Hello out there. I am new to this site, just fount it to be honest. Anyways I was looking up for the (XLT model) 3.0L engine diagram so I know what I am doing when I go to changing my water pump, thermostat, and power steering pump. All three at once, one at time though. Anyhow, I was getting gas and my old friends said to me, 'Hey T, get out come over here and look at your ride from here.' Well when I saw it, it was pouring antifreeze out the side/bottom of engine. Popped hood and looked good to see where it leaking from. Well, it was on the driver side right in front of (or underneath) the timing chain/crankshaft like it was coming from the thermostat. So I need the diagram for the engine and cooling system if it available too. Also, if any advice about exactly where that leak came from would be appreciated. I am thinking the thermostat but I could be wrong. And also the coolant and engine light came on as I was on way home which is just about one and half miles from where I live.

Thank you for your time!

Hello and thanks for using 2carpros.com. I want to help the best I can, but there is not one picture of the entire cooling system. Therefore, I will start with the water pump instructions for removal and replacement and include as many pictures of it as I can.

Water Pump-3.0L (4V)

Removal and Installation
Drain the engine cooling system.
Remove the air cleaner outlet tube.
Remove the water pump belt tensioner, if equipped.
Disconnect the three hoses.
Remove the bolts and the water pump assembly.
Separate the water pump from the water pump housing.
NOTE: Clean and inspect the sealing surfaces.
To install, reverse the removal procedure.

Here are the general directions for replacement.

Before replacing anything, I would recommend pressure checking the system to determine exactly where the leak is coming from. Here are the directions you will need. Additionally, you will need the gauge. Most parts stores will lend you one,

I hope this helps. If you find it is not the pump and need directions for a different component, let us know.

Take care,
Joe

Hey guys, everything on the installation of all that went well. Now the only problem I have is that temperature light keeps coming on and it will go off for awhile then back on again. The only thing my cousin and I can think of that is making that light come like that is that there is some air in it someplace, so we just need to figure out how to bleed the air out it. So if you know of the easiest way to (or any way for that matter because that light is messing with me bad!) To bleed out any air out of that, let me know!
Also, just so you know, it has not been getting hot or anything. I felt the radiator after about a ten mile drive and it was cool as a breeze. So it has to be air inside it, I just cannot figure out how to get it out yet.

Thanks for your time (again),
Travis

This is the factory process:
Make sure the coolant tank is at the full mark. Turn the heat on full with it blowing out the dash vents. Start the engine and let it idle. Check that you have heat at the vents. If no heat then you are low on coolant. If you have heat then let the engine idle. Check that the upper radiator hose is heating up, If yes then let it idle until it reaches operating temperature.
Shut it off and let it cool, check the coolant level.

If it still stays cold then something is wrong. Then you might want to try a vacu-fill to fill the system. Some places will have them as rental/loaner tools.
