EGR Nut question.

[2003 mustang gt modded]

Hi, Searched can not find answer.

What way does it turn? I know that different makes/models it turns opposite.

Also is there a special handyman way to get that huge nut off? It's suezed on there.

Thank you.

So starting another thread can sometimes not be the best way to get the info you want. You can simply change the title on the first thread and then those that read it get all of the back ground. Just wanting to point out that you can change the title.

Lefty loosey righty tighty, just remember on the valve you're looking at it upside down. Are you asking about the nut on the valve itself or in the header?

I would like to find out for both upper and lower, I think if upper nut is really stuck on there , then loosening lower one will reduce risk of braking tube.

The best way I've found over the years is to unbolt the EGR from the intake then loosen the tube from the header with a crowfoot. I have a small set of torches and use a brazing tip to get a little heat on it. Then put the EGR in a vise to loosen the tube from it. Still broken a few in my time.

If you run with EGR blocked that means your combustion is higher temperature? Can that damage engine?

So both upper and lower are non reverse threads?

Yes, turn left to loosen and right to tighten.
