Funny, I just did my water pump, thermostat upper and lower hoses this past December. Water pump had a small drip at 269K. Water pump isnt bad at all. removing the alternator gives you full access to the pump and thermostat. The lower pump bolt is just a lil tricky.ColonelPanic wrote: ↑Mon Jun 15, 2020 1:51 pmYesterday I was going to replace the thermostat, the radiator hoses and heater hoses and flush the coolant... Then I thought to myself I should probably see how the 17 year old water pump was doing since I'd be working right next to it anyway. It's not leaking, but the pulley is looking a little rusty crusty. Took the belt off and spun the pulley - uh yeah, a little rough.
Ordered an Aisin pump from Amazon and put a soon to expire O'reilly coupon toward a new serpentine belt for good measure. Guess I'll be doing all of that next weekend...
And oh, replaced the radio antenna again. The lower portion of the antenna just likes to disintegrate from being out in the weather all the time. Used OEM last time but went with a lesser expensive one from ebay this time.
Thats good to hear ! Im in the middle of tracing down a vibration at idle as well. I think my problem was a mix of old/new mounts...so I redoing them all. I replaced the sides and front mount and that reduced the vibration dramatically. I still have a bit of vibration left....hoping the rear mount solves the rest. Its been almost 2 months and I have to to replace the rear mount, but Im going to pay someone to do it. Hope I didnt wait too long and ruin the new mounts again This is driving me nuts. The vibe has never been a smooth idling car, so anything more than that in unbearable. This is actually the first time I wanna get rid of the car and I have owned it for 14 yearsColonelPanic wrote: ↑Sat Mar 06, 2021 7:22 pmI solved the Vibe's unbearable vibin' at idle today! Not surprise here, it was the aftermarket front transmission mount which actually made things worse when I installed it a year ago. Installed a new OE ACDelco mount (P/N 88969066) and wow, what a difference. In gear/brakes applied/at warm idle speed, the only vibrations noticeable are nothing more than what I'd expect out of this engine (we all know the 1ZZ was hardly a marvel of refinement.) She's such a joy to drive now that I didn't even mind getting stuck at every red light during my test drive.
Beck Arnley aftermarket mount on left / GM on the right.
I'm no NVH engineer, but it seems the Beck Arnley mount was just far too stiff. The rubber section in the center of the aftermarket mount has hardly any give to it compared to the new OE mount which will flex without too much effort. When I pulled the original mount a year ago I had noticed similar flexing but thought it was because the mount was just worn out. ¯\_(ツ)_/¯ Oh well - I would say it's a bummer that I wasted money on the first mount and that I had to do the job again, but the smoothness more than makes up for that.
In other news, it has been over a year since the tires were rotated (2500 miles ago, LOL) so I took care of that. Greased up the tie rod ends and sway bar links. Sprayed some fluid film on random places.
And I switched out the sort-of dim cool white LED's in the dome lights to some warm white ones.
If I had to rate it on a scale from 1-10, probably about 11. This month we've put more miles on the car than usual and so far things are still quite smooth. Very happy with the way things have turned out.cptnsolo77 wrote: As a side note how bad was the vibration with that one bad mount ? Its amazing that one mount solved your issue !
