Chevy Astro

you dont only a certified repair shop can

the distributer cap is located in the back of the engine and to get to is is relatively painless but you have to remove the engine cover on the inside of the vehicle which is under the dash in the middle of the vehicle which there is 2 big standard screws holding it to the firewall and 2 clamps holding the back side to the floor towards the seat. once you gain access to the engine compartment from the inside of the vehicle you will see the distributor cap right there looking at you. it is usually held on to the distributor by 2 small Phillips screws and will tell you first hand if the cap has not been changed in a while you might want to use a nut driver to break them loose and re-install in just reverse.

Sound is the periodic compression and rarefaction of a medium, this change being produced by a vibrating object or other medium mass. If something vibrates, it starts vibrating the air around at the same speed. These vibrations are transmitted through the medium and sound is produced. Basically, something shakes the air (or water or whatever) back and forth. The shaking gets passed on to all of the air (or whatever) around it, which causes times of higher and lower pressure with a regular rhythm.

2WD Astro Van�s have load problems with their rear differentials. The �Grinding Noise� is a bearing of some type. Axle bearings can be replaced with a moderate to advanced skill set. However any other bearing, pinion, or carrier, require professional tools and a shop press; such an operation is beyond the normal means of almost any auto shop and require a shop with a good machinist or straight gear specialist.

Bearings that go un-repaired for too long result in misalignment of the pinion � carrier set and warping of the axles. None of these operations are easy, or cheap.

I am finding that astro vans are very likely to bend the rear end housing. I am fixing mine for the second time now. The axle housing bends and then puts the carier bearings in a bind. also check the outer ends of the axle shafts for bearing wear. Replace the shafts if you see any pitting or galling. Good luck.

Astro Camp is way up high in the mountains.

well it depends on which parts!

you need to be a little bit more specific here..

How much does it fluctuate? It is normal for oil pressure to rise maybe 20 pounds when you rev the engine. My SUV goes from 40 pounds to 60 pounds and then back down to 40 at idle. this is normal. The faster the engine rotates the more oil pressure is needed to keep everything lubricated properly.

it could be a exhaust leak.

On my Astro, the firing order is located on the distributor cap- Where each plug wire goes into the cap, there is a number on the cap-find#1 go clockwise for the next number etc. That's your firing order

It is on the lift support shocks on the rear window hatch. Each side has one.

What does IAT stand for

I also want to know how it comes free from the engine after all bolts are removed? If anyone knows how, please share your experience or knowledge. I tried to pound it free; also used a sharp flat bar with heavy hammer to split it free from the engine, but it does NOT begin to break apart. thanks so much for anyone's help. Please send info' to: art.zimmer@gmail.com

The prefix astro means the Greek word 'star'.

it is under the glove box on the passenger side. it literally takes 5 minutes to change it. the part cost is about $15. 2 screws and it drops right out.

I think I had the same problem on my 2000 and decided to just take off the lower radiator hose to drain it.

The Freon probably needs to be recharged. Any repair shop should be able to do this. They should also test the system for leaks to see why the Freon leaked out to begin with.

Hey Dude: You can turn your dome light off in your van by turning your headlight switch (or dimmer switch ) all the way to the right. Left turns on your dome light, so go the opposite all the way till it clicks. It will now stay off when your door opens. .

Check the following................

1. Power and ground to the blower motor.

2. Blower resister.

3. Blower switch.

Jack up vehicle loosen the 10 differential bolts using a screwdriver pry off pressed steel cove allow oil to drain , clean metal magnet off located inside diff cover, clean both mating sides to cover and differential housing, replace with a gasket which you buy at the local parts dealer with 80/90 weight gear oil, put gasket on torqued to specified tightness, remove check fill plug passenger side differential fill to the quantity specs and that it (note use a wheel blocking system before performing this task 1/2 inch socket required to take differential bolts off , gasket costs $6.00 same as rtv sealer but way easier and less messy to use.

You either have a cracked head gasket or a cracked head or a cracked block YOU MAY HAVE A BLOWN HEAD GASKET OR A CRACK EITHER ON THE ENGINE BLOCK OR CILYNDER HEAD. YOUR OIL HAS CHANGE TO A MILKY WHITE SUBSTANCE RIGHT? IS THE CAR SMOKING? Yes it smokes like a freight train.I RECENTLY REBUILT IT AND PUT AN ALUMINUM EDELBROCK INTAKE AND CARBURETOR ON IT. I HAD THE BLOCK CLEANED AND BORED 40 OVER AND ALSO HAD THE HEADS SHAVED.COULD IT BE THE INTAKE ? IT SEEMS TO ME THAT AS FAST AS IT GOES INTO THE OIL PAN IF IT WAS A PROBLEM WITH THE BLOCK OR HEADS THE SHOP WOULD HAVE SEEN IT. THANKS FOR ANY HELP YOU CAN GIVE. TRY CHECKING THE MOST COMMON CAUSE WHICH IS THE HEAD GASKET. TRY THIS TEST. IF IS A V6TYPE ENGINE TAKE OUT MIDDLE SPARK PLUG ON 1 SIDE ONLY, AND HAVE SOMEONE CRANK THE ENGINE.(JUST CRANK IT A FEW TIMES OR START IT FOR A SECOND ONLY)YOU SHOULD BE ABLE TO SEE THE "SMOKE" COME OUT OF THE SPARK PLUGS HOLE. IF NO SMOKE, GO TO THE OTHER SIDE AND TRY THE SAME TEST . ONCE YOU FOUND THE SIDE THAT IS HAVING THE PROBLEM ALL YOU NEED TO DO IS BEGIN LOOKING FOR CAUSES.(''IF YOU GOT SMOKE ON '''BOTH''' SIDES THEN THE PROBLEM MAY NOT BE THE HEAD GASKET ,VERY RARELY BOTH SIDES GO BAD AT THE SAME TIME'') SINCE YOU SUSPECT THE INTAKE ,HAVE A LOOK AND CHECK IF IS SITTING PROPERLY IN PLACE AND THE GASKET IS IN PLACE.BUT NORMALLY 99% OF THE TIME THE HEAD GASKET IS TO BLAME. NOTE.COOLANT USUALLY BURNS OUT IN THE COMBUSTION CHAMBER ,BUT SINCE YOU HAVE FOUND IT IN YOUR OIL PAN YOUR PROBLEM MAY BE A LITTLE DIFFRENT/COMPLICATED.YOUR PISTON RINGS ARE ALLOWING IT TO GO DOWN IN TO THE OIL PAN WHICH IS SOMETHING THAT HAS TO BE ADDRESSED AS WELL.
