Q: Why has my 1991 GMC Sierra 1500 stopped shifting into 4 wheel drive?
Our truck has had trouble shifting into 4 wheel drive for a while, but just recently it quit entirely. When we bought the truck used, the previous owner said there was a part in the transfer that if replaced, would solve the problem. Does anyone know what part this might be, or another possible solution, with the winter starting up, 4 wheel drive would be very useful here in michigan.

A: Does your manual shift lever go into 4H, and if so does you 4 wheel light come on? if it shifts to 4h but the light doesn’t come on its the actuator in the front diff. I just had mine go out on me last week I have a 1990. The actuator is about $90 from summit or autozone and is a 5 minute fix if you want to start there

Q: How do I remove the interior door panel from a 2003 GMC Sierra 1500?
I am upgrading my audio system in my truck and I want to replace the factory speakers in the door. I just need some instructions as to how to remove the door panel. My truck is basic on the door. No power locks or power windows.

A: Check LMCTruck.com they will give you a detailed exploded view of the door.

Q: How hard is it to replace the heater core on a 1995 GMC Sierra 1500?
It has the regular cab with air conditioning and a 5.7 liter engine.

A: The heater box in that is the same as the 1988-1998 Chevrolet C/K trucks and the repair manual will instruct you to remove the heater box which requires lifting the passenger side dash. But that is unnecessary and is a huge waste of time because the job can be shortcutted. The heater core on that is accessed by removing the bottom cover on heater box and the reason the repair manual instructs to remove the heater box is because removing and replacing a screw on the firewall side of the bottom lid is problematic with the heater box in the vehicle. But removing it with the heater box in the vehicle is doable. It is replacing it when reinstalling the bottom lid which is really tough but most mechanics will not bother to replace it when shortcutting the heater core replacement.

1. Disconnect the heater hoses at the firewall under the hood.

2. Remove the passenger side kick panel and door sill and pull the carpet and padding back. This is necessary not only to avoid spilling coolant on the carpet when removing the heater core but also because the thickness of the carpet and padding closes the gap between the heater box and firewall and obstructs access to the screws on the firewall side of the bottom lid.

3. Remove the 6 screws securing the heater box bottom lid. One screw on the firewall side of the bottom lid is recessed in a well between the heater core inlet and outlet tubes and the other 5 screws are on the lip of the bottom lid, 1 on the front lip, 1 on the right lip, 2 on the left lip, and 1 on the firewall side lip. It is the 1 on the firewall side lip which will be a bear to access but removing it is doable using a shop light and a mirror to see it and that is the 1 which most mechanics will not bother to replace when reinstalling the bottom lid.

4. Remove the bottom lid.

5. Remove the screw and clip which secures the heater core and remove the heater core.

Q: How can i make my gmc sierra 1500 go faster?
It is a 315hp and i want it to have more power and go faster without getting a new engine. can i get superchargers or turbo’s for it? what do you think i can do?
it is an 07 model..

A: I own a shop, build race engines, and own a race car & truck. There are many things one can do to make it go faster. I would suggest this site
www.chevyhiperformance.com
and you should be able to fully see all the things you can do to upgrade your engine. Yes you can get a super charger for it, but you are talking a lot of money. I will agree with the headers, exhaust, cold air intake, hotter ignition system, and programer for the computer. You could see as much as 100-150 horsepower increase over stock by just adding these components. One thing about power, we all have a need for speed, and no matter how much power we have, we will always want more. You might consider installing a gear in the rear end, as this will get it going a lot quicker. You would be suprised at what 315 horses will do when you get it all to the ground. If you have an automatic, you could install a mild stall converter, and get into the power band a lot quicker.
Part 2:
My brother has one of these, and he purchased a programer that sits on the dash. He can dial in his power with it. “What a difference”!!! The truck will now lay your @ss in the back seat when he slams the pedal to the floor. He has done nothing more to the truck other than the programer. I am convinced this thing makes all the difference in the world. There is a company called “Procharger” that makes one that will give it all kinds of power. I take a magazine “Chevy High Performance” and in the new up coming December issue (which I just got in the mail) they address this exact issue. An article called “Dyno Freak” shows a low profile Procharger that is making jaw droping numbers on the dyno. You might be able to read the article on their website
www.chevyhiperformance.com
Believe it or not, but I have never seen these kind of numbers from a charger that will fit under the hood. You might want to check this out.
Glad to help out, Good Luck!!!

i have a 2006 gmc sierra 1500 5.3 am looking to laptop it where do i go to do that? looking for performance im in sacramento ca what will it cost? what will i need to buy?

A: You will need a laptop, of course, and a GM tuning suite. I prefer EFI Live, it has countless tables you can modify. Cost is about $800 if you want to do it yourself, or you can find a GM LS (Corvette, Camaro, Firebird/Trans Am) based tuner in your area for around $400 or so.

After a long drive the water in my radiator come back up to the tank where the water all at and over flows it which causes it to all bleed out through a value and leaves me without water. Which then later causes my engine to over heat. How to I stop this?
After a long drive the water in my radiator come back up to the tank where the water all at and over flows it which causes it to all bleed out through a value and leaves me without water. Which then later causes my engine to over heat. How to I stop this? I’ve already flushed the radiator and changed the thermostat I also changed the water bump yet it still flushes water out
I have used antifreeze but it flushes it out continually that its hard to keep buying antifreeze over and over when the engine keeps letting it all overflow out. I only use water because its easier to get access to and it doesn’t cost as much as antifreeze

A: replace the thermostat check for swollen hoses goodluck
