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.

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).

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 to do if your water pump overheats?

Place a funnel into the upper radiator hose. Important:Use a 50/50 mixture of antifreeze (refer to vehicle service manual for correct coolant) and deionized water. 4. Slowly fill the cooling system through the upper radiator hose with a 50/50 coolant mixture until the coolant comes out the coolant air bleed hose. 5.

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.
