The burning coolant smell in your 2003 Chevy 4x4 truck, despite no overheating or visible leaks, could indicate a few potential issues. It may be caused by a leaking head gasket, allowing coolant to escape into the combustion chamber, or a problem with the intake manifold gasket. Additionally, a malfunctioning heater core or a coolant line near the exhaust could also be to blame. It's advisable to have the vehicle inspected by a mechanic to accurately diagnose and resolve the issue.
Overheating in a 4G15 engine, even with a newly overhauled radiator, new water pump, and fresh engine oil, can be caused by several factors. Potential issues include air trapped in the cooling system, which can impede coolant circulation, or a malfunctioning thermostat that may not open properly. Additionally, blockages in the coolant passages or a faulty temperature sensor can also contribute to overheating. Lastly, inadequate coolant levels or a failing head gasket could lead to excessive heat buildup.
Why does your car overheat with your heater on?
When your car's heater is on, hot coolant from the engine is diverted to the heater core to provide warmth to the cabin. If the engine is overheating, it could indicate issues such as low coolant levels, a malfunctioning thermostat, or a failing water pump. These conditions can prevent the cooling system from effectively regulating engine temperature, causing the engine to overheat even when the heater is active. Additionally, if the heater core becomes clogged, it can restrict coolant flow and exacerbate overheating.
