Got 4 different ones. napa, carquest. 2 from autozone, lifetime warranty. spec says opens between 184-196f. this opens at 192f and194F. almost same as stock high sensor. car now runs at 3/4 gauge hot before starting fan. before at 1/3 of gauge. never above 1/2. cracked the head when i got it that hot in traffic. the new high temp ones open at 203-toast. The car has NO wiring issues or bad grounds, just a sensor that opens at too high a temp. (in water on stove) called the manufacturers. they no makey. said they make one sensor that fits all applications. and new cars run hotter. same sensor for 55-83 corvettes. same problem tech guy said. Who has the correct temp sensor ? what do you all use ? if i have to, i'll cut the connector off a car at the boneyard and splice it to fit another style. thanks C300
