I see some bad reviews on this item but all 3 sensors work fine for me in my 79 Camaro 350 sbc. During installation I paid attention to details. You may need to use Teflon tape on some connectors. They're cheap, but if you take your time and install them properly, they'll last for several years. I connected the temp sensor connector to the temp sensor first before screwing it into the engine block or it won't tighten properly and will leak. I see many buyers saying that the threads on the sensor don't reach the threads on the extra fitting that comes with the kit. Screw these 2 together first, then screw them to the engine block. Make sure you run the cable through the firewall before doing this. All my sensors work and they light up too, so I'm happy. Hope that helps!
