[GH85Carrera]

Be sure the clean things up in the fender well and the oil cooler area first. Cover the brakes and hub with plastic, and I would suggest you order two new rubber hoses if they are original to the car. They often have seep of oil and are getting pretty old.

With new hoses threading them to the pipes was easy for me, but I really fought with getting the super fine threads to engage properly onto the cooler itself as they come in at an angle. It is real easy to cross thread them. An old stiff hose would be a real challenge to get on square and not cross thread.

For me to get them back tight enough to seal and have zero leakage required the two wrenches to be hooked to the lines at just the right angle to where just squeezing with your hands makes them scissor together. Using both hands squeeze the handles of the two wrenches together and tighten until you can't get them tighter. Clean up any oily drips with brakeclean and go for a drive until the engine is full temp for more than 15 minutes. Then inspect for any leaks.

I ended up using several zip ties to put a layer of paper towels around the connections, drove for 30 minutes, come back and inspect the paper towels for new leaks. Once I was sure they were leak free, I removed the paper towels. After 14 years and many miles they are still leak free.

My 85 came with the Carrera cooler, but no fan so I adapted a fan to it. I only need the fan when it is blazing hot outside and on long drives.
