I would like to know which sensors to buy...I want to replace all of mine, coolant, temp, O2...could someone help me on brands and all sensors on an LO3 89 IROC. Thanks much.

P.S. Anybody have a bulb chart too...wanna replace all of them too.

 

For asking what brands of sensors, it would be better if asked in the TBI forum. LO3's are TBI, right? A good brand sensor for one engine might be crappy for a different engine setup.

I have a suggestion. Maybe not replace all of the sensors, a few of them will probably never fail and if they do you will know, like the oil pressure sensor. Take all the money you saved from not buying some of those sensors and replace all the bulbs to LEDs. You'll need LED flashers for LED bulb blinkers. Shouldn't have to replace an LED bulb ever. Do what you want though, its just a suggestion.

 

IC. Well my temp guage doesnt work...and my coolant sensor was removed....so I figured (depending on price) that I'd replace them all. That and I am going to be getting an e-check and want it to be perfect...flying colors..Lol. Well thx.
