I plan on it, it's $6. Just wondering if it could cause the EGR not to work, I know coolant can be hell on electrical connections and other mechanical parts.ImperialCrown said:The upper hose could also leak if the aluminum outlet pipe got 'crusty' oxides where the radiator hose pushed onto it. There should be no external leaks at the radiator cap. It's cheap enough that I would replace it if this is the case.
The short EGR pipe fitting and short rubber hose to the base of the black, plastic transducer carries exhaust gas pressure to indicate the amount of exhaust back-pressure to the transducer. I have seen plugged cats push more exhaust through this pipe than it should and melt hoses and transducers.
The transducer halves do come apart and the inside diaphragm can be inspected for water, rust and tears. We know that the transducer solenoid works electrically, but it can fail inside here as well.
As long as the vacuum hose from the booster shows no kinking and delivers good vacuum to the solenoid, you should be OK.
Is there anyway to take it apart? I didn't see any way. Since they are sold together, I would rather not pay $200 dealer price. So, anyone know a good website to get OEM genuine Chrysler parts?Bob Lincoln said:It should hold vacuum, so you may have a transducer diaphragm leak. They often tear and cause this failure mode.
Yeah, I can always buy them seperate. I cannot use Advance Auto. It refused to let me purchase anything and see prices, because they do not service my state. Know any other good stores? I do not want to use Autozone or O'Reilly for parts again, they tend to use the same crappy manufaturers and rebuilders.Bob Lincoln said:The EGR valve does usually come with the gasket. Haven't seen them supply new bolts, but that's not a show-stopper.
