Can someone explain this engine bay pic to me?

What is the belt-driven accessory on the left? The car is supposedly an 80 SC, A/C delete. Also, what's the silver box up on the top that looks as if it's mounted to the engine lid?


Thanks and I look forward to the education.

Air pump, and rear window wiper motor cover.

Definately air injection pump for smog. I believe these started in '75 and I don't know when they were replaced with a better system. Perhaps not until the 3.2 in '84. Anyway, cars w/o cats had these.

Ok. I was gonna ask if it was smog pump, but I only thought that was through the mid-year cars.

So can I expect that this car has been run relatively hot for it's whole 80K lifespan?

The PO of my '79SC removed the smog pump and harware and gave it to me in a box. He claimed the car ran better after removal... As far as I'm concerned, he saved me the trouble.

I don't believe the smog pump would increase engine temps appreciably... You may be thinking of the thermal reactors used on some of the mid-70's cars before the use of a cat.

yes, remove the air pump, as I did--gained a bit of power but I also replaced the cat with a bypass at the same time so I can't claim that for sure. if nothing else, it's one less belt to break off and cause havoc in a running engine.

Yes I was confusing smog pump with thermal reactors. I guess I always considered it as parts of te same zany system.

Thanks!

Milt, the smog pump disappeared on the '80 model.

My 80' never had one, the heads don't even have a place for the air lines.
