Hi, I have a new motor for my 99 express 3500 5.7L and I was wondering if anyone out there has ever replaced the motor themselves. I have alot of experience fixing cars but never replaced motor. I figure its gonna be a bitch but would really like to do it myself for experience. Any help would be appreciated thanks

2003 Express A/C Blows Warm Air at idle by stack

My 2003 Express A/C blows warm air when parked and idling or stopped in traffic and the outside temp is above 90 or so. Gets cold again once vehicle is moving. Any other owners have the same issue? It has done it since I bought it new. I know there is a TSB on this subject for the GM pickups with the same 6.0L engine, but I see nothing about the Express or Savana. TSB calls for installing an auxiliary electric fan on the condenser.

15 passenger to a 12 passenger by ddanque

Hello everyone, this is sort of a technical pre-sale question that the dealerships here in Southern California, don't seem to have an answer. I can purchase a 15 seater, but would really want a 12 seater, but all of the dealers with 12 seater don't have the other options, that the 15 seater carry. So can I remove one of the 3 seater, and move the 4 seater bench seater to the next to the last position?
 
In addition, which do you prefer, the hinged or sliding door.
 
Thanks
 
Denny

Got the coolant and the hose, now I need to find where to plug in... I can see the high point connection. Where is the low point?

Was there ever a resolution to this? My 02 Yukon is doing the EXACT same thing. I can't find resolution in the boards.
 
Thanks.

Excerpt from TSB below, mentions 02 Yukon. You should be able to go to the dealer and have them pull up the TSB #01-01-39-004, also try www.alldatadiy.com
 
A/C Not Cold Enough, A/C Blows Warm Air with Vehicle at Extended Idle (Install Auxialiary Electric Coolant Fan) #01-01-39-004
A/C Not Cold Enough, A/C Blows Warm Air with Vehicle at Extended Idle (Install Auxiliary Electric Coolant Fan)
2000-2002 Chevrolet and GMC C/K Utility Models (Tahoe, Suburban, Yukon, Yukon XL)
 
2002 Cadillac Escalade
 
With 6.0L Engine (VINs U, N -- RPOs LQ4, LQ9)
 
Condition
Some customers may comment that the A/C stops cooling and blows warm air when the vehicle is idling for an extended period of time such as sitting in traffic.
 
Cause
Inadequate airflow over the condenser may cause this condition.
 
Correction
The addition of an auxiliary fan in front of the condenser radiator assembly may help to alleviate this condition. The coolant fan will come on each time the A/C compressor is commanded on by the PCM. This fan will create a roaring sound when operating.
