The can from Wal Mart has a pressure gauge on it and a chart telling u how much pressure to use in what kind of air temperature. The blue is within acceptable range the yellow is below and the red is overcharged which can damage your system. If it is still not working u have other problems

The 91 Vandura G2500 Instrument Panel Cluster Relay is located on the dashboard.

It is under the rear of the van on the passenger side against the frame, it is held in place by a bracket with one bolt, loosen the bolt, get you some rags because the gas will leak a little, don't worry it's normal, loosen the bolts on both ends of the filter let gas drain out till it stops, then continue taking the lines off, pay attention wich way the flow goes, then replace the same way you took it off.

The issue we have with our 1990 GMC Vandura 2500 is that it won't shift into third. I had talked to one of my coworkers at the Tires Plus in Minot and he said that part of the tranny got clogged or something along those lines. Also according to him, it was a problem that the 700R4 transmissions were notorious for.

,ok that big thing in between the driver seat and passenger is the engine cover,there will be 2 bolts at the bottom, left and right under the carpet,so remove those then about where your knee would hit it theres a latch on the left and right undo both latch's and lift up and out,you might have to rotate or lay down the chairs to get it out of the van...good luck

to the right of the brake booster

Your best bet is to just go to the library, and get the book there i have a 1990 and it was a pain. Had to remove the shard,fan,belt. Not alot of room to work with so when i was ready to rebolt it back up i used a steel rod to hold one side in place to bolt it back together. and for the shard that covers the fan i cut mine in half and put 2 bolts to reconnect it reason being is if i have to take it off again wont be a pain to get out. Works great

because your linkage is not correctly adjusted.

both are 1998 gmc 3500 with a fiber glass box on back on 1 an also have just a cargo van too

Vacuum hoses are used to operate power brake boosters, E.G.R. valves, P.C.V. valves, and even heater/air conditioning controls just to name a few. It is very important to have these hoses hooked up correctly. There should be a vehicle emission control information sticker under the hood or on the radiator cover with a vacuum hose diagram.

Pull the valance off the bottom of the wind shield.

I have a 1995 GMC Suburban and started having similar experience with the difference of when I press my brake pedal my dashboard lights come on and my left turn signal stays on when my headlights are on. From conversations with mechanics it may be one of several things. You may want to gently "jiggle" your turn signal handle either while the left signal is on or before turning it on to see if that changes anything. You may want to look at other lights to see if any others are on or off while the turn signal is on. The brakes are wired through the turn signal handle and may effect how the signal is working and this may help narrow down the problem. Make sure you check your bulbs and finally you may have a ground wire that is not grounded well.

I have a Frontier Campervan conversion on this vehicle type and can answer for that.

1) Turn on the propane at the tank.

2) Take the front panel off the furnace by pulling the top straight out then lifting.

3) Turn the propane on at the furnace by rotating the red knob 1/2 turn to the ON position.

4) Replace the furnace cover.

5) The wall thermostat has an ON/OFF switch on the bottom. Click it to the ON (right) position.

6) Adjust the temperature using the top slider on the thermostat.

The thermostat should first start the blower then, after a few seconds, start the igniter. I can easily hear the igniter 'tick' as it sparks.

That's all there should be to it.

remove the arm rest cover , you can see the bolt

follow the upper rad hose from the radiator to the engine, it should be in the part that the upper hose connects to and bolted to the engine (if memory serves), this based on a g2500 with a 5.7

Is the "Security light" on the dash active when it wont start?

5 liter is the engine size. In non-metric its 305cid

On the back of the motor next to the transmition.

Starcraft supplied a complete wire diagram for what they installed..I have one for my '88..

What about it?

My thought is that 8 lugs indicate that you have 3/4 ton or possibly 1 ton wheels and axles while 5 lugs indicates that the wheels and axles are 1/2 ton variety.
