What is happening when the coolant reservoir is overpressurized and starts leaking from the cap Is this a thermostat problem or cooling fan switch problem?

Is it too full? Well some vehicles are equiped with a little hose that will let coolant out if there is too much or too much pressure, but not all vehicles will have it. (If you are talking about the overflow tank, if the radiator cap is leaking, check to see if the cap is in good condition)

Why is coolant bubbling in reservoir tank?
thermostat is stuck shut
If the coolant reservoir is being sucked out of the reservoir could this be a bad thermostat?
No it probably means you have a leak some where. Try pressurizing your system to find the leak.
Where is the coolant sensor on a 2001 Mercury Sable and is it possible to replace it without replacing the entire coolant reservoir?
NOTE: this answer is describing the location of the engine coolant temperature sensor - NOT the coolant sensor in the reservoir that warns when the level gets too low.The coolant temperature sensor is located directly adjacent to the thermostat housing. The thermostat housing is what the upper radiator hose (toward the right side of the engine compartment) connects to. You do not have to replace the reservoir to replace this part, but leaky coolant reservoirs are a common problem on this model.
How can you tell if the thermostat is going out?
Vehicle takes an excessive time to attain normal operating temperature Heat not HOT with coolant full - thermostat not closing properly Vehicle heats up too soon - No heat with coolant full Coolant boils out of reservoir or top of radiator - thermostat not opening
What causes coolant to backup and spill over in the reservoir until its all gone?
the reason why the coolant is spilling up over the reservoir is because the thermostat needs to be replaced because when the engine needs water the thermostat heats up from the engine and causes the springs to expant which opens a seal to allow the water throughout the engine i just realpaced the thermostat in my volkswagen
The coolant starts to boil shortly after starting the engine. State the fault indicated and how you would diagnose the fault?
Coolant not being circulated through the radiator/radiator fan subsystem. Most probably the thermostat is malfunctioning. Two ways to test this fault: (1) Coolant accumulates in coolant reservoir. (2) Remove the thermostat and immerse in boiling water; if thermostat does not open, replace unit.
Why is Coolant is full and engine overheats coolant is boiling in reservoir?
Tough to narrow it down with such little detail, but it sound like your car's thermostat may be malfunctioning and not controlling the temperature correctly.
How do you change a thermostat on a 2003 dodge neon sxt?
To change the thermostat on a 2003 Dodge Neon SXT, first remove the drain plug to let the engine coolant drain into the pan. Unhook the coolant reservoir and remove the hose clamp. Spray the two thermostat housing mounting bolts with a solvent and pull out the old thermostat.
Does a bad thermostat cause coolant to leak out?
It can if it is stuck closed the engine overheats causing hot air ( steam ) to flow backwards to radiator cap which releases and blows steam pressure into recovery reservoir which starts blowing out the coolant in the reservoir making a puddle on ground.
92 Camry engine coolant reservoir boils thermostat and radiator caps replaced radiator replaced 8 mos ago?
You need to check coolant temperature sensor and the water pump.
How do you get windshied washer fluid out of the coolant reservoir?
Remove the coolant reservoir, flush it out, reinstall it and refill with proper coolant.
89 Cadillac Seville seems to get really hot towhere the coolant bubbles in the reservoir what could be the problem?
Head gasket? Low coolant level? Water pump not circulating coolant? Thermostat not opening? Radiator plugged or restricted?
