Rear Mounted Auxiliary Oil Cooler, An alternative to the front mounted unit Options

[earossi]

I can't locate the post; but someone was asking about mounting the front auxiliary cooler for a 6/ conversion project. I had responded about an alternative that involves mounting a cooler and cooling fan in the engine bay of a 914. I have attached several pictures of such an installation. This was not my car; however, my installation was essentially the same as depicted in the attached photos.

The cooler and fan carried a price tag of less than $400. To install the cooler, you have to fabricate some brackets as shown in the pictures. You'll need to route 12 volts to the cooler which incorporates a thermostatic temperature switch to actuate the booster cooling fan when oil temperatures reach a predetermined point. You'll also have to fabricate two short jumper hoses to take suction from the engine mounted oil cooler.

There are a number of these installations out there, including the one in my car. Several are running down in Dallas and work well.

Installing this rear mounted cooler deletes the need for hoses to be routed to the front of the car, and for body modifications needed to mount an oil cooler in the front trunk. The cooler is available from Savage, or from any number of suppliers.

I've done three coolers under the rear trunk, sold two kits for the engine lid mount, and did one with the cooler in the right rear 1/4 panel below the sail panel.

I don't like the idea of pre-heating air going into the engine compartment, or oil lines going up to the lid.

The cooler in the 1/4 was the cleanest, but most difficult. It did require a stone shield for the cooler/fan sandwich.

For ease and least amount of trouble, I'd recommend under the trunk.
