Frequently asked questions
- Why is my car overheating?
- Coolant temperature above normal means heat is not leaving the engine. Continued driving risks a warped head and a bill ten times bigger.
- Is it safe to drive with this?
- No. This symptom can leave you stranded or cause much more expensive damage — get it looked at before driving further.
- How much does it cost to fix?
- The most likely repair is radiator replacement, which runs $235–$1,140 in the US including labour, or $90–$480 in parts if you fit it yourself.
