How do you replace the alternator on a 1995 Chevy Astro?
On all the Astro/Safari vans I've seen, the alternator is located on the passenger side of the engine.
Recommended tools:
- 8mm box-end wrench or socket (not all will need)
- 10mm DEEP box-end wrench or socket
- 13mm box-end wrench or socket
- 14mm DEEP box-end wrench or socket
- 15mm box-end wrench or socket
- 3-inch socket extension
- 3/8-inch-drive ratchet
- steel "butter knife" or suitable substitute
- teflon tape or other "thread sealer"
If you elect to use a 1/4-inch-drive ratchet in lieu of the 3/8-inch-drive ratchet, limit its use to 10mm-or-smaller sockets: the threaded fasteners in this application having larger heads require greater torque than can be safely and reliably applied using 1/4-inch-drive hardware.
Read this entire procedure first, then decide whether this is a project for you to attempt.
There are significant minor differences to the specific procedures involved, to wit:
(1) Always observe all applicable safety procedures.
(2) Disconnect the cable from the positive (+) battery terminal. For some vans, you will need an 8mm socket or wrench; for others, you will need a 10mm socket or wrench.
(3) The power steering reservoir is in the way on vans having the Z-code engine: leaving the hoses attached and avoiding tipping of the reservoir, remove and save the screws that hold the reservoir to the cowl; then bend the hoses and rest the reservoir on the driver's side of the radiator shroud.
The air filter box is in the way on vans having the W-code engine. Open the clamps that seal the box, remove the filter: the nuts and bolts holding the airbox in place are visible. Remove the airbox, saving the hardware.
(4) The ductwork supplying the engine with fresh air is in the way. Usually, these plastic pieces just click together, but there may be one or more clamps, nuts and/or bolts, or screws holding some of it in place. The offending portion consists of the following pieces:
(a) the lower part that turns the air about 90-degrees, so that the air flows upwards,
(b) the upright section that channels the air upwards (it looks like an accordion's bellows on the Z-code engine),
(c) the upper ductwork connecting the upright section with the air filter housing.
I have heard that some ductwork installations are secured using #2 Phillips threaded fasteners (screws); if yours is such an application, you will also need a #2 Phillips screwdriver.
(5) Remove serpentine belt. The ratcheting tool that looks like a long, flat handle -- it came with the vehicle as part of the lug wrench kit -- has an opening that fits the pulley on the tensioner. Using the tool, loosen the tensioner with one hand and slip the belt off using the other hand.
At this point, whether you need to remove the fan from the front of the engine should be obvious. If you must, be aware that so doing without removing the shroud really isn't going to give you much room (about 1/2 an inch, maybe an inch).
If you need more than that, the shroud has to come off so that you can remove the fan. Although at 13.5 inches (34.3mm) circumference and 14.5 inches (37.9mm) circumference respectively, my forearms and upper arms are rather small, I think that needing to remove the fan to have enough room is a highly unlikely condition.
(6) Remove the engine oil dipstick bracket from the stud holding the alternator to the bracket. The nut securing the dipstick bracket is probably a 10mm. Remove the dipstick bracket from the stud. Be aware the dipstick tube could slide from the engine.
(7) The alternator bracket should be loosened from the front of the engine. Remove the bolts (it should be a trio of 14mm bolts) and save them. This allows the bracket, tensioner and alternator to be tilted away from the engine. At least one bolt may be wet with engine coolant; seal the threads of any such bolt before reinstalling it.
(8) Use an appropriate tool to unclip the plug from the alternator (I used a "butter knife), and remove the red wire from the lug at the back of the alternator. The nut securing the red wire to the alternator is probably a 10mm; the stud in the alternator is probably a 15mm (menitoned just in case the new one needs snugging).
(9) Remove the bolt from the rear of the old alternator holding it to the bracket (either a 13mm or a 14mm); then remove the stud holding the old alternator to the bracket (either a 13mm or a 14mm); then remove the "hinge" bolt holding the old alternator to the bracket (either a 13mm or a 14mm bolt screwed into a 15mm nut).
Installation of the new unit is done by reversing the steps of disassembly.
SAFETY NOTES: Be aware that there can exist pinch hazards during this procedure. Also be aware of the possible hazard of falling tools and/or debris.
Helpful hint: if possible, have someone else hold the bracket/alternator/tensioner assembly in-place while you start the lower 14mm bolt by hand from underneath the passenger side. This makes installing the upper bolts much easier.
Start ALL the bolts before tightening any of them. Generally, it goes pretty quickly if you begin with the "all bolts finger-tight, then all bolts hand (wrench/socket) tight, then all bolts torqued" method.
NOTE: Conspicuously dexterous people may not have to remove the alternator bracket, but in my opinion, the procedure is much easier if this is done. You should never have to remove the doghouse (engine cover inside the van) to replace the alternator. If a mechanic told you he/she did it that way, you should be going to a different mechanic.
On a 2000 Grand Am how do you replace the plastic clips that hold the regulator to the window?
You can't! I know it sucks but you have to replace the entire regulator assembly. Actually, it depends on which plastic clips you're trying to replace. True that the plastic slides are only available as part of the regulator, but the plastic glass channels are available separately from various sources, including Advance Auto's "Help!" section. The adhesive to attach is another matter, however. GM sells individual use vials at incredible prices that typically aren't in stock and are available only in box quantities, if special ordered. Check glass/windshield replacement stores, or NAPA sells a eurothane adhesive that has so far worked for me. Not exactly inexpensive, but doable. Be sure to buy the primer that goes with it, strength only a fraction without it!
