what’s up guys I have a 2002 tl type s I recently swapped the trans and the car has been overheating ever since. The fans turn on for a little then turn off. I jumped the fans and they stay on for a little then turn right back off. I took it to a guy and he found the rad fan timer and it was Burnt with a hole in it. I swapped that out the fans turned on and worked fine but when I drove it for about 20 minutes and it over heated again. Any tips would help thanks
