There are some good hoses replacements on the market, some industrial ones actually much better than what comes on the car. The problem is finding the proper end fittings...I'm not too keen on reusing the old fittings on new hose. I need to check for a leak on my A/C system...first I'll check with a simple halogen leak detector (Tif #5750). The problem with "sniffer" type detectors is that you have to be right on top of the leak to detect them...BMW mechanics know which components are suspect of various models and can go right to the potential problem. If this doesn't work, I'll use a UV detection system (Spectronics Tracerline TP-1700) which should be able to detect a dye at the point of leakage. The appropriate dye (for R12 or R134) is injected into the system via whip hose and cannister and circulates through the AC system through the oil carrier. Expansion valves, evaporators and condensors are suspect on BMW models. SD Steve D'Gerolamo c/o The Ultimate Garage, Emerson, NJ Tel 201-262-0412 Email.... Web Site....
