I doubt anyone will read this,
Surprise!

the torque spec for the screw-on filter fitting (the one that tightens with the 10mm allen) is 15 ft-lb's
Thanks for that.... I just did this the other day and was worried I hadn't tightened it enough since the fitting had been so freakin' tight when I took it out.... It hadn't occurred to me to loom in the shop manual :banghead:

Anyway, I'm sure I got it to 15 ft-lbs at least.... Unfortunately probably more but it should be fine....

I'm trying to figure out how I'm going to plug both sides of where the lines were as well. I guess if I do this by an LAPS and/or a hardware store I can pick things up as I go along, but it would be nice to have it all at once and just get it done.

Does anyone have a good method of plugging the holes left behind when the hoses are removed?
A little late, but you can just do what I did earlier on page 2 - cut the lines right at the fitting and smoosh them in a vise. No leaks for me.

Or you could go all out and get a new rad without an oil cooler in it to replace the stock radiator. :blah:

If your doing the delete why not just take the part from the lines that screw into the radiator to the store for sizing and use 2 bolts in the radiator, and just pull everything else out of the van permanently? Maybe someone here already knows the size for those connectors.

Mine are not on or I would verify, but I am 99% sure that mine had the attachments similar to what connects brake lines, these are behind the clips you are talking about, screwing directly into the radiator so the lines can clip in. I had to replace my radiator so didn't go down this route, but a couple bolts would be a nice clean easy solution.

These things, I think you can remove one and take it into a hardware store.

Why bother? OIl is the only thing that goes through there, it's not open to coolant.

No need to cap off the cooler.

I'm thinking that the fitting in Wiley's photo would be NPT (Pipe) thread. PROBABLY 1/4" NPT but don't quote me on that, match it up at the LAPS with a plug to be sure.
Like Leeann said just above, there really isn't any valid reason to block this off because the only thing that goes in or out of there would have been engine oil. I've done this delete on 2 of these vans and one other GM product and never gave any thought whatsoever to plugging the ports in the rad. But that's me.
It CAN be done. BUT....just because something CAN be done doesn't always mean that it SHOULD be done!

My only concern is that if I ever decide to put them back in, I might have a bunch of crud in the radiator that will flush through my motor.
But a simple garden hose flush could fix that I guess.

The fitting on the radiator, that the oil line clips into, unscrews easily from the radiator. Pull the upper one out. Put some duct tape over the hole for a coupe of days, while you are making a trip to the local NAPA store. I am sure somebody there can fix you right up with a couple of fancy plugs.

Thank you for the good instructions. I removed the oil cooler adapter and lines from my Astro to address the persistent leaks. I think you are right on rationale. We live in MN, so not much really hot weather, and we're not towing heavy loads or using the van for a taxi. I will monitor and report back.

I would also like to add that I had to drain a couple quarts of oil on the side of the road the other day because i added 5 quarts (these vans take 4.5), and after the cooler delete the oil level was like 3/8" of an inch above the hashmark.

Didn't really do anything for about 50-60 miles (I read that these vans aren't that incredibly sensitive to oil levels), but the possibllity of frothing the oil was driving me nuts, and then I remembered "Oh yeah! The cooler delete!".

I don't know how much less oil the van takes after the delete, but it seems like it's a pretty considerable amount, so anyways, I finally just decided to drain a couple quarts (good thing I keep my drain pan on me), and just add a half quart at a time untli it was 1/8" below the MAX hashmark.

Just had to have that piece of mind.

Ran like a freaking top with zero oil leaks, zero pending codes, excellent fuel trim, and excellent oil pressure the entire time I took it on it's recent 3-400 mile adventure.

Thanks for making this thread!

A bolt is usually free, but if you dont have 2 laying around it will cost what, 2 dollars, just use a bolt if you want to, no reason not to use one, no real reason for using one....who cares, like you said itkeeps out dirt, and critters, and cleans up the look. Glad the delete worked out though, not sure why everyone seems so worked up these last few posts, no reason to act like dicks, gman is excited to be working on the van.

Well said.

You can say that again. But we won't complain about it - LOL

The "oil cooler delete" is great! Glad to see others do it themselves too.
Draining oil on the side of the road.. not so sure about that one.
No one was "worked up"... was mostly just curious about a few things.

[I retracted my comments from the permanent record.. :D ]

I'm glad to see gman's excitement and success too.
It's a good mod!

OK since it is gone, Mmusicman wasn't being a dick, now it looks like I called him out and he cleaned it up.

With gmans reaction to his concern of to much oil, I actually agree with it. We are not all mechanics, and constantly learning about these vans. Sounds like he knew he had too much oil, but was not sure how much of a problem the extra 3/8ths would be, so decided to take action there since he could rather than possibly damaging something out of ignorance. As for the side of the road, there are many places in the US which are very rural, and have a lot of "side". He may not have had any parking lots for miles, maybe he is in the countryside. As to carrying the tools, he only really needs a socket and small container to drain some oil, maybe a jack if he can't reach in or it isn't lifted, but who doesn't have a jack and a socket with them?

Mmusicman had a good point about your math gman, I think you were just explaining it poorly, but make sure you did not remove too much oil.

In the future it is probably much cleaner/easier to remove the extra oil via a tube and the dip stick.
