80 for everything. Saved me a few hundred easy....thanks man!

@@MrV2u is there a way it may leak to the transmission on a grand cherokee laredo 4.7l v8 2007? The water pump

[@MrV2u]

@@general14hayabusa anything that leaks; coolant, oil, or tranny fluid can travel all over the place as you drive. The water pump will drip down and as you drive, the coolant will flow all the way down and back. Look under your water pump and check the bottom of it and you will see a weep hole and it will be wet brother if it’s bad or going bad.

[@general14hayabusa]

@@MrV2u thank you, I’ve been told that some transmission lines go through the radiator on a jeep laredo 4.7l v8wk

[@MrV2u]

There is a transmission cooler that sits in front of the radiator. It will have two lines going into it from the transmission.

I went out to York Pa for a truck delivery and saw a place called;...U Pull It. As soon as I walked where the "GRAND CHEROKEES" were,...I just looked down on the ground and I started picking up the same water pump bolts.

Great made it look easy !! After I put it all back together my ac compressor was squealing when it would click on any suggestions why that would happen all the sudden is something to tight?

[@MrV2u]

Nothing should be to tight, the belt tensioner is set for the perfect pressure on the belt. Did you happen to spill any antifreeze on the belt. That would cause it to squeal. Take it for a test drive did it go away?

[@mikewk3026]

MrV2u I didn’t get antifreeze on the belt but it may have gotten elsewhere. I rinsed it all down and took it for a ride and its still squealing when the compressor kicks on . I’m hoping it just has something on the pulleys.. Thank you

[@mikewk3026]

It should move brother. You don’t need to loosen anything up first.

[@ickilla]

My jeep will leak a puddle underneath only when sitting over night hard to tell where it's coming from replaced the thermostat and rad cap still doing it and when at idle lately with the heat off the temp gage will climb up soon as I start moving it goes back down could that be a water pump?

[@MrV2u]

Do you know where the puddle forms? Center, left, right, front of motor rear of motor? If you look at the water pump is it wet in the bottom of it? Weeping?

Great video. I am trying to find out where my coolant is going. Overflow is empty. I don't smell any coolant. No coolant in the oil.

[@MrV2u]

Thanks for the feedback brother. Do you have a sweet smell inside the jeep? If you do you can have a failing heater core. The rug would be wet on the passenger side footwell. Do you see any dripping on the floor overnight? Is the bottom of the jeep soaked?

[@fyre8691]

@@MrV2u Yes the floor is wet. Thanks man. So it is a failing heater core? Thanks so much for replying.

[@MrV2u]

Being that it’s wet your going to need to replace that heater core brother. Sorry to be the bearer of bad news but that job is no joke and involves removing the entire dashboard. You won’t have heat soon if it didn’t go away yet. But if you want you can go under the hood find the two heater core lines going into the firewall. It will be on the passenger side remove the lines and join them together with a pipe and you can drive it like that without loosing coolant You just won’t have any heat whatsoever. Let me know how you make out brother or what you do.

[@mumenelshetwi6549]

After replacing water pump my 3.7 Laredo fires up and stalls if I don’t have my foot on accelerator ? Revs up till water gushes out of thermostat but dies when not reving? Any suggestions

[@MrV2u]

Coolant should never come out the thermostat housing. Also did you bleed the system of trapped air like I did in the video. It sounds to me like your overheating the engine. The truck shutting off is basically trying to save itself from over heating.

[@Urmom-ub6db]

Was all of the wetness and grime in that area because of the leaking water pump?

[@MrV2u]

That and going mudding and off roading didn’t help much lol. But that is what you get when it leaks. To pinpoint a leak really clean the motor well and check the weep hole under the water pump.

[@lovemekia6545]

How exactly would you know if your water pump is bad ?

[@MrV2u]

It will leak from the weep hole on the bottom, or start to squeal/squeak/groan, or you can pull the belt and grab the pulley and it will have play in it.

[@sasase2003]

Bro so.no RTV gasket required??

[@MrV2u]

Good question brother, on these motors it’s not required. You can see when I took it out there was none present. Some manufactures and years require rtv. But not for this application brother.

Thank you for the vid! I just purchased 2006 3.7 Jeep, 170,000 miles. How can I tell if the water pump needs replacing? Also, my EVIC system isnt working. The C/T, reset, step and menu buttons dont change anything when pressed. Any advice?

[@MrV2u]

Congrats on the purchase. Signs of a failing water pump: dripping/weeping under the pump at the weep hole, grinding noise coming from it, play in the pulley such as wobble or rocking it back and forth. As far as the evic system it could be a number of things. Do you have any check engine lights? I found a webpage that talks about the evic system. www.wkjeeps.com/wk_evic.htm Hope that helps some brother. Any further questions hit me up.

If the water pump is going bad it won’t circulate the coolant. But with your symptoms, I’d say you have a bad thermostat. Which is a easy fix to do your self. Make sure when you swap it out you bleed the system of air our you’ll overheat. Let me know how you make out brother.
