What Causes High Engine Coolant Temperature in Wuling Sunshine?
1 Answers
Reasons and solutions for high coolant temperature in Wuling Sunshine: 1. Poor radiator cooling may be caused by excessive scale buildup in the radiator preventing proper water circulation, or malfunctioning electric cooling fans. Solution: Clean or replace the radiator, and inspect the fans. 2. Faulty thermostat operation. The thermostat remains closed at low temperatures and opens at 90°C to initiate full coolant circulation. If it fails to open at 90°C, it will cause high coolant temperature. Solution: Replace the thermostat. 3. Water pump slippage or impeller detachment can impair coolant circulation, leading to overheating. Solution: Replace the water pump. 4. Damaged cylinder head gasket. Solution: Replace the cylinder head gasket. 5. Coolant leakage from the cooling system resulting in insufficient coolant level. Check for decreasing coolant level and address any leaks promptly.
