What do you use to remove a bypass hose?
Use a screwdriver to loosen the bypass hose clamps and remove the hose. In some cases, the bypass plumbing uses a pipe instead of a rubber hose.
Is it necessary to replace a coolant bypass hose?
If the bypass circuit uses a pipe, inspect the old pipe. These normally rust and routine replacement is vital to maintain the integrity of the cooling system. Tighten the radiator drain valve. Lower the car from the jack stands and refill the radiator with coolant. Start the vehicle.
Where is the bypass hose on a radiator?
The bypass hose is below the housing. The bypass hose is always much smaller than the radiator hose. Install a new hose and tighten the clamps. If the bypass circuit uses a pipe, inspect the old pipe. These normally rust and routine replacement is vital to maintain the integrity of the cooling system.
Why do I need a bypass hose for my water pump?
Car engines need a way to equalize water pump pressure. The engine is cold when it first starts, but the water pump spins even though it isn’t needed. Without a bypass route, the coolant would dead-head against a closed thermostat.

What’s the difference between a bypass and a bypass pipe?
When this happens, the coolant flows through an externally-mounted coolant bypass pipe or bypass hose. As it sounds, bypass “pipes” are rigid, non-flexible tubes made of steel or plastic – while bypass “hoses” are traditional rubber compound hoses. The design of this coolant return setup varies from automaker to automaker.
