finally got the vibration gone ...... i hope

[nbenjamin]

So after about almost a year of the vibrating and trying to figure it out , i said screw it and changed the water pump . smooth as glass now . I'm pissed because when it started last year the first thing i did was change the water pump . the pump i put in was bad . it had a wobble but was stiff enough that was not noticeable .

i am curious now , should i change my thermostat and temp sensor ?? 05 with 167000 , god knows i have done everything else to .

Only if you get the dreaded P0128 code or the temp gauge isn't solidly on 210.

I can see where Roadie is coming from but in this case it probably wouldn't have been such a bad idea. Since you replaced the coolant after changing the pump you will need to do it again with a T-stat change. To do these separately would require a rehash of draining the coolant.
