Reviews
"Just what every guy or gal needs that has a Chrysler with a HEMI ...was surprised when checking the oil and washer fluid a couple of weeks ago there was just this annoying cap on dip stick tube that said FOR DEALER USE ONLY ...called dealer and can understand they want to make sure you only add OEM fluid as not to void warranty ... heck all I wanted to do was check my fluid level and they wanted me to make an appointment to come in and charge me $49.50 ...no way ... fit perfectly and if and when I need to add proper OEM fluid I will do it myself ... highly recommend and everyone should own a HEMI at least once if or not more times in their life."
"Nice to know the fluid level without having to go to the dealer...Due to it's "newness" the knob was a bit stiff to fully insert in the fill tube where it would lock in place, even with lubricating the "O" ring on the knob."
"simple instructions and easy installation."
"Internet forums are evenly divided on the accuracy vs the factory tool."
"love being able to check my tranny fluid instead of bringing it to a dealer."
"Fits 2013 Dodge charger 5.7."
"Nice item, exact fit, excellent quality."
