The smog pump will not affect the as milage. Here in Wisconsin they are supposed to be connected but the kids at the test stations don't know a smog pump from hole in the ground. I would bet that Ca. would be pretty fussy abvout it.

Sal,

As I recall, the guys in the know say no need to use lead additive. Most call it a waste of money. Apparently no harm in using it; but not needed.

The so called lead additives really do not contain lead or anything else that will give a benefit......no additives necessary.

No lead additives in your 1931 and no lead additives in your 1967 El Camino either!

Yes, and don't forget to replace the Themo activated fan clutch, if you have factory A/C. I had one go bad after servicing the factory A/C and using it on a 350 mile trip for no telling how long the A/C had been out of freon. The A/C worked fine, but....the fan clutch froze up and knocked the bearings out of it and also the waterpump bearing after using the A/C in 100 degree weather,

Thanks for all the replies. I didn't think I needed it but it never hurts to ask. As far a A/C this is a 250CI six cyl. Just bare bones with a heater and a radio. It did get hot on me when I drove it home from San Jose. A 200 mile trip. The temp light came on so I turned on the heater and it went out for a long time. I had the heater off for a while and when the light came on again so I just turned the heater on for the rest of the home. I did talk to a friend and he thought that there should be a fan shroud on this model. So that makes sense to me. I will look in the service book that I have and see if it is missing. Thanks again for all the help. :vcca:

I believe the 6 didn't have a shroud. If the fan is about an inch from the core it not have had a shroud.....and at 60 MPH it should not overheat with no fan or shroud. I would suspect the cooling system is dirty. These did not overheat when new but the had a real thin core.

This does have a two row core. My cousin had some work done on it before he drove it to San Jose from north of the Golden Gate. One of things that is on the work order is flushing out the cooling system. The fan blade is more that one inch away from the radiator also. I could try flushing it out myself just to be sure. Thanks again for the input. :vcca:

I don't know if this helps but I have a 1966 el Camino base model CA car all it's life. It's a 230 six w/Powerglide and it has an AIR pump on it. Mine has a basic plastic radiator shroud on it. I assume it's original. I am the 3rd owner. And mine is very basic also. The only options: the bigger 230 six, Powerglide, AM PB radio, tinted windshield. No power steering no power brakes no A/C.

Note my Aug 7th post said the models with air pumps had a shroud....so it sounds right.

Well now there is some thing else to check out. I will have to see if I can find one through some of the catalogs. Thanks for the input.
