You should have pressure in the cooling system. The radiator cap is marked as to how much pressure it is designed to hold, usually 15 to 17 lbs.
No, a blocked thermostat would not force water out of the radiator. A blocked thermostat would prevent the proper flow of coolant through the engine, leading to overheating and potential damage to the engine. Water may overflow from the radiator due to other issues like a malfunctioning radiator cap or pressure buildup.
To pressure test a radiator cap, you will need a radiator pressure tester kit. Remove the radiator cap, attach the pressure tester to the radiator neck, and pump it up to the specified pressure level. Observe for any leaks or pressure loss to determine if the radiator cap is functioning properly.
If there is no fluid coming from the radiator to the thermostat housing, it could be due to a blockage in the coolant system, a faulty water pump, a stuck thermostat, or low coolant levels. It is important to investigate and address the issue promptly to prevent overheating and potential damage to the engine.
The thermostat regulates coolant flow through the radiator by opening and closing based on the engine temperature. When the engine is cold, the thermostat remains closed to allow it to warm up quickly. As the engine heats up, the thermostat opens to allow coolant to flow through the radiator and dissipate the heat.
Without a thermostat, the coolant continuously circulates through the radiator hoses, causing them to heat up and expand. This can make the hoses feel very firm due to the increased pressure from the heated coolant. The thermostat helps regulate the flow of coolant to maintain a consistent temperature in the engine.
coolant in engine enters radiator at the bottom, goes up thru radiator and exits radiator at top. i would think your radiator is clogged up try a good,(expensive) radiator flush to see it that fixes proble,
check that the thermostat was not put in upside down. also check radiator cap pressure
Drain the radiator down half way. At the engine end of the top radiator hose is the thermostat housing. Remove the hose and 2 retaining bolts and remove the thermostat. Clean the surface good and install the new thermostat. Refill the radiator.
No, a blocked thermostat would not force water out of the radiator. A blocked thermostat would prevent the proper flow of coolant through the engine, leading to overheating and potential damage to the engine.

The thermostat is in the radiator. Open the radiator lid and pull the thermostat out.
Does the radiator cap hold the correct pressure? Has the coolant been in the motor for a very long time? Is there alot of scale buildup on the inside of the radiator? Is the water and antifreeze mixture right? Is the cars oil pressure good? Is the thermostat stuck closed? Any of these will do it.
check for a stuck thermostat. to do this simply squeeze your air in take line once your engine has warmed up and if it had pressure your thermostat is OK Check the fluid in your radiator to see if there is enough and if it is still in good condition,
You could have a bad water pump causing no coolant flow, inoperable radiator fans, a coolant leak,............
first, make certain the thermostat is not installed backwards, if still hot then remove a radiator hose and see if coolant is discharged with pressure behind it(this checks the water pump); it is also a good idea to flush the cooling system; make sure there is not debris in front of the radiator; beyond all this you may just have to have a professional diagnose it
Your radiator might have a small pinhole in it, causing it to not build up pressure.
The thermostat is located in the upper radiator hose. The radiator hose will need to be removed to get to the thermostat.
Steam? Leak? overheating due to low coolant? Back pressure due to a bad thermostat? Defective radiator cap? have system pressure tested to determine location of leak
