Engine Coolant Temperature Sensor For GMC Chevrolet - Direct Replacement, 12146312 15326386 TS10075
About this item
If your Chevy or GMC is running rough, getting bad gas mileage, or the check engine light is on with a temp code, this little sensor might be the fix.
It's a direct replacement engine coolant temperature sensor.
It tells your computer how hot the engine is so it can adjust the fuel mixture and timing.
This one is a direct fit for a ton of GM applications, and it replaces a bunch of OEM numbers: 12146312, 1236302, 1338450, and 15326386.
It also crosses with aftermarket numbers like TS10075, ST069, 805218T, and SU109.
It's not a universal part—it's specifically made to fit where the old one came out.
Just unplug the old one, screw this one in, and plug it back up.
It's brand new, unbranded, but built to OE specs.
If your engine's temp gauge is acting weird or you're troubleshooting a cold-start issue, this is a cheap and easy part to swap out.
