Tevez spent four months absent from the City squad after a row with boss Roberto Mancini, but Aguero has insisted that those problems are now behind the pair.
"Carlitos is very well, he wants to help our team in the remaining games," Aguero told ESPN Radio Rivadavia in Argentina.
"As an Argentinian, I want him to be well. Luckily the situation was solved.
"Both of us played well against Norwich and he did well when he came from the bench against Chelsea, making the assist for Nasri's goal, so now there is peace [between Tevez and Man City]."
Tevez scored a hat-trick in the Citizens' 6-1 victory over Norwich City last weekend.
