I bought this van sight-unseen, through pictures on the phone, and a fairly informative carfax. It was the only AWD within range (I was also shopping AMC Eagles) and still it required a 300 mi delivery. I paid more than the actual value to me, but the functional handicap conversion made it difficult to negotiate down. Anyhow, she's mine. And pretty doggone clean overall. It seems to have had an easy life, and my mechanic's gut tells me it HAS to have been garaged for a large portion of that. I haven't all the way been underneath yet, but what I can see looks to be in great mechanical shape. Therefore, I am confident that this will be more of a Preservation Project than a restoration.

Before it was even delivered, I'd seen a youtube about the disaster zone that can be caused by a rotten drip rail and old weatherstripping, and gobby attempts to fix it. The very first thing I did after parking in the driveway was pop the hatch. It was a hot mess, the whole area. Debris was blocking the roof gutter, and muddy drifts were running down everywhere, soaking the interior rear corners from roof to floor, and the carpet squished when you knelt on it. And, boy, the smell. I found 2 small dime size rot holes, hidden by cracking household caulking. Just god-awful, and I was a whole day cleaning before I could tell what was what.

After a lot of money and time, more than one would hope, I've torn down, cleaned, and reconstructed the entire dutch door seal setup. Some new parts, some original parts reused, a dab or two of liquid electrical tape, lots of adhesive. I gotta say, I think I did it, I'm no longer finding water where it shouldn't be. Here's a high-res shot of how good it's looking now. You can find my "consumer reports" on the new parts I used in the "Exterior" forum.

And onto the side slider, which I already knew was a problem as well. You could see daylight around the upper custom panel, and the headliner is rusty wet all the time. It's pretty easy to see why, more caulking.

Here's what's left of the custom upper track roller, the only thing holding the top of the door in was about an 1/8" overlap of that worn out pin. Lucky I like bicycles and have junk drawers, because a small bearing and some hardware let me fix this on the fly. Wow, just like that, the door opens and shuts smooth, and the inner seals are working. No more daylight or water from that area.

I still have to deal with those leaks in the upper "dormer," however, but I feel much better about things now than when she first arrived.

Augidog,
I have never seen an Astro/Safari wheel chair adaptation. Thanks for showing it.
It is strange the things that pictures do, and/or do not, show. Some are intentional and others sometimes show things that are not intended. In your case the pictures from the PO left out some 'small details'.
Hopefully most of the issues will be relatively minor, and you happy with the end result.
Keep the pictures coming. We are all learning, albeit at some of your expense.
Many of us have fought with the water intrusion issue around the rear doors...and many have won the battle via one method or another.

Rockridge, its moments like the roller fix that make me feel blessed to have a basic instinct for that sort of thing. Zero out-of-pocket and no searching/waiting for parts, always a good thing.

Rod, not wanting to distract from this thread but only report forward progress, and because the parts are relatively new on the scene, I posted detailed reviews in individual threads as a public service.

Tell me what else you'd like to have a look at, and I'll hook you up. PS I'm a former Machinist Mate USS Chicago CG11. Old-school oil-fired boilers and GE steam turbines. THAT was some serious gear-heading.

This, along with the passenger seat power lift/swivel, is coming out.
Don't know if they have any appeal or value, but to me they don't.

You might see about donating it to a local "Center for independent living" organization IF it works. Some places will take it off your hands to help their customers. They might even give you a tax credit for doing so. I know my local organization would love to have it, as most places like that are always short on items to help their customers (more need than supply). Just a thought.

It works. As a Veteran who has received a lot of help over the years, I won't have a problem donating it to a worthy organization. Where you located? Come take it out and it's yours. That offer is 1st come 1st served, I've also called the local DAV.

I am LOVING this! On the Oregon coast, it's wet even when it's dry. Especially overnight. With the rear and sliding doors sealed up, the interior no longer looks (and smells) like a terrarium in the morning.

Time and money well spent.

Today I will try to get the front end off the ground for my first good look underneath.

A level picture on level ground. Obviously, the accessibility equipment has to go.

