i just went to autozone to pick up a coolant temp sensor and i think i got the wrong part. my stock sensor on the side of the block is 3 wire and the one i got is 2... what gives. if im not mistaken there is another sensor by the waterpump. did i get that sensor... im so confused lol

after some more research i have found that 98's have the 3 wire... my problem is i cant find a part number for that all i can find at the normal auto part stores is the 2 wire...HELP!!

Try, Duralast TU178 from AutoZone, or have the parts guy look up the sensor from a v6. See if that matches and post back.

I show the GM part number being 12551708 and goes in the left cylinder head on the exhaust manifold side but towards the front.

Here's the cross reference from AutoZone with pictures. Does it match?

I think thats the V6 one, isn't the LS1 temp sensor a 2 pin? Is this sensor you want in the drivers side cylinder head?

How about this one: http://www.rockauto.com/catalog/moreinfo.php?pk=929858

yeah the 98's are different. i picked mine up from scoggin dickey parts center locally. any dealership should be able to get you the part

after i fixed the sensor my car gained about 20whp

Yeah the 98s are a different part number, maybe because the temp gauge actually works in the 98s, thats why the 98 is a 3 wire instead of a 2 wire and dummy gauge for the 99s-up. I think the GM part number for the 98s is 12551708 and 99-up is 12608814
