Yes, because as the water heats it expands. The water system will then spill over to the expansion tank. The expansion tank is only big enough to store expanded water at the thermostat temperature. When your thermostat doesn't open the water will over heat/ over expand. You will see brownish burnt water marks all over the expansion tank near the overflow hole. Best off just throw away your thermostat you don't really need it.

Why does heater go from hot to cold on 2001 civic also defroster not very good?
The thermostat may be sticking shut which would cause you to loose heat inside or you may just be low and antifreeze. Check your antifreeze level if it is full then get a new themostat and if that don't work your heater core may be going bad.
Why is antifreeze running out of your ford explorer motor?
Depending on the area of the leak, it could be a bad head gasket, cracked head, bad gasket on any of the housings that control the antifreeze flow i/e thermostat, water pump etc, cracked or loose hose or bad water pump.
Can a loose thermostat cause check engine light to appear?
It is possible. A more likely cause is the gas cap was replaced incorrectly or left off after getting gas
Does mixed antifreeze loose its strength when stored in vehicles?
No, it does not loose it's ability to prevent freezing but it does, over time, loose it's ability to prevent rust and corrosion within the cooling system. The inhibitors break down and cannot do their job properly. Long Life antifreeze can last longer than normal antifreeze but it must also be changed according to the interval as listed in your owners manual. There is no such thing a a lifetime antifreeze.
What would cause the pipe going from thermostat to radiator to leak?
what kind of "pipe"? solid metal pipe, or flexible rubber "pipe"? number one cause is from aged rubber that dries out and cracks. loose hose clamps, wore a hole through it, cracked thermostat housing, etc.
Is an antifreeze leak dangerous?
No. It can result in damage to the engine if you loose all of your coolant. I have damaged an Alternator by coolant spraying on it. There is some risk if you try to work on the radiator or remove the cap when the engine is HOT. The fluid can spray on you can cause burns. Antifreeze is not harmful to you if you spill it on you. ( cats and dogs are attracted to antifreeze and could possibly kill them if they drink it )

water pump leaking at seal hard lower radiator hose or loose clamp hardened or punctured bypass hose shrunken timing cover gasket thermostat gasket shrunken
Could a faulty water pump or bad radiator of a 1995 Ford Aerostar be a cause for engine overheating?
Yes...all those things can, but add a Thermostat, loose fan belt, bad fan clutch/electric fan, electric fan thermal relay (if equipt with an electric fan)...That should cover it.......Wait.....one more.....Old antifreeze too!
What would cause an antifreeze leak in a 1997 Bonneville?
Either the radiator hose is loose where it connects to the radiator or there is either a small hole in the radiator or in the radiator hose. Try checking the hose to see if it's loose or check for small holes in the hose or radiator.
Why is your ford f150 still overheating after you change your antifreeze?
If your fanbelt is old, it may be slipping or loose. If so, replace it. Aaaaand, your thermostat could be stuck. Also Check to make sure that your head gasket is not leaking, the exause could be heating, and boiling your coolant.
Would a blown head gasket cause loss of compression?
It is possible but it depends on where the crack is. If the crack is from the combustion chamber out, such as through a coolant passage it can also suck in coolant/antifreeze and loose compression.
What would cause a 1996 sable to over heat if the coolant level is full?
clogged radiator bad water pump bad thermostat fan not working loose belt
