How to remove Water pump dodge ram 2500?

Answer 1

Fan shroud first, then alternator, then ac, then there are five bolts surrounding the water pump before removal. Make sure you have thermostat gasket because you will crack it on removal. There are several ways to make this job simpler depending on how much time you have on your hands. Removal of the radiator will save you alot of back breaking and bending. that's only four bolts and the cross member is only two. If you spend 20 bucks on a Chilton's it has step by step removal and replacement.

You will be stirring up a lot of engine gunk by doing this. Make sure you flush the system while you have it all apart. Strongly recommend a new thermostat while you have it all torn apart.

This is a single case O' beer job...per person

I came on and looked over these answers and was not happy with what I found.

Having just completed the job, here is how I did it. KEEP IN MIND: I have the 8.0 V10 in my Ram 2500.

It is VERY simple, much more so than any other water pump I have dealt with. (Only took three beers, but I'm a slow drinker.) The entire job should not take more than an hour and a half, including tool gathering and clean-up.

You'll need a standard metric socket set with an extension, a prybar, a 5/8 socket, a bucket, a good sized pair of pliers, and a large crescent wrench (1' or more). You will also need some petroleum jelly or similar lubricant. You'll need replacement radiator fluid, too. I'd just flushed my system, so I filtered mine through a washrag and re-used it.

It's common sense, but wait until the engine is cool before doing this job, a bath in hot radiator fluid is not pleasant. Also, be sure to pick up all your tools out of the engine compartment, nothing wrecks your day like having a tool rattle free, catch the fan and go through your radiator. (My Brother-in-law did this, and it was hilarious.)

Drain the radiator into the bucket. Remove radiator cap to get as much out as you can.

First, use the crescent wrench to loosen the nut holding the fan to the water pump. I wedged the prybar between the pulley and pump to keep pulley from turning. (I am not sure the size of this nut since I did not have the wrench for it.)

Be careful if you take fan all the way off to not get it into the radiator.

Then remove the radiator shroud by pulling the four screws. It won't come out yet.

Pull the fan out from between the radiator and the shroud. Then you'll be able to wiggle the shroud out no sweat.

Now use the 5/8 socket to torque the belt tensioner and remove the serpentine belt. (Check it over and replace it if needed.) My truck has the diagram sticker. If yours doesn't sketch it out on the parts box if you think you won't remember how it goes.

Remove the left and right hoses. There will be more fluid in the left one. The top won't come loose yet, so don't worry about it. Just get the clamp out of the way.

Remove all the bolts. The top star bolt is a bit of a pain as the socket gets caught, so do it last.

Now pull the pump loose from the engine and then the top hose.

Make sure there isn't any trash in the hole.

Take the new pump and lubricate where the hoses will attach. Also put some on the O-ring. (Otherwise it won't stay put. You don't want to be tightening the fourth bolt and see the O-ring laying on the ground under the truck.)

Re-attach the top hose. Stick the pump in the hole, make sure the O-ring is in there right. Replace the bolts. The two shorties go on the bottom, and the star on top. Use the tire method so you don't torque it down crooked.

Re-attach the other hoses.

Get the serpentine belt back on.

Wedge the shroud back in.

Slide the fan back in and get the nut started.

Secure the shroud in place.

Tighten the fan nut.

Replace the fluid. Restart engine and let it run a few minutes. Top of the fluid again and refill the spare tank.

How this helps make things easier.
