Installation note: Please keep in mind that this part may not solve your idle issue, but it certainly doesn't hurt to replace it. It is often challenging to diagnose a Vanagon running issue, because these vehicles don't have modern on-board diagnostics. If you plug in this part and it does not fix your issue, you still own the part. Click here for more information about returning electronic parts. 

At GoWesty, we know materials matter. Do you ever wonder why OEM polymer parts seem to last many years, but often the replacement part will break down in a matter of months? That is because manufacturers had to support every part of their vehicles for at least ten years or suffer the consequences of customer dissatisfaction and ultimately loss of sales. The devil is in the details when it comes to polymers—not all are created equal! You can have two identical-looking parts in your hand and one of them might be completely crap. If you have a Mean Green GoWesty part in your hand you can rest assured it is made of the very best, no-holds-barred material for the application.

Whether it is FKM (Viton) or HBNR, we make them green so you can tell it is a genuine, properly engineered, maximum durability part only available from GoWesty!
