Electrical / Lighting Systems Malfunction Happens sometimes Not applicable

Q:  Have a 1997 Ford Aerostar with the 3.2 engine. The "check engine" light was on about a year ago. I replaced the O2 sensor before the converter and it seemed to solve the problem. Recently, the light comes on for a while and then goes off. The parts store plugged a code reader into the van and said that the gas cap was bad -- they said the seal was bad and letting air into the fuel system, causing some "evaporator valve" to stick. Put on a new gas cap and still have the light coming on for a while and then going out. Any ideas?


A:  1997 Aerostar only came with a 3.0 or a 4.0 engine--symtoms soound like a PFE sensor--they are bad to collect moisture--I would take to a Ford Dealer if it were mine--they are best equiped to handle the problem --you can spend a fortune guessing and they can fix it right the first time.

Drive Train / Driveline Malfunction When driving When warm 

Q:  Greetings :)
My Van has 225,000, the engine and tranny was replaced but it has a lot of miles since then.
It is the rear wheel drive ext, if this makes any difference I LOVE MY VAN.
Anyway I am lucky a transmission shop checked out my tranny and found all seals are in good shape.Where I am losing the fluid is out of a vent. The transmission fluid oozes out when it goes up hills, making it look like I have a BQ tailgate party.
It shifts fine otherwise aslong as I continue to check the fluid.
What has happened inside the casing??
and as long as I have you interested in my story......heheheh I have the abs,emergency lites on. It continues to stop fine and the emergency is not on. Howcome ??
Thanks alot Sharon


A:  If the abs light is on, the computer has "seen" something in the system it did not like. Also the computer could be wrong. Disconnect the negative battery cable for at least one minute and see if the code returns. The transmission is confusing. Assuming that the fluid level is correct, I can think of no good reason for the fluid to come out of the air vent tube. Ed

Q:  I purchased a new CD player to install in my 95 Ford Aerostar Van 4.0 liter. Can you tell me which color of the Aerostar radio wire harness is for: a. power b. ground c. L and R front speakers d. L and R rear speakers Thanks, Victor


A:  You could probably find that info in your van's Chilton manual (most libraries have these in their reference section if they have them at all), but if you'd rather do it yourself, it's really pretty simple. Go to http://www.crutchfield.com/S-ChN96k5L6My/tech/kb31.html and follow the directions. Use a good multitester (I got mine for $11 at AutoZone) and have a secure chassis ground for the negative probe when you're working (I usually fasten it down with electrical tape). There's a link at the end for the "battery pop test" to find which speaker wires go to which speaker. All you need for that is a AA battery (don't do this test until AFTER you've separated out your "hot" wires). Good luck!

Engine Other When driving When cold

Q:  Rough idle when cold, sometimes when warm too. Misses on grades, but not always. Replaced fule lilter already.


A:  Check under hood, while dark, with engine running, for any sparks or flashes coming from ignition system(plugs,wires,cap/rotor,coil). If you see any errant lightning you should change all of the above parts except coil.

If the problem has been going on for awhile and it is in the ignition you should check the coil eletrode for wear and replace if it looks real bad. If the problem is not in the ignition, check vaccum lines for leaks or obvious signs of deteroration, replace if they are bad.

Also check around throttle body to intake manfold for leaks, could be a bad gasket. you can chek for leaks with some water in a squirt bottle or garden hose, if you have a leak the water will be sucked into the vaccum system and you will hear it. If you do have a vaccum leak though you probably would have noticed the vehicle running to hot, although it may not overheat. If these things fail to find or fix the problem you can try running the self diagnostic tests found at
http:dalidesign.com/hbook/eectest.html but keep in mind that a simple problem often makes the computer think that a complicated and costly part is causing a problem. Hope this is helpful to you.

Q:  A couple of weeks ago I was driving and lost acceleration. There was a knocking sound and the van started shaking, running awful. We put supreme gas in the tank after putting new plugs and fuel filter in it. The tank was at half when we put the supreme in. It ran good until it got down to half a tank the we put regular gas in and it started knocking again after 2 weeks of running good. Mechanics have said that it sounds like bad gas and put some straight alcohol in the tank to get rid of the bad gas but the engine is still knocking.


