94 Chrysler Lebaron water pump removal

If this is the motor with the water pump is inside the timing cover, you will have to remove the mount.

There were three V-6 engines used in '94 and they are all very different. The 3.0L was the only V-6 used in the Plymouth Acclaim body style. There was a 3.3L and a 3.5L used in the Dodge Intrepid body style.

Normally I do not like or recommend Haynes or Chilton's manuals, but for this type of job they should be okay. You can find manufacturer's manuals on eBay for about a third of what they cost new. The dealership I worked for would borrow older service manuals to good customers, so you might consider that too.

There are also places online where you can buy a subscription for just your car for a year. AllData and Mitchell On-Demand are the two most shops use. Personally, I want to own a paper book I can put bookmarks in and keep forever.

Sure no problem, here you go.

Drain the cooling system.
Remove the mounting bolts for the pump.
Separate water pump from the inlet pipe that runs along the V of the engine and remove.
Clean all gasket and O-ring surfaces on pump and inlet pipe.
Install new O-ring on pipe (wet surface if necessary for assembly of pipe at ring).
Install new gasket on water pump and install pump inlet opening over water pipe, press assembly to cause water pipe insertion into pump housing.
Install pump to block mounting bolts and tighten to 20 foot-pounds.
Install timing belt, reassemble engine. Fill cooling system.

The proper procedure for installing the timing belt is important to get the timing correctly:
I assume that you have identified the location of the timing marks for the crankshaft and the two camshafts. The procedure then is:

1. Install timing belt on crankshaft sprocket first and while keeping belt tight on tension side install belt on front (radiator side) camshaft sprocket.
2. Then install on the water pump pulley and on the rear camshaft sprocket and finally on the timing belt tensioner.
3. Apply rotating force to the front camshaft sprocket in opposite direction to tension the belt tension side and check that all timing marks are lined up.
4. Install camshaft sprocket flange.
5. Loosen tensioner bolt and allow spring to tension timing belt.
6. Turn crankshaft two full turns smoothly, in clockwise direction only.
7. Again line up the timing marks on the sprockets and tighter the timing belt Tensioner locking bolt to 25 N-M (250 in-lbs).
8. Reassemble belt cover, engine bracket, insulator, crankshaft pulleys, accessories and drive belts in reverse order.

That is the direct quotation from the shop manual.
So those are the sources for doing the job. If you have not changed the timing belt in the past 60,000 miles it is prudent to do that at the time you do the water pump so as not to have to redo the job unnecessarily soon.

Let us know if you need anything else.

That's for the 3.0L engine. There's another important detail to be aware of. The tensioner pulley for the timing belt is spring-loaded. Loosen the bolt, retract the pulley, tighten the bolt to hold the pulley retracted while the belt is removed and replaced, but when it comes to tightening the belt, don't just loosen the bolt and let the spring do its thing. The pivot often sticks and doesn't let the spring apply enough pressure. Pry on the pulley to really tighten the belt. Remove the pry bar, then tighten the bolt. Rotate the crankshaft by hand two revolutions in the normal direction, then recheck the belt tightness and the timing marks.

There's a wall cast into the engine cover that prevents the timing belt from being able to drop down and jump a tooth on the crankshaft sprocket, and the belt has to be real loose to jump on a cam sprocket. If the belt is loose, it's not likely to jump time, but the water pump pulley will slip causing overheating with no other obvious cause.

Sure sounds like a thermostat issue. Look in the radiator to see if coolant is flowing while the engine is running and still cold. If you can't tell, try pinching off the upper radiator hose for a few minutes. If that causes the coolant temperature to go up, the thermostat is not sealing.

Are u looking at the Philips head screw
if so u have to remove the housing out and then u can remove it
inspect the tube and the O ring too

When the timing belt was removed, the spring pressure from some open valves pushed on the camshafts causing them to turn when you didn't see it. Luckily, the 3.0L engine is not an interference engine so no open valves will hit the pistons causing damage.

The procedure for installing the belt is best read from the service manual that includes very descriptive pictures, but basically, there is a pointer / tab cast into the housing, next to the crankshaft gear. Line up the mark on the crankshaft gear with that tab. Each camshaft sprocket has a line next to the teeth. Those lines must be lined up with the top of the engine block / bottom of the heads. Sorry, I can't remember if they go away from each other or toward each other. If the engine runs now but poorly, the camshafts will only be off by one or two teeth, so that will help you determine which way to line up the marks.

The cam sprockets will try to turn again so you'll have to hold them in position with a wrench. When the belt is slid on, it must be tight between the crank sprocket and front cam sprocket, and it must be tight between the two cam sprockets and water pump. All the slack must be between the crank sprocket and rear cam sprocket because that slack is going to be taken up by the tensioner pulley.

The tensioner pulley is spring-loaded but they can stick. Give it a poke to be sure it has the belt snugged up, then tighten the bolt. The final step is to use a wrench to turn the crankshaft pulley two complete revolutions in a clockwise, (normal) direction, then double check the belt tightness and the three timing marks. If you keep your fingers out of the way, you can run it before installing all the covers and engine mount to be sure it's right.

Behind the timing belt cover. The Tbelt drives it so you will need to take care on this. I recomed you replace belt at that time.
Good luck
