I observe recently that the fan in my engine was connected directly and after a week I bought my car it begins to consume a lot of fuel that is the distance I normally cover with 14liters I now cover same distance with with almost 29liters and my call does not smoke excust pipe is not leaking , Hyundai Tucson 2008 4plug

Pls scan the car first, that direct connection to ignition might have caused it to have difficulty operating at closed loop, the engine's computer might be trying to make it enter close loop, thereby increasing the fuel trims.

I already scanned the car a nothing was found I saw the fan wire connected direct to the battery

Car probably had overheating problem with previous owner and his technicians decided to run fan direct. It is not a good idea to run fan direct or remove thermostat to prevent overheating. Fans are also run direct if engine is getting old and needs extra ventilation. My advice: If engine is in very good condition, you will need to revert to how fan should be run without by-passing necessary relays, then check thermostat, fan speed and ensure radiator is not clogged with dirts.

Your car needs needs physical diagnosis, by a technician that understands and can work with live data. Where's your location.

Wow, I'm in lagos, see other thread on car talk, you can get help there.

Connectiing your fan direct will make your car consume more fuel. Other things can worsen it too. How long have you owned the car? How did you know it consumes more fuel. From your post if I understand you clearly, you said it suddenly started consuming more fuel

Tow reasons could be adduced to y its connected that way:
1. its either that engine has an underlying overheating wahala, that mechanics have tried unsuccessfully to solve, or,
2. it was done because of the common myth about from some quarters that "our weather here is more tropical than countries of origin of purchase".

Try having that fan reverted, so you see what's going on. if it overheats, get to the root cause(s) of the problem.
