I decided to use this nice day off to clean my throttle body. So I took pics.
I normally do this every spring to keep it clean. But a neglected throttle body can get incredibly filthy. Any amount of grime on there can hinder performance or throttle response.
First here are some things you may experience with a dirty Throttle Body.
- Poor Throttle Response
- Decrease in MPG
- Rough or inconsistent idle
- Hesitation when accelerating from a stop
- Inconsistent acceleration
I did this on my 2.4L 4 Cylinder, the procedure is very much the same with the V6 engines, only difference is the position of the Throttle Body.
Also I have a plastic Intake Manifold, I'm not sure if the V6's do, I'll get into why this may matter later.
You will need:
- Flat head screw driver
- 10mm Socket Wrench
- TB/Intake Cleaner
- Rags/lint free paper towels
First you'll need to remove the intake duct and the engine cover to gain access to the throttle body. Since I have an intake it was a matter of removing one clamp.
Forgive me for not being able to cover removing the engine cover, but there is one hose clamp holding it to the throttle body that you can reach from the right side with a longer screw driver, you'll also need to remove the oil cap and you can simply pull up on the cover to remove it.
Some older 4 cylinders have a two-piece engine cover that isn't as involved to remove.
I decided to remove my Throttle Body and do a deep clean.
So first thing was to unplug it.
First you have to depress the center tab and then slide it out to the right to release the lock tab.
It will slide just a bit and then it should stop here, Don't pull it any further or you can loose that locking clip:
Now you can just push down on that clip and unplug it.
Now with it unplugged you can remove the 4 10mm bolts that hold it down, they shouldn't be very tight.
Just loosen the bolts, no need to pull them all the way out, You'll see why soon.
Now we have the throttle body removed:
Now here is why I said don't worry about removing the bolts all the way.
There are little rubber bushings in the throttle body designed to hold the bolts in place:
Now the reason I can remove this and replace it is because I have a rubber O-ring for a gasket, I'm not familiar with the V6 engines, but it's been my experience that, if they have a metal intake manifold there is often a paper gasket, that would likely need to be replaced if you pull the TB.
But Because I have a Plastic intake manifold they use a rubber O-ring that is Reusable.
