What is the normal temperature range for a radiator?

[Emilio]

Radiator temperature is generally normal between 80 to 95 degrees Celsius. Both excessively high or low temperatures are detrimental to the engine's normal operation and performance. Hazards of overheating: When engine temperature is too high, the piston will over-expand due to heat, reducing or even eliminating the clearance between the piston and cylinder wall. This increases piston movement resistance and may even cause scoring on the piston and cylinder wall. The piston ring tension will sharply decrease, failing to properly seal the gap between the piston and cylinder wall or effectively perform oil scraping and distribution functions. This can lead to engine issues such as excessive exhaust gas and oil burning. High temperature warning: If an engine experiences overheating twice, the piston ring tension will essentially disappear, and the engine will quickly develop oil burning problems. In such cases, only a major engine overhaul can solve the issue.
