Do you have the service manual?

The water pump (3) on the world engine is attached to the water pump adapter on the front of the cylinder block.

The water pump is driven by the accessory drive belt. The water pump is connected to the water plenum by the return tube.

A quick flow test to determine if the water pump is working effectively is to check heater system for proper operation. A defective pump will not provide an adequate flow of heated coolant through the system.

WARNING: DO NOT REMOVE THE COOLING SYSTEM PRESSURE CAP WITH THE SYSTEM HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM COOLANT CAN OCCUR.

Another flow test to help determine water pump operation is as follows:


1. Remove cooling system pressure cap.
2. Remove a small amount of coolant from the system.
3. Start the engine and warm up until thermostat opens.
4. With the thermostat open and coolant level low, visually inspect for coolant flow. If flow is present, the water pump is pumping coolant through the system



REMOVAL

1. Remove the accessory drive belt (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELT - REMOVAL).
2. Drain engine coolant (Refer to 7 - COOLING - STANDARD PROCEDURE).
3. Raise vehicle (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE).
4. Remove accessory drive belt splash shield.
5. Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
6. Remove screws attaching water pump pulley (1). Remove pulley (1).
7. Remove water pump mounting bolts (2).
8. Remove water pump (3).


INSTALLATION

1. Position water pump assembly (3) into water pump housing (4).
2. Install mounting bolts (2). Tighten bolts to 24 N·m (212 in. lbs.).
3. Install water pump pulley (1). Tighten bolts to 9 N·m (791 in lbs.).
4. Install drive belt splash shield.
5. Lower vehicle.
6. Install accessory drive belt (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELT - INSTALLATION).
7. Connect battery negative terminal.
8. Fill cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE - FILLING COOLING SYSTEM).

 

Thank you very much Harold. I don't yet have a manual but I will be buying one soon enough.

 

he's Herald, i'm Harold

 

LMFAO! Sorry off topic warning: Reminds me of my last company Christmas party. Engineer(Graham) walks over to me with his wife at the bar. He thought I was a different tech due to never actually meeting me. He starts by saying "Hi. Lisa this is Graham.". Perfectly set himself up for my reply "No, your Graham. I'm Rylee." The red look on his face and the laughs me and his wife got from that were priceless.

Ok back on topic. Keep a drain pan handy for the coolant. I had to move my water pump to remove alternator and didn't seem to complicated to get it all loose.

 

Lol.

 

I'm thinking I should replace my alternator and belt pulley as well since it's better safe than sorry. I'm at 120k and had no other problems so far. Does anyone have those removal instructions they could post for me. Thanks

 

If the alternator is still good why change it? The removal of the alternator in the Patriot is a pain in the ass. You have to remove from below the car and to do so, you have to lower the A/c compressor.

Here is the link to service manual.

After the extraction of the file click first in the "INSTALL ME_SVGView.exe"

Then Open "CLICK ME TO START"

1. Open it with Internet Explorer 11
2. Allow blocked content
3. Go to setting and select F12 Developer Tools
4. In the menu below select Emulation
5. In document mode select 8

Select year and model and you're good to go

 

I have a bearing wearing out and I can't quite pinpoint if it's one of the three so I figure might as well do them all unless someone knows of a trick to figure out which is whining.

 

Thanks for the advice guys. Pulled alternator and pulled the decoupling pulley off and installed new pulley. Runs great!

 

Glad to hear!

 

Windows 7 has a free emulation mode for Windows XP if you have pro or above...

 

Windows 8.1 I am afraid as I had to buy a new cpomputer when the old CPU bit the dust.

 

2011 Jeep patriot, 2.4 liter engine. Is it possible to change thermostats?

 

Without having to replace water adaptor housing?
