Anyone still having problems like me on this EGR Temperature Sensor Switch? I was able to find the Corvette switch which is identical to my original 1989 IROC 5.7 TPI, but the new EGR I got from O'Reilly had a much smaller tapped opening than original factory. Can't unthread factory base and swap either. Anyone know of a thread with similar problem/solution?

 

i got my EGR from oreilleys . the number is .17085813 CTF-080-62N . but the critical part is the .080 opening

 

Okay: will go back in the morning with this additional info. So they do have the right base with the larger tapped opening? Does O'Reilly now carry the temp switch?

 

yeah their EGR fits and works well . as for the temp switch , i have no idea . i need one too !!

 

I found the temp switch at Midwaymusclecar
EGR Temperature Switch 85 86 87 88 89 Chevrolet Chevy Camaro temp z28 305 350
Item# 261546601887 $55.00 USD
This was cheaper than the corvette supply places. I know the 1986 Corvette temp switch fits, so you can search this way.

 

midway appears to have just one part for us , and its the EGR temp switch

 

I ordered this from Herko Automotive:
Ordered Qty Product Title
1 New Delphi EGR Valve EG10125 For Chevrolet Pontiac & Oldsmobile 1985-1989

 

12doplumbing....That number is showing for the 89 V-6

1989 Chevrolet Camaro RS Coupe 2-Door 2.8L 173Cu. In. V6 GAS OHV Naturally Aspirated

 

F*^# I am getting sick of these mistakes. It came today, and without a tapped port for the temp switch.

 

the oreilly ones are ****....the last one i replaced only lasted 3 months....with one of the strictest smog requirements being in california found this one works perfect. direct fit. ac delco 214-5538 gm #19210684 its from a corvette. this has found to pass ca loaded dyno smog test and no check engine light. this can be found on ebay all day. buy the delco one.

 

was wondering what year of vett