A:  You need "Isopropal Alcohol" (not the "Methal Hydrate" type). Also, if possible, drain the gas tank completely and start with a fresh tank of gas. The engine is not enjoying the other stuff. Ed

Q:  4.0 litre engine A4LD auto trans. Flywheel replaced in November. Transmission went in January. The flywheel broke again in June and now again. It seems to curl up around the center hole and then shatter. The mechanic where it is taken (a transmison shop) thinks he may have found why this is happening and it's something he never would have thought of. It appears the fan blade is also loose and ready to break and go through the radiator. He thinks that the vibration from the fan may have been severe enough to also cause the flywheel to vibrate and eventually to crack. Does this sound possible? Is there any flywheel breakage common in this vehicle and if so, what would you suggest?

Q:  I was just recently traveling in my aerostar, when all of a sudden there was a loud sound like a explosion . We we're going 65 mph. Looked at gauges all off and dash lights were on. Assumed that motor had blown. But instaed the rear end had locked up and broke the spider gears, ring gear and pinion. I tore it apart and replaced the gears with used and all new bearings. After doing so it sounds great no noises at all driving or other wise form park to drive or reverse, sounds good. But after having it on jack stands running it a 65 mph. for 60 miles the rear end housing was pretty hot, you could touch it but couldn't leave your hand on it.

Q:  Hello, thought I would drop a line.

This is about oil pressure. When I start there is a ticking sound, and the sound comes and goes.

When I use 5w30 it seems to help but the ticking is still there.

A friend of mine said he thought it might be the oil pump. My oil gauge comes up and stays in the same place all the time.

This Van has 134,000 miles on it and it runs good. If it is the oil pump, do I need to lift the engine to take oil pan off or is it fairly easy?

Is there a way to check this, or do you recommend looking in another direction?


A:  Oil pressure should be at about 1/2 of the gauge while driving. If the thermostat is bad in this engine, it causes cool running and varnish build up also. Ed

Have your guage and oil pressure sending unit checked to make sure you are getting a correct reading.

Try this...on a cool morning, pop the hood, take the oil cap off, crank the car, let it run for a couple of minutes, then look inside the valve cover at the rocker arms.

Are they fairly coated with oil?If so, good.

If at any time you hear a ticking or knocking sound DO NOT DRIVE THE CAR ANY MORE. You need an oil pump or the pick-up cleaned.

Q:  Chugging at idle, dies when put into gear and brake is released.Mass airflow sensor has just been replaced.


A:  Why was the mass airflow sensor replaced ? This is an air temperature sensing device and would not be in the line of things to cause your problem . Look for an injector that is staying open , vacuum line that is leaking , a gasket anywhere in the air inlet system ( from where the aircleaner connects to the engine block itself ) and any obstruction in the air inlet system . Heard of one person who had a chicken stuck in their air inlet . That engine ran just fine after the chickenectomy was performed .
An engine that dies as you say yours does is lacking one of two things , air , or fuel . To much fuel can cause the chugging . Look for black smoke . Oil causes blue smoke . A throttle linkage problem could cause your problem . Not enough air , or to much air by way of a vacuum leak could also be at fault . By the way , a computer check would not hurt , and may save a bunch of time . Any error codes can be extracted from the computer . If the diagnostic shop will not tell you what the codes are and what they mean , complain to the BBB , shop owner , or , best of all , your states' Attorney General . Nobody likes to say why to the state AG . Helping consumers is part of what the state AG is there for .

I have replaced the master cylinder, front calipers, front hoses, rear wheel cylinders, rear brakes shoes, rear break drums. I have cleaned all parts and the breakes work fine as long as you don't have to use heavy breaking.


A:  It really is frustrating when " shot gun " repair doesn't work . Your problem was in the rear end , the master cylinder would immediately be ruled out , as would the front calipers and the other stuff you mentioned . It really is a good idea to learn how the various systems in your car operate so that you make the best decision possible .
"Shot gun " repair is always costly and is only marginally successful . Check the springs in your rear brakes . If these are weak then they cannot overcome the residual force left in the cylinders and pull the brake shoes away from the drums . Also make sure that the emergency brake is connected properly .

I have removed the plug wire to the missing cylinder and at idle there's no change, but under acceleration you can now hear and feel it. The cylinder seems to work under load or higher Rpm's. I have also removed the valve cover and found nothing wrong. There is a tapping coming from the engine which gets fairly quite after it heats up. The engine does use a little antifreeze and there isn't any leaks. The compression is all between 145-155psi except for the dead cylinder at about 20-30psi.


