There are three relays, all under the hood, that control the cooling fans.. No 1 is on the firewall. As you're looking at it,under the cruise control box, there will be three relays hung on a rail. The fan relay should be on the far left. This is the lowspeed fan relay and controls the drivers side fan. If it is bad, neither fan will work at all. Unclip it off the rail, spread the clips that hold the relay to the housing and pull it out. They're about $12 or $13. There are two more fan relays and one 60 amp fan fuse, in the underhood relay center. It's a black box on the passengers side of the engine compartment, tucked up in the corner between the engine mount and the wheelwell. The cover is flat and about 4" x 4". Remove the top, it has tabs on the front and back, and expose the rlays and fuses. There are two identical relays in the center of the box. The right one ('B') is the high speed relay. The left one ('A') is the right fan relay. They're identical and interchangeable. The 60amp fuse for the fan system is in the same relay center on the row of fuses toward the front of the car. The far left fuse is a GREEN 60 amp fuse. Change it also.
Blockage in the cooling system No or little fluid in the cooling system Radiator fan not working
Low coolant? Cooling fan not working? Bad thermostat? Cooling system airbound? Water pump not circulating coolant? Radiator core plugged or restricted? Bad radiator cap?
Cooling fan not working? Thermostat not opening? Plugged radiator? Water pump not working? Defective radiator cap? you have to bleed the thermostat
The radiator cooling fan is most likely not working.
Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap? Low coolant? Cooling fan not working? Radiator restricted or plugged? Water pump not circulating coolant? Defective radiator cap?
Temp sensor not working, cooling fan not working, blown head gasket.
No, regular flushes of the cooling system are necessary to keep mineral deposits from forming on the inside of the engine and radiator. Mineral deposits can partially clog the cooling system and form an insulating barrier that will keep your cooling system from working properly.
Check coolant level Cooling fan working? Dirt or clogged radiator? Defective radiator cap?
Low coolant?Cooling fan not working?Radiator air flow restricted?Radiator clogged?Water pump not working properly?Radiator cap defective?
Type your answer here... your cooling may be not working and you might have a partially plugged radiator
Hyundai got excellent cooling system, you might have a little hole in your radiator that affects cooling circulation pressure? check if you have tight cooling system pressure.COCORICO
Low coolant? Radiator plugged or restricted? Thermostat not opening? Water pump not circulating coolant? Defective radiator cap? Radiator hoses collapsing under pressure? Cooling fan not working? Cooling system air bound?
