Hi, I'm needing the part # for the CTS that the ECM uses to read temperature. The one located at the front of the intake. The car is an 87 LB9 Auto. I'm in the UK so my local dealer is Suburban in Stamford CT which is 3000 miles away from where I am currently. Thanks for the help. Robert

I have a GM part number for a 92 Camaro #25036979 (Wells # SU109 is equal) This number also xreferenced by autozone.com to be for your 1987 305 "F" motor.
My AC DELCO book only goes back to 88 but almost everything from 88-2002 use a delco # 213-310 on Firebirds and Camaros.
Some odd notes about "collar button" indicate p/n 213-80 in1991 only.
all from 88-90 shows this 213-310 number.

I tried searching for those part numbers on GMparts direct and came up with nothing.

Found p# 213-928 on an acdelco website. It's the part number given for an 87.

The 213-80 number came up for an 89 350cid.

I'll try and find if I can get the 213-928 sensor here and try that.

The first number used to be a good one???
The other numbers are DELCO part numbers not GM so they wouldn't show up.
Most parts stores here would interchange from the GM number.
12146312 was listed on GMparts directs website for 87 and 92.
I don't know if that is correct for the V8.

i was typing while you were

They all pretty much look the same.

Thanks for the help. I'll try and get hold on one and hopefully that will solve my problem. Hopefully.
