GMC Sierra

It is behind the starter.

200 hp. 300 ft/lbs torque.

A 1500 is a 1/2 ton truck. A 3500 is a one ton truck. The K represents that it is a 4wd truck so what you've got is a 1 and a 1/2, two wheel 4wd truck.

Talk about dumb questions!

Under the intake manifold above the fuel filter. Hard to see, hard to reach.

There are four ways to find a ratio.

1 A dealer can normally tell from the vin number.

2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement

info.

3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.

4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.

• Wow. ugh that's what I'm trying to figure out so ya. let me no when you get an answer on that.

If you get air flow to the defrost area -
Check for a vacuum leak either under hood or under dash
Check the operation of the vacuum operated motors under dash
Check the selector switch If no air flow to defrost - check for a plugged evaporator - remove blower motor and look or feel around

Yes!

The height of the 2013 GMC Sierra-3500HD is 6 ft. 5.4 in. (77.4 in.).

The Brake Booster is mounted on the firewall and the master cylinder is mounted on the booster. Look at the booster and you will see a very large vacuum line coming from the booster.

most likely that sounds like your problem>

There are more than one. Check the wires to the starter. A fusible link looks like a small soup can about half an inch long. There are usually two going to the starter, another in the small wire from the alternator and a couple near the firewall on the drivers side.

Two under the motor.

Go bu a Haynes Auto repair Manual.

Consult your local library's on line resources for auto repair.

Find out how much coolant your car holds. Buy thatamount of ready mix antifreeze or alf that amount in un-mixed antifreeze. Most locales in the continental US require a minimium or 50% water to 50% un pre-mixed coolant for protection against freezing and boiling.

On a cold engine with the battery disconnected.

Drain what coolant is in the engine; open (they are usually reverse threaded so turn it to the left to open it; right to close) the petcock valve located on the bottom of your radiator on either the left or right side tank. Drain coolant into a large bucket. Sometimes you have a petcock valve that has a little pipe on it; this is for a hose to better drain the radiatior.

The coolant in the engine will be draining through the lower radiator hose into the radiator and into your large bucxket. To hurry things along you might remove the lower raiator hose from the engine (expect an uncontrolled flood so have large drain pan in place to capture the coolant) or just remove the cap on the radiator.

After draining is complete make sure the petcock is closed and all hoses are re-installed and tight. Turn the vehicle heater on full "hot".

Refill the radiator slowly; the little cooling tubes on modern radiators run side to side so it will take a while to get all the air out. you'll see this happening with the bubbles that show up at the radiator filler neck.

When the bubbles stop that just means there is still air trapped in the radiator and the engine; so start the engine. You can see when the the thermostat opens by the way the water level goes down in the radiator filler neck; when this happenes start pouring more mixed coolant into the radiator. When the level stops falling and the radiator is full put the radiator cap back on tightly and fill your radiator from the radiator overflow tank to the "cold" mark. Run the engine till it's FULLY warm while you monitor the level in the overflow tank. Keep the fluid level on the cold mark; when it stops falling fill to hot mark. Dispose of your coolant in a environmentally safe way. Clean up; You're done.

Hmmm.... If you have hot water (coolant actually) entering the heater core and, with the heater on, get no heat and the return water is cold, it would follow that water is not

being circulated through the core. Either the core is plugged and needs to be flushed, the temp control cable is not operating the control on the heater core, or there may be a valve somewhere in the heat system which stops water from circulating through the heater core. This was done on some vehicles but I don't really know why. Perhaps to isolate the heating system from the AC system.

Are you sure the AC is not "stuck" on?

That's about the best I can do for you. Hopefully one of the others can

enlighten us further.

There are two pairs of speakers, a pair in the doors and a pair in the rear pillars. The door speakers are 6 1/2". I'm not sure of the rear speaker dimensions, but if you call Crutchfield or look at their site online, you can input your truck details and they will tell you what size the rear ones are.

For off road that is the rock bottom minimum. 12 wide would be recommended if your truck is to see the highway. Wheels that are too narrow make the tire crown in the middle of the tread. This causes only the center of the tire to contact the pavement. Which causes tires to wear out down the center, making tire replacement even sooner. Not the mention, not be able to hold the truck in the road. Most people think, okay I'll just let the air pressure down in my tires so they will get a flatter footprint. Yes, maybe, but you'll have to drop them so low that the pressure that you arrive at won't be safe nor applicable for highway or street travel. If a tire shop mounts your 14.5"s on your 10 wide wheels, make sure they don't rip the beads. These tires must be compressed pretty far down when mounting the top bead. Make sure the shop is qualified or express to the manager if they rip a bead, they bought the tire. BEFORE MOUNTING! Good Luck!

There is 1 on each side of the timing cover on the front of the engine block. You can not see them until you remove the alternator and bracket and then the power steering unit on the other side.

The IAT Sensor is attached to the Mass Air Flow Sensor that is attached to your air filter box.

It should be located in the engine compartment on the drivers side "Black Box". Good Luck and Remember.

You will need to take out the parts of the ignition and put in new parts. It is usually best to trust a mechanic to do this for you.

The 1992 GMC parking brake release lever can be found on the bottom of the dashboard. Pulling the lever towards the passenger compartment will release the parking brake.
