Any advice on getting the big nut loose. I have a 2000 Ranger with the 2.5L. I need to change the EGR valve, but having getting the 1" wrench to turn the nut. It's been soaking for the last hour with PB Blaster.
Thanks,

 

either use a longer wrench, a cheater bar, breaker bar, 2 open end box end wrenches linked together, hit the end of the wrench with a hammer in the direction u need and the blunt force may bust it loose, an impact gun, or maybe apply a little bit of heat,

 

I went back out there and tried it again. Found out that because the nut is at a weird angle, I was using the wrong size wrench. Turned out to be 1 1/16th not 1". The wire harness for the PCM, firewall seals and wiper motor get in the way. Valve is changed, CEL is out and the truck is happy again.

 

Glad to hear you got it out. Before trying to remove mine, I sprayed the fasteners w LiquidWrench penetrating lubricant, let the car sit a while, then drove it somewhere to do something. Then I repeated the procedure the next day, let the car cool a bit, then unscrewed the nut easy squeezy w a small crescent wrench. I had read some of the stories about the difficulties of removing the EGR valve, so that's why I did it that way. I did not want to damage the pricy EGR pipe.

PS: WD40 is not a penetrating lubricant & has scored poor on comparative tests.

 

Came to realize that because I wasn't getting on the nut square, I was using the wrong size wrench . After getting the right size wrench, it came right off.

Liquid Wrench is pretty good stuff. I like using either PB Blaster or Kroil. Ever since WD-40 has been "outlawed" at my place of employment, I tend to stay away from it. From what I understand, it doesn't like certain metals and the residue it leaves behind will start to corrode.

 

why even mess with it mine keeps going on and off and on and off. the hell with it

 

Because I don't like seeing the CEL all the time.

 

By any chance did you use a sealant on the big nut's threads. Or use a gasket there where the pipe fits into the EGR valve?

I'm asking because the shop manual says the pipe must be replaced on the 02 Escape 4-cyl if the EGR is removed... info I didn't see until afterwards. doh.

 

I used some anti-seize on the two bolts and the new gasket that came with the valve. I just slipped the valve onto the pipe and didn't replace that, nothing was mentioned about replacing the pipe in my cd.

 

Okay, thanks. It's one of those puzzling thinsg.... to me anyway.
The 2002 shop manual says to replace it on the Escape 4-cyl, but there is no mention of replacing the pipe on the V6.
I'll figure it out. Thanks again. JMK.