A:  I know this this sounds like a backyard mechanic trick, but try it. Take a dollar bill to the tail pipe while it is running. If the exhaust is fairly sound see if the dollar gets sucked to the pipe a little, not constant. If it does you have a burned valve and will need to have the heads either replaced or rebuilt. If not check the valves under the valve cover and check if one looks a little lower than the other on the "bad" cylinder. You have two for each. This is called a stuck valve and you will still have to have the heads serviced.

Q:  I have an '89 Ford Aerostar with a 3.0 liter engine. I am trying to set the ignition timing; however, I can't locate the "spigot connection" to disconnect it. I've timed a lot of cars, but this has baffled me. None of the connections on the distributor look like they can be disconnected without completely disconnecting the distributor.


A:  look under the hood near the eec diag connector

Drive Train / Driveline Malfunction When starting Always

Q:  I do not move sometimes when I put van in drive. It will work if shifted to reverse and drive several times but leaves me sitting about 1/2 minutes at times.

Once the van has started to move normally it usually is ok til it is killed and restarted or put in park.

It also stops working if overdrive is used. Total breakdown a few months back and new piece was put on the trans.

The part just before the trans that tells it when to go?? and they didn't get it fixed til the third trip by tow truck.

They said that the gears that mesh with the trans. were the problem.


A:  sound like it needs reworking again by someone different this time

I have just had a similar problem with a transmission. When work is done on the inside of a tranny, little metal flakes clog the governor and the car needs to be run in reverse for a distance, 50 yards or so to free it up. Then if it continues, it should be flushed and serviced and with alot of miles a good quality additive like R&K is good to add. Also put a few magnets on the bottom of the pan to try and pull the flakes to the bottom before flushing.

Heating / Cooling System Malfunction When driving When warm 

Q:  Is there a fan motor available with a higher rpm than the stock fan motor? The air is cool, but the fan motor lacks the power to move it to the back of the van. Any suggestions would be appreciated.


A:  I would first inspect the ducting. Especially on the 'air in' side. Leaves, debris, etc. Keep in mind these can restrict flow anywhere along the path. The motor could aslo be operating at less than peak efficiency... IE- worn, dirty / broken / distorted squirrel cage (or fan blades)

Ignition System Won't Start When starting When warm 

Q:  I have a 1989 Aerostar.The battery goes dead if the cable is left on the battery cable more than a couple of hours. We have checked the alternator and it seems to be good. What can cause this to happen. The battery has also been check for good. Wendy @ dwdj2001@bellsouth.net


A:  You probably have a parasitic draw from another component in the vehicle. This could be a number of things and a complete diagnosis is difficult to manage online. However, a simple test to point you to the system affected will be to disconnect the negative cable on the battery. Then take a multimeter with a milliamp function and place the black lead on the cable.Take the red lead and place it on the negative post. Go to the fuse box and individually pull out fuses one at a time. Observe the meter and if any fuse gives a reading of higher than .05 the fault is in that circuit. Also before doing this have you checked the starter for excessive current draw? If you have further questions contact me and I will try to help you.

Q:  My Ford 1988 Areostar 3.0L with overdrive surges when going up hills. I replaced plug wires and all, did a complete tune up and replaced the fuel pump. Also checked all fluids and all. But I still can't find were this is coming from. If I put the transmission down into drive, out of the overdrive, it won't surge. Can you tell me what is going on?


A:  maybe the transmission is going out could also possible be a throttle position sensor which would give you a jerking like a spark plug,very common on the 3.0 engine

Chassis / Suspension & Steering Other Happens always Always

Q:  Power steering works sometimes and quits completely other times. Fluid level has no impact on whether it is going to work or not. Will quit for a couple weeks and then magically start working perfectly. Have tapped on that in line valve thing with the two wires going to it but that doesn't make any difference. Had been working fine for a couple weeks and so I topped off the level with ps fluid and it hasn't worked since. Pump is spinning okay. I tried bleeding some fluid by loosening a fitting down on hydraulic cylinder, but didn't make a difference although fluid did squirt out.


A:  pump may be getting bad, or your rack may be getting bad
