hello everyone! just wanna take this time and say hi to everybody here. I'm tryin to learn more about these 5SFE toyota tough motors, i have two of them that i'm currently workin on, and it's kickin my butt so far. the cooling fan dnt work at all even after start up, i replaced the cooling fan switch and the sender unit and i still cant get it to run, do i have to look into replacing the relay now? any insight would be great thanks !!
