The Overlooked Hero: A Guide to Roadside Radiator Cap Replacement in Malaysia

More Than Just a Lid: The Job of a Radiator Cap

Symptoms of a Failing Radiator Cap

• Unexplained Coolant Loss: If the cap isn't sealing properly, coolant can evaporate out as steam, leading to a gradual drop in the coolant level.
• Overflowing Reservoir: A bad cap can allow coolant to push into the reservoir but fail to siphon it back, causing the reservoir to overflow.
• Engine Overheating: If the cap can't hold pressure, the coolant will boil at a lower temperature, leading to overheating, especially under load or in hot weather.
• Collapsed Radiator Hoses: If the vacuum-release valve in the cap is stuck, it can cause the radiator hoses to collapse inward as the engine cools.
