Accidents can leave more damage than what appears on the surface. A car may look fine from the outside. But sometimes there is deeper harm underneath. One major area often affected is the floor pan. This is the part that supports the interior and connects to the vehicle’s frame. Hidden damage here can lead to safety risks. That is why mechanics use careful steps to find it.

Visual Checks Under the Vehicle

The first step always starts with a close look. A mechanic places the car on a lift. This allows a better view of the underside. The floor pan is checked for dents holes bends or weak spots. They look for signs of cracks or ripples. These may show that the floor pan has taken impact. Surface rust is also checked. But this alone may not show deeper issues. A trained eye is needed here. A small mark may reveal a much larger problem.

Advanced Scanning and Diagnosis

Some repair shops use new tools for deeper checks. Thermal cameras can find heat spots. These spots can show where stress or damage lies. Digital scanners can also read the shape of the car. These can help find dips or bends in the metal. This gives proof of hidden floor pan issues. One such place with these tools is European Auto Repair in Nova Scotia, Canada. Their scans help find problems others may miss. These modern tools make the repair work more precise.

Testing the Floor for Movement

Next comes the pressure check. The mechanic applies force to different parts of the floor. If the pan moves or gives way then it may be weak. The metal may have bent from the accident. This test shows if the strength of the pan is gone. If it creaks shifts or makes noise then something is wrong. The floor is also tapped with tools. A hollow sound may mean air pockets or hidden gaps under the surface.

Frame and Structure Alignment

If the floor is hurt then the frame may be off too. The alignment of the frame is tested with machines. These machines check if the car’s shape is still true. The doors and windows may be tested next. If they do not close right then the frame has moved. This step is key in spotting damage that is not visible. A strong floor pan keeps the car stiff and safe. Without that the whole vehicle is at risk.