How do you check to see if engine is firing?
You can do of a dew different ways by sound or sight start the van and remove the plug wires one by one and listen for changes in the sound of the motor or you can remove the plugs from the block and keep the wire connected to see if you have spark that way..just use insulated plyers when doing this to avoid shock

How do you open rear door with broken handle of astro van?
You have to take the inside handle apart to activate the latch manually. If you can't do it from the handle area you have to remove the inside door panel.
How do you adjust timing on an 88 astro?
First you need to have a timing light, once you have attained one (if you didn't already have one) you have to hook up the alligator clips on the respective battery terminals and the inductive lead on the #1 cylinder spark plug wire. Next you need to loosen (not remove) the distributor hold down clamp bolt. With engine running, you need to watch the timing marks on the vibration dampener attached to the crankshaft pulley and adjust (turn) the distributor clockwise or counter clockwise until the appropriate mark (see the emissions sticker by hood latch for desired timing setting) lines up with the pointer on front of motor, being VERY careful not to let and wires for timing light or any part of you get too close to cooling fan! When the lines match, tighten clamp and you should be fine. It may take two people (one to watch the marks and one to turn the distributor) to adjust.
its a very good idea
Where can order new keys for a 1994 astrovan?
Check with your local GM/Chevy dealer. This could be a dealer only item, especially if there is a special 'chip' inside the key for identification and anti-theft purposes.
How do you fix a code 44 on a 1994 Astro van with the Vortec engine?
Code 44 indicates a lean mixture at the oxygen sensor and it could be a variety of things from a vacuum leak, a bad fuel regulator, or a bad fuel pump. Also those engines were known for bad distributor shafts. It is best to take it to a mechanic.
Where is the horn located on a 2004 Chevy Astro van?
look up near the raditor or batt. area i know ford loves to play hid the horn on a lot of the cars.
What would cause a whistling from the heater?
My car was making a noise, although I would describe it as more of a "hissing" sound, from the heater/AC control panel. It turns out to be the heater control assembly that was bad. I was told another possibility when you hear that noise is the water control valve.
sounds like a system with vacuum controls( found in higher price/luxury vehicles ) for changing settings...def.,floor/heat,vent,etc. a cracked hose-or a hose that has popped off of the 'nipple' it fits on. does it change when you change 'mode-heat,def.,etc? also, there is a ' manifold ' where all the air tubes are joined and feed vacuum to move doors,etc. for heat-def. etc... somewhere under dash-passenger side-or near center that can leak at main vacuum feed. it looks like an cow's udder-clear plastic air lines connect there and go to respective controls for heat, def.,vent,etc. move the hoses a bit- with car runnuing-listen for change in volume of 'hissing'. of course-this problem could be at the control valve in the dash where you make the desired changes for heat,def., etc. the control valve is expensive- i have bought/sold vehicles for 40 years. i am a supporter of 'junk yards '...er,auto recycling businesses. they will pull the part-now you need to find an installer- this is a bit complicated,based on vehicle and location of hissing problem.finally...do all of the options for heat,def., etc. operate correctly-try runniong the system "thru the paces" a few times and listem for changes,location-as i said before-good luck...
How do you replace a lower radiator hose on a 1998 Chevy Astro?
The 1998 Chevy Astro lower radiator hose is held in place with a clamp. Turn the clamp screw to the left. The clamp will become loose and the hose can be removed.
How do you change the rear speakers in a Lincoln mark 8?
To remove the speaker grilles in the rear of a Mark VIII gently pry up on the lower forward portion of the speaker grille. Do not forceor pull on the grille, just pull it slightly out from the interior panel and then move your finger under the grille along the lower portion and up the back side. This SHOULD dislodge the clips that hold the grille in place. Now pull down very carefully on the entire grille assembly and it should be free of the interior panel. Now there are four TROX screws holding the woofer and two for the tweeter....
How do you install an ignition switch on a 1994 Chevy Astro Van?
You will need to remove the steering wheel to gain access to a screw which holds the cylinder in the steering colum. But if there is an air bag you will need to disconnect the battery then remove the air bag then you'll need to remove the pressure plate then the signal harness. After doing all that you'll see a screww at 3 o'clock which is either a torx screw or a hex head screw. aftyer removing the screw then pull on the cylinder and it'll come out in your hand then insert new one. I hope this helped
need to know how to remove the steering colum?
Where can i find a Sliding mechanism for sliding van door?
A sliding mechanism to repair a sliding van door can be purchased from a dealer for the vehicle in question. It is sometimes possible to find this part at an auto salvage yard.
Check the ECM electronic control module under the distributor cap. if its bad it wont start or will start and run bad and die
How do you disable the automatic headlights on a 2001 Canadian Chevy Astro?
On my 2000 Astro there is a small button just below and to the left of the headlight switch. Push that button four times in a row and you will hear a chime and the automatice headlights will be disabled. Tricky, eh?
Replace the small looking shocks. That's what holds the door up.
This could be the starter, or the ignition switch.
It sounds a lot like you have a brake problem. You need to get it checked out before any more serious damage is done, and it costs you a fortune.
How do you turn off air bag light on 95 dodge ram 1500 pickup?
If the light is on the airbag system is disabled, and there's a problem. You can't just shut it off. Hook up a scan tool and retrieve the fault code and fix it right. or the airbags will not deploy if you're in an accident.
Prolog:
I'm pretty sure we all know to fix the problem, but most of us just left the airbag lock unplugged or the seat unplugged when we turned the key on. I too am searching for a cure. I know Nissan titan's you can key on key off 3 times to reset.
