I recently replaced my stock radiator with a koyo and it keeps leaking by the fan switch. Has any one else had this problem with it leaking already tighten as much as i can without breaking anything and tread sealer but still keeps leaking coolant.. someone recomend something... please

 

I had the same problem bro. You need to use a crush washer. That stopped the leaking for me.

 

thanks... It was nice meeting you today

 

No worries bro! Good meeting you too!
