I believe that's the thermal switch for your EGR.mkelly85 said:On my '83 SD, I discovered a valve with two nozzles right next to the temp sensor on top of the thermostat housing, the nozzles were busted off and the two hoses hanging there. What is it?
I thought it looked like it was EGR related, but I wasn't sure they came equipped with them. It's a CA car though. So forget about it? I can pull one from a junkyard if it matters at all.AzimuthAviation said:I believe that's the thermal switch for your EGR.
