ACDelco GM Original Equipment 213-928 Multi-Purpose Temperature Sensor

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.

Good quality OEM part, fast shipping!

Difficult to install, depending on vehicle. Aside from installation, worked first time. Exact Fit GM Engine Temp Sensor, Original Equip ACDelco Part. When you use the best, you expect the best. Excellent.

Very accurate. I replaced the stock Sniper sender and this one is much better

Easy in easy out. Works great. Half the price of the parts stores!

Exact replacement, easy to install

Fit my 2004.5 LLY Duramax coolant temp sensor. High quality OEM.

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.
