Engine Coolant By-Pass Hose

Engine Coolant Bypass Hose Replacement: Get Them Discounted Online

What is a Engine Coolant Bypass Hose and what does it do?

The engine coolant bypass hose gives coolant somewhere to flow if the thermostat on the engine is closed. It returns the coolant back to the radiator, allowing it to flow in circles until the thermostat is open and the coolant needs to enter the engine.

When the vehicle first starts, the engine will not need coolant and the thermostat will remain closed until it reaches running temperatures.

When should I replace my Engine Coolant Bypass Hose?

You should replace your engine coolant bypass hose any time that it is leaking or clogged. In addition, if it is cracking or getting brittle, you should go ahead and replace it.

What happens if I don’t?

If the engine coolant bypass hose begins to leak, you could lose a lot of coolant and run the risk of overheating your engine. On the other hand, if it gets clogged up, you could force coolant into the water pump and destroy it.

How to do it: Replacing your Engine Coolant Bypass Hose:

  1. Jack up the front of your vehicle and put jack stands in place to secure it. Chock the rear wheels in order to further secure the vehicle.
  3. Put a drain pan in place under the drain valve for the radiator in order to catch the coolant. Open the valve and let fluid run out of the radiator until the coolant level is below the bypass hose.
  5. Loosen up the clamps on the bypass hose with a screwdriver and take off the hose. If you can’t tell the difference, follow the other hose to the engine. The bypass hose will be below the housing of the upper hose and it is smaller than the primary hose.
  7. Remove the bypass hose, then replace it with the new bypass hose. Tighten down the clamps.
  9. Tighten up the radiator drain valve that you previously loosened. Top the radiator off with coolant until it is back to the normal levels.
  11. Start your engine and let it get up to a normal running temperature. Make sure that there are no leaks from the radiator or hoses. Turnoff the engine and give it time to cool off, and then go ahead and check the coolant levels again.
