Rear fender oil cooler mount details, How I did it Options

[r_towle]

I think it’s a great idea!
Look at the 550 type loevers in the fender, those would be perfect, and age appropriate to let air in.

How about a scoop that pulls air from under the car and directs it up? First I’d see if it meets you needs the way it is. Looks like a clean installation to me.

Hi Perry, I was wondering if you have an update regarding the effectiveness of the cooler in this location/configuration.

Thanks

I just finished plumbing the cooler, thermostat, and return line to the tank, as well as wiring the relay for the fan. It’ll probably be a month or so before the engine gets installed. Here’s some follow up photos of the install.

Oil lines fabricated and fitted. Isolation mounts not installed yet.


Oil lines to thermostat, not yet secured

Thermostat mounted


Custom return line to tank. It’s M26 at the tank and -12AN at the thermostat. I fab’d two brackets to route the line under the engine mount and clear of all the cables.

To the tank.


Fan is mounted directly to the cooler with special heavy duty round zip mounts that go through the fins. There’s a dense foam pad between the pressure points.

Rubber isolators are a perfect 30mm tall. I did have to cut off some of the stud on the end that bolts through the inner fender.


All mounted up.

I added a couple hose separators. I still have to fab a couple brackets and a stone shield.

The fan has a relay that has a switch under the dash.

As far as the efficacy, I have no doubt this is sufficient. I did the same type of install for a 3.0 conversion using a smaller cooler 27 years ago and it worked very well. This cooler is probably 20-30% larger.

[IronHillRestorations]

Wrapped up the details. I wired a relay with a fuse for the fan, and mounted it to the battery tray.


I fab’d two small brackets to hold the stone shield.

[IronHillRestorations]

Brackets installed.


I made the stone shield from a piece of plastic I got from Jay Mikesell ( RIP, former owner of PartsWerks). It’s the same material he used for the inner fender liners.

How does any air get to it?

Won't the fan take care of that?

This is getting a fully rebuilt EFI engine, which is going to run cooler than a 60k mile engine. It’s also got a double grill engine lid (and a stock one too) plus the cooler is a bit oversized, so I’m confident the cooler alone could be enough, but the fan is insurance. In the discussions with the owner, I told him I would add another cooler/fan setup under the rear trunk before going to a front cooler.

It’s an occasional use street hot rod. I don’t think it will see much use on really warm days either.

This is a 73 911 RS cooler I installed in the rear trailing part of the LR qtr.

Great for a street car, no running lines up front.

It fits so well its almost like it was meant for that application, sadly they are uber expensive now.

Beautiful work, Perry. Looks great! (IMG:style_emoticons/default/smilie_pokal.gif)

What a great idea, running a 911 loop cooler in the rear fender of a 914. Not only no lines going all the ways to the front, but front trunk and spare tire fully preserved. And the late Bruce Anderson was a big fan of the loop-style coolers. If someone needed to, could this be reversed and run another one in the RH rear fender?

I wonder if this is an idea for @mb911 ?

Man if I could find a bunch of loop coolers I would make a bunch up. Pretty easy setup.

Maybe i'm the only one confused here but how exactly does that clear the rear tires?

Fair question, though it looks like the interference points are above the tire? (IMG:style_emoticons/default/idea.gif) The tightest spot in the rear fenders is often between the inner fender and the tire sidewall? Another photo or two might be illuminating, as this is a pretty extreme angle.

On the other hand, could a for-purpose loop cooler for the 914's rear fender extend the hard lines forward, over the top of the tire / close to the top of the inner fender, so that the fittings for the rubber lines are in front of the tires, whether high or low? Would extend the cooling area and shorten the rubber line runs…
