I was disappointed that the heater stopped working after just a couple of months. It fit well with my GMC, but I expected better durability. I’m not sure if I just received a defective one, but I wouldn’t recommend it based on my experience.

Decent but had a few hiccups
This Dorman DEF heater is pretty good overall, but I did encounter some issues during installation. The instructions weren’t super clear, so I had to figure things out on my own. Once it was in, it performed well for my Chevy, so I'm satisfied with the purchase.

Excellent replacement for my truck
I replaced the diesel exhaust fluid heater on my GMC with this Dorman model. Installation was straightforward, and it works like a charm. The heat output is solid, ensuring I don’t have issues during the colder months. Definitely a good buy if you need a reliable OE fix!
