FORT WORTH — Jimmie Johnson still knows how to get to Victory Lane in Texas, even from the back of the field on a track that has changed significantly since his first six wins there.
And while heating up in the cockpit because of an issue with getting fluids during the race.
‘‘I’m not feeling the best, but we got into Victory Lane,’’ Johnson said before going to the infield care center to get treatment for apparent dehydration after his 81st career victory.
Crew chief Chad Knaus said there was some kind of malfunction with the system in the car during the O’Reilly Auto Parts 500, but wasn’t sure what the problem was.
‘‘Jimmie felt like it was an isolated situation,’’ Knaus said. ‘‘We got him cooled off, and he’s looking good. He’s ready to go have a weekend off like the rest of us.”
Johnson, who last year won his record-tying seventh NASCAR Cup Series season championship, charged under Joey Logano with 16 laps to go to take the lead. And the rest of the way, the Hendrick Motorsports driver kept his No. 48 Chevrolet in front.
‘‘I guess I remembered how to drive, and I guess this team remembered how to do it,’’ Johnson said. ‘‘I’m just real proud of this team. What a tough track and tough conditions. We were really in our wheelhouse, and we were just able to execute all day.’’
This was the first Cup race in Texas since the 1½-mile facility was reconfigured and completely repaved this year. It was Johnson’s seventh career victory at Texas, and sixth in the last 10 races there.
Kyle Larson, the season points leader, finished second for the fourth time this year. Logano, pole-sitter Kevin Harvick, and veteran Dale Earnhardt Jr. rounded out the top five.
Johnson had to start at the back of the 40-car field because of a tire change after a spin in qualifying. He had qualified 24th.
‘‘Oh, probably on the second or third run I knew we were in good shape,” he said. “From there, off we went. It was so tough those first 23 laps in traffic. The air was very turbulent. The track wasn’t very clean.’’
