I jsut put my s4 rad into my s5, my s5 was broken.

I now have the low coolant sensor dangling, and thus, its always going off. what do I do with this wire now? is there a sensor on the s4 rad?

 

yes. its at the to[ om the very very middle.

 

isnt that a bleeder cap...

 

Its in the center top of the radiator. There is one brown wire that should be coming out of it. If its not there (broken off) and you dont want to hear the buzzer you can ground out the wire that is suppose to hook up to the sensor. It will shut off. Be aware you will NOT have a buzzer for low coolant if you do this.

 

I have the hole in the middle of the s4 rad, but there is a bleeder screw in it, and the hole looks to small to put the sensor in

 

Both S4 and S5 radiators are supposed to have the same level sensor in the same location, i.e. middle of the top tank. The only bleeder is the one on the upper hose connection on S4 radiators. If you don't have the sensor in the right spot it's because someone's removed it and screwed a plug into the hole.

 

ok thanks a lot

 

just ground the sensor wire. just be carefull when driving though
