Turn on the aircon and the fans should come on, at least you will know if the fans work.

If the fans don't come on with the aircon it would suggest the fans aren't working. Check the fans are plugged in to the loom properly, also check the fan relays and fuse if there is one, I can't remember.

yeah all i could suggest is make sure the plug is connected properly to the loom on the left side of the radiator. if it is get a test light make sure that the car is running with the A/C on and test if there is power to the connector (plug). seen a few that have had faulty power connections in the wiring.

hi fellas well i took out my radiator and took it to the happy wash and high pressure rinsed it replaced the thermostat with one that will open earlier i replace the bottom radiator hose because it was bolging put new tectaloy gold coolant in it and ran it it ran fan came on and now dont go any further than half way so i think it may have had an air lock also the radiator cap which was in it wasnt a recovery one just standard so it wasnt taken in any coolant from reservoir never buying parts from repco again anyway cheers fellas for all the ideas
