Car overheating diagnostics
Can a coolant top-up solve repeated overheating?
A leak, circulation problem or another fault can remain and needs investigation. It may not address the cause.

Car overheating diagnostics — planning the work
For car overheating diagnostics, the vehicle specification and condition determine suitable checks and parts. Some work needs workshop equipment, so describe the available space and the fault before confirming a mobile visit.
