HELP! broke a sensor

**rajiv1998** · 05-09-2007, 02:29 PM

when i was changin my plugs/wires i broke off the engine temp sensor. When i went to start the car, the needle to the guage was pinned all the way to the max. I drove it and when i was making a turn to come back, it jerked a bit then everything was fine again. But now myh fans keep comming on and i think the engine is overheating. Any1 know what i can do, and where to get it fixed? I need the car ASAP

The ECT sensor by #1 in the head? Just get a replacement they're not expensive - be sure you get one for a '98.

yes its near the #1 plug. When i go to start the car the temp guage doesnt work. Also i broke the little gormet off of it. The metal peices/wires are still stuck to the engine, its just the rubber peice i broke off. Do u know how the installation will be like. I looked but couldnt see another peice for it

You mean the rubber piece that's part of the sensor after you disconnect it? That's part of the brass sensor on mine. Not hard to replace the sensor, just screws in. If you need the '98 PN I have it written down somewhere and can look it up.

it is easy to replace you just need to remember that it needs to be torqued down to around 17ft lbs well that is how much it is on my car the sensor itself cost about 15 bucks well i hope this helps

That pic makes it look like the plug wire is connected to the ECT, lol. Get a new sensor, GM PN is 12551708 and lists for about $20 at the dealer - probabaly cheaper at a local parts store. Like I said earlier, make sure you get one for a '98 - they have 3 wires and the '99 and up have only 2.
