Frequently Asked Questions

We're always here to help. If you can't find your answer, ask Rydon - our AI assistant will help you out.

How do I know if my thermostat is bad?

Common symptoms: engine overheating, slow warm-up, or stuck temp gauge.

Should I replace the gasket too?

Always — even if it looks fine. MAHLE thermostats include the correct OE gasket.

What temperature should I choose?

Match your OE spec — using a different opening temp will trigger codes on most modern engines.
