So when i was installing my headers i broke off a sensor, Towards the front of the drivers side head under the header. Its deffinatly a coolant sensor, whats it called though because i checked autozone.com for a new one and was unable to locate my part.

 

its the sensor for the temp gauge in the gauge cluster. it might be called the temp sending unit

 

Get it from the dealer to avoid a problem. Most auto parts stores won't give you the correct one.

 

I agree...there are actually two "temp sensors". One is in the cylinder head, as you know, and one in the front of the water pump. The auto part stores sometimes get them confused.

 

I had the same problem locating that part but it's simply a coolant temp sensor for your gauge in the dash so go to autodome and get that sensor !

 

autozone didn't carry it when I looked 2 days ago but I found it at kragen's. carquest, and napa all for right around 20 dollars. Just make sure you tell them sending unit or you will get the wrong one. Make sure it is the sensor that has one big prong right in the middle and a smaller one of to the side of the connector.

 

Vatozone does carry it, its Duralast part # SU109 for LT1's. I just bought one a few days ago for the same reason.

 

Damn everyone break that thing..lol

I've done it too so we're all in the same boat.

 

No-o-o.....When I was putting in a new Opti a few weeks back, I decided to change the water pump, since it's 13 years old, as it was already off. I took the sensor out of the old pump, and as I was installing it in the new pump, the socket slipped......

 

^^That one is easy to find though..

 

here's off the LS1tech LT1/LT4 parts list section :

LT1 coolant temp sensor- gauge (cyl head) (AC-D #213-77) (93-97) = 25037332 (f. 10096151)

Here's a link for it on GM parts direct for $15.12 + shipping. I imagine its cheaper at "vatozone" but in case they're not an an option :
coolant temp sensor at GMpartsdirect.com

 

Thanks alot guys, just ordered one from napa

I probably could have avoided breaking it, but my header install was not going to good. So you could say i was being alittle "rough" with things.
Little did i know the drivers side was the easier of the two haha.

 

haha Yea, we just had this thread a few days ago! I swear people don't even pay attention to the site until they have a problem I check it almost every day, and at the longest 3 days.

Temp Sending Unit is the one in the head, Temp Sensor is the one in the water pump.

 

the one from vatozone is $14.xx I wish I had checked for the GM parts direct and pay the extra buck for the better one.

 

extra buck + probably $5 shipping.

 

+ 3 months of waiting for a stupid sensor. there super slow at shipping orders out

 

Oh... What? You actually need the part you ordered soon? Huh... Who'da'thunk'it?!

 

+18 on the temp sending unit
