Exhaust Manifold EGR Fitting 97 Chev Astro/GM Safari

Recommended Posts

Hello, I will replace a leaking EGR Tube from exhaust manifold to the EGR Valve. 

However, existing fitting is rusty and may be damaged.  So the idea is to replace the Exhaust Manifold fitting as well.


Since this item is discontinued from the dealer, I will/should be able to get one from a Hydraulics Supplier if I can find out what the size/specifications are.


Is there anyone monitoring this forum who can provide the small straight thread size and type and the flare (JIC) size, etc.

 I'm having the same problem trying to locate an EGR fitting that replaces the discontinued GM 12552329 part.  Did you have any luck finding a substitute?  Any help would be appreciated.  Thanks.
