What is the function of bypass hose?

Bypass Hose: A bypass hose allows coolant to return to the engine if the temperature is yet reached. The thermostat remains lock, blocking the coolant if the temperature is not yet obtained to open the valve. So, the coolant bypasses the radiator as it follows the hose.

Should I replace water pump with thermostat?

Most of the time, RRT will recommend replacing the thermostat at the same time as the water pump. In almost every case, the thermostat is located adjacent to the water pump and needs to be removed to access it. This saves you labor as you usually only would need to purchase the part during this job.

When replacing a water pump What else should you replace?

The most common related services accompanying water pump replacement are cooling system flush, testing the radiator cap, and possibly flow testing of your radiator to make sure that the radiator is not clogged.

Do I have to change water pump with timing belt?

Generally, the idler pulleys, tensioner and water pump should always be replaced when the timing belt is replaced. In most cases, the timing belt drives the water pump, so it is the right time to replace the water pump. It is also recommended by the manufacturer.

What happens if a timing belt breaks on a non interference engine?

If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.

How much does it cost to get a new timing belt?

The average cost to replace a timing belt will be anywhere from $300 to $500 in total (more for larger cars, trucks, and SUVs). The timing belt itself will usually only cost less than $50 but the majority of a timing belt job is spent on labor. The cost of the labor will be anywhere from $250 to $450 or more.
