The Pumas will be smarting after losing to the Scots in Tucuman
Scotland attack coach Gregor Townsend expects his side to face an improved Argentina in the second and final Test.
The Scots opened their account with a 24-16 win at the weekend but Townsend has warned of a Pumas backlash when they meet in Mar Del Plata on Saturday.
"They won't play as poorly as that next week," Townsend told BBC Scotland.
"They looked tired at times and not as aggressive as they were in November. They'll come out firing and we'll need to up or game."
The boot of Dan Parks scored all of Scotland's points in the opening win and Townsend was content ahead of the second Test at the Estadio Jose Maria Minella.
"I'm very proud of the players and extremely happy with the result," said Townsend.
"It's a very tough place to come and play; no international team has beaten Argentina in Tucuman. So, to get the result and the way we managed the game in the second half was very pleasing.
That's two away wins we've had: at Croke Park and Tucuman, and another win would be a real step forward

"From an attacking point of view, we played some positive stuff in the first half and threatened a very good Argentine line.
"That's where our points came from: penalties they had to give away when we got in behind them."
Scotland have struggled to score tries in recent times but Townsend is more concerned with the momentum a winning run generates.
"It's really about scoring more points than the opposition. We had more opportunities to kick penalties at goal and Dan kicked really well," he said.
"This was our way of getting points because we were putting them under pressure.
"We can do a lot better as there were two clear chances for scoring and that would've put a bit of daylight between the teams; that's where we have to improve."
Townsend said Scotland enjoyed lots of scrum ball in the victory over the Pumas and he also praised the Scots at the lineout.
"It means we can get our backs on the ball and if you see how many times Max Evans got a touch of the ball on the wing - never mind the centres - it was great to see.
"This will be a really tough match to get that second Test win.
"To come away from home, that's two away wins we've had: at Croke Park and Tucuman, and another win would be a real step forward."
