2002 Kia Sportage Gas Smell
The squeeling most likely is the belts and that they have not been tensioned properly OR they have become glazed and need replacing.
Suggested Repair
The cabin fuel smell should fade if the injector hoses and O-rings were the source; if it continues, the leak has not been found and needs further diagnosis. The squeal is most likely a belt that is loose or glazed—check tension and replace glazed belts rather than dressing them.
Conversation Summary
Owner of a recently purchased 2002 Kia Sportage with 63,000 miles reports a strong gas smell inside the cabin, mainly in front and when stopping or using the heater, after the dealer replaced fuel injector hoses and O-rings. A new engine squeal was also noted, with suggestions of a failing water pump or belts needing dressing. Expert advice is that the fuel smell should dissipate unless the source was missed, and the squeal is most likely improperly tensioned or glazed belts that need replacement.
