I just ordered a new rebuilt 3.0 engine, from oeri, for my 4runner. Are there any parts or anything else that should be replaced while I'm putting in the new engine?

 

Water pump and oil pump unless these are included with the new engine, also send the injectors out and have them cleaned, also clean the intake and throttle body.

 

ok thank you. what about sensors? should I replace any of those?

 

If everything is working fine now then you don`t really need to replace any of them. The only two sensors that i would consider replacing if they are original or have a lot of miles on them would be the 02 sensor and the TPS, other than that, if everything is working ok, then don`t worry about it.

 

ok thank you
