Thank you for writing in. First and foremost, avoid overheating the engine. This is detrimental and will cause more problem each time it happens. Secondly, you need to find out why the fans' fuse keeps blowing. This is very likely the major cause of all your problems. The most common causes are exposed wiring that create a short, or the fans are faulty and causing the circuit to surge. Only further inspection will tell. 

Good luck!
