Also, I hope the person who decided to place a huge chunk of useless plastic on the back of the intake manifold gets a daily paper cut between their toes.

oil temp seems kind of high, it should be around 180 unless i'm wrong

Yeah, I've been noticing that. However, isn't it a computed temp? There's no physical oil temperature sensor....? Wouldn't a faulty oil pressure sensor (reading 124psi) contribute to an incorrect temperature reading?

Correct me if I'm wrong.


Either way, I have new parts on hand, waiting for some free time to install: radiator, radiator hoses, motor mount, EOC & TOC lines. More stuff on order as well, because who needs money?

How hard is it to change out the power steering hose, the forward most one that runs from the back of the reservoir to the rack?

Mine is looking corroded in the area where it transitions from hard tube to rubber.

good question, I just remember monitoring mine before just out of curiosity with the tech2 while I was having trouble with extra low mpg's and it would stay around 180 even if I was driving it very hard, my problem turned out to be bad cat's. I never considered what created the oil temperature reading, must be calculated somehow

In another thread someone described how the oil temp was calculated based on a table, or set of tables, that took it account a ton of engine readings from sensors, and extrapolated a temp from the tables.

I would think it'd just be easier to include a couple sensors, but you'd probably see some wild numbers for vehicles towing under high load, and it'd cause more issues from panicked drivers. I'm an idiot, so don't believe anything I guessed here.*

if anybody has the torque specs handy i need
3 hub bolts torque
axle nut torque (i think it's 165 or 185 not sure)
front brake caliper bracket torque (i think it's 180?)

Isn't torque spec like 180 ft lb

Plus with no caps those threads get rusty. Kroil or PB Blaster beforehand is your friend
i've had cap's on, anything on there is very minor or just dirt/grease I got both loose but man those were virgin, spinning the 1 hub I have off now it's got some noise not terrible but the new one is dead silent

Wasn't talking about wheel center caps, but the caps that cover the axle/nut

When I replaced the hubs on my 2011 I bought caps and installed them to help protect that area. Then the damn thing was totalled a month later, lol

It's not super pleasant but doable. The biggest ***** for me was getting the hose to seal at the rack. Buy gm seals. They are much better than the pos seals that come with the hoses. Mine leaked. Used gm the next round and so far so good. I believe I bought gates brand hoses.

26100863 is the part number for the gm seals

I was probably going to get the GM hose. If it doesn't come with seals now I know what part # to look for.

I think this is the hose in question....
