    Hi everyone, wondering if theres any experts out there. I got a 2010 Hyundai and the radiator fan is not working. If I ground it and supply power directly it turns on, I've checked the fuses and relays and it doesn't have the typical ones. It's a multi fuse junction box and the connector looks perfect. It also is drinking up coolant from the reservoir a lot.

    Bad fan switch not making a ground???You’ll need a radiator pressure tester to find your leak. some autoparts stores may have a loaner program for that tool. If you can’t find a leak, check your oil for signs of water and raising the oil level. It maybe seeping into the cylinders and burning off. Check your spark plugs look for a really clean one it’s usually the one. You may even need to take your plugs out and pressurize the system over night to see if antifreeze seeped inside the cylinder/s. Good luck hope this helps.
