Questions & Answers

What is the possibility of this working on the 226L6 engine?

Willys Jeep Parts Tech:
Not sure about fitment for it. We have never tried installing.

Is there a specific way this piece is supposed to fit on adjusting lever?

Willys Tech:
Yes, as it expands (heats up) it should open the flap.
