What is coolant bypass on throttle body?
The whole point of the bypass is to get coolant away from the intake manifold/throttle body. Just go straight from the water pipe or from the head next to water pipe (depending on your set up) and loop it to the coolant line that goes to the drivers side of the intake manifold flange.
What is the coolant system bypass hose used for?
The bypass feature allows water to flow around the engine, without passing through the radiator, while the thermostat is shut. Without it, the water will not circulate correctly creating hot spots around the engine which could lead to damage.
Can a throttle body leaking coolant into engine?
lots of cars have coolant passages that allow some coolant too flow into the throttle body, this supposedly helps the throttle body keep warm, some say to prevent “sticking because if icing.” if there is coolant leaking into the throttle body you may have un sufficent seal due to a bad gasket or mating surface on the …
What is a coolant bypass tube?
The heater bypass tube is a cooling system component found on many road going cars and trucks. It’s purpose is to serve as a cooling system passage that bypasses the thermostat, so that there is coolant flow even when the engine thermostat is closed.
Do you need the bypass hose on BBC?
The bypass is necessary to allow a small amount of water to circulate when the thermostat is closed. Without a buypass the opening of the thermostat would be delayed and the engine could develop hot spots or even steam pockets before the stat opens.
How do you replace a coolant bypass hose?
How to Replace a Coolant Bypass Hose
- Jack up the front of the car and lower it onto jack stands below the two front tires.
- Use a screwdriver to loosen the bypass hose clamps and remove the hose.
- Install a new hose and tighten the clamps.
- Lower the car from the jack stands and refill the radiator with coolant.
What is radiator bypass hose?
What Is A Coolant Bypass Pipe? As with a traffic guard, the bypass coolant pipe or hose directs the flow of coolant through the engine based on the engine’s conditions. This flow is directed by the thermostat in the engine, which closes when cooled.
How do you remove a bypass hose?
How to Replace a Coolant Bypass Hose
- Jack up the front of the car and lower it onto jack stands below the two front tires. Place a drain pan under the radiator drain valve.
- Use a screwdriver to loosen the bypass hose clamps and remove the hose.
- Install a new hose and tighten the clamps.
Why does a throttle body need coolant?
More than likely it’s not flowing through the IAC, but rather around the throttle body. In most cases this is done to keep the throttle plates from freezing when it’s cold outside. The coolant running through there can provide a lot more heat than is normally available without it, even with a cold vehicle.
Does BBC need water pump bypass?
Where is the coolant bypass hose?
Where Is The Coolant Bypass Hose? In the vicinity of the thermostat housing, there are these pipes, or hoses. You will need to follow the upper radiator hose to the engine entry port. Usually, the thermostat is located inside the engine, in a housing that is attached to the upper hose.

Why did they run coolant around the throttle body?
[body] What happens is. They run coolant through the throttle body to keep the throttle plate from freezing open (mostly in Canadia and Places in the US where it snows). So if you do the bypass it’ll take all that heat away from your throttle body and give you more of a throttle response/lower temp.
How to inspect throttle body?
Inspection Inspect throttle body Measure the resistance of the throttle control motor. Standard resistance If the result is not as specified, replace the throttle body.
How to properly clean the throttle body?
Remove the battery cables. When you work under the hood of your vehicle,you’ll be close to electrical connections.
