Advice on changing manifold on 2005 4Runner?

Hey folks
Seems like driver side exhaust manifold is leaking, leaks during accelerating & also at cold /high idle. Anyone changed manifold on T4R, need some advice I know it's a pain, moderate skills needed...wanna see if I can handle. Check engine light is ON as well. Haven't had a chance to run the codes yet.

 

Its not that bad, there's some vacuum lines at the back i believe, you should be able to remove the throttle body and set it aside without disconnecting the coolant lines and losing coolant.

I wouldn't pull anything apart until you read the codes though
