Annual intake manifold bolt tightening sequence. I'm impressed by how many bolts out of the ten need to be torqued to spec. All were at the 1st pass of 44 in/lbs., but almost all were loose on the second 88in/lb. pass.

I also fixed the issue of my passenger side wiper fluid nozzle not spraying full chooch. I had to undo the two screws holding the plastic cowl down and pull all the hoses & connectors out to ****** overpressure their orifices with some lung-power. All good now.... only took 2 or 3 years to fix it.

Apparently the Mormon AI guarding our vocabulary won't allow the entirety of the Queen's English to be bestowed upon your virgin ears.

I meant to say or@lly. The admins should get out more.

there used to be some gm spray for the evap that was. meant to seal it so it didn't grow anything. but I've not been able to find it, just dead links. my driveway is steep and the water only drains out of the front. so it doesn't drain till next day when you back out. it's annoying and smells bad.

I try to click the ac button off a few minutes from home but I forget every time haha.

IF you're ac smelled bad, it would be worth $125 I suppose!

On my old toy sequoia (bought used) when I looked in there, the middle of the core face had about a 6" circle of grimy fuzz and pet hair. Lots of 409 and brush work and paper towels wrapped around a long brush to mop it all up. Unfortunately it didn't make my A/C any colder.. Doubt the spray cleaner will be as good at removing the hard gunk compared to physically wiping it. The blower fan gets a little dusty/grimy as well.

If you're pulling in forward, why not back in and let it drain that way?