Still recovering from back surgery, I can't use the creeper very well, so this is the best I can do for now.

It looks about right for a gentle 100,236 miles, but for a 25 year old vehicle it looks great IMO. Original steering and suspension is still tight, and the bushings I can see have plenty of life left.

Fluids are full and relatively clean. Based on this picture, what would an experienced owner suspect is the source of the leak? Whatever it is, it isn't drastic, at least while parked, I only have a few drops on the driveway after a month.

Oil cooler lines probably - super common problem
 
#12 ·
Agreed, you can see them in the last pic, def the problem. I cut my leaky lines and clamped on new ones successfully based on the write up here, but every year or so they would end up leaking, so I finally did the oil cooler line delete....have not decided if it is permanent yet, but it probably is.

Nice van

Thank you. I appreciate the confirmation, and I DO believe I got myself a fine specimen. My worry was that someone was going to tell me a hard to reach and/or expensive component was dripping onto the lines. Life is full of surprises, and not always good ones.

I can afford new OEM lines, but I'll look for that write-up about cutting and clamping. I suspect it will have something to do with being easier, and not about the money. About the delete...I won't ever be towing more than my utility trailer, and highway driving will be rare, so...any more opinions based on experience?

I have done it, definitely didn't see a change in engine temp, don't have an oil temp gauge, but I will be doing it to my latest Astro as well once I get around to it. Trying to get my son to help out/learn as much as possible. Just makes everything take 10times as long as he doesn't have as much spare time as I do.

I did it on my '02 when the brake lines all exploded; the brake fluid finished off already-leaking lines. That was in the fall, so I didn't drive it in a MD summer like that. The oil pressure increased and I never saw any temp-related problems, but it was winter and I didn't tow anything. And then I bought my '05 in the spring so I didn't drive the '02 when it warmed up, then a tree branch fell on it and finished it off.

The ones on the '05 are leaking and I have new ones to replace them with. I have a new radiator and new trans cooler lines (they're also starting to leak) and my plan is to do all of that at one time.

OK, who killed my spammer? I was gonna flirt with "her." Seriously, though, I was in the process of reporting it when it disappeared. Good job.

Thanks, both of you. I'm gonna do it, the delete, knowing i can always rebuild the adapter (do failing bypass valves contribute to the blown hoses I wonder) and install new lines if I choose.

I'd love to pull it, but I'm in Michigan, so it's a little far away for me. ;)

As for your oil cooler lines, usually it's where the rubber hose section gets crimped onto the aluminum tubing. This is very common on GMs, and has been an issue for over 20 years, since they started using them. Something to think about, the early model A/S's didn't use an oil cooler at all, and some of them have a ton of miles put on them. My wife's old 86 Astro had well over 232K on it when the engine finally took a crap.We got it well used from a contractor, and I don't think it was ever serviced, or was only serviced when there was a problem before we got it. I think she put 45K miles on it, before I replaced the engine, then she put another 25K on it before I pulled the engine and trans, as the engine went into her gold 90 GMC Safari (bought with a rod knock for $400), the trans went to my dad for delivering the van from Texas for me. But a friend of mine has a 91 full size pick up with the same oil cooler set up, and replaces the lines every couple of years, as even new replacements do the same thing (leak at the crimps). To make things worse for him, his wife drives a 4x4 S-10 Blazer, and those hoses run to the remote oil filter too (similar set up, but with 4 of them (2 in, 2 out)).

I used to have a link bookmarked from S-10 forums on oil cooler line fixes, but that was on my old computer that took a dump. But the idea was to replace the hoses and crimps, with dedicated transmission rated hose, and screw clamp the new hose onto the aluminum lines. I can't remember what the longest time they survived without leaking was reported though.

As far as towing with the oil cooler delete, I don't think it'll be an issue, as the early Astro-Safari's didn't even use an oil cooler, and could still tow 3K pounds or more. I know my own 88 Astro towed a VW behind it for about 1000 miles once, and I've pulled a utility trailer with multiple quad runners on it (with fuel jugs and beer coolers) several times, going up north, along with pulling my tear drop camping trailer several times.

