I took a little break from working on my truck today and decided to dig out an old Ford oil cooler adapter, to piddle with and clean it up. I had found the adapter in a wrecking yard back in the mid-'90s.

It's for a 429 Cobra Jet/Super Cobra Jet (the number on the adapter is D1ZE-6881-AA) but, it'll bolt onto any Ford engine from a 170 six cylinder to a 460. --I see identical adapters on ebay, from time to time, going for $200.00-$350.00 dollars.







This is what the factory adapter-to-block gasket looks like.



I don't have that gasket so, I made my own out of teflon.









Some information on this factory oil cooler adapter as well as other factory oil coolers that Ford produced.

Oil Cooler

 

Just in case you need to know Steve, the D1ZZ6881A was specific to 1969 BOSS'9 and 1971 Mustang 429 S/CJ cars. Don't forget the EAA6749A gasket for that bolt head.

 

Thanks for the info. I have the small gasket for the head of the long, hollow bolt. I just didn't have the larger gasket to go between the adapter and block.

Are all the gaskets still available for these?

 

I also have a couple of other filter to block adapters.

I pulled this one off of an '80-'86 F-350 DRW with a 460. It isn't plumbed for an oil cooler. My guess is its main purpose was for engine to frame clearance by re-positioning the oil filter.





I pulled this one off of an '87 E-350 DRW Super Duty with a 460.



Unfortunately, part of the threaded boss is broken off. I have the piece that broke off but, I'm uncertain if it can be reattached.



All three adapters, side by side.

 

Not from Ford. I don't know if I'd trust NOS gaskets. But Green sales amongst others has COAZ6A636B and EAA6749A. 800-543-4959.

 

Thanks for the information, Jeff.

I have a Ford plate type (better than fin type) automatic transmission cooler, on my '69 F-100, that I robbed from a '92 F-150. It measures 11" x 5-1/2" x 1-1/2".



This is the plate type engine oil cooler I had pulled from the '87 E-350 DRW Super Duty, (from the same vehicle I got one of the filter adapters from). It also measures 11" x 5-1/2" x 1-1/2". I plugged the ports, bead blasted and primed it today.

 

I was able to get the complete adapter, lines and cooler from a ex CV 351 police car, I know there are not too many around but you never what is hiding in the back of some old yards.

 

Yep. If you look around, you can find some pretty neat performance upgrade parts for cheap.

I had forgotten about this one. This past summer, I found a 5.0L Explorer in my local wrecking yard and I pulled the GT40P heads off of it. While I was at it, I grabbed this water-to-oil heat exchanger off the engine.

 

I have one of those, goes in between the filter and block on the 351W

 

You have the heavy duty fine tooth gear set, in case you didn't know.

My dad had a '71 429SCJ Mach1 and it did not have a factory oil cooler. Not to say that it wasn't removed, but it did not have one on it when he got it.

 

The following link talks about that. It seems the SCJ 429 oil coolers were either dealer installed or were over the counter items but, there weren't any known installations from the factory.

Oil Cooler

 

Gotta love previous owner's handy work (I'm being facetious here). I went to unscrew the oil filter fitting from the block and I couldn't get the socket to stay on it. --the hex of the fitting requires a 1-1/4" socket. After I shined the drop light over on it to get a good look, I could see why the socket didn't want to stay on.



My 1-1/4" socket is a 12-point. I couldn't get it to hold without slipping off so, I had to go to the parts store and buy a 6-point 1-1/4" socket. After I drove the new socket up on the mangled fitting with a hammer, I was finally able to break it loose and unscrew it from the block.

This is the reason my 12-point 1-1/4" socket wouldn't unscrew this fitting.



I don't understand what they (previous owner) thought they were trying to accomplish here --stop a leak?????? --which could have been possible since there's a film of red RTV on the filter seal mounting pad but, this fitting isn't something that's likely to leak. Either way, it doesn't make good sense for the fitting to have been messed with or to have put RTV on the filter mounting pad.

This is a comparison of the regular filter fitting on the left and the oil cooler adapter fitting on the right. --although, the hex of the fitting shouldn't be chewed up like this.



Later model Ford engines don't have the large 1-1/4" external hex on the oil filter fittings. The hex is inside the hole where the filter spins on. It requires a 7/16" Allen wrench to remove/install the later model filter fitting.



Later model filter fitting below.

 

87147-S91 is the part number for the "o"ring 6881 adaptor to block. Still available from Ford. 1980-87 460's. Both truck and Econoline. EAA6749A is the bolt gasket. Discontinued but DeQueen Ford in DeQueen AR shows 9 of them. 870-642-3604.

 

Don't separate that Explorer cooler/adaptor. The seal in-between them is not serviced separate by Ford.
