Why does my throttle body have coolant lines?

Why does my throttle body have coolant lines?

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 throttle body have coolant?

All modern vehicles run coolant through the throttle body, VW is no different. This is no “factory mistake”.

What does a throttle body heater hose do?

There is a Throttle-Body Heater that is attached to the left side of your throttle-body. (blue arrow) This heater keeps your throttle from freezing in the wide open position by circulating hot fluids through it, thus heating it up and transferring the heat to your throttle-body.

Why would a throttle body be heated?

The reason for the heat is to prevent icing as you suggest. Even if that’s not an issue for you, rerouting the coolant will not really gain anything in the performance department. The amount of heat transferred to the incoming air is miniscule.

Does a bigger throttle body increase HP?

In addition to increasing acceleration performance, larger throttle bodies can also boost overall horsepower. This gives the engine increased power and torque, which may be helpful in situations such as towing. Commonly, adding an aftermarket throttle body can increase engine power by 15 hp to 25 hp.

How much horsepower will a throttle body add?

A bigger throttle body means more air And since the engine is basically a large air pump, increasing the air intake level will increase the engine’s power output as well, in some cases by up to 15 to 25 hp.

What does the throttle body coolant bypass Mod Do?

All the TB coolant thing does is reduce intake icing that can happen. If it was a lot bigger it could warm your intake air, potentially trading off a tiny amount of performance for some fuel economy, but it’s only large enough to prevent ice buildup. Only thing this mod does is make it easier to remove your TB for cleaning annually.

Where are the coolant hoses on the throttle body?

On the bottom side of your throttle body, there are two hoses. These hoses bring hot coolant through your throttle body and like the pads, assist in cold weather startup. Do you realize how much better your truck runs when it’s cold, (temp gauge at or below 160)? When it gets warmed up, (gauge at 205-210),…

How much does a coolant bypass hose cost?

To get to it, I’d have to remove the Throttle Body, the EGR stuff, the Plenum, the injector rack, the intake manifold just to get to a $10.00 hose. But wait, it gets better. Take a look at this picture, and you will notice there are two Knock Sensors. So I figure it might be a good idea to replace them while I’m in there.

When to add fuel to throttle body coolant?

Generally, the computer will add fuel at lower coolant temperatures until it reaches operating temperature. The hose coming from the rad will reach the block you don’t even need a coupler. The hose coming from the rad will reach the block you don’t even need a coupler.
