As someone who enjoys DIY repairs, I found this loverapple sensor to be a solid choice. It does its job well, feeding accurate data to the car's system, which helps with performance and avoiding overheating. I've used it for a short while now, and it's held up fine—no issues with readings or function. It's a simple part but crucial, and this one delivers without any fancy features. Definitely recommend for anyone looking to maintain their engine without spending a lot.
- Pros: This sensor worked instantly and gave a clear read on the coolant temperature, helping me keep an eye on the engine's heat without any fuss. It was quite easy to install myself, fitting right into the block as expected, and it seemed reliable from the start.
- Cons: The courier called ahead for delivery, which was good, but the packaging was a bit flimsy, and I had to double-check the fit to make sure it was seated properly. For a perfectionist like me, that extra step was a minor annoyance.
