Are the ac hoses hard to replace in the 911 or 930. I see two that snake through the engine compartment?
The hoses are not difficult to replace. As a matter of fact most of the Kuehl hose upgrades are installed in the same places that your original hoses were located in. Replacing the hoses is usually half of your work. The Kuehl Condenser Installation Guide walks you through the sequence of hose removal and installation. The two hoses coming into the forward section of the engine compartment are really not that difficult to replace once you read the instructions of how and where. All you need to replace the hoses are standard inch size wrenches, a floor jack and two jack stands (common tools). We won’t kid you on this section of your ac upgrade, the hoses are one half of the job, however, a very important part of the project if you want to eliminate refrigerant leaks.
