Water pumps ???

[norsman]

Looks like my water pump is leaking Is that a big job ?? I've replaced several water pumps in my life just never on a hemi .Any tricks to make this go easy ??

It's just a textbook waterpump change. Make sure you use HOAT coolant...no green stuff. Might as well replace your belt while you have it off.

Forgive me if this is ignorant, but why not the green stuff?

The cooling systems on our trucks is designed to use HOAT...HOAT is Hybrid Organic Acid Technology...the ONLY way to properly use the conventional coolant is to COMPLETELY flush out the entire cooling system. If you don't do so, the acids in the HOAT will react with the acids in the conventional, causing problems...

Well looks like i screwed that up. how long does it take to screw stuff up?

It will happen overtime, your cooling system will sludge up.

Been thinking about putting in a new water pump in my truck. It isnt bad yet, i just wanna change it out befor it goes bad lol.

I had a 2001 sebring with the 2.7L engine in it. The water pump went bad on it, and it was probably the hardest job to replace it. They put it in the damn engine... And as i was selling the car i did some research and apparently when the water pump goes bad it usually means the timing belt was hitting it. Which usually causes the motor to just go bad. Luckily that didnt happen to us...

When i did my radiator flush i went to the dealership and it was only like $13/gallon for the coolant.

Yes, but the entire cooling system needs to be flushed...you must get all the HOAT coolant out, or risk it interacting with the green stuff and sludging up. Valvoline makes a HOAT coolant in their Zerex brand called G-05...NAPA stocks it.

It's the same way with the wife's PT Cruiser...I dread the day it goes out.

How many miles do these water pumps usually go before they wear out?

 

[KGBIGCOUNTRY]

100k on the 05 with no issues knock on wood for the pump

On the other end of the spectrum I'm at 95k miles and on my 4th water pump. First one went out at about 60k miles - bearings crapped out. Second one went out at about 80k miles - was really just leaking so I replaced it. Third one went out at 80k and 20 miles. LOL. It was a reman'd pump and it grenaded the day after I replaced it. Lesson learned...buy new water pumps!!
