Whats this part?

[WingZr0]

I'm trying to find the name of this part and it's part number hopefully.

It bolts onto the side of the Thermostat Housing on a 1977 280Z,

(California Model if it makes a difference).

Looks like a water inlet elbow

like this one on Ebay for a 520 and 521 pickups.

It's also shaped exactly this one right here.

I'm not certain, but it looks like the same elbow that goes into the rear of a 240Z cylinder head, just below the #6 spark plug. If so, the part number is 27195-E4400, my dealer charged me less than $7 for it last year (club discount).

Yeah thats what the Ebay guy said it was too, except the part I'm

talking about is about 1/3 that size but the same shape and look.

It bolts on the lower half side of the Thermostat Housing Block with a

2 inch rubber hose coming off it connecting to the Fuel Rail area.

I was afraid that you'd say something like that. I looked at my parts CD and don't find any elbows listed there for a 280Z.

It is a connector that goes to your thermal vacuum coupling.

Yep, Scrap what I said about the Fuel Rail area as I was going from

memmory on that.

The elbow goes where part# 45 is and is the one in this picture circled in

RED and centered in GREEN

I think you may be referring to the thermal vacuum switch/actuator.

Is that it?

A MSA rep said Cold Start Heater Hose but he was kind of

clueless though no foult of his own.

Well I can say at least coolant comes out of it.

my bad, I edited after you posted this. The part you are looking for (unless I am mistaken) is an elbow that goes from your therm housing to your vacuum actuator. At least that is what it does on my zx. Getting that little two inch bit of hosing on there is a real pain.

Thats it ! :classic:

Do they still sell that?

I got a replacement off a parts car at the yard but it's got surface rust.

Put some PB Blaster on it but I rather go new.

David is right as to what that part is but it's one of those mysterious parts that doesn't show up on the parts lists/microfiche. Nissan might still sell it but I was never able to find a part number to give them so I kept searching the junkyards until I found a good one. Use good quality hose and clamps when you do it becaue like he says it's a pain to work with and you'll want to get it right the first time.

Thyanx for all the replies guys

Welp, PB Blaster it is :classic:
