No way I know of.

A cracked manifold has no effect on the amount of air moving through the radiator.

Changing the transmission fluid depends on the type of transmission. Is your manual or automatic?

Hi; automatic. I use it as a mail car. The drive is easy but it’s constantly overheating. There’s no problem if I remove the hood. So, i’ve had louvers punched into it. Still, it overheats.

What problems will a cracked man cause? Also, upon first start up I hear a stinging like noise coming from the drivers side of the engine & also a noise from the same area almost like a click-clack… no pun intended
