Mike, As I indicated previously, this oil cooler system (not the flange) is the standard oil cooler for the 5 cylinder N/A and turbo Audi (and Quantum) engines. On the car in the yard you can also take the baffling for the air duct. As for the flange, I have used the remote oil filter kits available from the FLAPS. The end plate adapter is generally well made and the kits are inexpensive. I moved the oil filter to the passenger side fenderwall. Easy access for changing under the car and it gave enough room to use the Mann filter made for the Volvo 760 turbodiesel. Biggest filter around. Same internal specs as the smaller ones specified for the gas and 4 cylinder diesels. In my plumbing, I routed the oil from the engine to a Mazda RX-7 oil cooler, then from the cooler to the filter and then filter to the oil return at the original flange. I kept the original water to oil heat exchanger in place ... just added additional capacity. I also left the thermal bypass valve on the RX-7 oil cooler. Until the oil warms up to 210F (I think), the oil cooler is internally bypassed. System works very well. At least 35F oil temperature reduction. And, because of the thermal bypass, it doesn't get overcooled. BTW, mounted the oil cooler (more than 2X the size of the GTi) above the trans with ducts and thermally operated fans. Fittings accessible through the passenger side wheel well. Modest attempt at humor: Vanagon was up on the rack at friendly trustworthy local (Pasadena) mechanics shop. Had the engine running. Mechanics assistant had long shoulder length fluffy hair (and scruffy beard). Assistant puts his head up near front of transmission noticing small radiator. Bank of 5 muffin tin (12V) fans kicks in and his hair quickly raises up and is sucked into the front of the cooler. Panic (on his part) mirth (on mine). Fortunately, I had wired in a kill switch for testing. New mechanic will no longer approach underside of car. Oh, well I still entertain a dastardly chuckle at the image. Frank Grunthaner |
