That is the water pump weep hole. You either misinstalled the gasket, or the new pump is bad.
low coolant? Plugged or restricted radiator? Water pump not circulating coolant? Cooling fan not working? Thermostat not opening? Cooling system air bound?
There is an engine temperature sensor that operates the cooling fan.
Check your cooling fans in front of the radiator. It could be a relay or fuse to your high speed fan motor. Also, check your coolant temp sensor, antifreeze level, and or thermostat again.
In very short: If the thermostat stays open, the warm-up time for the engine will be significantly longer, resulting in unwanted start-up wear. If the thermostat stays closed, the engine coolant can not circulate through the engine and cooling system, resulting in the engine overheating, as the coolant is used to keep the engine in a specific operating temperature.
i think the reason might be your cooling system, check the basics. the basic would be to see if there is low coolant in your engine when it is cold and in the radiator. If that is fine then check the thermostat located in your cars engine. It might be open and not checking your cars temperature right or might need to get replaced.
your thermostat is closed. needs to be replaced. inexpensive part but can save your engine from overheating.
lack of coolant . no cooling fan operation, low engine oil, improper coolant mixture, thermostat stuck, debri on radiator , restriction in cooling system.
You need to check coolant temperature sensor and the water pump.
if you take it out then the coolant would continue going through the radiator and cooling the coolant, this would never let your engine get up to operating temperatures, the thermostat opens and closes depending on the temperature of the engine. leave it alone its there for a reason
Check accuracy of gauge with mechanical one Check coolant level Bad thermostat? Cooling system airbound? Cooling fan not working? Water pump not circulating coolant?
The engine cooling fans are not functioning, low on coolant, bad thermostat,
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.
