213-928 (15326386) Engine Cooling Temperature Sensor

Worked perfectly and much more accurate than the one that came with my aftermarket fuel injection system

GOOD PART

Identical to OEM for 1991 Chevy 1500 Silverado 350 in fit and finish. For some time truck has been hard to start. Sometimes the gas pedal had to be floored to get started, then I'd have to jack the pedal until the engine smoothed out. More recently it began idling fast, but otherwise running ok. Finally, a week or so back, after it warmed up, it would die as soon as I gave it any gas. By cranking while flooring the gas pedal, I could restart it fairly readily, but it would exhaust a fog (un-burned gasoline). Clearly truck was being flooded (this tbi truck engine evidently is among those designed to clear intake by cutting fuel delivery when pedal is floored, which is why it would start with pedal to the metal). Had to disable one of the two injectors (removed one injector connector) to keep truck running long enough to be able to move it out of driveway (running on one injector worked, whereas on two the engine would die, indicating too much fuel was being injected). If you have good spark at the plugs, timing is right, compression is good, fuel is being delivered, and air filter is reasonably clean (and you otherwise have good cranking) - this is most likely your no-start/hard-start/flooring-required-to-restart issue. Easy fix. Be careful when removing the connector-if as old as mine, the catch is brittle. Loosen old CTS until it can be turned by hand, then quickly swap with new. If engine is cold, loss of coolant need be no more than nominal (relieve pressure first if engine is warm). Proper tool is 19mm deep 6 pt socket, but 3//4 6 pt works fine. With this new CTS, my Silverado is running like new, and I expect I will get much improved fuel economy with this new ACDelco 213-928 CTS.

Was having a hard time with the cold weather and stalling inconsistently, narrowed it down to the coolant temp sensor (not the temperature sending unit sensor on the side of the block... different part #) swapped this out in the driveway and runs better than it had probably run in over 10 years! 10/10 exact replacement for 350 small block GM. Would 100% buy again

Go with OEM.

fixed my intermitant miss problem with rough running

Direct fit for 2005 Silverado

Simple install if you have a large deep socket. My OBDE scanner reports an operating temperature to be around 190-195 degrees. But my GMC 5.7L Vortec has two temperature sensors. This sensor (locate at the radiator hose inlet - supplies data to the ECM. It is accurate (so was the old sensor). But there is another temp sensor (one-wire) located below and between the #1 and #3 spark plugs. That sensor reads directly on the dash gauge. It is not working properly so I'll need to replace it.

Changed the temp gauge reading, worked perfectly

Pieza original para gmc sierra k1500 5.7 1994

Funcióno muy bien en mi camaro 1997, tengo 2 meses y no me ha dado problemas.

My Crusader 454XLi fuel injected (TBI) was idling really high when warm, about 1000rpm. It also ran awfully rich and was fouling plugs. Turns out this little sensor was the cause of all that grief, I initially thought it was the idle air control, but nope. The old sensor was leaking coolant from inside the electrical connectors. Not good! Glad this sensor seems to perform great so far, as the Crusader one is over $100!

Made in Mexico NOT china. Better quality.
