Jolyon Palmer is insisting that Renault conduct a thorough examination of his RS17 chassis following the Brit's heavy crash a week ago in Australia.
Palmer hit the tyre wall in Friday's free practice in Melbourne but failed to finish the race when the brakes on his repaired RS17 became stuck.
Subsequently, he wants his team to check his car for any residual damage before taking to the track in China next weekend.
"Obviously I had a big crash on Friday so we've changed a lot of parts on the car," said Palmer.
"We just need to have a good look and make sure everything is working as it should. I trust the guys will do that, they're experienced and know what they're doing so I have no worries on my side.
"We just need to have a good look and make sure we're in a good position to start in China."

Palmer endured a miserable start to his 2017 season, suffering gearbox issues early on and a fuel pressure problem which thwarted his efforts in qualifying, leaving car and driver as the slowest pair on the grid.
Sunday's race brought a retirement after just 15 laps when the Renault's brakes anchored as Palmer was making progress in a car he felt was acting better.
"It was much better," he said.
"The start was good, I think on the softs, we struggle compared to the guys on ultra-softs, but still it was looking sensible.
"It was a shame because it would have been good to do the race distance and see how we ended up, and also it would have been good to have more mileage.
"Those laps, that's my personal best [consecutive laps on track] across a race weekend and four test days."
