When to replace water pump and timing belt?

Ive heard a lot of different answers on this one. What is yall's recommendation on when to change and about what the cost would be if you were to do it yourself?

 

If you just bought it and have no clue when the PO did it, do it
If you haven't been following intervals, do it
If you have to ask, do it

 

It is recommended at 90,000 or 100,000 and or 10 years, whichever comes first. I did mine at 120,000 and 16 years old, and it was still okay, but pushing it - the belt looked a little dry rotted with small cracks in it, so I would not recommend stretching it out that long.
I had it done at the dealer so I don't know what it would cost to do it yourself - certainly only a fraction of the $1,200 I paid. I had all the other belts, radiator hoses, thermostat, waterpump, idler pullies and some main oil seal that was down there replaced at the same time. Still, labor was the majority of the cost.

 

Agree with above ^
I would not do it any later than 100k miles. If the water pump is leaking prior to 100K, do them both then.

Just did mine along with water pump for the cost of the kit and coolant ($250-ish).
Super easy with a manual tranny, no special tools needed.

 

Right here is the answer. I did it at 112K miles, and 14 years. The belts were o.k., but the water pump was on it's way out.

 

I did mine for tha first time in 2012. Truck had 206,000. Belt was fine, but the water pump was on its way out. I wouldn't suggest going that long.......

 

Water pumps usually start leaking out the weep hole or the bearings will squeal. Giving you advance warning.
Take the fan belts off and feel for play in the bearing. You'll get an idea if the end is near.

 

Did mine immediately after buying my truck at 200k as well. Belt looked ok and given how well the previous owner took care of the truck it might have been a little tempting to assume it had been done, but since I didn't have any conclusive service records, I wasn't about to roll the dice with winter coming up.

 

Can you share where you got the kit from? Last I checked the cheapest was $300, and I think it was missing a few things.

*Edit: Nevermind I see some now that are pretty close to that.

 

You should definitely replace the water pump when doing it, leak or no leak.

 

I think that all applies to 3.4l engine. I have 2.7 so timing belt does not apply. And because my water pump does not leak, bearing don't squeal so I'm not touching it. 318k miles and 23 years now. Damn, this engine is so good.

 

Mine was done when I bought the truck at 130,000 miles...not sure about before that.

After 90,000 more miles I replaced it again at 220,000 miles. I think I spent about $380 for all OEM stuff. My AC condensor grenaded itself so I replaced all the AC components while I was at. Total for both was $900 and took 13 hours.
