Should Water Pump be replaced before failing?

I have 102k on the clock on my 2005 5.7 and I have a small leak at the thermostat. I plan on switching out the thermostat and completing a coolant flush and I was wondering if it makes sense to replace the Water Pump at the same time.

Unless it's causing you issues, no. Check for leaks around the pump housing and listen for any whining. As long as your coolant has been changed during the recommended guidelines, the pump should be fine. Make sure you use HOAT coolant.

Don't fix it if it ain't broke.

I would change it. I've had two Ram 5.7's and both had water pump failures. One was at 88K miles and the other was close to 100k. Maintenance was done by the book. Much better to change it in a controlled environment than to be stranded on the side of road somewhere as happened to me

I'm on the fence with this. I agree with both posts. Why change a working part? Well, in this case, the tstat is being swapped, the coolant is getting drained, and a water pump isn't expensive. At 102K miles it could be on the verge of failure. It certainly wouldn't hurt to put a new one in while the other maintenance items are being addressed - it will not be as easy or convenient down the road.

I say do it all at once, change the pump on your terms versus failure down the road. Consider your lost time and inconvenience when it does go out.

I'd definitely change it, especially with that many miles on it. Heck, I changed mine on my Hemi WK at about 62000 miles when I changed the cam. I didn't change it on my Hemi LX though, when I did the cam change on it at about 50000 miles. It's much easier to do the job when you're already into and around the area. Nothing I hate worse than getting stranded somewhere. The good news though is that they usually don't fail without some warning.

I was thinking that if I am going to the trouble of replacing the coolant and switching out the Tstat then why not replace the water pump. I am afraid that I will get 5k down the road and the have to replace it and waste the new coolant that I just replaced. I guess that I will go ahead and replace it. I have had good luck with Omix-ADA parts in the past and I am replacing the OEM Tstat with their part and I wanted to see if anyone has used their Water Pump. http://www.omix-ada.com/water-pump-5...erokee-wk.html

I can get is from Amazon for $122 shipped.

I would just change it, mine didn't even make it to 80,000 and the last thing you want is for it to completely fail far from home.

I've personally never had a water pump fail in a vehicle I've ever owned. Although, I'm very meticulous about maintenance and no one does it but myself. Maybe I just get lucky?

Who am I to talk anyway, I purposely buy vehicles with problems just so I can fix them. I even work on friends' vehicles for the fun of it.

Preventative maintenance is better than spending '000's more fixing it after the fact. If anything it gives piece of mind!

If you change it with an OEM pump, and you do the gasket right, you could only benefit from it. If the old one looks good enough, you could always keep it as a short term spare. The hard part is draining the system, and if that's getting done anyway, why not?

Well I got some good news today. I took my Jeep into our local dealership because it would not go into 4WD lo, power steering making noise and dash lights occasionally flashing on and off. I got a call from my service rep and my warranty company is going to pay for the following:

1. New transfer case motor - 4wd low worked prior to the N23 recall.
2. New Power Steering pump and high pressure line
3. New light stalk
4. The best news of all, they found that my water pump was leaking and they are going to replace my water pump and thermostat.

I generally never buy warranties but this one has paid off. My warranty company has probably paid 7k worth of warranty work on my JGC. I would highly recommend Route 66 is you are going to get a car warranty. I believe that you can only purchase it through a credit union and I purchased mine through penfed.org https://www.penfed.org/Route-66-Extended-Warranty

They best thing about this warranty is that they do not inspect your vehicle prior to purchase and they also do not have a deductible. You pay taxes on parts instead. They have never questioned any of the work that was recommended.
