Howdy what's this gizmo ? My S1 doesn't have it Cheers |
That's the cooling fan control kit from RX8Performance, or something similar to it.
Basically, it keeps the coolant temperature lower by telling the fan to come on earlier. IIRC it keeps the coolant temp below 90 C instead of the factory 98 C. |
Thanks mate. Previous owner also fitted silicone radiator hoses. He lived in an extremely hot area. Makes sense

.... https://cimg6.ibsrv.net/gimg/www.rx8...79560ee73.jpeg Took these pics when coolant temp was 105c https://cimg7.ibsrv.net/gimg/www.rx8...3eee2cbd2.jpeg Maybe I should disconnect it ? |
Also fan comes on with ignition when cold ? |

You sure that's the radiator fan and not the secondary air injection pump?
doesnt air pump only come on when engine is running ? |
Ok cooling fan comes on when cold and stays on all the time . Checked up to operating temp. Maybe whoever did the mod didn't do it right ? So maybe just one fan is working hence it went over half when idling today ? |

Sounds like they might have forced fan 1 to operate all the time. Hard to conclude without being near the car, but faced with such a situation, I'd disconnect any wiring associated with this mod and restore stock functionality. If you still have heating problems then we can diagnose from there.

Loki so it's ok to just cut those wires off relays ? Shouldnt really need this mod with S2 |

The air pump only runs for a short time when starting up the car after the engine has cooled. It dumps air into the exhaust to help light off the catalytic converter faste.

Ok set up is back to factory but fan still comes on with ignition on which doesn't seem right |

This the correct stock setup. The extra relay in the green circle is for the optional seat heaters, and I wouldn't be surprised if Australian cars don't come with them.
The previous owner set it up wrong, BTW. The instructions say that you need to replace fan relay 1 and 2 with the provided units, except the kit is designed for S1, and while it works for S2, fan relay 2 in S1 is called fan relay 3 in S2 and vice versa, so you need to pull out fan relay 3 on an S2 and replace it with the relay in the kit. If you wish to use the kit, the two relays in the red circle are the ones you use. I also included a picture of the relay for fan relay 2. It's a different unit compared to relay 1 and 3. |
Yes I just replaced far right one with the correct blue one and no difference still please do me a favour and see if your fan comes on with ignition and stays on when started |
