Customer Reviews (4.8 / 5 · 5 reviews)

Isabella I. ★★★★★

This plastic feels thicker than the factory one, and the cap seals tight without any wobble. Took about ten minutes to swap in on my JL, and the level marks are much easier to read now.

Benjamin P. ★★★★★

Installed it on my Gladiator and the fit was perfect—no trimming or modifications needed. The plastic feels sturdy and the level markings are easy to read through the translucent wall.

Sebastian E. ★★★★★

The translucent plastic is thick enough to see the coolant level at a glance, which saved me from guessing. Installed it in my JT this afternoon and the cap seals tightly with no leaks.
