You will need to remove the power steering pump belt in your 1997 Chevrolet Express. Remove the power steering pump hose. Remove the power steering pump retaining bolts. Reverse the process to install the new power steering pump.

Perhaps plug wires have become porous and need replacement

in the fuel tank, connected to the fuel pump. You must drop the tank in order to service it.

how do i remove an antenna to a 1998 chevy express 1500 van

i had the same problem with my 3500 express and it was the fuel pump not getting 60 psi. i olny had 45 pounds and it was hard to start cold

Drain the water from your 2003 Chevy Express 2500 cooling system. Remove the belt from the water pump. Remove the water return hose. Remove the water pump retaining bolts. Reverse the process to install the new water pump.

It has no drain plug on the A/T.

i need a diagram of how to inslall the belt on my truck

Many vehicles have been engineered to have the fan motor run at least in low speed as long as the key is on. If the fan is staying on while the key is off, check the key switch to make certain that it is turning off the accessory circuit.

A relay should not get much hotter than the air around it. I clean carpet with my 1998 Chevy Express van and I noticed the same issue of the relay getting extra hot. This was because my van is stationary and the carpet cleaning machine runs from a drive axle going to the van's engine. Not only is there a rather air tight cover over the fuse compartment under the hood, but the engines heat circulating around this area doesn't help much.
Even with the issue of engine heat and a somewhat air tight fuse compartment, there shouldn't be excessive heating of the relay. Here are two reasons for the excess heat. First, if the fuel pump is demanding more current flow from the battery it can cause the relay to get hot. More resistance in the pump due to a poor connection, or possibly there is a physical resistance associated with the pump- a worn or seized bearing, a clogged filter etc. These are reasons a relay could get hot. Secondly, any poor connection- the wiring harness under the vehicle which is going to the pump has a connector that is notorious for heating and cooling/expanding and contracting, which will drive a person nuts. It took me weeks to figure out that this was the reason my van died randomly. I had gone so far as to remove the fuel pump and put a jumper between pins 87 and 30. At least if you do this you will be able to hear the fuel pump running, or not, without the noise of the vehicles engine drowning it out. It was at this point that I realized that this poor connection at the wiring harness was causing the increased resistance at the relay, and hence it getting hotter.
While we're on the subject of fuel pump relays, note too that it is the vehicles main computer that turns on this relay. If you've ever accidentally shorted out the computer's + to this relay to ground, you're fuse to the ecm ( electronic control module [computer]) might or might not blow. Either way there is a good chance that the computer will stop sending this 'switching' voltage to the relay. The computer is in charge of this relay primarily for safety reasons. In case of an accident the relay removes power to the fuel pump. A good thing this is surely, but buying a whole new computer in the event of this circuit failing can be cost prohibitive to many of us poor drivers. BTW, used computers at a pick and pull junk yard are pennies on the dollar compared to the dealership. I paid a whopping $27 for my 1998 Chevy express computer. The junk yard will give you a list of compatible models that have the same computer in them. I got mine out of a 2500 truck. No tools needed to do the job, but always unhook the battery before removal of a computer. These Chevy's have a tendency to die at stop lights after a computer swap, until it 'relearns' the idle setting. This is normal.
If you are short on cash, or in a jam and need to get your vehicle home, either bypass the relay with a jumper, or in the case of the computer not activating the relay to the fuel pump, you can simply run a 12+ wire to terminal 30 ( or whichever wire is + to the pump). If you take a wire from another 12volt+ circuit which is switched with the key AND remains ON during RUN ( like the 12+ coil[ be careful not to short out the ignition module]) then when you turn off the key the pump will also turn off.
For safety reasons always use a test light to find the proper wire, find a good accurate wiring diagram, and replace the computer as soon as possible.

I found out what the problem was - the idle air controller

take the bolts out then undo the wires then put the new one in.

1993 sc 400 fuel injection pump location?

how do you know if it bad ?

You will have to pull up the seat fabric on the backrest enough that it exposes the area where the armrest is mounted. Inside you will see the pole from the armrest coming into the seat, held in place with a sort of horseshoe shaped clip. The clip also has a rubber band holding the two open ends tight together. Using needle-nose pliers, remove the rubber band. Then take screwdriver and push the clip backwards out of it's groove. The armrest will then come right out.

For re-installation: before placing the armrest back on, attach the clip and the rubber band and re-seat the fabric properly. Once the seat is ready, simply shove the armrest through the hole and you will hear a "click" meaning the clip has grabbed the armrest.

This sounds like a hydraulic valve lifter that is dirty, sticking and is not getting enough oil to lubricate the lifter. After the engine warms up and the oil pressure is stable, the lifter begins to get enough oil and quiets down. Try changing your oil and use a lighter weight oil like 10/W/30. After 2500 miles return to your former vescosity oil.

I have 04 express V6 4.3 and once i got 595 miles on a tank, 80% highway driving, in the end i actually run out of gas

On my 2004 3500 Savana, it is under the hood, under and just behind the blower fan. It is not a 'tube' per say, but rather a plastic black square formed tube, that snakes a bit downward, with a rubber flap on it's downward end. That flap faces the passenger's wheel, and has a weighted portion on it that keeps the flap closed. I'm having to clean mine out right now, and am finding maple seeds and mud (possibly wet dust) blocking the water from escaping.

The horn relay and horn fuse in that van should be on the driver's side the hood, closest to the right side in a black square container. This is near the windshield washer fill area - ya smart, and usually has a water splash guard there slightly over it.

Autozone told me and showed me a picture of the temp sensor on my 2007. It is screwed into the head just above the plugs. Of course we could not see it from looking under the hood. I'm gonna bring mine in and let the shop fix it.

Remove the glove box liner and there you will find it!

My relay has 5 pins, but the replacements have 6, have I found the right relay

To change the engine timing you have to reprogram the ECM with a flash programmer from aftermarket chip and tuner companies like SCT Hypertech and Diablosport

There is not drain plug, you need to remove lower rad hose.

I discovered this situation while fiddling with the selector knobs in the dash. I still haven't fixed it completely. I removed the air position selector knob, the rear defrost button in the center and a little diode in the center that lights up when the rear defrost is on. Somehow I haven't got everything aligned and when you put everything back and snap the knob in to seat it, it's somehow forcing the system into defrost mode, which I assume is a fail-safe mode. I have removed the button from the center and now it seats and everything operates fine. I don't have the actual answer, but I know my '95 Stratus started doing this. I took it to the dealer and they told me that a solenoid need changed. It was only $35 for the part, but they said Chrysler had made a change that would require the entire computer to need changed IF the solenoid was changed. I told them to put it back together. Later, I remembered that it had happened previously, but started working after the battery had gone dead. Therefore, I made the deduction that by disconnecting the battery, I could reset the computer and make it work. The process worked and I have had to do it 3 or 4 more times. It always fixes the problem! Much cheaper than the $800 dollar computer they wanted to sell me. All you need to do is remove the fuse from the interior fues box, turn the car to ON (no need to start), turn the car off, replace the fuse, and all should be fixed. This is for if all speeds work, but it only comes from the defrost vents. If ONLY high works, then it is the blower motor resistor, which is a cheap part and can be found under the passenger side dash. Also an easy fix.
