Top 20 1992 GMC Sierra - Page 4 Questions & Answers

Common causes for over heating are listed below:

1. Lack of coolant
2. Leaking radiator (usually on a seam)
3. Leaking coolant line (usually but not always around the fitting)
4. Bad thermostat - prevents sufficient coolant from entering the system from the reservoir
5. Bad waterpump (will usually leak but not always, can be bad waterpump bearing)

change the grounhed wire or run a second ground directly to the bolt on one of one of the seats as this goes directly to frame

There are two ways to check this problem. With engine off, grab fan and spin it. If it takes a minute or so to stop, or feels easy to spin, the clutch may be bad. The other way to check is to start engine, and using a long metal pipe (or lug wrench) insert into fan. If it stops spinning, then the clutch is bad. If using the second method, be certain that engine is idling...DO NOT ACCELERATE!!!

try plugging the wires back and check your fuses

I would say the problem is inside the radio itself. I have no idea if anyone repairs these units anymore or if any good used ones are available.

It should be in the fuse panel.

To the chassis somewhere or maybe the engine. Follow it from the battery to find the point of connection.

Hello
In the picture below is number 14 the block you refer to?

Hi!!
Here is where the bleeder screw is on the SLAVE/SECONDARY cylinder and the instructions to bleed the system.
Hydraulic System GMC SIERRA 1988-95 Models

• Fill the clutch master cylinder with the proper grade and type fluid. Raise and support the vehicle safely.
• Remove the slave cylinder retaining bolts. Hold the cylinder at about 45° angle with the bleeder at the highest point.
• Have and assistant fully depress the clutch pedal. Open the bleeder screw. Repeat until all air is expelled from the system.
• Be sure that the fluid level remains full in the clutch master cylinder throughout the bleeding procedure.
• Install the slave cylinder.

Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

If you have got taller tires on then what it came with from the factory it will definitly throw the speedometer off.You will need it to be recalibrated for a different speedometer gear put in the transmission.This will correct the odometer

1994 4.3
or this

There should be a schematic on the lid of the fuse box that tells you what each fuse is for, and the size of the fuse.

On the side of the transmission.

Let us deal with the two very separate problems here.
The problem with the blower motor is that the blower motor speed control resistor is burned out, when this happens all you will have is high speed setting. The blower motor speed control resistor is located right next to the blower motor in the air ducting. It has an electrical connector going to it with 3 wires, the resistor is roughly oval shaped and would easily fit in the palm of your hand. It is held into the air duct work by two screws. See picture below.


I will deal with the radio issue in a separate reply

IF ORIGINAL STEREO SHOULD BE IN FUSE BOX UNDER DASH DRIVERS SIDE

The stabilizer bar bushing are rubber bushing that wrap around the stabilizer bar. The bushings are located where the stabilizer attaches to the body and wheel control arms. A service manual from an auto parts store will provide exact location.

Look under the hood for the first fuse box, located on the driver's side. check the headlight relay it may be bad. all the relays are in this fuse box.

Hit the the bottom of the starter motor with a hammer while someone is holding the switch in the crank psition.If it cranks then you need a starter.Also you can check with a test light or meter and see if thereis voltage at the starter solenoid.The big wire shold always have voltage and the small wire should only have voltage when the switch is in the crank position.Good luck.

manual trans. dont have dipsticks... there is a pull on side of trans. half up side or more u take it out and if fluid comes out its full or stick finger in to c how low.... if cant fell fluid with finger its pretty low.....