Wandering around the forums while I wait for the rains to stop, and for my "crew" to arrive in June, I've been asking a lot of stoopid questions. I haven't owned or worked on anything for almost 20 years. And I've never owned anything but carbureted engines, and never engaged in any OBD except for the paperclip to look for codes. I have more learning to do, engine-wise, than I originally thought when I bought.

This isn't the first time my enthusiasm has gotten the better of me, and I needed saving from myself. After my latest stupid question about Techron or other cleaners, a realization punched me right in the nose.

This van sat on a car lot for a year, and during that time it had a little over 200 miles put on it. This jives with the 1/3 tank of gas it has left. They probably tanked up when they bought it. I haven't been driving it while I untangle some legal issues. I only warm it up around the block about once a week. Fluids are clean with no signs of mixing. It starts and runs good, with various stutters.

But how the HECK can I know anything about its current state of tuning, or make plans, when I'm running old fuel that likely has (some) water in it? Since I'm in no position to drain the tank, I'm going to have to make do with additives.

I was looking for advice, couldn't wait, went with what I DO know...tanked up with 92 octane clear, added Lucas injector cleaner and a bottle of Heet.

wowsers. now I feel double-dumb for not doing this right away.

I don't know when it was last test-driven, but if they'd kept fresh (dry) gas in it, it might have sold before I ever found it.

I'm beginning to think twice about it needing engine work. I'll put the scanner on it and record some data, but boy howdy it runs much better than I first thought.

It's amazing how much better these vans run with good fuel in them. ;)

heck, anything for that matter.

with that epic dumbass-moment behind me, I've been reassessing...

After 50 miles of good fuel, the engine doesn't seem to need anything at the moment.
80% new Toyo Open Country A/T II P215/75R15 (at 44psi these are excellent tires)
Front brakes, new pads, replacement rotors fairly recently. .
Rear brakes, new shoes, new hardware.
Steering is tight.
Handling is soggy. KYB Gas-a-just front shocks are on order. Still have to remove bulky handicap equipment.
Drivetrain has something that's not quite a clunk, and only occasional when between R and D, but I'm inexperienced with AWD and haven't identified it. Shafts, u-joints, cv-axles, all pass wiggle test. It could be it's only a wheel slipping and I'm not used to how full time AWD feels.
Y-pipe and exhaust studs look good, recently new universal CC, needs pipe/muffler/tail. Walker parts install scheduled for Tuesday.

Dutch Door and Liftgate seals are performing well.

And for anyone who's been waiting for this...I'm bananas for my new nuts
<-- look who's back!

Now that I'm driving it, I'm ever more in love with the mechanics of the vehicle. I always knew I would be, I said that in my intro. I also said it was cosmetically more than I was looking for.

I am NOT enjoying the liabilities that come with a 25 year old conversion. I don't want the running boards but I also don't wanna know what's under them. I like the hi-top because of my height, but it's sagging and cracking more than the pictures show. The plush interior was never to my taste, and at its age it looks more desperate than luxurious.

Drivability is proving itself better than I'd hoped for, so I'm willing to go all-in on the body, but I'm a little afraid to start looking for prices. New simple hi-top and body work after taking off the running boards, that's not going to be cheap. It's either that or just drive it into the ground, but I like it too much to do that.

EDIT: feedback on hi tops will be appreciated. so far, I've found fiberine, but haven't made contact yet.

I believe my 2000 had a rough life in VT hammering down bad roads. Even after replacing all front end steering parts, ball joints, and shocks, sway bar bushings (poly) and end links, it is still soggy feeling compared to my 04 that lived in Baltimore MD. Way more body roll and it just doesn't feel tight like the 04. I think the torsion bars are fatigued. Given the extra load of the wheel chair lift, this could be the case with your van. You could try turning up the torsion bar preloads. The 2000 felt a tiny bit better after more preload. I turned them just before new tires and alignment. LT tires also.
