73-87chevytrucks.com - Suburban Project

[Captkaos]

After our initial bout with the TBI on the Burb, we moved to the next project:  Exhaust
Sunday July 1st: we removed the rotted tail pipe, muffler and what appears to be the original AC cat.
Monday July 2nd we started piecing together a replacement exhaust.  I used one of the 3" tails from a leftover X pipe kit, the Magnaflow muffler off my Jimmy that is currently undergoing a TPI conversion and a portion of the 6.0L LS motor with the cat.  We completed the system that evening.

Then we moved to the next project:  Air Conditioning
We converted the Burb over to 134a over the past week.  Last weekend we found out why the AC wasn't working.  We dyed the system and immediately found the compressor was leaking out of the housing, so we picked up a new compressor. 
Tuesday evening I removed the old compressor, cleaned up the Sepentine brackets and the front AC lines components were flushed out. 
Saturday July 7th I reinstalled the compressor and pulled the rear portion apart and flushed the rear portion out.
Sunday July 8th we pressurized the system and found a leaky O-ring/seal replace it.  Vac'd the system and installed the 134a.  The rear system is Seriously blowing cold air, but it appears there is some clearance issues with the fan as it is grinding some (no headliner right now)
The front of the system appears to have some vacuum issues as half the cold air is going to the floor vents.

I replaced the O2 sensor on the burb today and changed the oil for the first time since I got it.  I also found the transmission plug was dangling down so I reconnected it, and I also found that the fuel sending line was crimped behind the transmission crossmember.  I was hoping that would fix the sender problem, but it didn't.

Apparently there is a slow leak on the Burb's A/C.  After about 2 weeks of not driving it, the A/C isn't quite as cool anymore.  Discovered it when the fuel selector in my R10 went out and had to use the burb for backup..

What was wrong with this thing anyway I forgot?

[Captkaos]

Injector going bad and bad distributor.

[GhettoBurb]

what did you have to do to get the A.C. blowing through the correct vents? mine is mostly on the floor and I want to fix it before it gets too hot out. Thanx in advance.

[Captkaos]

I don't drive this alot and it got cold before I drove it again.  I am sure there is something amiss under the dash with the vacuum lines.

Bringing this one back up.  Within the last month I put the factory aluminum rims back on the truck and started driving it.  Also replaced the fuel pump and sending unit (with pics).  Also talked to a buddy about painting it this winter.  Gonna try and knock out some of the small issues off the list.
Broken ash tray, non working fuel gauge, removing old tint of the front windows, charging the AC again (not sure how far this will get with winter approaching), installing new carpet, more to come.

Looks a lot like my 91 Suburban. I'm probably going to part mine out though since all I'm doing is storing parts in it 

[Captkaos]

I was doing that for the past year, but change of plans.  Since my driver is about to go under for a transplant I wanted this for a backup to the Crew Cab.

Sunday September 5th, 2010:
Pulled out the worn front buckets and put in some cleaner replacements.

Monday September 6th, 2010:
replaced the fuel gauge in the dash with a replcement.  Positive is I know how much gas I got now, negative is the needle is bouncy.  Still more to come.

Wednesday September 8th, 2010:
Picked up some GILA FR200 Window Film Adhesive Remover Solution and remove all the tint from the driver and passenger windows.  MUCH better now.  While I was at it I Rainx'd all the outside glass.

let me know how you fix this, mine does the same... I was thinking my sender's reostat got rusty after sitting for 2yrs in empty tanks - but if it's a gage-thing I won't have to drop the tanks.

[Captkaos]

It is still just as ugly in the beginning, but I will get an updated one.

Will do Chip, I am wondering if I have a bad connection somewhere.

October 3,2010: Pulled the ashtray out to replace the missing springs and missing bumpers on the stops.  PO moved the stops so it flopped completely down.  Still need some work to make it smooth, but at least it isn't hanging all the way down.
Replaced both rear door striker/bushings to eliminate the annoying clunking down and make is shut easier.  MUCH better now.
Traced down the stereo speaker wiring trying to find out why I only have sound on the front driver out of the crappy stock radio, found both rear speakers are gone.  Looking into a new radio and speakers now.
