2004 Envoy XL 5.3L V8

It can't be magical but I am haveing a deuce of a time getting the new AC belt on the AC Pulley after putting it around the Crankshaft Pulley, rotating the tensioner (clockwise) to it's fullest extent. The belt just will not slip over the AC Pulley. I have tried 2 different mfgrs of belts with the same results. There must be something I am missing. I make sure it is seated in the grooves on the CS Pulley, over the tensioner pulley (fully extended) and then try to fit it over the AC pulley. Any guidance will be much appreciated.

Don't know of a trick but here are the published instructions. Hope they somehow help.

 

5.3L Engine

 

A/C Compressor Belt

 

Remove the accessory drive belt.

Raise the vehicle.

Install a ratchet into the square opening of the air conditioning (A/C) belt tensioner.

Rotate the A/C belt tensioner clockwise in order to relieve tension on the belt.

Remove the A/C belt from the pulleys.

Slowly release the tension on the A/C belt tensioner.

Remove the ratchet from the A/C belt tensioner.

Clean and inspect the belt surfaces of all the pulleys.

 

To install:

 

Install the A/C belt around the crankshaft balancer.

Install a ratchet into the square opening of the A/C drive belt tensioner.

Rotate the A/C belt tensioner clockwise in order to relieve tension on the belt.

Install the A/C belt over the idler pulley.

Install the A/C belt around the A/C compressor pulley.

Slowly release the tension on the A/C belt tensioner.

Remove the ratchet from the A/C belt tensioner.

Inspect the A/C belt for proper installation and alignment.

Lower the vehicle.

Install the accessory drive belt.

put the belt over ac pulley and crank pulleyand tuck the belt in behind the tensioner pulley. use ratchet to pull down on the tensioner and lift belt up onto tensioner pulley. this is the way i do it at work as the directions from gm for this operation suck. you have to put the belt on the tensioner last

I will try that this morning. Thanks for the tip. I'll let you know if it worked for me.

 

IT WORKED!!

 

WAWA, you are a gem! For 2 days I've been trying it the way the instructions said (definition of insanity??!!??) and in 5 minutes with your help it is done! Thank you so much!

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
