Yes, a bad EGR (Exhaust Gas Recirculation) valve can contribute to engine overheating, even if the thermostat has been replaced. A malfunctioning EGR valve can lead to improper exhaust gas recirculation, which may result in increased combustion temperatures and strain on the cooling system. Additionally, if the EGR valve is stuck open, it can cause a loss of power and efficiency, further exacerbating overheating issues. Regular maintenance and diagnostics are essential to identify the root cause of engine overheating.

Replaced thermostat on 24 valve 3.0 Ford Taurus and still over heating?
A thermostat is one cause of over heating engines.The "Related Question" below lists a few other suspects to investigate that can also contribute to overheating.
How do you fix a furnace main gas valve that is stuck in closed position - Thermostat does not always cause main burner to light?
If your main gas valve is stuck in the closed position, it must be replaced. This condition is the reason your thermostat will not cause the main burners to light.
My heater will blow but not hot ive replaced the thermostat?
Check into the temperature control valve--this is different than the thermostat.
What are the common causes and solutions for an overheating water heater?
Common causes of an overheating water heater include a malfunctioning thermostat, sediment buildup in the tank, or a faulty pressure relief valve. Solutions may involve adjusting the thermostat, flushing the tank to remove sediment, or replacing the pressure relief valve. Regular maintenance and inspection can help prevent overheating issues.
What causes a hot water heater to continually run?
The Thermostat and Temp and Press Valve is faulty and needs to be replaced. or the PRV (pressure reducing valve) is dirty and must be replaced
Will a faulty thermostat on a 2003 Lincoln Navigator cause a heater control valve to leak?
A faulty thermostat in a 2003 Lincoln Navigator can affect the overall cooling system and potentially lead to overheating, but it typically wouldn’t directly cause a heater control valve to leak. However, if the engine overheats, it can increase pressure in the cooling system, which may exacerbate existing weaknesses in the heater control valve, leading to leaks. It's essential to address both issues to prevent further damage to the vehicle's cooling system.
8 What would result if the thermostat were to be installed upside down Why?
If you look at the bottom of the thermostat you will see the spring wrapped around the valve that goes up & down to open & close the thermostat. The spring is made from heat sensitive metal and is what opens and closes the thermostat as it expands & contracts. If the thermostat is installed upside down, the spring will not be in the coolant and will not open until it gets hotter than the specified temp of the thermostat and could cause overheating problems and coolant flow issues.
1991 jeep Cherokee Inline 6 with thermostat on front was overheating so I checked and replaced valve cover seal still overheats after running for more than 10 min?
changing the valve cover gasket will not fix an over heating problem u need to check out the cooling system. Radiator, water pump, hoses, belts
How do you fix a furnance main gas valve that is stuck in open position replaced thermostat and new wire no help worked fine last year?
You replace the gas valve.
Your 96 LHS is overheating and you replaced the thermostat The radiator hose keeps getting stiff and the car overheats How can you tell if it is a water pump issue or a head gasket?
It could be your head gasket... is it blowing blue smoke out the back? or you could have a messed up valve or something It could be your head gasket... is it blowing blue smoke out the back? or you could have a messed up valve or something
After you replaced water pump thermostat and both fuel filters on a 1986 Ford F-250 diesel and is overheating and has white smoke while idling or let of gas what could be wrong?
The white smoke could be valve stem seals. The overheating could be a partially blocked radiator. Don't bother trying chemicals to clean it out. Take the radiator to a shop and have them professionally clean it. could be a blowen head gasket!
Does valve cover gasket going out cause engine overheating?
A failing valve cover gasket itself does not directly cause engine overheating. However, it can lead to oil leaks, which may result in low oil levels or oil contamination. Insufficient oil can impair engine lubrication and cooling, potentially leading to overheating. Additionally, if oil leaks onto hot engine components, it can create smoke and may indicate other underlying issues that could contribute to overheating.
