External Oil Cooler, let me see some pictures Options

Cool ........ can this 'cooler delete/external cooler add' retrofit be installable with the engine in place? (IMG:style_emoticons/default/idea.gif)

Yes ..... This thread describes how.

Just install the adapter after the cooler has been removed, and cover the hole in the tin when you have the cooler out.

The remote cooler adapter can be installed that way but the rest of the project is not that simple.
The warmup flaps need to be completely removed and the new sheet metal blanking plate installed on top of the stock cooler tin piece.
I think the shroud needs to be pulled forward or the cyl 3/4 top tin removed.

Chris,

Why not make a cap that fits where the rubber seal between the oil cooler and tin is connected? Then just disconnect the cable on the warmup flaps to insure they don't close.

I have a batch of adapter plates for the cooler location sitting in a box here.

Chris - any chance you have a block off plate for where the oil filter bracket goes?
So I could route to a remote oil filter bracket?

I wanted to use the sandwich adapter that I already have, but my plumbing to the front oil coolers is 12AN. The sandwich plate that I have does not have enough space between the fittings for 2X 12AN.

So I either need to come off the adapter plate with the 3/8" fittings to a remote adapter, or I need to replace the filter bracket with a plate that has 1/2" NPT fittings (3/8" NPT would work if they were far enough apart to use the 3/8"X1/2" reducer fittings).

I could go the "ful flow" pump route (probably drop the engine) or the cooler block off, but I actually wanted to keep the stock oil cooler so If I add a thermostat to the plumbing to the front coolers, I still have some cooling until the thermostat kicks in.

That way racing in cold(er) weather will not engage the front coolers until the whole system is warmed up.

Summit shows a whole bunch of sandwich adaptors with 1/2" NPT fittings, or even larger in some cases.

Thank you! - that will work!

I kinda like that idea too ..... as of now, I am still slightly attached to the stock oil cooler (IMG:style_emoticons/default/unsure.gif) ............ however I believe this oil circuit diagram for the type 4 ....... may help make a decision on where the 'additional' or 'replacement' oil cooler should be placed in the circuit ..... (IMG:style_emoticons/default/smile.gif)

P.S. I got this diagram from another site (link below, it was a changing GIF), so someone please confirm that this circuit reflects our type 4 engine case.

I guess this is an ongoing discussion ..... (IMG:style_emoticons/default/beerchug.gif)

According to this pic (re-posted below) in your thread link .... the pic I posted (above) appears correct .... (IMG:style_emoticons/default/popcorn[1].gif)

[gothspeed]

Looks like Jonsey already makes a nice billet type 4 'oil cooler delete' / 'external oil cooler add' interface plate with gaskets and 3/8" NPT thread for fittings ..... (IMG:style_emoticons/default/beerchug.gif)

Now all one needs to do, is decide how one is going to modify the flap / tin where the stock oil cooler was ..... (IMG:style_emoticons/default/smile.gif)

So I recieved the sandwich adapter plate in the link above from Summit and it fits perfectly.

There is room for the 2X 1/2NPT - 12 AN adapters and then the 12 AN straight fittings with plenty of room to work with the fittings.

I have the whole thing with filter hanging on my mockup (spare case half) and I am concerned with the weight of the assembly.

The cast stock oil filter adapter looks beefy enough to handle it, but the threaded pipe where the oil filter threads on looks like the weak link to me.
I think I will need to build a support bracket that supports the weight for any "four offs" that might occur.

Pics to follow.
