Can a broken thermostat cause an engine to overheat?

Broken Thermostat Your vehicle’s thermostat opens and closes as needed to keep your engine at the right temperature. If it’s stuck open or closed, your engine will overheat, which is a significant problem. The thermostat is usually located in a plastic house somewhere on your engine block or head, check your repair manual to find its location.

Is the thermostat in place to regulate water flow?

Yes, the thermostat is in place to regulate water flow, and allow the engine to reach its proper (minimal) operating temp. With it removed, engine temps run lower and you computer thinks it needs to keep a richer fuel mix than otherwise necessary.

Why is there an anti collapse spring in the lower radiator hose?

The truth is, you must have an anti-collapse spring in the lower radiator hose if you have an older vehicle with a conventional cooling system. Because the lower radiator hose channels coolant to the water pump and engine, it is susceptible to negative pressure and collapse at high rpm. The anti-collapse spring prevents that from happening.

Why does my water pump have no crank?

If you are getting a voltage drop from 12 to 7 volts, then this is going to be the cause of the no crank. If you have tried other good batteries, then you have problems in the battery… The code P0453 is for the purge control valve; it’s most likely bad and needs to be replaced.

What happens when the radiator thermostat is stuck?

You can tell the thermostat is stuck closed by carefully touching the radiator hoses. The top one will feel hot, yet the bottom hose will remain cold. When the thermostat sticks open, the engine will never reach operating temperature, which negatively impacts gas mileage.

Which is the correct position for an engine thermostat?

Here, a typical engine thermostat is shown in the closed position (left) and open position (right). As the thermostat opens, the flow of coolant is gradually diverted into the radiator instead. Thermostats have a temperature “rating” (such as 180 or 190 degrees Fahrenheit) which is the temperature at which the thermostat begins to open.

How does the thermostat work on an engine?

To do this, the thermostat will start off in the fully closed position – blocking any coolant flow into the radiator where it would lose heat. Instead, the coolant is redirected back into the engine block to ensure it reaches its ideal temperature (around 190 degrees) sooner – regardless of how hot or cold the outside air is.

How can I tell if my water pump needs to be replaced?

Mechanics can check for coolant flow by comparing the temperature of different parts (hoses) of the cooling system. In some cars, the flow of coolant is visible in the expansion tank. If a water pump is driven by the timing belt, it is often replaced as a precaution during the timing belt replacement.

How much does it cost to replace a Honda water pump?

Many Honda owners, however, opt to replace the water pump together with the timing belt because if the water pump fails later it will cost the same labor to replace. Plus, a water pump is not a very expensive part ($45-$170).

Where are the radiator and heater hoses located?

Radiator and Heater Hoses In a typical automotive cooling system, you’ll find at least 4 main hoses. First, the upper radiator hose leads directly from the thermostat housing (on the intake manifold or cylinder head) into the top of the radiator. Attached to the bottom of the radiator is a lower radiator hose.

How does the overflow hose in a radiator work?

An overflow hose runs between the radiator cap and the reservoir tank where extra coolant is stored (and added). As pressures within the cooling system change with coolant temperature, a valve in the radiator cap allows coolant to flow back into the reservoir to relieve pressure buildup which naturally occurs.

What happens when coolant is never in the radiator?

This will only add insult to injury! When coolant never has a chance to give up heat via the radiator, it gets hotter and hotter, especially if you’re stuck in traffic. And even on the open road, coolant never has a chance to park in the radiator long enough to give up heat energy to the atmosphere. Never operate your engine without a thermostat!

What kind of coolant should I use for my water heater?

If you are using straight water, you should always add water pump lubricant and a corrosion inhibitor. Also, use a coolant enhancer like Water Wetter, which improves surface tension and heat conductivity. Coolant manufacturers often suggest a 50/50 mix of ethylene glycol and water, which will protect your cooling system down to -34F.

Radiator hoses connect the top of the radiator to the top of the engine, as well as the bottom of the radiator to the water pump. Radiator hoses are essential to keeping fresh coolant running throughout your vehicle.

What happens when the radiator thermostat gets stuck?

Thermostats occasionally get “stuck shut” which cuts off the cooling capacity of the radiator, at least partially. This often occurs after an engine has overheated for some other reason, such as when the water pump fails, or if a large coolant leak develops. For this reason, car makers usually place the thermostat in an accessible position.

Why is the water pump on my car not working?

If the hose is not warm due to warm coolant being circulated it means that the pump is not working. The water pump runs off of an accessory belt driven by the motor. If the belt is loose or worn it may not turn the water pump at the speed required to pump the coolant fast enough to properly cool the engine.
