99 Tahoe
Hello everyone! Just purchased my Tahoe today with the hopes to resurrect it. Ended up going from and S2000 to a Tahoe so a big momentum shift. So far i'm having a few problems. I found a radiator fluid leak between Spark plugs 8 and 6 ( Passenger side at the rear). It's coming out of the square bolt below. I pour water in, and it comes out the center of that inside square looking bolt. I don't know the part number nor do I know what its called.
Thank you, I would appreciate any help.

It's a pipe plug you can probably get it at a hardware store or auto parts store,how many miles on it that water looks really rusty i would be thinking about a flush and going thru the the cooling system

Thank you Shamrock. I went to autozone and Oreilly's and the people i talked to never seen/heard of such a thing... go figure. I ended up picking up a set of squares at harbor freight and will be pulling it out today. I am not sure what caused it to blow, but it did in the center. Currently the truck idles rough, i pulled the plugs and they were all black, cleaned the throttle body which was also carbon'd up. replaced plugs/wires/cap/rotor. I connected a fuel pressure gage to the shrader valve, let the pump prime and the gage barely went up. Started the tahoe pressure went up to 62 psi steady, still a rough idle. I ended up ordering the updated spider injectors, regulator, fuel filter, gasket set. I plan on cleaning the whole intake manifold and replacing some parts. hopefully that will get rid of the rough idle.

I ended up having to take the pipe plug with a 7mm square head. I picked up an assorted set of pipe plugs from autozone and a 1/2" head ended up fitting in there with some permatex.
Letting it sit for a day, then going to flush the radiator out, hopefully that is the only thing wrong with it. Still unsure what caused it to go out.
I get my Delphi FJ105666 SCPI to MFI conversion today from amazon. Already have the Felpro gasket kit and bolts.
