Seat Inca Overheating Problem
Summary of the thread
A 2001 Seat Inca with a gasoline engine is experiencing overheating and a check engine light issue. The initial suspicion is a faulty radiator fan, potentially caused by a malfunctioning thermal switch or speed sensor. The problem was resolved by replacing a defective speed sensor and the thermal switch, costing 250€.

Thermal switch? Where is that located, and how do I check its function?

The thermal switch is usually near the radiator and controls the fan motor. If it's faulty, the fan won't activate when needed. A speed sensor could also cause it. If you're not comfortable testing yourself, a workshop visit might be a good idea.

It was a defective speed sensor. Replaced it, and a new thermal switch too while at the shop. Cost 250€.

Overheating and a check engine light? Radiator fan issues can be tricky. Does the fan run at all? Have you checked the radiator thermal switch?
