Q: What precautions should be taken and what steps are involved in inspecting and replacing pcv hose and various hoses on Ford Ranger?
A: Be careful when dealing with air conditioning hoses. You should replace it by a dealer service department or specialize air conditioning shop. The system must be depressurized before disconnecting any hoses. Rubber and plastic hoses can decay because of high temperatures. Check hoses regularly for cracks, loose clamps, hardening, or leaks. Look for cracks, leaks, and blockages in the PCV hose. Vacuum hoses are color-coded to match different systems and marked accordingly. Hoses and fittings need to be labeled for reinstallation purposes. Inspect plastic T-fittings for cracks. For detecting leaks, use a small piece of vacuum hose instead. Be prepared to catch spilled fuel when disconnecting fuel lines. Check rubber fuel lines for deterioration, chafing and cracks. Use only high-quality fuel line for replacement purposes.
